In 16 hours my mechanic pulled my engine out of my mr2, machined my flywheel, fitted my new TRD clutch, changed the gearbox oil, changed the coolant, gapped and changed the plugs, took off the ct26 turbo and broke 3 exhaust studs and removed those, put on the ct20b turbo, fitted my aussie exhaust downpipe, made up a bracket for it, fitted my GReddy Profec B, put engine back in, bled coolant system and changed clutch fluid.
Not too bad an effort for 16 hours.
