I think a machine shop can do fine work on a 7M without having specific expertise on the platform. It's nothing too crazy exotic. Although... you are in the part of the country where I'm sure there are shops that have very limited experience on imports of any variety. Anyways... In my mind the...

If you're aiming for that much power I'd go the extra distance for a good machine shop. If you're ok with lower 300's for whp then it's a simpler project. Above low 300's whp you need enough other supporting mods that I think it would be foolish to skip a proper block prep from a machine shop -...

Figured there might be a few new people interested in this after I got a request on my YouTube channel. I remember there were a few good write-ups years back, but there seem to be missing pics or hard to find links now. This tends to be near the top of "Best Cheap Mods". I did mine back in...

Got some gas after cruising with fellow forum member George yesterday. Even though it needs paint desperately, it doesn't look too bad with a quick cleaning of the wheels and some tire shine.

OP: I feel for ya. Emissions problems are a huge pain and expensive. Fucking California is making it even more difficult for you. Can you provide a few better pictures of the engine bay? They said you failed vacuum lines. I wonder if you have a loose vacuum line or something. If it's in the EGR...

I've run all 3 stock US options in the Mk3. Of the stock ratios I like 3.73 the best by far. In everyday use it's more practical for me. Lower RPMs, more time at full boost before shifting, etc... For autox you probably want something shorter, like a 3.9-4.3, but otherwise I'd stick with 3.73...

Lol. Woosh. ktothec: You need to start with some basics. Unplugging random components doesn't help you figure anything out. There's a process to figuring this stuff out. Check for codes being step 1. ;)

There's a good article on here about Fuel Cut. I should do one on my website, but haven't yet. Fuel cut is there to protect your from pulling in too much air for your ECU and fuel system to manage. The 550 mod tricks the ECU and fuel system into allowing more fuel to flow. This is normally...

Wow, that's pretty neat. Still looks like nearly a grand to get all the material and that doesn't include seats or rear plastic. Not to mention all the fitting. Good lawd all the fitting... I'd love to see a car finished with this though.

Got an 89 JDM Auto ECU. Plugged it in, no other changes. Car runs beautifully. Idles high when cold, settles just below 1000 when slightly warm. Plugged my old ECU (90 JDM Manual) back in and idle was low (around 500) and rough. Something's going on inside that damn ECU it appears. Anyone...

Do you only have this problem when the car is warm? If so, I've got something similar, but the car never dies. Just runs a little rough until I give it a little gas, then it's fine.

Haha, I was thinking the same thing. You know... that big sheet of metal shaped like a supra encasing the entire body of the car... lol.

Look at the TSRM. Small dabs of RTV where you circled. If that timing cover wasn't in place when it was machined you'll probably have a leak there no matter what. If it was machined, and is nice and flat, then the RTV should seal it nicely...

Thanks for that confirmation JJ. I have not tested STA since I had trouble last time. Mostly due to the corresponding trouble code never coming back. I went to test it out today and low and behold the car fired right up. Let it run for a while, shut it off, tried again and it started fine...

Update: Ran through the ECU testing portion (most of it) in the TEWD. Everything I tested passed except I'm getting no voltage on IGT and 1.1V on IGF with the ignition sw on. This seems to be a failure per the TEWD specs. From an old Jetjock post on MKIII tech it sounds like IGt voltage comes...

Stock headbolts are 100% completely fine. ARPs are cheap insurance and I'd recommend them on every build, even a stock GE. If your engine is already assembled with stock bolts that's perfectly fine. The low torque value is a problem, though. I'm surprised the mechanic was comfortable modifying...

Very jealous of that head unit. You'll have to let us know how it works out. Are you planning to use it with an Android for Android Auto? The USB panel deal is awesome as well. Appears to be the right general size and shape. Though, I'd prefer one in the windshield cleaner slot with a 90 degree...

Used an actual spark tester tonight. 1, 2 and 3 are barely firing once or twice then go completely dim. 4, 5, and 6 are much better - perhaps even normal. Coils show good resistance and no shorts. Coil wires are good. Spark plugs are good. Igniter is failing the test in the TSRM, but it's a...

Update: I have trouble starting again. It's been trouble free for over a year with consistent driving. This time, no codes are present at all. I tried to check spark by grounding the plugs one by one outside the cylinder and with my wife's assistance as the visual eye while I cranked. She...

Wow. I need to upgrade my audio. I've waited forever and just haven't done anything because I can't decide what I want and I have this high-end cohesive system in mind. In reality, I would have been better off getting something cheap years ago and upgrading if needed. Thanks for the motivation...
