And your budget. And how much you drive the car. For me, I only get to drive it once or twice a month and it just doesn't make sense to blow $4K on an OD setup. I can buy alot of gas for that much dough. I tach 3300 at 70 mph. I can live with it. I have 3.23s and an M20. Maybe if I had 3.90s and I wanted to keep them I might think differently.
