cpt61 vs pt6765

[grocerygetter]

whatchya think?

I've got a Cotton's bb 61, .63 AR, P-trim, S-hat. You think it would be worth going to the new billet PT 6765, ball bearing, .63...I'm running about 25psi currently...wanna go faster...I wanna keep the pat's 3200 LU converter too.
This new turbo or heads...which would be a bigger gain. either way is about 2K.

Judging by your sig I don't think you have the other supporting mods... You are probably topped out with your inj's at the mininum...

Yes it would be a big difference, I would get the heads first!

you dont need a turbo you need to get some hi imp 79lbs injectors and tt chip about 499.00 and save some cash turn the boost up you sould go in th 10,s easy.

I have a tt alky chip. I think I'll probably have to bump the fuel a tad in the chip but so far so good at 25psi.

You havent stated your goals. We cant analyze your performance based on your sig. Heads will make way more power than a turbo at this point without a doubt if you can fuel it. You will be in the 10's at 25psi with a set of heads and decent traction if the tune is on. If your not locking the converter at WOT then you are sacrificing a lot of mph. I dount the converter will last being locked at the 10 sec level.

You can easily see there isn't enough injector for that turbo mentioned...

Yeah. Without alky he will run out around 124-125mph on a strong tune. Easily could happen with either turbo and the correct tune and supporting parts

yeah...I know the alky makes the difference. Bigger turbo meaning bigger injectors...better heads meaning bigger injectors...that's fine. Makes sense.
Goals...well...I just want more. LOL...it's like a bad habit. You know.
I've told myself over and over that the first time I lift a head that I'm buying new ones. I may just keep that as target. I'm going to the track with some friends on the 14th. We'll see then I guess. We have a 1000ft track local...I'd like to see mid 9s on a semi-hard launch off the brake (7-8psi). We'll see.
