t2 vert swap problems
ok heres a question I own a 88 vert and I swaped in a s5 t2 I rebuilt the motor and im using an s4 wire harness with an s4 comp with s5 injectors. The car does not have the resistor pack so the computer and the injectors should be fine being that they are high imp. right? reson being is because Iv been trying to get it started all day i ran for a little but wouldnt idle then after that starting it just back fires and puffs smoke out wont start. The motor is makeing 110 in the front and 120 in the rear.

1. Why did you use a S5 motor in a S4 car. S4 parts are more accessible (IE: housings). On top of that are you using a S4 Turbo ECU or a S5 Turbo ECU. Unless you went pre-mix your OMP may not be operating since its electrical and most likey your in fail safe because the computer thinks the OMP is inop.
2. Be sure all your wires are connected properly and if its a jspec that you have the fuel hoses connected right since they are reversed on the jspec. What AFM and sensors are you using as well?

IF turbo EM harness, then did you do any alterations to the two orange colored plugs on it that connect to the Front harness?
And IF turbo EM harness, what did you do for the wiring to the alternator?

Used a series four Tubo ECU ????? and Turbo boost sensor??(the na sensor does not sense boost) and turbo afm????
If it is a non turbo ECu then it thinks you have 460 injectors instead of turbo 550's. Just guessing here.

how did u test for compression? because 110 and 120 if they are totals and not individual pressures could be your problem. pull your plugs, clean them, crank engine without fuel pump and/or injectors on until clear. then squirt some atf into the leading plug holes. reinstall everything and restart, when it starts be sure someone in the car keeps it running, and hold the idle up at 2-3000 for a while. my rebuilds usually take a good 20-30 min to clear out real well. also if you have any vacuum leaks and whatnot they will stop it from idling any lower. try that stuff hope it helps.

The compression tester is completly useless if the valve on the compression tool is not removed.
You need to throughtly check the Turbo swap threads before you continue or you'll find your self in a large money pit and no driveble car. Stop everything and do a search on turbo swap and read everything you can gather.
