putting a turbo on a 2.5 n/a diesel

i was wondering if you can put a turbo on a 2.5 n/a diesel? is it worth it? can the motor, trans, gear box handle it?

From what I understand it is not worth it as the motor will not like it. Land rover basically did this with the 2.5 TD and it is widely regarded as the worst rover motor. Save your pennies for a 200Tdi. it is basically a bolt in place of a 2.5 NA diesel.

And there are quite a lot of internal defferences between the N/A and TD blocks... apparently later blocks had all the "turbo upgrades" in them whether they were turbo'd or not.

you'll need to change the injector pump though, as the turbo one is different.

Some folk on the UK forums have intercooled the TD engine, not like a Tdi to get more power (with extra fuelling), but just to make life easier for the TD engine, and with good results.

If it is a later block it will have the upgrades and turbo oiling passages already in place. If not, do not bother.

I am told there is no such thing as a 83' 2.5 na. My information is that 84' is the first year of the 2.5na. 83' should be a 2.25.

Regardless it sounds like an early version. J suffix block is the late choice I think.
