Heck, even an improperly one can make 300 hp easy!!!
Turbos respond to mods very well, sorta like a multiplier not just an adder!

Of course there are those naysayers that will tell me that I should just pucker up and buy a mid-'90's Vette and be done with it...I will promptly tell them to bite me...
Yup. I think with 6 psi I can see around 75 hp, particularly on the top end power band, which is where the 4.9 will need it. I am probably going to get an intercooler from Stoney, but I would prefer to have some measuements before I shell out any cash on shipping.
The only thing about the intercooler that he has is it seems to be a tad small. But in all honesty, smaller is better than nothing. And from what I understand, if you run too small of an intercooler, it will lower boost levels...N0DIH, is that true? If this is the case, I would think that would be good to controll boost with the particular turbocharger I am using.
If I need more boost, a mechanical boost controller can do the trick at around $25.00...Just dial in the regulator and go. I wish it would be able to lower boost, but from what I understand, I will need an external wastegate to do that. The device I am goinmg to order just increases it due to the fixed nature of the stock Warner-Ishi wastegate...If you know of another way to controll boost cheap (as in lower it), let me know.
