twin turbo GTA or AFR/cammed GTA Posted By: Archangel On: 02-10-2008 @ 14:59:47 Reply | Edit 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. --  '91 SuperRammed GTA "What does matter is that the current GTA carries on the idea of the first Trans Am proudly and deservedly.

Plus, I wouldn't want to loose the A/C in order to make it fit. Anyone else? -- '91 SuperRammed GTA

The TT would probably give better gas mileage. Ebay stuff is sometimes not the best. I'd go with the h/c myself first, then TT later. -- 1982 Z28, 383, D-1SC intercooled @ 10psi, trick flow heads, solid roller cam, 3.73's, stall 9.97@137, 1.48 60', 633rwhp@7400, 472rwtq@6800 AIM:CHATV400   Posted By: Remdog On: 02-13-2008 @ 20:16:47 Reply | Top | Edit AFR 195cc Eliminator http://airflowresearch.com/eliminator.phpor heads rule [ Edited on 02/13/2008 @ 20:17:32 ] Posted By: Archangel On: 02-21-2008 @ 08:46:22 Reply | Top | Edit I just wish they weren't so expensive.

I'm sure there are high 12 second passes with the heads/cam combo and good tires. -- '91 SuperRammed GTA
