I have an 8.2 deck 369 with P38 heads and a Vic jr (may get changed to a super). I took a stock bottom end engine out that had a 60mm on it. The kit is an hp kit with a t4 flange. It is a dart block and I would like to turn it up pretty hard when I go to the track. I was looking at the precision 7675 ball bearing turbo because I obviously will need a bigger turbo. Do you guys think that will be a good fit for this combo? Car spends most of its life on the street so I would like to have something that is gonna spool kinda early like the 60 did. I have no clue what I can get out of this comb. Any insight on turbo size would be appreciated. How much do you guys think this can make on like 18lbs? Thanks.

It sounds like a pretty stout setupyou have there. The 7675 is a pretty good fit for your cubic inches. How many rpms are you planning on turning? You can give precision a call if you like . Or you can try matchbot

 

Thanks. I hope it works out as well as I’m hoping lol. I may call them I’m probly gonna turn it like 7k max. Thank you

 

Your not revving it to the moon so the 7675 should be pretty close

 

That is a stout combo. You didn't mention what cam, or trans, but I personally would go bigger, especially if going ball bearing.

 

Any suggestions? I want to stick with a t4 if I can. I don’t really want to cut the kit up because it’s all ceramic coated. Trans is a c4 and it has the bigger forced induction anderson cam in it (can’t remember the numbers) but I think I’m gonna have a custom one ground before it goes back in the car. Hoping this is gonna be the last time I tear the drivetrain apart for a few years so I wanna do it right lol.

 

You'll want to spec cam, and turbo together. I'm not a huge fan of Precision stuff as they share very little info so a call to them is the best way to go. I would personally go with some variant of a S480 but then you lose the ball bearing center, and they're physically larger. Call Jose at Forced Inductions if you're interested in something other than Precision.
