You can see my mod son my sig but i think once i do a little cam swapping and porting and polishing along wiht a conversion to mass air and upgrade a few compnents i plan to be near 400 RWHP N/A so if i get a 30% boost I will be in my range of what i desire so teh compression doestn really need to be that high.


I would prefer the engine to never see above 6500 RPM


I hope this is what oyu mean

Basically I want a really quick barely legal street car
(Also. i realized abotu teh fuel system upgrade i more ment how do i need to design my combo for optimum forced induction such as teh diffrent sizes of ports and intake choices, shoudl i upgrade to 75 mm thorttle body and not have to sell a 70mm when i upgrade evreything?

I dotn really got the money to buil agood motor then ditch nearly all of it and rebuild another one i woudl prefer to build a motor that woudl be quick but not the best it can be N/A and jsut wait till ic an afford the supercharger.

Thanks Guys

Your goal is 500-550 rwhp supercharged, you want have any trouble meeting that goal, but don't expect your block to last to long, unless you've upgraded it to something stronger. Anything around or over 600 hp at the crank on a stock block is about all you can get and expect it to last any length of time. A 70 mm tb is good to 600 hp, so I'd say you'll be fine there.
