    1000hp 7MGTE

    You think the a70 crowd is bad. Hang out on some Z31 forums. Most dont have the budget for a 300hp build, and that only requires a 3" turbo-back, intercooler (we didnt get one stock), and a boost controller. Electramotive made around 1000 horsepower on the stock crank before upgrading it for...

    My FFIM...thoughts on it?

    To the OP. What is the length of the manifold from the end of the number 6 runner to the end of the plenum? It looks like its terminating right at the number 6 port, and usually you want to extend the plenum past the last runner.

    your thoughts & opinoins on nitrous?

    Nitrous is like a hot chick with an STD. You know you wanna hit it but your afraid of the consequences. I spray 180 shot on top of 28psi on my VG30. All the way down the track.

    z31 300zx or supra mk 3

    Im not saying that its unheard of for a JZ, but factory in the cost of swapping a JZ into a Supra and throw that VG30ET, and your going fast. I spent more on my Motec M600 to run the car then I did building an engine (ofcourse i do all my own head work, and fabricated my own intake plenum...

    z31 300zx or supra mk 3

    Theres really nothing different between the Z31 Turbos and equivalant year Supra turbo. Z31's all had the option for power seats, leather, automatic adjustable suspension, automatic HVAC, digitial dashes, 205hp 3L turbo, 2 or 2+2 models, and T-top or slick top models. The Z31's are lighter and...

    Need help quick

    I'm at a friends house, and the positive battery cable just fell out of the batter (Side post, wonder GM idea). Apparently the person who owned the truck before me cross threaded the battery and it just now fell out. Does JB Weld conduct electricity? I'm an hour away from my house, and I...

    Head porting

    Anything is possible with enough time and money. So no, its not necessary to port the head, but simple things like 3-angle valve jobs, a nice back cut on the valve and simple port job can increase flow as much as 30%. Sometimes even more. Think about how much easier your life will be after you...

    86.5 MKIII SUPRA windows

    Toyota Service Repair Manual. I would suspect a fault drivers side switch then. They easiest was to test is to pull the switch out and test for continuity of the switch in its different positions. EDIT: Did a search and surprise surprise I found an online TSRM. I would suggest downloading it.

    86.5 MKIII SUPRA windows

    Which window is not rolling up. If its the drivers side, it could only be the master switch (driver side). If its he passenger side, then see if it rolls up from either switch. I could get into detail about how to test each one of the curcuits but without a TSRM, i would be giving you such vague...

    86.5 MKIII SUPRA windows

    I dont have an supra wiring diagrams sitting right in front of me, but 99% of the time if a window works in one direction and not the other, there is a problem with the switch. (Ofcourse this is the GM tech in me talking)

    anyone heard/used this oil filter relocation kit? HPF.com

    I use transdapt relocation kit on my 300Zx. No problems with it what-so-ever. However it is a cast peice and IJ is not the only person who I have heard of cracking the spin on adapter trying to take it off. The only other thing is, the Transdapt kit comes with rubber lines, which I'm not a fan...
