I am working on picking a turbo for my stock cube truck manifold build. How much power are you guys making with this unit? What is it's power potential on stock cubes? Thanks guys

I went 136 mph on a TC76 (same power pretty much) in my heavy *** GTO.

Mine trapped 130, with the eBay kit in my fat pig. I think that was on 12psi.

Impressive! My friend's TA traps around the same with about 100 more wheel hp than you with some bullseye T6 turbo on a 347. What is your race weight? More info on your setup?

Honestly you're better of with the 76gts if you have a decently modded n/a motor. For a stock engine the tc76 works great. With better heads, intake and cam the 76GTS spools the same and makes more power over the tc turbos.

I wouldn't say spool is the same. It's close, but the TC definitely spools quicker.

I did 675whp,15psi, through a 9 inch and auto. 3800lbs went 133mph. Awesome turbo imo.

Mines for sale too!! Barely used $750 shipped!!

574 at 10 lbs, 9 inch amd a 3500 stall.

Im dieing to turn the boost up with my new forged motor.

I plan on a forged motor (rods, pistons) a decently bumpy FI cam and possibly TFS 220 heads if i dont cheap chooch out and go with 317s. Would it be in my best interest to go with a PT 76gts? I am open to any and all suggestions. A friend who build a pretty fast turbo car even suggested i go with a PT88 (t4, .96 a/r) but i think i may run into fitment issues as my KYTP kit is built around a TC78.

i did and still do want a 76gts. they will definitely support more. i got a great deal on my TC which is why i have it now, and based on what its doing now at 10#s im 100% confident it will meet my goals (9.90's 6speed)

im 110% happy with my TC76, but if you have the extra cash i would go with the 76gts

I thought the GTS was not sold anymore and they replaced it with the another unit 7675CEA(billet) or 7675HPHS?

Tally TransAm

iTrader: (17)

not sure, i think your correct though

Nitroused383

7675 is just the new numbering system Precision uses, it's still the same 76GTS. 83mm inducer and 75mm exducer on the turbine wheel. NicD has gone 151 mph on the 76GTS with a 346 at 3400lbs. You won't see a TC76-78 do that, the precision unit is good for atleast 125 rwhp. Several people have made over 900rwhp with the 76GTS. You honestly cannot buy a better turbo for it's size. It has a bigger turbine wheel that flows more and a slightly larger more efficient compressor cover.

I do all my own tuning and have tons of logs to show you the spool comparison on my setup. They both hit the wastegate at 2600-2800 rpm in 4th gear.

what is the physical size difference between the tc78 and the 76gts? any side by side pics? inlet and outlets the same size?
