Possibly about to pick up a 93VR. The motor had a compression test, and it looks good. But the car has 73k on it, so its only a matter of time. Just curious who has dealt with Pettit? Thinking about just gankin the motor while I have the money and having it sent in to Pettit for heavy duty 3mm seals and a streetport. Is Pettit still doing the quality work they used to?

Whats 'gankin'?

yes pettit still does top notch work, infact i had the chance to meet and bullshit with cam himself over the weekend at elkartlake and from what i can tell ya he is one hell of a nice guy and smarter then alot of people who claim they know how to rebuild a motor.

just dont do the 3 mil seals.



Not worth it!

I agree. https://www.nopistons.com/forums/pub...IR#>/blush.png

Probably a dumb question, but what the hell is the difference between the two? Advantages and disadvanteges of the 2mm and 3mm seals?

People use 3mm apex seals because they think it will improve engine reliability. I don't see any outstanding proof that they do. If you ping the engine it will break a 3mm apex seal just as fast as it will break a 2mm apex seal. I am sure there is a marginal difference in the tolerances but I gotta believe that having the maps tuned properly would be better insurance and a smarter way to spend your hard earned cash. Not to mention I have seen 2mm apex seals take 30 pounds of boost and not break so if that is the case why bother with 3mm apex seals? I would guess that the 3mm apex seals are pricey compared to the stock ones and you have to pay someone to machine the rotors to fit the larger seal. A lot of money for a small gain if you ask me.



Thats my opinion anyway.

The arguement is that a 2mm seal will break after the first ping and a 3mm seal can take up to 3 pings. That's at least what all the manufacturers of 3mm seals will argue. https://www.nopistons.com/forums/pub...IR#>/smile.png But the price differences really don't make 3mm seals worth it.

Oh, ok. Thanks Dave. I knew it had something to do with boost.

Ok well lets say this. Out of all the shops out there, who would you guys personally take you're FDs to for a rebuild and streetport?
