Hey, just installed a new jspec motor in my 87 turbo 2... at first i couldnt get it running, now it starts right up, but is slow to rev up, and slow to rev down. almost sounds like the timing is off or something, but its timed... both rotors are getting fuel and spark, and the motor has good compression. would a faulty TPS cause this? maybe a bad CAS? bad injectors? ECU ground? Engine ground somewhere? disconnected or incorrectly placed fuel/vacuum line ?

also, when i rev the car (i have to do so slowly because the further i press the pedal the more it hesitates almost floods) there is almost no boost. maybe a boost line is cracked? bad air flow meter possibly? i hear the intake gulp in air when i do quick throttles. im really lost here...
thanks for your help, Jordan

 

i also forgot to mention i have to fix the car within 4 days or my parents are going to make me sell it running in the condition it is, which means i wont get nearly enough for to buy another car. thanks Jordan

 

forgive me for the posts, im working on my car and coming back with new things i find...

the car is not really boosting at all... i rev the motor but there is no blow off (i have an ARC BOV)... could the turbo have gone bad from when i blew the motor? the exhaust side is not functioning any longer? i used a good compression jspec block and put all the manifolds and turbo from my old motor onto this new one. would a bad turbo cause this?

 

Did you adjust the TPS already...?

TPS Adjustment

 

Have you gunned the timing?&nbsp Are you using the J-Spec timing pulleys?

i have not adjusted the TPS, i do not have an ohm checker tool... and yes they are jspec pullies that came on the motor.
