This is a T56 six speed Tremac short input shaft bellhousing adapter built for the 4G63 and 64 first and second gen turbo narrow block engine.Built by Bills Auto Fab in Toledo,Ohio , the world leader in converting the FWD Mitsubishi engines to RWD.Check us out at www.projectzerog.com
These bellhousings are built to use either the fwd or the rwd flywheels and they can be machined to fit the 4 through 9 evo engine, the first and second gen 4g63 and 64 narrow block engine. They use the original flywheel/starter and pressure plate, the disc is a stock Toyota disc.
You can see the build at UltimateSubaru.com under subaru transplants
The W series is the most cost effective and popular bellhousing adapterthat I build. Any w55 through 59 Toyota transmission is a direct bolt up to the 4G63 narrow block engine using all the clutch parts from the donor trans and existing engine
The w series bellhousing continues to evolve. I am rebuilding the original design to include the EVO bolt pattern as well as the first and second gen narrow block bolt pattern and an alternative option of FWD flywheel or AWD flywheel.
I was asked to help with an automatic transmission set up for the drag race guys. I never wanted to get into it but guys at www.projectzerog got me interested They wanted the GM 350 transmission option, but they wanted it with an all GM set up. So I set out the use the stock GM 154 tooth flywheel to mate the turbo 350 trans to the 4G63
