Okay guys, i have a 91 Beretta and i am going to boost my 3.1 V6. I already got alot of parts and was thinking about to run some more boost than stock and get bigger injectors (from a 3800) and a garrett GT28RS turbocharger. I was hoping for 250-300hp with around 10psi of boost.
Now i wonder how much power i can get out of the "stock" turbo parts with the T25 turbo. Could i see 250hp with some more boost? With like 10psi too? I think i should get a difference from a stock T25 turbo to the GT28RS but i was just wondering.

I would think that with the GT28RS, bigger injectors, AND a good tune to make it all work together should get you into the 250-300 hp range.  I might also recommend a cam to help take advantage of that setup.  The Crane H-260 seems to be the cam of choice for moderate gains.  Someone used a H-272 but I thought they had some problems idling, it loped really bad (which IMO sounds cool as long as it doesn't die).  Can't really say what they make stock, again a good tune can do wonders.

Yeah, I just couldn't figure out a way to work in the one member who claimed that adding a valance to his lightbulb kept it from overheating...
