basically just curious what yall think of the way im building up my sr. right now ive got greddy cam gears, greddy rocker arm stopper, Greddy vavlvesprings, Crower titanium retainers, HKS step 2 cams 272/272, still figuring out what valves to go with, Walbro 265lph fuel pump, precision intercooler rated to 750hp measurments 31.5"x10"x3.5" with 2.75 hose connections, and a turbonetics t3/t04e turbo .63 intake .48 exhuast. ive still got a few more parts to pick up but for the most part thats the motor just kinda curious what kinda HP levels yall think it might put out. oh and the head will have a decent port job done to it. as for the bottom end its staying stock for now.

If your sticking with the stock bottom end, your head build is overkill. What are you aiming for? Autocross response? Drag top end power? Sweet gear though

well the way things are looking the build on it should be pretty versatile the turbo should spool quick enough for autocross and allow for some pretty good power as well. i mean drag racing isnt my primary goal but its nice to know that youve got some balls when it comes to it. the head build might be overkill but i like overkill. the better the head flows and the stronger its built lets me worry about one less thing.

Nice setup, but I think you'd be better or with some 256 or 264 cams with that .48 a/r turbine. Turbine will choke engine at the high rpms needed to realize big gains with those cams. It'll be a killer setup no doubt, but I think you'll get much more out of it if you either go for milder cams or rev higher. But higher rpms may require a bottom end build. Sometimes 264 cams outperform 272 cams up to 7k rpm.
