Just rebuilt my sapphire cosworth, when its running it just feels like a standard 2.0 it has no boost. This is what ive done so far - NEW AMAL VALVE, RECON TURBO & NEW WASTGATE, before i throw any more money at it can anyone help me. Its running standard ecu, injectors etc But has a mongoose exhaust thats the only engine mod!! Its doing my head in

 

u say no boost at all? in any gear?

 

have you preloaded the actuator, by about 1/3 of a hole?

 

welll nothing in 1st,2nd or 3rd. A little when your nailing it in 4th & 5th but nothing to shout about

 

does sound like either a boost pipe come off, or the actuator is not loaded up making it open at the first sign of boost and dro[p teh boost off...

 

How have you pre loaded the actuator???

Is it a standard one and not a -31???

 

have you got a boost gauge fitted?


as above sounds actuator preload should be 2-5mm, or mega boost leak, or blockage in the intercooler.
