Ok here it is I have as the title says. had to replace the original motor, changed to a Y8 block and a Y7 head, did not change the ECU or throttle body. the car now throws injector codes, and smoke rolls from the tail pipe and has no power really... I need to know if i need to change something else to fix the problem at hand,

 

did you swap out the injectors for obd0 injectors??cause the obd2 injectors will not work

 

No, everything else is original the only things that were changed was the block, the head and the dizzy.

 

well im not sure then i know the y7 and y8 have a air chamber set for the intake manifold and the head what intake manifold gasket did you use. Im not sure if this is the prob or not but it will be a start

 

also any codes?how long as it smoked ? did you just finish the swap?

 

ok its my sister car here is the deal my buddy used a y8 block/y 7 head he did not use the y7 intake manifold he used the manifold off of the old d15b2 which was dpfi the car is smoking like crazy and there is water seeping out from the head where the intake manifold mates up he also used the original ecu for the d15 b2

 

well it sounds like the intake is not bolted tight enough. did he use a new intake gasket? for the b2

 

no he didnt use new gasket, will that cause the smoking? and what ecu should she use? the intake mani is dpfi and the head is mpfi he did nothing to the wiring

 

try a new gasket and the ecu that came with that car will work for the motor

gasket is like 10.00

and the intake makes the car mpfi not the head
