[Mk2] [Turbo] ARP Main Studs - Sump modifications required for clearance?

Post by rossonza »

Hi guys,

im buying all the bits to forge my engine at the moment, and found some chatter on some US forums from 2010 ish stating the main studs if using ARP are too long and hit the sump the flywheel end of the engine.

Has anyone modified their sump? or used toyota bolts instead etc?

Cheers
Ross

yeah i had to modify mine, few people just leave that one as standard
If you see an MR2 with a raised engine cover, the bottom line is it's probably faster than your car.
