Been wanting to build a twin turbo 350 small block I got forged crank pistons rods arp bolts / studs stock cast heads ported to 202''s have a 9.28 static compression ratio with 75cc chambers I bought 2 50mm wastegate's and a 50mm bov was going to go with 2 gt45's from ebay but now thinking about doing a godspeed gt35 ( http://www.godspeedperformance.com/gt35-turbo-charger-63ar-rev9power-tc-007-p-247006.html ) to spool a godspeed t88 ( http://www.godspeedperformance.com/...o-charger-05ar-rev9power-tc-047-p-530421.html ) I am thinking about going with open chambered aluminum heads to stay close to the cr I already have, Its going to be in a little chevy luv for strip only use with rare street use to car meets my questions are:

Would the turbo's I'm looking at be good on throttle response time(little to no lag)?

Would/could the gt35 start choking off the t88?

If anyone could give some advice I would greatly appreciate it,
Thank you!

 

You missed the boat by like a lot for compounds that t88 is basically the same as a s475 t4 or a gt4202 garrett it would make a great single by itself . The twin gt45 would more than own that t88 . Are you looking for outlandish boost like 45+psi ? I'm not following the reason why you need compound turbo sbc. Compound turbo are used to keep the compressor in the map by creating a higher pressure atmosphere for the secondary or hi pressure turbo like displacement or rpm limited application looking for extreme power . Ie diesels and import 4 bangers. To make 1000 hp Honda you need big turbo at big pressure ratio. It's super laggy and hard to keep the compressor in the map for efficient boost . So we make 2 to 1 with a charger taking atmosphere from 14.7 to 29.4 psi then we do it again taking 29.4 to 58.8 this gives us 4 to 1 pressure ratio with out taxing the turbo so much and allows for a more drivable combo. On a combo like yours you would be looking at a pair of compounds and making 2000 + hp . Ie twin compounds. I'd say stick to the twin gt45 or go with a single like s480 .

 

a pair of the cheapie gt35'S would work pretty good
