Yeah, I wanted to learn stick so I bought my buddies old T56 6 Speed out of a 2001 Camaro. So I put in the whole LS setup in and taught myself. Was not the easiest thing when you have a .650 lift cam and a racing clutch. Yeah I spun a rod bearing, totally my fault. The motor was a junkyard POS with 100K miles. I would bang it off the limiter at 6500 all the time, every shift.
Im gonna take it to work and rebuild it with forged rods + pistons. My goal for compression is around 9.0. And im staying 6.0, and not stroking it because I believe that LS strokers have one fatal flaw. The factory block's cylinders are too short for a 4" stroke. The skirt of the piston hangs out the end, and it rocks back and forth, wearing it down. Yeah I plan on running no bigger than a 75MM so I can use it on the street. Monster turbo needs time to spool.
Hey now, that's the only way to drive. I was doing that and 5500RPM twostep launches on my 2015 EVO X (703hp on E98 / 546HP pump 92). Rev limit shifts at 8800RPM all day, every day. It makes me miss having a fast car but getting my PPL took priority, so I sold the EVO and Turbo Yamaha FZ07.
Jealous, T56s have skyrocketed in price. Have you seen the company that makes the bolt on sequential pattern for the T56? Are you a single disk clutch? What brand pistons and rods? I was thinking of going manley or wiesco. I'm waiting for the machine shop to give me sizes.
I suppose you're right about the stroke. Especially if I want revs. I have a friend who's running a procharged 408 in his G8 making just shy of 1200HP on 12-16PSI(?) That car is just silly.
From what I've found, a 80/75 should give good response (with the right cam and stall). You just have to be careful with header diameter, T3/T4/Vband, and going too small on the hotside housing. Ya know, volumetric stuff. Like how 8psi from a big turbo is substantially more than 8psi on a small turbo.
Apologies to everyone else for turning this into a car forum.
