Ok, after seeing that TopGear episode where they use that diesel BMW to race, I always get the urge to want to build up my own track car. Now, not always the usual - obv. a Golf maybe isn't the best track tool, but what is. I know at least with the Golf I could run a 16v ABF KR at about 160 bhp reliably, or run a 2.0T with some minor mods, a Corsa could run with a red top at 160 bhp with a close ratio rallye box. I would gut the entire interior and only have a minimal dash - it doesn't have to strictly be MOT'able, but it would be nice.
I'd love to make a little racer, pushing a reliable 150 bhp (but with promise of upgrading to 250 bhp with minimal cost). But the plan is to make it reliable on a budget, what cheap mods help out basically, and for what cars?
I've seen a few MK2's where the front ARB has been replaced with one off a Passat with a little fiddling, which was almost twice the thickness. Upgrading the springs/shocks - whether the budget coily's are sufficient, I like the ones I have on my Golf and could imagine they would be pretty good on the track, obv a bit hoppy on uneven roads. Replacing all bushes with poly ones, stripping down the interior to nothing, fitting a purposeful rollcage, replace the side and rear windows with plexiglass, get low weight alloys and decent tyres.
But what cars (not just restricted to VW) are a good choice, given replacement costs of disks/pads etc. I'm not a pro and it would be something to learn in on track days, then progressing onto competitions.
Budget wise, lets say 3-4k, throw some ideas my way. Also, what kind of costs do you run into for a 1 day session, new tyres, disks pads, anything else, roughly - whats the running costs, how frequently do you change the oil etc.
