Ive put my sohc vtec engine in my 89 crx and need the autogage to activate the vtec, is there any website that have good price for this. I have also heard i can use any rpm switch, but i think the autogage from autometer is easier.

 

On this wounderful thing called the internet that you're using there is this even more amazing thing called google try it

 

You mean to say you need that big *** tach to switch it over

Obviously someone wasnt doing homework, and didnt find out MSD makes an RPM based relay switch that you can wire in, even change out the rpm pill so you can adjust the Vtec RPM. You can probably get a good price on it at Summitracing.com

You can also make your own...from parts at radio shack, wiring diagram was at Honda-hybrid website a while ago....
I guess you can try and google it though
