to all who want to know if its bolt on,it is,if your talking about the downpipe,exhaust flange,oil and water fittiment.all you need to modify is;j-boot-since the inlet is 2.75",shorter temp sensor-because of the larger compressor,youll also need to bend the water line(hard pipe) to clear the housing,and youll need the proper chips to run the full potential of the turbo.danno has a dyno chart(search it) of a k27/8 making 370rwhp,with minor mods @20psi.im sure you can get 400rwhp out of a k27/8 7200.many think ill be making 300rwhp or even more.im thinking 285rwhp.my setup:k27/8 7200,test pipe,3" catback exhaust,LBE,3bar fpr,modded wastegate, and guru chips.all on stock afm,the reason being im going to a tec3 later on this year(hopefully).

as far as the best priced k27s,goto EBAY alot of k27s lately but theyre for the 930 but with a few mods theyll fit.

Here is the response I got back from Turbo Performance:

Does anyone know anything about the T04B? Is it comparable to K27/6? I hear that it out performs the K27/6 and it is cheap!

mike1982, i posted my dyno runs with a k27/8 a few weeks ago, do a search for them. i do have vitesse chips and pb which makes the tuning easier.

What's the turbine outlet size on the #6 and #8?

What needs to be modded beyond the usual K27 stuff?

Turboperformance rebuilt my k26/8 to a k27/8 for 600$ shipping included. I paid an extra 20$ for the clipped wheels which I now think may not have been a worth while investment.

They did take a VERY long time to get it to me though.

There are zero clearance issues with a K27 compressor (of any flavor) and the stock intake manifold. And... it's not even close.... clears by a mile.

I would not clip any of the compressor wheels on a K27. Bad mistake. I'm not going to take the time to articulate why (search the archives)...

>>>danno has a dyno chart(search it) of a k27/8 making 370rwhp,with minor mods @20psi.<<<

Correction... This is not a stock engine. And, Danno didn't do any of the work on the engine. That engine has considerable cylinder head work as well as a larger cam (neither of which Danno had anything to do with).

Don't think that your car will perform the same.. because it won't.

But.. you can expect around 335rwhp to 345rwhp on a stock engine with a K27/6 at 20psi with the typical bolt-ons.

Lastly... on a stock engine with the usual bolt-on stuff... a K27/6 is a far better setup for the street than a K27/8.

Good to have you back Tony i've been wondering where you went....

TonyG

With respect to "who's doing the conversions..."

I have used Turbo Bob at www.turbo-performance.com for about 15 years now. The guy has been rebuilding turbos since most of you were in grade school (or before). He knows what's up. And... he's honest, does what he says, and will go the extra mile for you.

He goes way way back....

I'm not sure how his prices compare to anybody elses... but he is a very fair person. And I couldn't imagine that his prices would be out of line compared to anybody elses.

TonyG

PS-> Not trying to offend anyone.. just making a point that he's got many many years of experience going way back...

Yo

Been heavily involved in turbo charging 996tt's lately. Basically doing all the stuff I do (have done) with respect to development to the 951.... but just with a LOT more power :-)

We're running about 650rwhp on the average bolt on car.

"We're running about 650rwhp on the average bolt on car."

Tony, could you kindly respond to a "3' exhaust" thread, i may have mixed up a few things in there ...........

david fracolli

Tony, I sent an e-mail to Turbo Bob and actually he quoted me the best price for converting a k26 to a k27 so I would have to say he is definately in line with everyone else.

slim_boy_fat

Ye right...

TonyG

Sorry... your're correct. I misposted.

It's not RWHP, but Bhp.

RWHP with nothing more than stage 1 turbos and an ecu upgrade (stock exhaust with stock cats, stock airbox etc..) make about 510RWHP at a 25% drivetrain loss at 1.2 bar boost. (which is the correct driveline losses with the 996tt AWD setup).

That equates to 680 crank hp.

With air inlet mods/ air box mods, headers, bigger cats or no cats.. the number get much bigger.

Tony- good to see you're still around... I, too, saw the dyno's on Danno's K27#8's & was very impressed- Cervelli used to always recommend #8's too- i'm planning to go that route, but, I DO respect your opinion & vast amounts of expereince- If I were running short tracks I'd go w/the #6- Most of the high-speed acceleration I do is at higher speeds, &, I've gotten rather used to the K26#8- that doesn't have REAL boost until 3500 & peak TQ @ 4000- the K27#8 will be much lower anyway, even if not as low as the K26- w/wastegate mods, chips, higher boost (I'm looking at ~17psi when I'm done) some headwork, exhaust, etc, I'm expecting 3000-3500 & MUCH MORE at ~2800 than I have all day right now, so, I'd be very happy, &, happy w/the overall HP gain, which, most people say is more like 20-25 more, at peak, than the #6- not 100% sure about this, so, if I'm wrong here, please let me know... I'm also going to do some crank work- mild lightening & get it balanced, etc- same w/the Flywheel- not planning to take much off either, but, a tiny bit will make it nice- a local 951 had a lot of weight taken from both- incredible at low RPM's, but, sucks up top- i think it's mostly b/c he screwed w/his relia-boost that he bought from Danno & never fixed it right... he just let it go w/out calling Danno for advice- he'll get to it eventually I guess....

Also- do you know much about Turbonetics? I talked w/Albert at Broadfoot the other day- trying to decide what to do w/my engine- my mech wants me to find a low mileage one & trade it out, but, I'm looking into rebuilding mine, using my head (w/a little more work- its P&P & shaved right now) & then going to bolt-ons. I'm going to PM you later w/a few questions.... But, was the block you were selling back when I bought the C2 wheel's from you a year ago, the 3.0L one, was it a Broadfoot? BTW- you should see your wheels now- they are PERFECT- had a friend refinish them for cheap & they looked BRAND-NEW!

thanks....
