So I've been building my ZHP and I've gone down a bit of a rabbit hole and I'm doing basically the whole front and rear end + vincebar kit + cooling system, vanos. I'd really like to take it to some track days and autoX next season.
It will realistically not be a full time track car but I do like to rev the engine out to redline on the street.
The cheapest solution is to safety wire the nut, I've seen a few cases on some facebook groups of the oil pump nut backing off on a tracked ZHP.
Then there is the upgraded shaft solution from Achilles. This is $250 with a prepressed shaft on the gear.
And lastly there is an oil pump baffle which is $150 + labor for welding to oil pan.
My car has 192k ish miles and I'm not sure of the state of it. It seems fine though and when I dropped the oil pan there werent any metal shavings or funny looking milky oil.
Should I just safety wire the nut and call it a day? Or is it worth getting the upgraded pump shaft and oil pan baffle?
Anyone here track their ZHPs with just a simple safety wire + overfilling oil slightly?
