hia, i recently replaced my wrx engine after blowing the old one, since having this engine in it doesnt seem to pick up very well(turbo not picking up untill around 4000-5000rpm)once the turbo picks up properly it holds around 1bar before it boosts properly its only at about 0.5bar!?i did replace the turbo when i replaced the engine so could it be the turbo?it also has a slight missfire and the air flow meter is reading optimal on idle!?sometimes i get the check engine light on if i put the clutch down so it idles then it goes off, what could this be?

i know im in need of alot of help but need to try get it all sorted asap so it can be sold.

can anyone help me out on this?much apprecitated if anyone can.

thanks.

 

to me it sounds like a fuelling problem rather than turbo. make sure your fuel pump is in good shape. i would even suggest you should upgrade to an sti pump just to give you a bit of extra head room.

 

have you had the car mapped for he new engine and turbo?

 

firstly assuninf it is a classic? read the error codes and reset the ecu
how to

sounds like a possible exhaust leak before the turbo

sorry it is a classic and i havnt had it remapped since changing the engine didnt think i would need to as its the same as what was in it realy?

Either an exhaust or intake system leak sounds most likely....
