Hi guys am following this with interest and plan on doing a similar swap. Have been on the Superturbodiesel forum talking to the merc boys.
I know a Swedish company/bloke on Facebook making a compound turbo om606 manifold, and am similarly torn between the number of options, like landroversforever I want around 400hp for a number of reasons, however in reality I want the driveability and low-down torque as well as the high-end boost.
I've come up with a few options that I'd love feedback on (if anyone's that bothered haha)
Engine - OM606 with Dieselmeken 603 8mm pump and tubular manifold from KKD or Dieselpumpuk
- Big single turbo i.e. Holset HX40 Super
- Compound setup
- Big VGT (no idea how to control it and can't rebuild)
Gearbox - Arguably more interesting - Must be able to take the power and couple with LT230
- Adaptor to R380 (not reliable with ~400lb ft)
- Merc 6 speed manual (available from many clk models) - Requires custom flywheel, clutch plate, pressure plate etc. No kit off the shelf as far as I know
- Nissan 5 speed manual conversion from 4x4fabrication.co.uk - proper job but not sure how expensive
- Merc 722.6 5 speed automatic, incredibly tough and meant to be very reliable, can add electronic controller (paddle shift in a 110!!) - Not sure about autos. I do know Rakeway sell an adaptor to fit the rear of this 'box to the LT230
Sorry for the thread hijack and anyone interested probably has this information already.
