View Full Version : CTS-V T56, LS1 with an early 6.0 crank .400" extra flange, starter not work. Help.

Ok, so I am getting further and further into this nightmare of mine. I had an ls1 in my FC Rx7 mated with a t56 from a CTS-V. The bellhousing was a little longer and it came with the dual-mass flywheel so it made no difference (other than the heavy ass flywheel).

I threw a rod through the block and ended up having to get a new block that came with a crank. The block was a 5.7 and I never bothered checking the flange on the crank as I never knew they were any different. I got the engine put together and the first problem I ran into was the CTS-V dual mass flywheel not fitting or the bolts catching thread.

I ended up ditching the CTS-V flywheel and getting an ls7 setup from a forum member and everything fit. I order the Katech spacer and realized that I didn't even need it because of the crank. Now the starter won't catch and I have no idea what to do short of completely taking my engine back out of my car and rebuilding the engine with another crank. Halp.

I also realize the starter will not catch because the flywheel is sitting .400" of an inch too far away now. How do I work my way around this?

You have the flat or curved flexplate?
