I dont know if he still has them, but thomas4parts on ozgemini had a batch of MLS head gaskets made up for the g200w, if you wanted to go that way, and ive taken measurements and it looks like sr20 pulsar GTIR SR20 head bolts will fit (ARP part number 202-4303). The standard SR20s are M11, but the Pulsars are M12 as are the g200w.

For the diff, the altra-9 LSD kits are awesome. I retrofitted the sailsbery diff to my TX with one of those centers and everything about it is awesome. As for ratios the DOHC gearbox is closer ratio than stock, but they are hard to find if there isnt one on your engine allready.

Hi F3ARED

Just a comment on the chains

I used the DR58 for the bottom and a DR118 for the top - exact lengths and pitch

Do you have the timing diagram mentioned earlier

Just to clarify further

this is for the blue top motor with the original oil driven chain tensioners not the later ratchet design

Cheers
