power gains / help needed

Alright here is the run down: 1982 4x4 frame with 1979 2wd body sitting on 30's with a stock 2.6 with a 3 inch lift and crunk up torsion bars, im plannin on putting a starion/conquest turbo set up on it with a decent cam and a 2bbl holly with a custome equal runner intake . What kind of power gain should i expect? It will be a week end wheeler with a posible snorkel in the future and maybe some stock mine baja races , but mostly street driving.

hard to put a number on it - too many unknowns. Will it be blow through or draw through? what are the cam specs? turbo size and exhaust manifold stock, modded, or a header? Stock starquests were 140 - 188 hp with tbi injection. With the right combo - 250-300 hp easy. You may want to rethink the carb for an off road rig and a turbo - keeping the carb working properly will be a real challenge.
