So for my turbo install (if I ever get around to it) I've read about upgrading the stock MAP sensor so when under boost my car won't throw CELs.

I found Motorola 2.5 bar map sensors on EGay for $25. Says they are for Honda/Acura D16, B18, B20 and H22. Obviously requires soldering, nothing I can't handle. My question is should I get one? I'm not sure what psi I'll be running, I'm shooting for 230-240whp with my setup and I'm thinking to get this sensor if I end up running more than 10psi...

 

The stock MAP sensor will read up to 11.2 psi. There is no need to upgrade unless you plan on running more boost than that.
