Hey everyone. My brother has an mk4 and I'm thinking about buying his used turbo which has 3k miles on it. The turbo is: Borg Warner S362 FMW (forged milled wheel), .91 a/r, welded v-band by Full-Race. What are people's thoughts on this turbo? ---- My current is a turbonetics pt62 - making...

Hi all. I've been through a lot of struggles getting my a340e to hold 420whp in my 89 Supra. I wanted to share what I've learned through trial and error, research, and experience. I wish I had known some of this from the beginning...even having done extensive research ahead of time...

Hey guys. I have been troubleshooting my transmission now for about a year. I am running out of ideas and patients. Currently what's happening, is that the torque converter, for no apparent reason is locking up in third gear. Also, sometimes under wide open throttle conditions, shifting between...

I was in my MR2 the other day at a gas station. A kid in an rx8 pulls up behind me. We start talking and he says, "man, that MR2 is awesome. I'm a huge toyota fan! I love the supra's as well!" I say, "Oh nice, I have a supra too" The guy's mouth drops, " you have an MR2 and a Supra? That's...

I'm getting inconsistent speed signals to my aem ems as well as my suprastick. I don't know if the aem is in series with the suprastick. Anyone have this problem with AEM? Is it the speed sensor or a wiring issue? My buddy who has an MR2 (different builder) also has speed signal issues and...

Hello. I've been searching on the web and on this site for some time. I'm not easily finding a R154 swap thread. I'm giving up on the a340e and swapping into a r154 for my 7m. Looking for: 1) a Parts list 2) a build thread Any quick help would be awesome. Thanks in advance.

Does anyone have any suggestions for making the rubber/plastic trim look more like new? Specifically the trim around the windows, door vents, etc? Thanks in advance;

Hey everyone. Last year I had my motor built, installed an AEM EMS, and removed the 7m ecu. The AEM, for some reason, can only control the torque converter lockup and nothing else. So as it sits, I have to manually shift the transmission between gears (which is no biggie). When I...

Hey guys. I'm having a hard time deciding between turbos. Right now I have a JT62 Turbonetics bolt-on turbo. My only gripe is that it will only push 19psi (on days less than 80 degrees) and this is limiting my system to 420ish rwhp. It also doesn't hit full boost until 4500rpms. It crosses 16psi...

So I just did an entire engine build, put in a new wiring harness, and installed an AEM EMS. Car runs and drives amazing etc etc. The only issue is, under WOT it does not climb over 3k rpms if it's in drive for any gear at any speed. If I manually shift the auto tranny, it will hold gear...

So, I've had a question as to what my rear end differential is in my 89 supra. I've learned with the research I've done that there is a 89 version of my car, and then there were slight changes in the 89.5 to a few things in the car...and I was wondering if the differential might be among those...

I just had my motor rebuilt by a reputable performance shop, and then tuned by one of the best in the region. After picking the car up from the tuner, I drove it about 20 mins and then started experiencing an issue under mild acceleration. Under "light load" the car drives/performs well, and...

Is an 88 Idle Air Speed Control valve compatible/direct replacement for my 89+ idle speed control valve?

Hello everyone. I'm trying to prioritize what to do for this winter's budget. So far, I have all the power I'll ever want with my build...now it's onto other things. I usually run a budget of $5kish max/year. If you need a better idea as to what's in my car, check out my build link in my sig...

Hey Everyone. I am currently getting my motor built at a local performance shop. I wanted to take some guesses on how much power it's going to put out. Here is the current mod list that dynoed out at 402rwhp/408rwtq at 16 psi. I am pretty sure that I had some compression issues during these dyno...

Would it be possible to use a a340e off of a 7m for a 1jz swap? If so, what would it need? ECU & Harness? Any other mods? How about using the 7m auto with a 2jz swap? I'm considering parting out my build, and starting over with a 1jz/2jz swap. I have a built a340e auto with 2k miles on it, and...

Hello. My 7m build fell on its face...and I'm looking to go a different route...1j or 2jz. Leaning to 2jz. Since I have an artificial left leg, a r154 wont work for me. I have a built a340e rated for 700whp from my 7m. Ideally, I would continue to use this transmission since I have a ton of...

Heading up the highway today, going 70 in a 65...up in my rear view comes a silver colored vette c5. Once he gets close, he pulls in behind me, and follows for about 10 minutes...I think nothing of it and just keep driving. Just after we get out out of heavy traffic and the roads open up with...

Hey everyone. I'm strongly considering picking up a chassis for an xcross track car. I might even get into circuit racing locally. I'm looking for best overall performance + light chassis. Is a 90+ hardtop, r154, 1jz, twin turbo a good/the best setup? Let the input begin! Thanks in...

Riding to work the other day in the Soup...come up behind a State Policeman following a really slow CRV. I follow him for about 2 miles going 40 in a 55...and finally I'm like...this is BS :: angry :: So I say screw it....there is a 3/4 mile passing zone coming up...I pop out of o/d...spool...
