Twin Turbo Ls3

[RSX302]

I looked at the LSX376, but passed on it. I figured with the LS3 heads and cam it comes with, limits its output for $6K. You would need to change the cam and do head work if you want to up it above 700hp flywheel. Then I wondered about the GM powdered metal rods used. pt#12607475. Then I worried about the LS3 heads under 800hp boost. Then I figured, do I really need an LSX block for 800hp? Then changing the cam would void warranty because GM probably knows it shouldn't go higher in HP..

SO! I just ordered an LQ9 370cu/in short block from Texas Speed.. $3200

I'm thinking I will put on a set of AFR215 heads and a cam that works nice for the street--easy 800hp with no questions about strength. This is with 10psig boost and 8.7:1cr non intercooled

I agree with you on powdered metal rods they sound suspicious and with my style of driving i don't think it will last.


You can call me the Terminator when it comes with driving my cars.

Ron,
What CFM are you looking at? Are you looking for the 700 CFM each intercoolers?

Ron,

I think my new set-up will be around 750-800hp. (~800 is the limit of my turbos) 800 = 1040cfm so I was wondering about the 450cfm units (pictured) x 2 to make up 900cfm? Too small? They use the 2.5" in/out which is the same size as my Banks intake box. My Turbo outlets are only 2" (1.60" I.D)

They claim up to 450cfm at .1 psi drop.. That pressure is very low..could I get 500-550 out of them with less than .5-1 psi? These units are only 13"x4"x3.5"

Also I should apologize; this should probably have gone into another thread. Didn't mean to change the topic.
