Biggest Turbo Possible

[turboz4life]

Hello,

What is currently the biggest turbo available to run with a 3400-3500 stall convertor? Ball bearing, billet wheel, 3 bolt or 4 bolt doesn't matter. Thanks in advance.

 

[GNBRETT]

whats ur combo. too much unlisted info

 

[bison]

What combo, torque converter, hp and e.t. goals. Not all converters are the same. A lot more to it than stall speed

 

[Quick6'n'-K.C.]

Big enough to blow it up thats for sure....

66 67 68 ? 70?

Street car with everything else done, or track car?

Personally bud, it all depends on what else you have done to the car.

Then again, you could do what I seem to do oh so often and just buy the biggest, baddest, newest street turbo you can get and then build ur car around it.....

I would strongly advise against that tho. Especially if ur married or ever wanna be....

Honestly, a 3500 stall converter could be all over the place as far as what turbo would mate to it.
IE: A 3500 PTC converter would have totally different characteristics, than let's say an old school Art Carr 9".

So the main question would be, how fast do you want to go?

Seeing that we currently have a Billet 71 HPQ that is fully capable of pushing a built TSM combo into the high 8's now. And bolt on real street cars running low 10's with a Billet 6765, it truely is a pick your poison type of question.

Here's my pics based on today's latest turbo technology.

Bone stock car with no mods except fuel system and exhaust mods. Wanting to replace his stock turbo and have a nice upgrade, Billet air cooled dual ball bearing 5857 turbo.



Bone stock motor with fuel system mods, stock or after market torque converter, intercooler and exhaust mods wanting mid to high 11's. Billet air cooled dual ball bearing 6262 turbo.



Bone stock motor with the same parts wanting mid to low 11's, Billet air cooled dual ball bearing 6265 turbo.



Stock bottom end with heads, intake, cam, intercooler, exhaust mods & fuel system mods wanting low 11's to mid 10's, Billet air cooled dual ball bearing 6765 turbo.



Build bottom end with all the above wanting low 10's, Billet air cooled dual ball bearing 6765 turbo.



Built stroker motor with all the above wanting low 10's to mid 9's, Billet air cooled dual ball bearing 67 HPQ turbo.



Built stroker motor with all the above wanting mid to low 9's in TSM legal trim,
Billet air cooled dual ball bearing 71 HPQ turbo.



From here, you get into T4 turbine housing equipped turbos. At least this is what I would do if I had one of those scenarios before me.
Hope some of this helps a little.

They change so fast, but i like the BB 6776H! Havent come close to max yet.

95% of the board members will never max that turbo out. No need to ever upgrade imo.

This sounds alot like something I would do. Motor will be a stroked 109 with all the goodies GN1s, 218ish hydraulic roller, 3.5 downpipe, alchy injection, will probably go with FAST XFI. Would like to be able to go with a built 200R4 to keep the car streetable. I have heard nothing but good things about the PTC converters so I will probably go with one of them. My goal is to run a 9 on pump gas and alchy. Hope this is enough information. Thanks.

More like 99%. They cant even max out a stock turbo never mind anything aftermarket. lol

Hope you have a really deep wallet:biggrin:. All very possible. Go 4 bolt and run the HPS turbine. Any compressor size 66-76 will get it done. If you go 3 bolt vs 4 bolt the cam selection and installed will be much more important. The 4 bolt will allow for less than optimal selection and installed location. Be sure to build around a stage 2 or TA block and forget the 109 unless you need it for class racing.
