Default Guys with 500whp+ w/ T56 come on in

Whats up everyone, have a few questions that my buddy asked for some info on. He has a 98 Z28 with 500whp, and currently has a blown T56. We were wondering what kind of manual trans set-up you guys would recommend for this much power. Any info at all would be greatly appreciated.

If he does alot of racing and not much street driving he can proshift the T56. There are a few upgrades than can be made in a rebuild like hardened shafts, steel shift fork and the carbon material blocker rings.

he pretty much daily drives it, with an exception on a few nice days were he drives his bike, so do you guys think something like that would be tolerable in a DD?

More than likely he blew the syncro's but we use a stock tranny with upgraded syncro's shift fork for our 800hp/800tq car without issues.

The T56 is a great racing transmission that can be built to withstand a great amount of power. I built mine up and it can now withstand over 500 rear wheel horsepower. There are multiple websites, sponsors and shops that can prep your friends transmission for him.

i'm gonna take a shot in the dark and say that the trans is either jammed in a gear, or that it is grinding gears.

neither of the above are a result of abuse from high horsepower, rather abuse from the driver.

rebuild it with the stock upgraded components and practice safe shifting

well we figured it wouldnt be to bad either once we got it apart. it would grind a bit into third, and would always pop out of 5th and reverse, so we figured only a couple syncros would have to be replaced, turns out all the syncros and gears were pretty much fried along with his clutch. he was having some problems with the trans ever since he bought the car when it was stock. then added a TR224, all bolt ons, 12-bolt and sticky tires, and the trans got worse. he then hit it with a 125 shot and a good tune. so the trans has had some abuse.

What does "Proshifted" mean?
Judging from your sig pic, whatever it is, it must work!

Proshifted is normally straight cut gears and they pull the over drives out as well. The car trans becomes a T56 four speed car, and the straight cut gears often eliminate the need to use a clutch for shifting as well.

Probably a simple rebuild would suffice for a 500+ setup. Some of the stuff that these guys mentioned above is a great start.

i think is is going to go with package #3B from T56rebuilds.com
Seems like it would be good for that kind of power.
What do you guys think?

new hardened shift forks, what ever else you can get out of a viper tranny and kevlar stuff is great too.
