Turbo/Supercharger upgrade advise needed


Newbie here - so please do easy on me!

I have bought a Defender 90, 1990 Model, with a 2.5 Deisel (NON-Turbo) engine. I have been provided with an option to upgrade to a 3.5 V8 from a Ranger Rover (Petrol) which I am not too comfortable to do.

Another option suggested is to install a Turbo in the existing engine.

I have been reading (from the time I get). What should I opt for - a Turbo or a Supercharger? In fact my question should be - can a Turbo indeed be installed on a 2.5 D (Non-Turbo) engine in the first place? If Yes, some makes and reference website would be highly appreciated.

I am NOT looking for speed per se, I am looking for more power when off-roading. I have been told replacing the fuel pump, vacuum pump and starter/self and alternator (as the engine has been given a clean-health of bill by the Land Rover specialist here).

Thanks in Advance.

A turbo can be installed on your engine, but you would have to change the intake manifold to install it. Also, the bottom end of your 2.5 is not strong enough to cope with the extra strain placed on the engine by the turbo. Search the forum at lro.com for more info on this.

How in the world have I spent this much money and still don't have a running vehicle?

1990 D-90 with a 2.5 N.A. Hmm, that sounds extremely familiar. Chris is right, while technically you can turbocharge it, you will blow it to pieces in no time. The only thing to do with that engine is get rid of it. I bought a 300TDi with R380 and new t-case for 5k and sold the other drivetrain for 2k and did the work myself. That is what I recommend since the swap is very easy. Plus, it should be a lot cheaper for you not in the U.S. Don't do the 3.5.
