Hi!
I have 1.5 dohc 16 valves turbo setup for my ACCENT GT!Now i putt low compression 7.5.1 piston forged rod etc etc!Now i want the best turbo for my setup i will run 15 psi in first and 18-22 psi on track!!!I see GT28T ball bearing turbo
.60 A/R Exhaust
.63 Compressor
Dual Ball Bearings
Ceramic Ball Bearings
.67T Compressor Wheel Capable of .59 Lb/MIN Airflow
Boost at 2700 - 3500
Oil and Water Cooled
Internal Wastegate @ 12 - 16 Psi
HP Rating UP TO 500+

It too big for my setup?well give me your answer sorry i speak french

Re: Best turbo????
 

Holy ----, 7.5:1 compression? It'll be a dog out of boost.

This piston!75.5mm 7.5.1 you know low compression piston for hyundai it not easy to find well life is life :6

Re: Best turbo????
 

Yeah fuuuck O0

Re: Best turbo????
 

I dont ask about PISTON i ask about turbo :7

Re: Best turbo????
 

With that low of compression you will probly spool up later than that. But I'm not sure because a ball bearing turbo will spool up quicker.
It wll be great top end, but REALLY slow when not in boost. GREAT track car, not a very good street car. In my opinoin.

What are you using for fuel management?

Re: Best turbo????
 

Compression doesn't have much effect on spool. Displacement, as per usual, is king dick.

Re: Best turbo????
 

Haha...king dick...i like that. +1 on displacement. As the old v8 adage goes...there's no replacement for displacement ;)

Re: Best turbo????
 

I guess I don't get it then...arn't you moving less air/exhaust when you lower comrpession?
Well, the more I think about it, the more it makes sense. You really aren't moving that much less unless you went from like 12:1 to 7:1.
Not really a whole lot of differece in them piston tops. Never mind me I'm just thinking and typing out loud. I'll go away now.

Re: Best turbo????
 

No...I would think how much air you move is based on the cylinder size, the compression level is just how much it's squeezed :P Possibly the velocity will be higher on the more compressed air, but compression wouldn't change how much air can fit into the cyl, but that's just some crap I'm guessing.
