Have an R33 Vspec. rear end is kinda drifting all over and hicas light comes on and goes off... sometimes. Thinkin the motor is bad. any way to check JUST motor? I'd hate to get rid of entire system if I can just buy a used motor or have this one rebuilt. It looks pretty simple and we have a shop here that rebuilds motors, starters, alternators etc.. for pretty cheap. Got GTR alternator rebuilt for 78 dollars US,Starter was done for 43 dollars about a year later and it was done in two days. with a warranty.
