Quick question about tach after swap
As I've said before, I recently bought a Del Sol with a B18C1 swap. The guy I bought the car from had the swap done at a shop. My question is, is it standard practice for a shop to recalibrate the tach after the swap, or does it even need to be recalibrated? The car is an S model so the dash redline is around 6000, but I'm wondering if taking it all the way up to 8000 (going by the dash) is such a great idea. I usually shift by 7000 because the engine is already going crazy enough at that rpm (and I rarely do this anyway). I'd hate to destroy such a beautiful car and engine. I suppose I could contact the seller again, but I was just wondering what is normally done with the tach after a swap. Thanks for any help.

Don't worry, the stock revlimiter is very safe, it'll cut fuel before you hurt anything. I doubt the tach can be recalibrated but I'm not sure. These motors are built to hit 8000 everyday.

Yeah, I guess I just got to thinking about how the tachs on the engines may produce a different output signal. Some voltage could mean 6000rpm on the stock motor and that same voltage mean 8000 on the B18C1. But, would it be possible I still have the tach from my stock engine, or is that replaced in a swap? If it's the same, there's no need to worry.
