whats the stock turbo size and what is the best after market turbo and why

 

omg. Search.

KO4.
twin scroll.
and best aftermarket turbo is still being worked out.

 

I dont think there will be a good aftermarket turbo, to many people having tuning issues and such... Something small llike the 16G or a GT2861.. At least until more tuning codes are cracked and more fuel can be found to work...

 

there is no tuning issue really. need more fuel...

 

On DSM's an evo3 big16g ... 40-42lb/min (usually more realisticly 38-39 on most cars) is about where she tops out. Seems like a couple people on this site are saying they're pulling 37 out of their K04's right now. Point being, not sure I'd bother putting an MHI turbo on the car unless it was a 20G Not that the 16g isn't a great turbo, but why swap one small snail for another?

 

what about the S20G turbo that hahn is supposed to come out with? as for fuel , are there any larger injectors for the SS/TC?

 

Apparently its not the injectors themselves but the pulse width or something like that.

 

GT2871

And the turbo is fine.... for most on here its more than enough!

It's the pulse width.... and pressure is our issue!

 

i know that hahns S20G takes upto 500HP. As for the injectors, is there a website that has them for our cars or is an item that is not yet out. im pretty sure we cant use the SS/SC ones since that seems like an obvious.

 

I know the ko4 is the turbo for the ss/tc, but I cant find what mm it is anywhere.

 

just buy a gt35R, they bolt right up

 

There aren't any injectors for our cars, but in the future we might get fuel pressure control from hptuners which will give use more fuel to play with.
