hi there lads.

i have recently fitted new g/box and ready for hitting the road, i have tried it on the road however the turbo will not kick in now as soon as hit 2500 the car will not pull. it does this when the engine is cold but it was left to warm up on the drive for at least 30mins. also the box seems to be clashing with the under car every now and then like a knocking.

can any body help me here?? all advice well appreciated!

thank you very much

 

The lack of power sound like a boost leak, check all your boost pipes.
as for the knocking sound, have you checked all of our bolts are tight could be as simple as that.
hope this is of help
