Stock vs Stroker with BOOST !
I wanted to see if anyone would like to share their opinion about building up a motor for boosted application. I plan to run a large single turbo 76mm GTQ or perhaps even a 76mm GTS.

If you look at the fastest turbo cars on this board they are all either stock cubes or all bore combos.
Leave the 402's for the blower guys. Turbos seem to like bore more than stroke. With a turbo you'll have plenty of torque without using a larger crank.

The larger cubes will help you get going until your boost kicks in full. Plus give you more power. Look at your power as a ratio. As in something like 2 HP per cubic inch. That will net 80 hp more than the smaller motor at the same boost level. You will have to decide if 60-80 extra HP is worth the extra $$$ for the crank. Or you can make the same power as the smaller motor, but with less boost.

Well lets put it to the test ...
I happen to have a set of Diamond LS2 9:1 CR pistons and I'll try these out with a set of carillo rods and stock crank and AFR Head. While im in the process of dyno testing the turbokit, I plan to use the current LS1 motor to house a nice square 402 bore & stroke. We also plan to dyno the 76mm GTS vs the GTQ with both short block applications. This should base some great conclusions as to those who plan on putting a single turbo on the stock motor vs a built stroker & which turbo charger will best frame the goals of you're street / strip vette machine.
