OK I have ownly heard of fitting a larger turbine wheel and making 355whp 14psi from doing this so i whent to my local turbo recon shop £400 gets me a T6 turbine wheel and a 20z comp wheel fitted machined out.
IM going to port the wastgate to 28mm do i need to go larger
Two porting exhaust manifold to match gasket
I have a full 3" exhaust No cat 99 oct fuel
Three make a 3" downpipe
Any help advice thoughts on this. Turbo shop says i will gain 200 rpm lag im hoping to reduce heat and make power without dropping off at high rpm

 

Look for posts for Lucky77, I think it tried something like this and he lives on your island

 

Lol yes thats where the idear has come from 355 whp but dident do the turbine wheel Can i be the first to do both ???

 

I would buy the mase or inline hotside and call it a day.

 

How big is the mase hot side keeping lag to a min. 430 whp with standerd exhaust with the mase sounds grate but i bet the lag is huge
