A friend of mine did the LSX swap with a 92mm turbo and i was lucky to have also worked on it. here is a vid of it and let me know if i can help with any questions.
LSX 427ci and 92mm turbo, roll cage, Asanti 22's with custom- body matching paint, lowered with H&R springs, Eibach sway bars, vented front fenders, factory gfx, Twin disk carbon fiber clutch, Barton shifter, 1500hp axles, PLX gauges, Ported L92 heads. Tinted lenses and windows, bow tie covers.
Stared in BATTLE OF THE SUPER CARS on SPEED CHANNEL vs a Mustang with 1000rwhp ( you can view the episode on HULU also)

Nice looking vehicle, thanks for sharing.
Is that the GM LSX or an aftermarket block from RHS or HKE?
I'm doing a LSX 427ci. build as I had planned to forge the LS3 that had 7.5psi. of boost, but before I could get around to it one of the valves bent and did some harm, turns out slightly more expensive just to go with a new block than to forge the LS3.
Wondering about the heads though, are all the assemblies re-useable in LSX-LS7 heads, and are valve covers re-useable too? Also, would the new LS7 heads requie machining or can they be bolted directly on the LSX block? I know the LS7 heads have the 6 bolt configuration and have rectangular ports so they are stronger and flow #'s should be good, and are also well suited for high boosted engines.
The plan is to go with:
GM iron LSX block
GM LS3 or LSX-LS7 heads (depending on whether or not existing heads can be used; One is damaged in the valve port.)
Callies Dragonslayer crank
Callies pistons rods
Solid stainless valves (heavy duty)
And, all the other typical bolts, etc....
Would you suggest anything different or a "might as well" considering rebuild anyway? We're expecting a moderate 800rwhp. with a slightly more aggressive 91 octane tune with this setup. What about timing chain, etc....?
The vehicle has already been setup with a dual fuel pump, ProCharger D-1SC, head assembly (duel springs, crane rockers, etc....), blower CAM, headers, Catted 3" exhaust front to back. We were making 680rwhp. before it went CAM was very effecient.
Sorry, for so many questions but obviosly very nervous about this build as it's going to take some time and as you may already know very costly.
