Discussion and technical advice the SW20 MR2. 3S-GTE, 3S-GE, 3S-FE etc
Anything and everything to do with maintenance, modifications and electrical is in here for the Mk2.
I'd say 2-3 hours - depends if you've done it before!
Probably worth changing the throttle body gaskets while you're at it too
EDIT Also gotta allow a couple of hours for giving the rocker cover a shiny new coat of silver too
