You can get them from the US - Cometic MLS. You should also consider head studs (eg ARP - $$$ unfortunately), or at least some sort of uprated head bolts ---> see www.e30tech.com . You could also get your block o-ringed and use the standard h/g --> approx $100. Seems there are a few people (me included) looking for turbo parts at the moment. I've been given a price of about US$350 including freight (of US$60) for a MLS headgasket and ARP head stud kit for an M10.

Mike 1 Report post Posted June 15, 2008 thats a good price cam, I'm sure i paid $350 excluding freight for an MLS and ARP head stud set after loys of hunting around. IMO either go O-ring with stock HG or get standard height MLS, thicker gaskets lower CR too much and upset the cam timing a tad too. TCD sells M20 MLS at a precent decent price from memory. also agree on the head studs, M20 ARP set can be a little tricky to track down. Also have a look in yellow pages for gasket makers, few firms out there in NZ that will fo MLS gasket or copper. costs a little more than importing one when i checked with them Quote Share this post Link to post Share on other sites
CamB 48 Report post Posted June 16, 2008 thats a good price cam, I'm sure i paid $350 excluding freight for an MLS and ARP head stud set after loys of hunting around. More specifically, US$140 for the MLS and I was quoted a (very) wide range of $130-200 for the ARP studs. $130 is a bit too good to be true... www.racetep.com Given I can get a standard headgasket for under $100, and o-ringing is $100 (for a 4 cylinder), I am tempted to stick with that option. On top of that, M10 (but not M20) head studs are non-stretch and have a reputation for being pretty strong. They're not that expensive new, or I could re-use... Or I could go the full deal and get MLS, ARP head studs and JE Pistons from racetep.com for ~NZ$1500 landed in NZ including GST. It's very tempting, although if I went down this route I could easily spend the same again having the block bored/decked/crack tested/etc, the rods tidied and getting everything balanced and assembled.

Driftit 2001 Report post Posted June 16, 2008 There is a company in Auckland that will make any gasket you want. Mate purchased a multilayer metal one from them. But I just can not remember the name of the company. They are very cheap. If they dont have the template they just get you to bring in a stock one to copy.
