Thread: Long Motor 300tdi

A long motor doesn't include a gearbox. Long engines are basically rocker cover to sump with no manifolds, oil coolers or any ancilliarys. This is a Mitsubishi 6D14 truck long motor off my floorstock.

Before you replace the whole engine, assess what is needed first. Heads are readily available and the bottom end may be fine if not for a bearing replacement. Early 300's had a problem with the composite head gasket and a modification was made. The late head will fit both early and late versions and uses a steel laminate gasket and is also a huge improvement over the early ones.

PM me if you need further details.

just going through the process now not much change out of $9g by time you add in all the other little bits such as filters, oil, coolant, gaskets, it's suprising how all these little things add up to. was quoted $6500 for new crate engine but then still need injectors oils etc so either way you still forking out a heap.

$6500 is cheap for a long motor, I was quoted near $10 out of the crate about 2 years ago for a freinds car.

A long motor needs manifolds, turbo, injectors, water pump, power steering pump, alternator, air con pump and all the braketry changed over as well as lift pump, vac pump etc etc.

A long motor is basically a short motor with the head bolted down and no more.

If it's only going to cost $3k to fix the one you have, fix it as there is no cheap way out of it.

But if you have $10k to spend on the car you could slot in a new crate engine and rebuild your box and then the heart is all new and you will only have to worry about everything else.

A TDI disco or fender is not worth having 10k spent on, the bottom ends seem to be fairly robust so i would just replace the head if you need to and re use the ancillaries you have.
