He can have my ECU in exchange, it has that error that thinks it is connected to a manual transmission.

You want to find for yourself:

A flywheel/clutch kit from a most-recent London Taxi in the UK. They're powered by the 2.5L version of the R2816 in the KJ, and has the same bolt-pattern on the crankshaft for a direct bolt-on. It's a solid mass flywheel, so no dual-mass to break with the higher-torque levels from GDE.

While you're ordering parts from the LTI, get a bell-housing as well. It'll bolt right up to the MTX or ATX engine adapter plate (NSG370 and 545RFE used the same bellhousing pattern for KJ diesel). The bellhousing from the LTI application is what I call a "normal" bellhousing (like on a SBC from a 60s/70s car) and already has a mount on the side for a hydraulic slave cylinder. The NSG370 has, of course, an integrated bellhousing with the case.

The NSG370 as you know was the std trans for the KJ 05-07 diesel, and also still be used in the most recent model year in KA/KK/JK diesels in Europe. It'll handle anything this engine can deliver (the DMF is always the weak link, but you'll use a solid flywheel anyways so no issues).

X2 to Dual Mass Fly Wheels SUCK!!!

When you get your setup together, spray on some Stress Coat. If you have any weak points the Stress Coat will have lots of cracks. When I made a custom adapter plate to hang a 1.6L VW Turbo Diesel onto a Type II trans, I did not follow my own advice and had to redo the adapter plate out of solid steel.
If you don't want to hunt and fight for the London Taxi flywheel and bell housing. Another flywheel that comes close can have the hub cut out, a new hub made, and TIG welded into the hole. The CRD flex plate hub can be the template for the pattern and the ring gear can be removed by cutting the stitch welds, making the surface a little larger than the ring gear ID and the ring gear can be heated up and tapped onto the fly wheel. Then have a speed shop type machine shop balance the fly wheel.
Been there done that on the VW I put the 1.6L Turbo Diesel into.
As far as the clutch goes, the splines in the hub counts as does the diameter. A competent clutch re-man shop can make what ever you want if you can't get what you want off the shelf. Just make sure you match up the torque out put of the engine the clutch is from with the CRD and your tune. Heck, places like Summit may have a Chrysler (Hemi?)clutch kit that will bolt on and work.
When I had my Perkins 354 Turbo Diesel in my C-30 I traded off om my CRD, I just did my home work and bought a clutch for a C-60 that dropped right in and worked great.

If you need to custom a bell housing and have it Sand Cast, 356 Alloy is commonly used in Transmission cases and available from foundries who do sand casting.

Good luck

Thanks for the input. Are you saying to use stress coat to inspect parts like at the machine shops or as a coating to use to aid in inspections?

The great thing about having McLeod manufacture my flywheel is that it will be solid, have there standard clutch pattern for multiple clutch setups and it's SFI approved, meaning, I can beat on it. The clutch I am using is a McLeod RST twin disc organic clutch rated for 800hp so it should handle at least 700 ft lbs. I ran one on a 2009 ZO6 I put twin turbos on and the clutch was just fantastic. That car made 646 tq at the wheels.

If this all goes well, I may private label a bolt clutch and fly kit for the CRD here in the US. That way this wont be such a crap shoot any more.

Okay why do you want a manual trans? If your plan on doing a SFA swap the last thing you want is a manual trans unless you like fixing broken driveshafts often,you can also forget any hope of keeping the 242 behind a manual also as you will get severe driveablility issues and why is was never offered behind a manual trans.

Don't say it's for better crawl ratio or anything like that as the auto you already have can be built(for a whole lot less $$$$) and will still end up with a better crawl ratio after you add in the TC's torque multiplication in.

Seriously or are you playing? lol
