Default Ding!!!!

We have a winner!

Ideal turbo, for me:

Comes on about 3k, but under that, no boost. Why? Because, then, if I drive it like a granny, I can stay out of boost always, and keep the MPG reasonable.

Comes on hard at 3k, then goes all the way to about 6.5-6.9k, where it drops off. If I need to, I can keep the revs up there for being on-boost. And when it's on-boost, I want it on HARD.

This turbo will work with the RS2 EM, and the RS2 injectors, but the stock MAF and fuel pump.

And it has to be a journal-bearing turbo, for reliability and longevity.

Default Keeps the oil from coking in the bearing.

Coked oil = no lube, and that's bad for turbo life.

but this only happens when you do not care properly about turbo right?

Default No. Taking care of the turbo is a good thing...

...regardless of cooling. But coking can happen quickly if your turbo is really hot, and you don't give it quite enough cooldown/spindown.

Water cooling gives you a much bigger margin.

Default which water cooled turbo would be a good alternative to K27 then?

let's say we are looking for everyday use
not so big lag and at least 350HP

RS2 setup?

Default Yeah, that's about right. As compared to a K27.

I'm not a fan of ball-bearing turbos, though. I think the reliability and longevity of a journal-bearing turbo rules, IMO.

YMMV, of course.

Default Seen it used with custom IA programing and a front mount IC

Amazingly fast!

I always see people saying this... but never really hear about failures.. You have one fail?
