Right, just had the engine changed on the 2002 bug eye WRX! Done around 500 miles, I've let her boost a little before now and all seemed okay, yesterday coming back from a mates house I put my foot down only to about 5500rpm seemed to bog down a little bit, so I tried again and it would hardly even accelerate... engine sounds good and turbo seems to be spooling up but it feel like something is restricting it or making it bog down... engine seems on when rev'd in Neutral...

what could this be?

Thanks

 

Not an expert at all but has it had a running in map that might be holding it back?

 

No it hasn't, all seemed okay before I put my foot down yesterday then it wouldn't accelerate and just bogging down...

 

Split or loose boost pipe??

 

^^^ What he said^^^ or maybe air leak on the intercooler pipe.

 

Sounds like faulty boost control solenoid to me, do you have a boost gauge

 

Has the throttle cable been refitted correctly?

 

After all of that it was a loose knock sensor! 5 minute fix! Cheers anyways

 

Knock sensor ?
