I wouldn't want the DSG or carbon fiber body panels so I'd stick with the base model.

Aside from the innate BMW sexytime, I couldn't see choosing an M3 over this fine automobile at this price.

56K I can see, 68K, is stretching it for a trans and brake upgrade but 98K just for bodywork :Q I think that's too much...

At 56K you're competing with C6 Corvettes 436/428. Understandable
At 68K you're competing with Z06, 505/475 or a Lotus Exige S

At 98K you might just be stretching it too far. 600hp Viper is probably the closest competitor because beyond that you're competing with much more prestigious badges like Audi R8s, 911GT3s and Aston Martin V8 Vantages. As far as performance wise, I'm sue it'll do fine but Nissan and even Infiniti doesn't have the badge prestige to sell a 100K car do they? I mean even for Lexus, the most prestigious Japanese luxury brand, a $100K car is a hard sell(A la 600h).

It'll be doubly hard for Nissan/Infiniti since a car with 90%+ of the performance will cost only $68K

I agree completely, previously I had heard ~$80K to start and that is way too high no one is going to pay that for a Nissan. But just shy is $60K isn't too bad and looks on paper like it might beat or at least hang with the competition in that price range.

Supposedly the new NSX is going to be well north of $100K and I think that is a huge mistake.

And thats not a Skyline. It's a G35 that looks like a Tiburon.

This is a Skyline: http://chrisnz.com/wp-content/.../05/GTR_NUR_R34_21.jpg



I'd rather have the R34 brought here as a 2008 US model than this thing.

huh...just swapping the turbo is usually how that's done, rather than playing with the stocker.

Many yanked the twin turbos of the R32-34 GT-R's to go single and still do.

The R34 was done in 2003, why would it ever be re-released as a later model? I love the car, but I seriously doubt it would sell in mass numbers in today's market.

My point is how much boost does the R34 run from the factory while making ~320 HP? There is room to play with the stock turbos and then upgrade to a single turbo when you run out of headroom.

If you want serious power you go single but thats like going all out with a twin screw or twin 67mm turbos on a Cobra. You can still go with BPUs (pulley or waste gate spring & boost controller, intercooler, intake & exhaust, tune) and gain 100+ RWHP with the stock systems on cars like the Supra and R34 that only come from the factory with 8-12 lbs boost and already making good power. So take those cars making 320 from the factory and bump either the stock twins or a single to 22 psi...

You upgrade the turbo when it can't make any more boost or flow any more air. 22 psi from the factory doesn't leave much room and if it's already that high, upgrading the turbos isn't going to see the kind of gain a RB26 or 2JZ does when coming from 12 psi.

In other words, I'd be excited if it said 400+ HP with no more than 12 psi. Already coming with 22 psi and making not even 500 at the crank doesn't leave much potential, at least not 2JZ/RB26 potential.

That would be like if my Cobra came with 450 HP with a 22 lb upper pulley... instead of ~420 HP with the 8 lb upper pulley it actually comes with.

Judging from the specs, I'd say they are significantly smaller turbos in the GTR than the R34 or Supra. For the setup to be pushing 22psi and only making 480hp, leads me to believe they are quite small.

That black Roush 2003 Stage 3 Mustang does have a supercharger

http://www.mpt.org/motorweek/reviews/rt2219.shtml

The 0-60 seems sluggish on that test, but the quarter time is awesome, I bet the driver was having a hard time launching it, or the tires sucked. It seems like an awesome deal for $15k. It has a pulley (?) mod as well, fwiw.

I wouldn't say the time is awesome, the trap speed is.

Probably only has 17x7" wheels or something. Some 10.5+" on the back would be my first upgrade. It should be more than 200 lbs lighter than the '03 Cobra (IRS=+125 lbs and iron block =+70 lbs alone on the Cobra) and is making similar power and probably a similar torque curve and on a better suited solid axle. The Cobras will do 0-60 in 4.5-4.7 and 1/4 from 12.5-12.9 bone stock @ 3665 lbs and IRS with 17x9" on the back.

Definitely seems like a driver/traction problem to me.

Is that 380R you linked the same as the 'stage 3'?

You could do a lot worse for $15g

Just get the engine checked out (plug condition, compression/leak down test) since it's got a pulley. Stay away if it wasn't flash tuned with every mod that didn't come from Roush (ie: big change in pulley size and no computer or fuel changes).

Yea that trap speed is definitely better than a high 13.

The Gen 4 Mustang Terminators always had problems hooking up with traction from a luanch with 390hp/390ft/lbs of torque. The Rousch shouldnt be any different, maybe a little better(solid rear v.s. IRS on the Cobra)

Fixable by slicks / 11" wide 18" wheels? 10.5s? Man do they even make 11s? Heh would be nice ..

Terminators have problems hooking up because of all the rubber bushings in the IRS that deflect like paper and allow the rear wheels to basically flex and point in every possible direction but straight ahead = wheel hop and no traction and costly repairs. Trying to launch well with the stock rear end setup is as frustrating as trying to stab someone with a rubber pencil and physically feels just about the same way.

About $500 in aluminum and delrin bushings, $400 thicker toe link ends, a pumpkin brace, thicker bolts to replace a particular set that are too small for the hole they are in, full length sub frame connectors, and some 315/35 sticky rubber out back and that IRS hooks as good as a solid, at least on the street with reasonable power. Just have $1500 for a set of axles or $250 for a 26 spline input shaft saved up before you do anything crazy, because those are now the weakest link. Now that the IRS won't yield, something else has to. Many just swap to a solid axle because it's a cheap and easy fix, but if you have the time and money the IRS can do wheel stands and shear wheel studs just as well as a solid.

A nearly stock '03 Cobra can run 11s no problem. The best known time that I am aware of on a bone stock Terminator is a 12.5 with standard issue Goodyear Eagle F1s which absolutely suck. Some Nitto 555Rs in the back with a good driver, intake, exhaust, and flash tune on a bone stock car should break you into the solid 11s all day even with stock boost.
