that doesn't make you know how to work on cars anymore than anatomy and biology makes someone a doctor.

Your statement was a larger exhaust will result in MORE backpressure which I disputed. I never said backpressure is needed. That is a well-known myth. However; in proper tune some backpressure will exist, but it's not the goal. You then went into Bernoulli's and fluid theory then brought up 10 meter pipe to as an example for a automobles fraction of that length exhaust.

I have yet to see any posts about anything you have actually done with a car, it's as if since you bought your 'terminator' you became the car guru that doesnt' actually work on cars.

I have applied this kind of stuff first hand, I have been doing my own auto work as well as helping others with boats and cars for the past 20 years now.

 
Yeah because you're the only one in the world who works on his own cars and you can only work on cars if you've posted a 20 year documentary on the internet *hooocck spit* wank wank wank.

I grew up around cars, thats all my father ever did, always in the garage or at the shop as a kid. Granted I was more focused on computers than cars as a kid, you don't think I learned a thing or two or have exclusively worked on my own vehicles? I was rebuilding carbs around 7 (though I didn't know anything about them, it was just like a puzzle to me to keep me out of the adults hair). No I don't know every nut bolt and wire on every make and model vehicle ever made in the world, and neither do you, so off the high horse already.

I'd love to share my projects with you, but I'd have a feeling lamblast me for not using a torque wrench to secure valve covers and hose clamps or something stupid like that because you're apparently the only one who knows how to work on cars, as if it's a difficult thing for someone with the slightest motivation to learn in the first place :roll:

Come to think of it I haven't seen anything you have actually done with a car either, other than telling others on this forum that they don't know anything...

Fixing my IRS with real bushings (everything between the drive shaft and brake rotors) is likely among the first things I will be doing with my stock coupe, I'll be sure to take plenty of pics and post them here just for you. I don't normally take the time to step away, wash my hands, and play with a camera in the middle of something every 5 minutes just to please critical strangers on the internet who could care less.

As for my recent 'surge' in automotive interests that you've noticed, maybe it had something to do with actually owning a car worth tinkering with and talking about finally, because you know it's so exciting to talk about what I did with my 150,000 mile Camry last week :roll:

exactly. I have not seen much of any contributions here on car threads until that. I have been pretty active in a lot of those and have posted the work I have done many times. I don't know what makes the car 'worth it', but even back in college when I owned a Saturn coupe I tinkered with it. Link

Since then my 98 240SX SE has been something I worked on at link also my father's 96 Eddie Bauer 408 Bronco conversion Link. Link

Prior to those I bought a new 97 VW GTI VR6 at Link

And in high school, early college I had a fully restored by myself and father, 1966 Mustang GT at Link. After that car I purchased a 2 year old 88 Mustang GT since it was the last of the T-Tops. Pretty much the full motorsports package was put on it. There was also a 92 GS-R in there I had for a little while, it was fast but no torque.

I have replaced other's brakes countless times, did a R&R of an intake manifold just recently on a 200x Mustang GT that cracked, and currently most of my time is spent working on a house I just bought.

I have been doing alot more than just helping someone rebuild a carb here and there.

This reply is intended to provide insight into my own experience rather than participate in a e-peen contest.

Thats great that you've had so many cars to play with. I've got a bit of catching up to do in that regard, as I've said, the Cobra is the first really serious car I've had that I've been willing to put auxiliary money into (ie: above and beyond necessary minimal maintenance). I'm not about to spend $200 on an after market part for a car that won't matter when thats $200 I can put toward a better car.

Aside from maintaining and troubleshooting a 68 Chrysler 440 and a 95 Camry that I owned as first cars, my experience has been mostly with other peoples cars until the last 3 years or so with my Cobra. Most recently swapping an engine in a 97 Buick Skylark that warped all the machined mating surfaces from overheating and wasn't worth repairing unknowns when a used engine from a bone yard was about $500. The 3100 series GM engines are bad about cooling problems from what I understand.

And then again with a 97 Sentra that my sister got a steal on with a hole in the block and a missing rod (come to find that the transmission was shot; the owner had driven the car full blast down the freeway from Phoenix to Tucson with a slipping transmission the whole way = blown engine)

The first was done in my parents garage with a cherry picker (father being a career mechanic has more tools at home than god and air ftmfw) and the second was done at the shop on a lift. Both jobs from start to finish in time for a late lunch.

Maintaining the 95 Camry for 10 years introduced me to the wonders of working on FWD cars and how needlessly complicated getting to something as simple as a water pump or clutch can be. Nothing like pulling an entire wheel assembly apart to crack the bell housing open a few inches and unavoidably spilling 90 weight (god that stuff stinks) for what should be a 5 minute job.

Growing up I got to be involved with my fathers pet projects, a 58 Del Ray street rod with a 402 and a 64 Plymouth Fury with a 440 and OEM push button tranny. Along the way we've had a 70 Challenger and countless others that came and went.

My first serious car that I owned personally with my own money was the '03 Cobra convertible (because I previously had a long since expired fascination with the Boxster and couldn't shake the 'roadster' craving). I did my research and wanted a car with a reputation that was also modern and easy to find production parts for, and though I never really liked newer mustangs, the '03 Cobras grew on me fast for some reason. It came with BPUs like exhaust and intake and I did all the rest from used parts here and there as I learned the specific ins and outs of that particular car in depth (Kenne Bell 2.4 twin screw, crower cams, FR500 heads, fuel supply, e-mail order tune with in car wide band verification and retune requests, rear end bullet proofed, etc.) Thats the car that was good for probably ~700 RWHP though it's never been on a dyno to confirm or to the track due to the < 13.99 cage requirement for convertibles. I don't like cages in convertibles. High 12s stock, and with those mods it was an easy 10 second car. Enter my new coupe acquired this summer.

Now I've got a bone stock coupe and I want to go with a 325 cid (stroked 4.6 with 3.7" bore either on a sleeved teksid block or a Ford Racing 4.6 block with thicker casting for 3.7" bore) with twin turbos so I can enter my contribution to the Terminator community exploring uncharted waters (twin turbo is new enough, much less on a increased cid block). But first comes the boring but important stuff (oil, cooling, drive train bulletproofing, etc). I'd love to build the block from scratch myself, but thats just not something I have the expertise or machinery to do at that level of performance (not about to buy 10 sets of pistons to so I can perfectly weight match and hand select 8 of them them, etc, I'll let a engine builder do that kind of stuff and get a short block thats CNC balanced and spin tested on machines I can't afford to buy, much less for 1 build).

Most of the time you will find I speak in theory rather than application, this is true. But that's just how I am period, it's not just cars. I tend to avoid specifics and generalize to focus on the principle of the matter and if you were to 'stalk' the programming forums as well you'd see the same thing. I've coded on anything from my Ti86's Z80 to the PS2s EE/VU, yet in answering others questions I am purposely vague and general. Do I have any significant contributions or publications to those communities on the internet? No, because I do them on my own time for personal pleasure and curiosity, not to benefit an online community or gain fame and notoriety.

Cars, computers, whatever, after I mess around with the same thing in different circumstances, I tend to step back, postulate or learn the general theory and principle to explain what it was I was doing and why, and use that to apply my knowledge to unexplored platforms. 99% of the time, everything is always the same at some fundamental level. You should also find that if I am not absolutely positively sure about something that my info comes with a disclaimer stating such.

Not trying to get into a e-peen fight, but I seriously can not stand someone acting smug or telling me I don't know what I am talking about based on a 0.0001% mis-accuracy/technicality in page length post that is otherwise spot on. (seriously if you want to get into technicalities, check the pressure at the exhaust valve just after the exhaust event with a excessively large exhaust with poor velocity and a properly sized exhaust with optimized scavenging, you'll see higher pressure with the larger exhaust, but otherwise yes, at that point the exhaust system is so seriously screwed up who cares).

Anyway, :beer:
 
My bad, I just remembered the Skylark engine was replaced because the oil pump failed at the hands of a non car savvy driver who didn't immediately turn off the car when the oil pressure warning came on and the engine seized and the oil needless to say looked like mercury.

It was after *that* engine replacement that they let the coolant run low due to the radiator cracking a year later and decided to continue driving the car into the ground with low coolant and destroy the second engine -_-; :|

By the time they came to me to replace the radiator, pretty much every leak you fixed caused something else to leak. That person ended up getting a new car, and I pray for that car when the dealer service contract expires...
 
lots of explaination above...interesting how it was known all the machined surfaces were warped.

Anyways it seems you have lent hands in vehicle maintenance...it's a bit different than building your own car.

Also I won't be the only one saying this to you, but it aint a 10 second car until you have made a 10 sec pass. You have just joined the ranks of the many 'terminator' (I hate that moniker) owners that never race yet will keep adding more parts for bragging rights and armchair dyno their cars to four digit horsepower and single digit 1/4 mile passes.

Car modifications also are not about investments, often they cause a depreciation in the resale. They are about enjoying the car more while you own it.

This is going around in circles when my sole point was the reason too large a pipe diameter in an exhaust causes problems was not because it increases backpressure.

It was run bone dry until it either shut off from mechanical interference or the computer shut it down due to temperature. It was leaking from the intake manifold, heads, water pump, pretty much anywhere there were two surfaces mated together and a gasket. The engine was a lost cause.

Anyways it seems you have lent hands in vehicle maintenance...it's a bit different than building your own car.

Restoring a non functional car isn't 'building a car' and no I don't build my own tubular frames or body's from scratch or anything like that. By choice I let Ford, Chevy, Toyota, whoever build my car. I simply prefer newer cars so that:

A) they are daily driveable with no worries (in terms of being rare) and easily replaceable should something happen to them, and not feel guilty for letting a classic get wrecked

B) I can get replacement parts easily from anywhere

C) I can drive it *now* completed and ready to go and not have to hit bone yards and swap meets for 10 years to find a quarter window or a door handle. I went through that with my dad far too much to be willing to be patient enough to do it with my own cars

D) With costs of restorable classics going through the roof in recent years...

Being unwilling to do something knowing full and well what it takes is a different case than being unable to do something for lack of capability. Someday I'd love to tackle rebuilding an older car from ground up, but realistically with work and school, it's just not practical for me when I can get a completed newer car with a thriving after market and start from there at my own pace, and still drive the car daily in the mean time.

Oh, and I'm a mechanical and technical kind of person, building my own car requires body work and things I'm just not capable of or have the time to hone. Again I did that twice with my dad and the idea of spending weeks on end till 1am under a halogen flood lamp with sand paper, slide hammers, puddy knives, and welders just doesn't appeal to me. I'd rather get a car in good cosmetic condition and dig straight into the mechanical stuff. If I ever do engage in such a project I will seek to purchase a patched up, re paneled and primered rolling shell thats been straightened out and ready to go by someone who knows that stuff far better than I ever will.

Also I won't be the only one saying this to you, but it aint a 10 second car until you have made a 10 sec pass.

Fair enough. Thats what the coupe is for. Maybe you haven't notice, but since I got tech rejected for no cage and never got anything on paper, I've since stopped claiming any performance numbers or times and only talk about whats been done to it or what it could/should run in theory.

You have just joined the ranks of the many 'terminator' (I hate that moniker) owners that never race yet will keep adding more parts for bragging rights and armchair dyno their cars to four digit horsepower and single digit 1/4 mile passes.

So you have a predisposition of disdain for that specific car and it's owners, now I completely understand why I am your favorite target (this isn't our first run in). No offense taken now.

you are just the latest person I have witnessed thinks a car purchase gave them knowledge.

I don't know what ABCD were above, but when I was talking building a car I was not talking doing full restores. I was talking planning performance mods and doing that.

You seem to know a bit about the buzz words and all the toys out there, but twin turbos on mustangs aren't so new. Adding that extra ci to the engine is going to add a lot more cost and complexity to the build and if you aren't even using the power of the car you have now it's probably going to be one of those things that gets talked about forever.

I have a lot of gearhead type friends that have been talking so much stuff since high school when the rest of my buds have been through multiple cars.

Once my house is set to my likely over the next few months I am debating moving forward with turbocharging my 240sx or going to the 1988/1989 Porsche 944 Turbo I debated before I bought it.
 
I knew the car and what I wanted well before I got it. Having a fun car I guess just shifted my priorities and gave me cause to awaken previously rusty latent knowledge and update it post haste.

The twin turbo thing is fairly new to the '03-04 Cobra scene; it's not a mainstream well established exact formula like a pulley or a twin screw is. Pullied or twin screwed Cobras are a dime a dozen, turbo Terminators not so much, it's mostly uncharted waters. I want to do something that doesn't have 100 guides or endless reference points. Yes it's going to cost, I'm figuring $8000 for billet short block, $4000 in head work, and $8000 in the complete turbo package with ready built plumbing and fittings.

Ironically I'm in the same boat as you, relying on funds from an upcoming housing sell to jump start the project. In the mean time I'm educating myself on various combinations of compression ratio, boost, octane, quench, etc. and figuring out what will suit my desires.

Yes it will probably make over 1000 RWHP on pump gas and low boost (~18 psi +/-) and yes it will probably be a dyno queen and STILL (compared to twin screw cars making less power) only run 9s or 10s because I have a soft spot for retaining the 6 speed and IRS and yes it will be a total and complete waste. But it will be damn fun to build, ridiculous to drive, and I'll have fun doing it, thats what counts.

As for the money, I could do a lot worse, like spend $6,000+ every year on top of the line parts to play video games and watch it be worth $200 in 3 months like I've been known to do... but meh, money is just money. Anything beyond eating, sleeping, and procreating at the biological level is strictly for our pleasure and entertainment as far as I'm concerned.

I hope we can get along in the future. My recent and sudden (i.e.: the last 3 years) shift from computers to cars as my primary hobby seems to have alienated me from my geek friends who don't really care about cars other than that it runs, has a CD player, and doesn't cost a lot in gas. (It also explains why I talk so much about cars in a geek forum)
 
it's cool, but spending $8000 for a kit is not putting you in unchartered waters. I would read some of the available resources because 10's shouldn't require an $8000 block nor $8k in turbos.
 
Actually, we tested the engine compression, and it ran fine, gears all seemed fine, and the clutch was tightened, but it didn't take long for the extra damage to show. There was no muffler mods.

Anyways, the car does get 40mpg, and has a good engine in it. I do admit though I was stupid for buying it. The car was not worth 3k, which is what it has now cost me. I do believe though, that I can get another 3 years out of it, which will coincidently save me from putting more miles on my truck.

Nah, but my primary goal is low boost and pump gas. What power it makes and what it can run is whatever it happens to run when it's done. Most of the really really fast Cobras are running 26+ psi with 117 octane with basically a big blower on a stock car with little else done to the engine except for supply the blower with air and fuel and going to town with boost.

Relying on head work, displacement, etc. to find the power elsewhere with less reliance on boost and octane so I can run 24/7 on 91 octane pump gas (otherwise in my book it's not a street car) is what is making it expensive.

Power wise thats the kind of stuff you'd have for a 8s or faster all out race car, but like I said, 6 speed + IRS in a full weight factory trim street car I don't have my hopes too high on being the fastest at the track by any stretch. On the street as a daily driver on the other hand... and it will be well overbuilt with some margin of safety for longevity at the mechanical level, as long as the tune is good.

If I end up managing a 9s build and it takes 1000 RWHP when a blower can can do it with 300 RWHP less, thats fine by me, if I can gas up at the Shell on the way to the track. Street car.... pump gas... no methanol, nitrous, or race gas... thats why.

And a pre built kit, like I said, I'm not a welder or metal worker, I just want to buy some parts, get out the tools, and go to town. I'll let the people who bend pipes and weld flanges for a living do the dirty work.

It's going to cost a lot because of my pump gas mandate with a small displacement DOHC engine.

It's still going to be slow because I like IRS and manual transmissions and it will be bouncing off the rev limiter half a second after each shift.

Go figure. 😕

My sights are on the fastest '03 street class Cobra on pump gas. I'll build it, gas it up with 91 octane, get a dyno tuning sessions and wring the most that I can out of it. What RWHP it makes and what time it runs will simply be what it happens to run when the latter goal has been met.

I'm cutting myself *a lot* of slack and headroom for the 6 speed and IRS keeping it from breaking any records, even though there are cars like this that are examples of turbo'ed Terminators maturing. Thats a pump gas car on IRS + 6 speed. On the other end of the spectrum however you have many cars like this that run high ETs for the power they make and it leaves you wondering is it the driver, traction, turbo lag, a baseline tuned shakedown pass, or all of the above.

Only one way to find out, build my own.

He probably did nothing but WOT power shifts and ground the synchros to shit and dumped the clutch at every light and pinned the shafts with torsion loads between the engine and wheels putting excessive lateral loads on the bearings, and after that it's no surprise the mounts went too. If the mounts were bad, it was basically the shaft bearings carrying the load of any off axis transmission movement. Poor car.

BTW like your title "tried to rice out". Ricing something out is bad enough, but "tried" to rice, is the ultimate FAIL!

Sounds like someone's been watching too much Fast and the Furious*!

What really gets me is how you spent $3000 on such an old car... I don't know why you thought it was worth that much 😱.

I think thats the whole point here... it was only supposed to be a $1500 car that ended up being more trouble then it was worth due to ricers beating the crap out of it.
 
Yes, so by the time the mechanic was in deep, if I bailed all together on fixing it I would of still owed him for his labor. I felt if I was going to drop 500 on labor, I might as well drop the other 1k and just get it all fixed.

So, I got 4 months out of the car before I had it fixed. Now I just need to get 2-3 years out of it, and I will come out ahead. *sigh*
