408W twin turbo advice.

Looking to building a 408w twin turbo. Need advice on which heads and turbos to go with. Need setup to be very street friendly. Block will be either iron dart or world products with all forged internals. Not looking to spare a dime on this build. Fill me in with some of your guys knowledge. Motor will be attached to a what will have to be a builit proof 4r70w.

Afr or tw heads. 205cc runners. Twin 67mm turbos will get you to 1100rwhp-ish. Custom cam is a must. I'm a fan of the Efi spyder intake with 90* elbow. I believe it'll hold a 90mm tb

TWIN TURBO!! Because bottles are for babies and superchargers blow

Whos turbo kit or headers are you using. I seen a 427 with twin 76s put down 1100 on 93. I believe boost was around 10 or 11.

For a 408w your gonna need AFR 225'S. The 205's are good for a n/a engine, but you want whats best for a turbo engine

If you go twins..looks at the 62's and then the 67's. The twins will be very responsive vs. the big single turbo.

Your cylinder head size needs to be as big as you can go for the power your wanting to achieve. Trust me..itll make your turbo more efficent

Also..by going twins, you'll be able to run two 3.5 downpipes and they'll bolt up directly to your existing h or x pipe.

Good luck.
