I spoke with the guys from Beefcake Racing and they say that the turbos are easier on the engine parts. With the exhaust driving the turbos, not the crankshaft, you don't get the shock through the engine.

Well, looks like I'm going to stay on the stock block for now.
I will be ordering the VMP Gen 3 kit in the next few days. I briefly spoke with VMP and they said stay with the 92mm (11 psi) pulley with the stock internals. They say the 92mm is good with 91 or 93 octane.
I asked Beefcake (I'm ordering the kit through him), and he said I should be fine with the 88mm (12 psi) pulley. I explained I only use good 93 octane and I have a good flowing exhaust (1 7/8" LTHs, off-road h, lethal performance OTA pipes).
I'd really like to go with the smaller pulley. I'm willing to gamble a little.
Thoughts?
I would stick with the 92mm pulley (11 psi). You will have more than ample hp/tq on your hands. And if your rear tire width starts with the digit...."2" , you will roast them. If this is for mainly street use, a 305 or 315 will fare better.
