just finished my swap took it out for a test drive. car starts up everytime but when its cold i have to give it gas.
when im driving it on the road the car has no power under 3K RPM and sputters and is hesitant you can also here
a popping noise from the intake even at idle. when the turbo starts to spool i feel a little bit more power but starts to bog at 4.5k rpm and is kinda hard to get it past that. checked to see if all cylinders are getting spark by disconnecting the coil packs one at a time and they all seem to be working fine as far as that i dont know what else to check to diagnose the problem.
current conditions of the motor that i currently know of
-i have an exhaust leak where the cat and exhaust meet i used a paper gasket i will be switching it to
a metal gasket today.
-water pump has a really small leak.
i will be picking one up for $5 today worth a try i guess for the money and i dont have to wait for one to come in
-my wastegate isnt hooked up to any vacuum source (dont know where to plug it into)
things that i think are wrong
- timing could be off?
-boost leak? which i checked for but couldnt find anything
-another exhaust leak
-restricted by my stock exhaust. i have a 3 inch down pipe and test pipe connected to the stock exhaust which was just for test driving the car
i would greatly appreciate your input
thanks in advance
