The engine runs great, ive only ever had 1992 japanese cars (2 charades, feroza, MR2, Hiace). My other daily is a 91 4runner. This is so much fun to drive, it pulls hard, revs high and just sounds awesome. The pinto in the car is not the original, the bloke said it was an exchange from about 3 years ago. As mentioned it has some sort of cam, I had my mechanic do the valve clearances, and he spotted on the cam "MADE IN USA", he couldnt tell me more than that...
Of course I would love a 5th gear, and if I ever find a box locally I would have to grab one.
I've got a spare 4speed that came with the car, going to suss it out and see what it is during the week, hoping for a rocket :)
