Twin Turbo GTA or AFR/cammed GTA??
Hi guys! I just got some $$$, and was giviing a thought at a twin turbo system I'm seeing at ebay. The thing is, that for about the same money I could either install set of AFR Street Eliminators 195 and a CompCams stick or the twin turbo setup (limited at 7psi for budget limitations). The thing is, what should I do? The heads/cam swap would be pretty easy and straight forward while the TT will be a PITA. Both setups would yield about the same amount of horsepower (with the 7psi limit). The TTs would have more potential for the future, though. I don't have the $$$ to make the engine hold more than 7psi for now, but there's still the potential. Please list pros and cons for the setups like reliability, chance for an engine failure, budget, performance, installation....etc. I'll appreciate it guys. Also if there's anyone out there with turbos please I would like to hear your experience.

i'd do the heads/cam, i don't think you'd put together a TT setup for cheap unless you'd fab everything yourself. 7psi is pointless compared to hitting it with bigger boost.

TT is not exactly cheap, but neither is AFR Street Eliminators, New Roller Cam, etc. Well, I know 7psi is not much, but I figured it could lead to somewhere around 100hp since I am not running dished pistons and my engine has a healthy 210psi cranking pressure. Those same 7psi from a SC kit will add 100-125hp in an LT1. Compared to my current heads/cam, the increase in hp by installing AFR 195 Street Eliminators (85cfm intake/70cfm exhaust increase!!!) plus a new cam will be comparable to the TT setup. The NA setup will be safer for the engine, though.
