I know someone selling a K27-7006 turbo used with 3000miles on it. I was wondering is this something that can be bolted into place without mods or is additional work required? Also what gain would there be on a 3.6 turbo if nothing else was done?

Thanks

Your car is fitted with a K27 from the factory. The 7006 is not really an upgrade. Something like the highflow would be, but not the 7006.

I was under the impression the car was fitted with a K27-7200. I was told the K27-7006 was a better turbo that spooled up faster and was a higher flow turbo. Is this incorrect? The asking price is $400.00. Is it worth purchasing as a spare?

You do have the 7200, however the 7006 does NOT spool faster and will shift the curve up a bit. Honestly, unless you are going to do other mods keep what you have. The 7006 still suffers from the lack of air up top. I look at it as the expense and the gain you get. For 400.00 and a used turbo the risk is a bad turbo, and a less than 10HP difference if that may not be worth the expense to swap out. You would also want to have the turbo gone through if you buy a used one. At the end of the day the 7200 is a fine turbo. Now the HF is a different story

Stephen,

Thanks for the advice.

I wasn't realy looking but since it was available I figured I should check it out. I have no idea of what the value of a used turbo is, $400.00 sounded cheap. I know the person who is selling it and he guarantees me it is fine. He said any issues and he would refund my money.

Now you have my curiosity about this HF turbo.

Any more info you care to share? What should I expect to pay and what benifit would I gain from it? I am not interested in dropping the engine and replacing any internals but if there is any benifit to a simple turbo swap, what the heck.

Thanks

Anthony,
My pleasure.

The HF is a modern compressor wheel unlike that of the K29 and really even that of the 7200. The 7006 is in the same boat. The new compressor wheels are 16 vein and the technology maximizes compression to create larger volumes of air without loosing low end response. The K27 is a 12 vein setup. Finally technology has blessed us with the ability to build a KKK/BG platform and spool like a k27 but blow harder than a k29. Unlike the standard K27 series the HP will not loose efficiently when running upper RPM ranges at levels of 1 bar or higher. Traditionally the K27 will fight to maintain boost in this area at these levels. The HF just laughs and moves on. That is the benefit of technology .

Progress!!

You have to love it.

What, if any benefit is there in just replacing the K27 with this HF unit? Or does the extra volume of air only work as a package with cams and improved fuel distribution etc?

Is there a down side to this extra blowing power?

Is this something you would recommend, and is it something you supply?

Sorry for all the questions. I generally understand how the turbo system operates however I am still unclear on what changes give you the most benefit without ripping apart a perfectly good engine.

Thanks

While I dont know what the value is without other mods, man it is awesome with a few! Worth EVERY penny.

If you don't mind me asking, what Mods did you perform and what benefits did you feel you gained.

I hate opening a perfect 30k mile engine if I don't need to. I figured I will wait a while and see.

I wouldn't mind any possible gains. I already have the B&B headers and 1 bar spring. I was thinking about going with a Tial waste gate with .8 and .2 bar springs and dropping the cats for a fabspeed muffler and tips. Possibly a complete Fabspeed exhaust. I figure I will eventually go the complete route but would prefer to leave the internals alone for now. If there is any gain with the HF turbo without doing the rest then I will do it for now and have that upgrade behind me when I get to it.

My problem is I don't know enough about this turbo (including cost and fit along with additional heat issues). If you guys could shed more light on the particulars of whether or not I may see any benefit without breaking down the engine it would be appreciated.

Cobalt,
If you are looking for a little more power the HF will provide that and certainly while cams help it is not a must. The turbo moves more air. By moving more air at a given point compared to the previous turbo you will realize a gain.

If you need more then yes, I do recommend it. That is a personal question that only you can answer. It is also something that we do sell.
