Hey everyone,

I own an 84 GS rx7 with 79k original on the 12a motor.

I have the change to get a rebuilt 13b street port built by Adam herman of rx7 specialities in Calgary, Alberta.
It's got:
- new housings
- apex seals
- e-shaft reused
- Lightened rotors
- new water pump

This guy I am looking to buy it off of is asking $4000 can.
It hasn't been used yet or even installed.

Do you think I should jump on it and buy it or should I stick with the two 12a's I have and play around with them... decisions.
