turbos.....

[CJ_Derv]

Bigger turbos flow more irrelavent of Boost pressure most people think more psi more power incorrect, its all about the flow you can produce iirc, GT15s are tiny turbos so are pretty pointless, if you want a happy medium go for a hybrid T25 then you will have much less lag but will be able to hold boost into high revs, or as Ruan swears by a VNT turbo is the best way to go as you have boost right from the word go all the way up the rev range.

'diesel engines are famed for their low down torque not their high revving engines.'

that would be correct but we arnt running cummins engines which rev low and produce a lot of torque, gov modding a bosch to rev to say 5500 is still safe as others have proven its not high revs that kill these engines ruan dave and darren will back me up on this, iirc its excessive static/ dynamic advance that kills these
