Well I finally figured out my problem with my wheel hopping and shaking. Changed ball joint, stopped for about 3 hours (ball joint did need changed anyways). Well it got so bad that my front end was shaking and started pulling to the right bad. When i stopped at a light i had to step on the gas...

Yeah thats why I used "in theory". But since I have a boost controller it should still boost @ 11psi i thought? The only difference should be manifold pressure? Could be wrong tho, happened once before :biglaugh: I forsee FCD or probably a VPC/maftpro in the near future :evil2:

I'm borderline on fuel cut (11psi), it shouldnt matter because the turbo will still be spooling at 11psi, but i will gain more psi in the intake manifold, correct? Therefore, in theory, still not hitting fuel cut?

Does anyone know what the pressure drop of our stock intercooler is? I thought I heard it was like 3 lbs. Just trying to figure out how much HP i can expect to gain. Anyone have dyno sheets for spearco replicas?

Paint code 167, duplicolors web site doesnt have it, I'll try paintscratch

Anyone know where I can pick up spray paint in supra color codes...online or in stores? Autozone's toyota selector for duplicolor goes back only to 1998.

Is that the most user friendly piggyback system? IE the simplest to tune?

I see that horsepowerfreaks.com has a maft-pro unit for $396, what else do i need, at that price wouldn't everybody be using it? :aigo:

Thank you very much! That is what I was looking for! I appreciate your reply!

I dont need the main harness, temp sensor or any other sensors? I just want to make sure i dont buy something i cant use, or have to buy more stuff for.

anyone?

Don't the VPC for the 7m come standard with 440cc chip in it... guess i should ask the guy. Also, Don't i need a wiring harness? HKS doesn't list one on their web site for the 86-92 supra.

KERO - What is the "wet-noodle" syndrome? FIGGIE - Do walbros fail often? What is your reccomended fuel pump? I started this thread because the 7m engine deserves a lot more respect then it gets. It IS a venerable engine no matter how old. Think about this - DP w/ 3" elbow and full three...

So would a port job be a good upgrade for the 7m head?

OK, income is a variable, but the guy running 817rwhp or whatever has to have sunk a considerable amount into his 7m. I am just sick of people saying "oh no way! You have a supra turbo! oh wait....its a mkiii." If i can, however, take them for a ride they change their mind, and with only a 3"...

But we COULD make that much horsepower in theory correct? I know that one of the reassons is we are limited on how big we can port due to some issue with the valvetrain, but i can't see where it would account for 500hp.

Maybe somebody can answer this for me. I always think about this.... why are there 1500hp 2jzgte's and the highest i've seen a 7mgte is 1000hp or so, in that dragster? What could make up for that 500hp diference? Is it the head? If so why can't we port it to match the flow of the head? Is it the...

Need someone to do an auto-manual swap. Are there any mechanics around toledo, that will do it, and have access to a lift? I thought about listing this in the wanted to buy section but i'm not really wanting to buy a mechanic lol

You HAVE to drill out/bypass/eliminate the J-tube if running a walbro fuel pump, or upgraded fuel system. The small hole will cause too much backpressure and your car will run rich. So there is no real gain, but is a necessity when upgrading your fuel system. If worried about stock FPR, buy an...
