vpc hardwire into a 88? it is the same as the 89+, you just need the pinout for the 88 car, which is here http://www.turboninjas.com/supra/maft/8%20-%20Vehicle%20Specific%20Info/MK3%20Supra/1987-1988/87-88%20Wiring%20Diagram%20Rev.%202.1%20(CRE).jpg just follow the guidelines for the 89+...

^ what he said. if the heater goes cold is casue these nothing it in. the heatercore is more or less behind the stereo so it will dump on the passenger side. could also be a pinhole in a hose, one that only shows under pressure.

theres still crap even in a GE application. do a goole seach and they dont last in any motor. the acura, miata, prelude, and even in toy trucks all say they failed within 2 weeks of install. a fel-pro, victor, or OEM would be a much better bet.

very impressive! almost as good as job as my 454

the Bernoulli Principle applies to fluid which doesnt compress like air does. the Bernoulli Principle would apply to hydrolic systems, but a turbo car is the same as an air comprssor. dont matter if its a 3 inch hose, or a 1/8 hose. 120 psi is 120 psi, the CFM rate will vary, plut pressure...

not a check connector, it plugs into the fuse box, as the ECU(EFI) and INJ fuses are in the underhood box. if will have to be spliced into the yellow plug,

im thinking its either a w55 or w56 from a 2wd toyota truck, or maybe even a celica.

yes that yellow plug is C1 on the 88 and under (yellow plug ECU) in 89 it went grey.

not that i know of. it just has extra wires for the vvti, but they run to the ECU, so the body plug shouldnt be to different. tis guy has the wiring pinout so maybe ask him http://www.supramania.com/forums/showthread.php?134137-1JZ-GTE-VVT-i-Wiring

heres how the VVTI system works http://www.wheelsjamaicahost.com/wheels_forum/index.php?topic=116411.0 voodoo magic explained as for cost, the vvti and non vvti blocks are the same, so swaping in is no more expensive. trying to twin turbo it might be a pain, id just go with a big single...

ok that should be the C1 connector that plug into the underhood fuse box.. http://www.cygnusx1.net/Supra/Library/TEWD/MK3/manual.aspx?S=Main&P=26 http://www.cygnusx1.net/Supra/Library/TEWD/MK3/manual.aspx?S=Main&P=27

the ignigter changed in 89, maybe its the plug for it? given its location by the altanator?

a lil rough but its workable, some bodywork and paint and she'll look like new again! oh and welcome to the fourms!

found this, hope it helps http://www.radlhammer.com/moving.htm http://www.radlhammer.com/car.htm

if you pull that plugged hose what kind of fitting is it? could have been unsed for a boost gauge port, though that wont show vac.

interesting concerpt,if the twin turbos fit. ive seen a few v8 swapped mk3s and not alot of room to work with. i was contemplating a supercharged 351 swap (f150 lightning motor) into my mk2, but someone wanted the motor so i sold it off. if you can find one might be a simpler way to go...

as grim pointed out, its not going to last along time with the high EGTS from a gasoline engine, unless you add meth injection to lower the temps. though maybe a new turbine wheel optimized for the higher EGTs could be gotten and swapped in

welcome, let me know if you have other questions.

yes. before the throttle body. i dont what the temp of vaccum is when the plate is closed, so i can only imagine its no accurate. almost every car on the market has the temp sensor in the plumbing before the TB. the temp sensor is internal on the stock AFM, my thottle response is a lil to...
