if i turbocharged my 2.8 with a ko4, how much hp do you think i would be at?

dingster

Unless you go with 2 of those. They you're looking at big hp. By then you probably spent enough money to get a S4.

daKiDD

but i have a 2.8 right now, and arent ko4s about 850 each right?

AFourSheezy

but why turbocharge a 2.8 when you can supercharge it with pes's kit? Never heard of anyone turbocharging a 2.8 w/ a K04 so you might be the first one =)

daKiDD

but how much would that cost. Isnt the kit like 5000 dollars to get 290? If each of the ko4 are only 850, then u can get it finished for a lot less, and with a bigger engine, should beat an s4 right?

The bare turbos are about $800 each, but there is no appropriate manifold, ECU, or exhaust, or anything else that has been tooled for a 2.8/K04 application. If you've got 20K to throw down, you can think about fabrication.

In any case, a 1/10th litre displacement differential would not net any significant power gain, even if all the other factors were equal, which they aren't.

i can get it installed for a really good prrice with a custom manifold. So that owould be ok. Where would i get these ko4s for about 800?

Skydive@AI

Install it for a "really good price" didn't know what they were saying. You'd need custom intake and exhaust manifolds, a completely custom ECU, an intercooler or two, plumbing for all that, and possibly some internals. (And, I'm sure I'm missing a piece or two.)

As far as pricing goes, there are group buys from time to time, or you could find the guy who routinely sells new ones on eBay or the classifieds here. There's always Bramall turbo.

...but you're wasting your time. Dual K04s on a 2.8 is going to cost you a pretty large chunk of change, and certainly a LOT more than a PES kit.

WYSIWYG

and i think its about time i remind you. so, am i going to get it?

A twin turbo K04 kit would cost more than 5k. You're going to need new software, new manifolds, turbos, FMIC, etc etc.... all this is custom work which would cost more than 5k. The S4 is a 2.7T with twin K03's and is pushing 250hp (and thats now wheel hp)... I think the pes supercharger is the best way to go for the 2.8
