The bolt on sports turbine twin set up for the Z isnt going to get 660. You can achieve maybe mid to high 400's but not 660. Going by the post you are quoting. There has to be more done to get above 500 than just bolting on turbos and an intercooler. You will be restricted off the rip from fuel alone. Stock injectors are only rated at 440cc......for starters.

The trouble you'll inevitably run into is trying to set your boost too high without having enough fuel....run lean......destroy pistons and rings. The internals themselves will handle the load, if the rest of the equation is correct. Burning rich wont hurt internals, but your power will be limited until cams are changed. Engine response wont increase until the crank is changed. The only stock engine part that will give without over boosting and frying a piston will be the head gasket. And that is a guarantee.

As far as what was said for bolting on different turbines to the R and getting more power cheaper......ahhhh dont think so. Its rated at 500hp already. So youll already have to go bigger than the HKS 2530's to generate that. Not just a simple turbo change out and get more HP. With the old inline 6 you could change out the manifold and run bigger twins with ease. Not with the current engine used. Gotta change fuel delivery, different manifolds, larger than just a sports turbine, and most importantly get rid of the rediculously small intercoolers. I think the water cooler at work has more heat transfer than those rinky dink things.
