I recently aquired a 97 Disco (Freebie)and was wondering if there are any basic engine mods I can do that will enhance power such as air filter, exhaust, etc....</P>
I'm mainly familiar with American cars such as Fords and Chevys but I know SQUAT about Land Rovers. It hasa V8 so I'm assuming I can do the basic stuf like a K&N filter and free flowing mufflers and the like. Any suggestions? Brands? </P>
Also, any info on suspension lifts are welcome. Ideally, I'd like to lift it enough toput 33" tires on there. </P>

There are several ways to improve performance, though it depends what you want to improve.</P>
One is to fit a larger intercooler, Allard in the uk are a good starting point for that, also getting a new chip if yours has one fitted. K&N filters are also a good start as you know. </P>
With regard to lift, Bilston shocks seem to be a good place to start. </P>

Unless I'm missing something major, my Discovery doesn't have a turbo or supercharger so it shouldn't have an intercooler.?</P>
I think I'll just start with free flowing mufflers and a K&N Filter for starters. </P>

Here is a website for you to have a look at, http://www.scorpionracing.co.uk/OFFROAD/offroad.html</P>
They cover a range of modifications that you can either try and get from them or maybe find more local.</P>
Hope it is of help. <IMG src=smileys/smiley1.gif border="0"></P>

i wouldn't run the k&n ,hotwire mass airs don't like sucking oil fumes.i would start with a borla or nrp exhaust & high flow cats.superchip sells a chip but its $500.add magnacore wires.you can even look for a 4.6 from a 96-02 range rover when your 4.0 gets tired</P>
for your lift i would go to http://www.expeditionexchange.com/index.htm run ome 764 springs in the front & 762's in the rear w/ 1" spacers& EE backing plates for shocks run ome n73's in the front & n76's in the rear,you will have to fab new lower mounts or use n44's & EE shock mounts.you may get some driveline vibrations too, some do some don't, a dual card. front shaft will usually fix that.i would replace the roto-flex rear driveshaft with a u-joint one from a discoII or one of the kits.http://www.rovertym.com/also sells 3" springs and offsett arms.and with 33's you will need gears the only place for them is http://www.greatbasinrovers.com/</P>
