No, its a stroker kit, the same as an rb30 is a stroker. fitting a 2.8l stroker kit to an rb30 you will end up with a 2.8, and have to get rods made to suit the crank.
Interestingly Morrie form HPIAB said that the trimmed version with the bolt on exhaust housing performs exactly the same even though"it only a few mm trimmed off the exhaust wheel"(his words not mine, and said the whole cropped thing is a joke. Interesting considering he sells turbos!
the above = unlimited boost.
Stock ECU R33 with unlimited boost = cough, splutter, backfire at about 11psi (well apart from **RB3530** - his one is a little special)
I think you mean cough,splutter,bang as the exhaust wheel leaves the equation
Water spray on anything that makes heat, diff, gearbox radiator, oil cooler, intercooler, just do some ghetto setup with irrigation sprayers, $100 spent here could easily save $$$$'s Hope you have an oil temp gauge.
