I have been doing this swap over the summer , since I have started I have made enough progress so that I can start the motor and it runs but not to well. I am still running 3" downpipe and going to do the exhaust next week but im wondering if that could really cause the problems i have now. I can start the car when i push on the throttle and it doesn't idle very well. I have checked the fire and its good, its getting fuel, and I have sealed a leak and since then it runs better but still not good.. there is a hose on the intake manifold that goes downwards that i don't know where it goes, its just cut and it pushes air.. when i removed my air pump it stopped pushing air .. can someone please tell me where that hose is supposed to go ?

I also got the car moving but it doesnt have power.

checked the apex seals and six good puffs so i have good compression , we put a boost gauge and goes to 5 psi when im running open downpipe ? if anyone can give me advice to where to start going next or any info that can help me and if you have any questions about my car or the swap let me know thanks !

 

For the hose to nowhere I bet it goes from the air control valve to the catalytic converter.

The first things to check on these is vacuum leaks and TPS calibration. Once those are proven perfect (not ok, good, great - but perfect) then you can move on to other things.

Good luck with your project.
