'69 Chevelle twin turbo

[Csx254]

Ok, I'm planning on doing a turbo 350 in my chevelle in the next year or so. My question is, what size turbo's do I need? I was going to go with two Hybrid t3/t4 with the 57 trim stage 3 exhaust, but I was wondering if that would flow enough? I know little about turbo sizes, an how to know what flows with what, so any info on this would really help. Bigger or not?????

Im sure you could run something like twin sc6152's and have some real fun.

www.turbomustangs.com There is a good chevy section.

I'd go minimum .63 with a higher stage housing. 350=5.9L. A hot 2.5L Spools up a .63 nooo problem, with an extra .5L to spool it, you'll be running out of traction left and right. There are turbine maps, but nobody looks at them... this is a shame.

350 is a 5.7L. 360ci is a 5.9L.

What kind of spool up time do you see with the Twin T66's? Where could I get my hands on a set of those. I have a single Mack truck turbo sitting in my garage, but I would like to go with twin setup.
Looking at mainly racing, but some street time too.

Is that the red camaro that really needs some suspension work so he can actually launch the car?

Yeah, Im pretty sure he also blew the crap out of that motor. aluminum block FTL

Im sure he is getting a cast iron block.....I think someone said he was rebuilding.
I talked to him once at the track, he is pretty nice.

I don't have any feedback on the spool up yet the motor is still on the stand waiting to go on the dyno soon enough. BUT I supsect it will NOT be an issue since the motor should make well over 500hp on its own.

What about two t04b turbos? I did some price checks on turbonetics website and they want $1600 per t66 turbo.....a little outta my range.
