You do realize there several classes that require a 76 as the largest and those cars are making probably twice what your car does and spool the same. Just because you tried an off the shelf gen 1 76/75 precision doesn't mean you can blanket statement all 76's are the same. Jake Conant was running a class specific 76mm and his trap says he was putting down north of 1300rwhp through an auto.Which 76 you want to compare? only like a dozen of them. 76/75 is a downgrade for me. Bought installed, tested, removed. Housing swaps, ect. Not spending $3,000+ extra. Plus the cost of converter change and refab. Other ways to spend the money wisely. There's more to it than just a simple turbo swap. Ever drive a 88mm with a 1.40 housing connected to a 281ci on the street? I mean crap make 1400hp on the dyno - should be good for the street right?
