first of all i have heard that the LS 6 speeds use a different input shaft and won't work on a L98.
plus i also am looking into add more hp into my car becasue i know that the t-56 is only rated for around 400 hp and i would like to break that soon

so with all that what would be the best for my car which is a 1991 z28 with the 5.7 l98???

 

anybody??

 

you are right, an ls1 t56 has a different bolt pattern, just get an lt1 4th gen t56

 

and the lt1 t-56 which is out of a 93 to 97 f boby will be the best fit for my car

and what is the rated hp on that transmission?/

 

A t-56 can handle more than 400hp. Hell mine held 600rwhp then i had it build cuz I had so much downtime waiting on pistions and new turbos. And so far we took it to the 900rwhp range. car has a 12bolt with 3.42posi and a clutch like a light-switch. I killed to clutches in the fist 90days I got the car new. Cuz I never drove a stick. But the trans held even with me grinding gears. And even when I was forcing into gears that where not there. No bent forks?

 

well thats makes better to by becasue i was hearing that it goes up to 400hp but if your help to 600 then what i am going to do should hold up to cause i am trying to climb up to a little over 400 and its a good thing i already know how to drive a stick

 

Yeah and my other two buddies both twin turbo cars had t-56 one 560-660rwhp and the other 890rwhp. however we killed 10bolts once a week! In fact i think we each killed 2-3 before DTS was nice and gave use the 12bolts.

 

yea thats pretty sick but i am not running that much hp so i should be good will the rear end i have right now but if anything happens to it it looks like i am going to also have to invest in a better one

 

so has anybody bought a t-56 from a junkyard and if so how much did you pay for it?
