Hey fuzzy I can't reply to your PM as I don't have enough posts. I have decided to hold off this spring on a sports car. I am hoping next spring. Thanks.

I would suggest keeping some cash in reserve so you can pounce on something you like if it pops up for a good deal.

Color match is very close. My body work wasnt the greatest but on par with the rest of car. Ill wait a couple months for a nice hot day and Ill park the car in the sun to bake the paint - then Ill wet sand and reattach the rubber welting around the wheel well.

The ZII's hook up really nice. Cant wait till I have a nice warm day to try them out. The rears are scrubbing a little on deep bumps, so I need to do a little fender rolling/cutting. No big deal.

The snow is finally receding after a long, dreary and drug-out winter. We havent had a break from this "four letter word" since mid-October. The street sweeps are out cleaning all the fodder left on the roads from the long winter past. Many of the Garage queens are making their way out to the streets for their debut drive.

Today, I finally convinced my dad to go for a quick drive in the Mk1.5. It took a little convincing but he eventually yielded. I'm not sure why he has been avoiding the drive for so long, he never did ride in my silver MR2. I think he secretly is worried about my hobby, and doenst want me to hurt myself, or anyone else, so he doesnt want to encourage too much.

We finally got into the car and I took it easy for the first few blocks as he was seeming a little timid. We came to a nice open and vacant stretch of road so I turned on the Air to Water intercooler and slowed down to first. A quick 1+2+3 and I glanced over to see him gripping the oh-shit handle with this HUGE grin on his face.

"I saw that" I told him, and he quickly covered it with his usual poker face. Again, I wonder if he was just trying to not react with too much approval. We slowed down and went thru a round-a-bout to head back in the same direction. This time I came to a complete stop and then I laid my foot to the floor. It was probably one of the quickest 1+2+3's up to 120km/h I have done with a passenger, and this time I paid extra attention to his reaction. Same thing, he couldnt resist a smile. After slowing down to normal speeds he let out a short whistle of approval.

Dad really didnt have much to say during or after the jaunt, other than, "wow, uhh... be careful with that thing." He refused to drive it. I asked twice.
Made my day.

I walked into my garage the other day and found this.
IMAG0034_zpsbfa000a8.jpg~original


Nice little puddle of oil sitting below the front right strut assembly. Random burst strut. Click for video. .

Its no problem because I had a spare stock strut lying around that I put back in.
But this got me antsy to do something different.

bTime for a suspension upgrade.
-Ground Control Coilovers 250f, 350r - softer for street, but enough to track at my skill level.
-Ground Control Caster/Camber plates
-Koni Yellow Strut inserts.

This should allow me to lower the car a little, have WAY better handling, and be able to camber my wheels more easily as the stock set up really doesnt allow for a lot of camber/caster adjustment.

Also, while I was on my spree I ordered a LC-1 Innovative Wideband setup. This is in preparation for when/if I get Megasquirt PNP set up in my car. The Berk downpipe I installed last year has a bung for wideband already on it, so it should be easy bolt-on.

I put on a different muffler too. Its a Dynamax 3" inlet, "3 outlet. It sounds a lot better, not as loud, and doesnt drone. BUT, one of the baffles inside came loose and now all it does is rattle and sound like shit. Good thing for warranty. Should be here today.

Another side project I have going is a wire tuck. I bought a complete wiring harness for a Mk1, and a spare engine harness from a 93+ 3SGTE and am working on deleting all the unnecessary wires. My plan is to move most of the electronics to behind the drivers seat, and hide as many wires in the bay as possible. Its a little overwhelming at first, but Im only doing one wire at a time so as not to screw it all up. The trick is just making sure everything is labelled. I plan to make a cataloque with a list of all the colors of wires used in all the different areas so that if there is ever a problem (like a frayed wire) that it can be easily tracked down.

Its been a sunny +25*C around here for the past few days, so the paint from the sidevent mod is finally curing and hardening and should be ready for a wetsand soon.

Jlee had some issues with the LC-1 ended up going with an AEM unit and I just finished a massive build and I know the AEM can be used with MSPNP for mr2

I dont like to use LC1s because you have to pull them to recalibrate should a signal issue present.

Yeah, I wasn't a fan of the LC1 (mine died). The AEM works great but it doesn't seamlessly translate to the MSPNP. I may go with a Zeitronix eventually..I think that's what ATS has been using.

ORLY? Hmm. Shoot. It was $190 for the whole set up, sensor to gauge, all new. Didnt think that was too bad so I grabbed it. Ive read that the Innovative LC-1 has a faster response than the UEGO kits (like AEM), thats why I didnt get the one from twosrus. Oh well, we'll see what happens. Im really curious to see how stupid pig rich this thing is running, because I think its running stupid pig rich under boost.

Black2NA - is this massive build you speak of the "Because Racecar" MR2 you built?

Im still waiting for MSPNP to be released for 93-95 3SGTE. They said it would be about a month, two months ago. :herpaderpaface:

LC-1 gives great performance... it's just a bit fussy about calibrations. Put it in a place that's easy (relatively) to get to so that you can do the 6mo calibration without wanting to hit yourself in the face with a hammer.

Oh, and they aren't joking when they suggest mounting it on the top side of the exhaust... if some water goes through it could really mess up the sensor.

Edit: also, hooray more MS users on ATG!

Not the "because racecar" a 1991 mr2 turbo.it got a full built 3sgte and brandy new LSD E153 did it with a customer of mine 10 weekends...and to many hours should be a rocket once all tuned. Basicly what Jlee is about to undertake

oh, and the Berk Downpipe had a bung already welded onto it for the sensor. Its on the top half pointed in at an angle... I think I remember reading somewhere that this was an ideal location for some reason or another.

I didnt get a photo of it, but the main LC-1 plug thinger majing I just zip tied to the firewall in an easily reachable location.

I finished sorting out the Body harness on Saturday. Removed all the unused and unnecessary plugs and random wires that lead from nowhere to nowhere.
IMAG0113_zpseb31d5b3.jpg~original


Tonight I started on the engine harness. This was very interesting to do actually. First I labeled every plug. Then I stripped it of all tape and protective coverings. Then I deleted the unneeded plugs, one by one. I had to study the Engine Computer pinout diagrams for a few of them to figure out what exactly they were for and if it was actually safe to delete them.
After doing this, all I can think of is... what the hell was the guy that built this thing doing?? I mean, sure it works, but why did he make such a tangled mess of it all.

Here it is with all the plugs labelled and partially disassembled.
IMAG0086_zps96684234.jpg~original

Here it is completely disassembled and all the unneeded plugs in the background.
IMAG0110_zps327c5228.jpg~original


After I let my OCD take over organizing every. Now I can pick it up and lay it back down and not have a tangled mess all over again.
IMAG0111_zpsd6b92df3.jpg~original


Im just trying to source one more plug and Im set to start wiring it into the car. I want to try and make it so there is only one, or maybe two plugs in total that need to be unplugged in order to drop the engine. That would be ideal.

This is great, I now have all sorts of spare wire to use for future projects.

Recently Ive been having some odd oil pressure readings on the stock dash gauge. I was VERY concerned about this as I thought I may have damaged a bearing. The pressure would read very low, then normal under load, then sometimes would skyrocket after a launch. I did a whole shwack of research and reading on the MR2OC.com and came across a thread where someone said that this may be as simple of a fix as a bad oil pressure sensor - i didnt think this could be possible because the pressure sensor I installed was brand new.
Not wanting to risk it any further I bought a new sensor and an electrical gauge.
IMAG0131_zps127295b0.jpg~original


Now you may be asking, what the heck is all that for... well, it is highly recommended to remotely mount the sensor. This is because vibrations from the engine can damage the sensor, and also, this thing is HUGE and sticks way out from the mounting spot... I was worried about it breaking off if any force was ever applied to it. So a few extra $ put into a couple AN fittings and a 14" SS line and boom... remote mount.

The result?
All is clear! The stock gauge was throwing faulty readings. This new gauge reads a steady 45-70PSI depending on engine temp and load. Therefore, nothing to worry about on that department.

Also received in the mail was Ground Control Coilovers and Koni Yellow inserts.
Oh My Cow... what an improvement. The ride is a little more stiff but handling is significantly improved and I dont bottom out on larger dips anymore. Wheel hop is nil, launch is better, smiles are larger. I actually prefer these coil overs to the Eibach springs I installed on the silver car - it doesnt feel as bouncy.
The one thing that surprised me was that the ride height barely changed even with the coils at their lowest. Im suspecting the springs will settle some over the next few months though.
But man... its a whole new car.

Right now Im still working on the wiring loom and preparing it for Megasquirt... which has also arrived. I need to figure out where to mount my Intake Air Temperature Sensor... Seems to be a lot of argueing about where is the best spot. Some say before the throttle body is fine, while others argue that behind the throttle body-inside the manifold is best. hhhheeeh... k.

I put mine in my cold pipe. Wherever it goes, weld it! (the bung part, of course - not the sensor itself). I tried an allegedly very strong epoxy and it departed around 23psi. :whiste:

I have a bung that s designed to clamp onto a silicon tube. The silicon bung is 1/2 and so I need some sort of adapter.
I'm having a guy machine down the outside of the bung that came with megasquirt so that it'll screw down inside of the silicon bung. He says "it's gonna be effin' close but should work.". We'll see what he comes up with.

What sensor is it for?

an air temperature sensor. The stock IAT is inside the Air Flow Meter which I intend to remove... not the greatest place for a temp sensor anyways as its pre-turbo.
