turbo chioce for buick v6 stroker

[NOT 38]

hey guys im looking at getting rid of my blower and opting for a turbo (finally)

Now, i have a fully built low comp come racing stroker. and i want to make some decent power. its capable of handling 20 to 25psi.
i have been looking at either a t51, GT45 or T04Z.
i dont want too much lag but driveability isnt a issue its already a pig.
what do u recomend turbo wizzards ?

4.2L and 20+psi? the GT3582 aka GT3540 turbine wheel will probably choke it.. be nice and responsive with a .8 or even 1.0 A/R turbine housing though.

Best thing to do is work out the engines airflow and look at the compressor maps of those turbos (T51, GT42 or TO4Z).. talk to some Turbo reconditioners..

My 2cents - any off those will work, probably the TO4Z with a .8-1.0 A/R turbine housing. It will be laggy though.. use good tubular headers - Commotion makes very good ones "Boost Obsession" search this site.

lol i dont see how a 35/40 will choke it think about the ford theyre are 4lt running with the smaller .82 housing and making 300rwkw +

Ed Sleeper on here runs a proper 35/40 with a 1.06 rear housing and bigger front on about 4.1lt capacityand thats making 500rwhpo and running low 11's with 2 sec 60ft. that only about 14-16psi (varies a bit) its also revvingn to 6500rpm with dropping off or choking the engine not sure what the stroker goes too.

35/40 are so popular as they are very versitile turbo great response even on 3lt and good outright power. If you got the cash defenitly go ball bearing and the X version with the billet front wheel look at a bigger front housing option too

GT35r might work but if your going to the trouble of buying a new turbo you might as well pay the few hundred extra and get a decent sized one you will make more power on the same boost. I would go GT4094 for response or a GT4294 for peak power.

this car has a GT4094 on a stroked ecotec. Apparently the response is good but have not seen it in person.

replace #'s with street_commodores (minus the "_")

GT4088?

Must admit to knowing nothing about turbo's

 

[GMMAD]

a better question is how much power do you want to make?
it auto or manual?
what driving do you so in it?

 

[NOT 38]

looking to make between 450 and 500 rwhp.
its auto (th700). and its street driven.

considered twin turbo instead, less lag more top end power if u choose sequential twin turbo setup
