one big turbo(60mm GN) or twin smaller turbos(t04)?

pros and cons in performance, not worried about fabrication. I only want to run 6-8 lbs boost. thanks

 

twins will give you more low end punch and blow your tires away.

A single will take up less space. With a V8, you are not going to experience any noticable lag since there are 8 cylinder feeding it.

Id say 60mm since it gives you more room to change plugs and what not under the hood.

Good luck.

 

A stock GN turbo is not 60mm

A stock GN turbo is not a T4 either

a single 60mm turbo will flow enough air for about 600hp maxed out at high boost (20-25psi)

 

Does anyone know what numerical sizes say 88mm, or 60mm translates to? For instance, what mm size is a T-3, or T04? Anyone know?

Thanks,

 

the numbers "88mm" and "60mm"......denote the size of the compressor wheel in the turbo. It is also the inducer (short diameter of the wheel) and not the exducer diameter (long diameter)

T-3, T-4 turbos are 'styles' of turbos. They can have different wheels in them to suit different applications

 

So what size are the stock gn's?

 

I heard the GN/TTA came with t3 turbos from the factory, but I could be wrong...

The larger turbos are denoted by size as their decription - T66 = 66mm, T72 = 72mm... There are a lot of different blade styles, blade pitches, and compressor housings to choose from. There is no generic T72 turbo.

I think that there are a few 60mm turbos available, but research before buying please.

 

yeah it's a t3 but i'm looking for specs in the openings and the wheels. for both exhaust and intake.
