I shut my PM's off as I was getting too many 2LTE related questions. Also I prefer to help out in the main forums where it benefits more than one person.
At this point I recommend you read some LJ78 build threads on here.
@Jarrat @Nas90tdi @Postoy @malteser and others have some very well documented build threads. I don't have time to find them for you, but if you search by their user name you should find them pretty quickly. Those four builds will give you an excellent idea of how you should proceed.
Also, download all the manuals and get familiar with them. I've posted them countless times; here is one location:
Help!
From my experience though:
- First thing I'd do to the vehicle would be catch up on maintenance. They're all behind. Brakes, tires, fluid flushes, grease, front axle rebuild (go to manual hubs right away, you won't regret it), t-stat, timing belt, water pump, belts, glow plugs, viscous fan clutch service, exhaust repair/replace, etc. Check engine compression before you start dumping lots of money into it.
- Add some gauges. At the least, boost and pyrometer. Coolant temp would be a good one too; although personally I don't mind the factory one.
- Next I'd remove the emissions system (EGR/PCV) and all related parts (VSVs, throttle plates etc.)
- After that I'd add a trans cooler inline with the radiator one.
- Upgrade radiator to a three or four core as thick as possible (get the original re-cored), and increase the fan size (2H fan from HJ60 is a direct swap upgrade). Coolling problems will become a thing of the past.
- An intercooler would be the next thing. It absolutely transforms the performance of these things. Allows tuning such that the thing will feel like a normal 4 cylinder vehicle. You should be able to out-accelerate traffic, pass other cars, and climb steep grades at posted speed limits after this mod/tuning.
- After all that, you can start looking at lift kits, bigger tires, bumpers, sliders, roof racks, winches etc.
