So what do you guys think?

Frankenstien K04's (FT) or basically GT2554's (Tial)

No bottem end build and probably a stage 3 minus tune (still want to get SOME mpg.

Get the Tial 605 setup, the FrankenTurbo stuff is over priced Chinese turbos that's been marked up 300%. You'll get better mpg with the 605 cause you won't be in boost all the time. The FT is nothing more then a K04 with better low en and less top end. Plus the 605 turbos will give you plenty of room to grow in the future..

Thanks brother.
I appreciate it big time.
You bring up an excellent point.

Would I need to upgrade to Forged DV's or could I run 710N's?

Better low end, and less top end? They flow nearly as much as RS6's which last time I checked is MORE than a KO4

twv5004

I can second that! They flow more then k04s and spool like a k03.....just installed a pair 2 weeks ago and I have to say their build quality is up to par IMO

Having had both, and K04's as well, you can throw out the MPG factor since that is going to be a function of where and how you drive. Very little else in your post gives any indication of what you're looking to get from the car, aside from the 3- tune. Are you really thinking about installing 605's and trying to run them with stock fueling?

The FT is close enough to the K04 in performance that the pages worth of results for K04 cars will give you an idea of how the FT's will perform. There's also a pretty good amount of info floating around on 605's that should help you to see how they've performed on different cars. This should come as no surprise, the car responds differently with these two turbochargers, you need to determine what you want from the car and find the turbo that matches it.

Disregard the input from coldair, the FT's haven't been in play long enough to have a definitive track record. That being the case, if you have any reservations about possible longevity issues you may want to stick with the BW K04's or 605's.

The 710N's with the 605's are fine.

I'm saying don't get the FT and get either K04 turbos or 605 turbos. The turbine side of the ft is like that of a K04, yea the Ft turbos has a compressor wheel that will flow like the rs6 but means very little with that small turbine side, we've seen this many times were people upgraded there K04 turbos with rs6 comp wheels and gained really nothing. Rs6 turbos have produced near 500whp, K04 or ft turbos 380-420whp mated out depending on your parts and build.

The Frankenturbo's have been available for such a short time I don't think it's fair to judge what they're capable of just yet. Aside from VAST, whom seem to be mainly interested in sales volume versus dialed in tunes, I haven't seen results from the other main tuners. Not saying that in the end they won't prove to just be a cheaper alternative to K04's, but I think it is too early to tell. The early K04 cars did not make anywhere near what some recent K04 setups are making, a little time to understand the turbo's capabilities has led to some decent improvements in the past.

coldair

Then why don't they make RS6 power or even close? Like I said yes the compressor wheel flows that of the RS6 but matched to the small K04 turbine side it means nothing. You can't have it both ways "spool like a k03 but top end like rs6" there's enough data out there now to see there comparable more to the RS4 not the RS6 or close. AZ has side by side comparisons and logs and there near the same when paired to the same tune and hardware.

Lets say you managed to fit a GT28 compressor wheel in a K04 or FT turbo do you think those turbos will make near 800chp? Yea the compressor wheel flows 38lbs but the exhaust side is the limiting factor.

Remember all the cars that had RS6 comp wheels in there PJK04 turbos and made no noticeable power, well this is the exact same thing. It's like taking a K03 and putting a K04 compressor wheel and saying the turbo flows the same as a K04.
