Hi people.

Was just wondering what are the capperbilities of the standard manafold, reason for this i am planing on doing intercooling piping the oppersite direction to the normal kits but is the stock manafold going to needed to be replaced further down the track in serch of power. I gess what i am asking is how much power can it make before it needs to be replaced

thanks.

I have read that 350-400 BHP is where the manifold starts to show restriction. Basically on unless you build your bottom end a manifold (Greddy) isn't worth it.

The Best we have seen from the stock rb25det exjaust mainfold is 235 rwkw with Gt3040 turbo running tial sport external gate, and i was told by my tunner that i was not going to achieve any more hp with this manifold. :wassup:

he is talking intake manifold... or plenum for others.

I've got 270rwkw. and other i know making 300rwkw still use the stock item.

thanks for the info guys. Any comments about the the way i want to run the intercooler piping( in the reverse direction, up over the front of the engine first then down into the fmi then from the fmi back to the manafold

The 120 degree bend at the throttle body design is better. There are plenty of posts on why, do a search:cheers:
