Default OEM Gen IV parts to try out 1st... intake manifold with 90mm TB , hi-flow water pump
Before I even consider aftermarket, I think I'll try these
OEM Gen IV parts 1st...

LS2 intake manifold with 90mm TB
The manifold is suppost to bolt on a Gen III.
The 90mm TB is drive-by-wire, can vette TBs be fixed to work
on f-bodys ??

LS2 water pump looks good too... at double the Gen III flow...

race Meziere = 35 GPM
street Meziere = 55 GPM
Gen III = 80 GPM
Gen IV = 160 GPM

Hell that means you can underdrive the hell out of the water pump and pick up some decent power eg (50%). As long as your alternator can handle the task

I thought the stock LS1 water pump was 80 gpm. Meziere told me that their pumps are rated at less gpm then the stock LS1 pump.
