Hey guys im busy with a turbo conversion on my bakkie has ca18de motor with garret t2.5 turbo compressor side a/r is 0.48 and exhaust a/r is 0.38 .ok the problem is the bakkie only revs 5500 doesn want to rev more but boost pipes as not connected yet but when it was normal aspirated it reved 7400 can it be that the turbo is to small or wil it be better if the boost pipes are connected
