CPT-66BB vs PT67BB

[cuda6pak]

Looking to pick up a bigger turbo to go along with my Cottons FMIC and was planning on going with a PT67BB but have been reading a bit and seeing some good reviews with the CPT-66BB.

What are the main differences between these two turbos? They also show an optional F1 compressor wheel. Whats the advantage with that? I assume stock cube guys run the .63 wheel?

I'm just looking to go mid-high 10's or so (street/strip) and know both will accomplish my goals. Running a built motor/tranny with an Art Carr 3000 lockup and will be picking up some 60lb inj and swapping my old style SMC with razors dual nozzle kit.

there is no .63 wheel.... i think you are referring to the A/R of the exhaust hsg... and .63 would be cool for a street/strip car. i think the F1 wheel is turbonetics version of the GTQ wheel. PT67BB would be a Garrett/Precision unit which is Dual ball bearing and would require water cooling. the Turbonetics is a single ceramic ball bearing on the compressor side and journal on the exhaust and does not require water cooling but has an option. Turbonetics has a 66mm compressor wheel - Precision has a 67mm.... both would get you in the 10s WITH THE RIGHT COMBO - Turbonetics has a 1yr NO QUESTIONS guarantee... hth

also.... food for thought... Precision is releasing a BILLET 67 wheel, which IMO, would be KING OF THE STREET in ball bearing form

Thanks for the quick reply. Yeah I meant .63 exhaust housing, sorry about that

Whats the pricing on the precision billet wheeled 67bb? $1200 is hard to beat for the CPT66BB...

Ive ran a 66 turbo from a mild 4.1 motor thru a stock 3.8, up to a heads and cam 3.8 motor.

It all depends on your heads.

Make sure that 66bb is really a 66mm compressor wheel, turbonetics numbers are jacked up .... why else would you get a 66 bb for so much cheaper?


How much does it flow compared to everything else out there?

But then again, what are your goals?

The F1 replaces the 76 trim or p-trim. The S trim is the largest wheel you can get in a 3 bolt from t-netics. The s trim could go 9's with iron heads if pushed. I went 10.29 with a 3-4 lb foot brake launch with it. The difference between the 66 p trim and the 67 p trim is 1mm on the compressor side. Exhaust is the same. T-netics BB turbos dont require water lines and install easier than Precisions BB units. Running either of these hard will require a good converter or it will eat up a lot of mph
