racing the ZC motor

[Akid]

Sorry if anyone is getting sick of me asking questions but im not familiar with this motor at all so bare with me.

but i was j/w if the motor is built well enough to constantly be raced, I dont want to blow the shit out of my motor or mess anything up.

Also I just put the 89' teg ECU into the car and for some reason the car is idling farely high everyonce in a while, it normally idles around 500 but sometimes sits at a 1300RPM idle anybody know why? thanks in advance you guys, and again im sorry about being so dumbfounded about cars

has the ZC been rebuilt, how many miles are on it. as long as it has low mileage you should be able to race it quite a bit, but any engine will eventually go if your racing it everyday
