Ran motorkhanas, khanacrosses & autocrosses for over ten years. Ran the 5k, cost $100 from the local paper :'( for six or so of those. All theat was done internally was the cam and a set of shells.
This isn't the best video but this is it in action
. This test was really to tight to let it have its head. Others that day would see the shift light on constantly, set at 7500rpm.
I would baffle the sump if you are going to operate on bitumen as the g forces generated would be much higher than I would generate on dirt.
Maybe just install a huge oil light and see how it goes. If you have an issue, then you could do your sump or see what people running Corolla's in hillclimbs have done.
Cost wasn't an issue for me Cameron, as I had no money to throw away, I just reused everything that I had unless it was stuffed :lol:. If it was, I then looked at what was in the shed or the old mans workshop and used what I could. That id why my KE20 was running a KE30 radiator, truck exhaust tubing, ke35 front brakes converted back to ke20 pattern etc........
I may be seem like I'm talking myself up, but I know a number of people who went down the track of doing this or that cause it was the done thing and they have ended up not going any quicker than me. I think this was down to weight as my KE20 had undergone a serious diet.
