om314 upgrade options? - ponkokanada - 04-27-2013
I recently bought a 1981 Mercedes 508d campervan project. It has a very rare om314 engine and a 4 speed manual transmission, 171 000 kms...runs like a dream, except it's reaaaaal slow.
Form the research I did on the engine I found the following:
3.8L 4cyl naturally aspirated, 80-85hp,@1800 RPM.
Direct injection, side valves, long stroke.
Considered to be indestructible: usually 1/2 million miles between rebuilds
Way more overbuilt than om6XX car engines
Question:
What can I do to squeeze more juice out of it?. I know 100+ hp factory turbo versions existed but were very rare.
If I were to install turbo in it, how easy would it be to get IP adjusted/modified to give more fuel (engine is directly injected)?
would it be safe to add more than a few psi of boost considering how beefy this motor is? I don't know if turbo versions were upgraded with stronger parts or features like piston cooling jets (similarly to om6XX) so I wonder how far I could push it.

Sounds like an OM314, what´s the # on your IP?

The turbo engines had piston oil cooling, stronger internals, .....

Ermagrrd, that thing is AWESOME
Also, I'm sure dieselmeken could do some magic with that pump to squeeze a little more power out of it, but you'll need a turbo and everything after the flywheel will need to be strengthened lol

Side valve diesel? I didn't think it was possible to get practical compression ratios from a side valve engine for a diesel to work well.
