A buddy of mine has a crx with a b18b in it and its turbo. the problem he has come upt with is that after about 15 min of driving the car will not rev past 4 grand and it starts to run like complete ****. Please help and give me some ideas on what this could be so i can relay it to him.

Thanks guys

 

Firts off not enough info. When did this start happening,what have u tried to fix and does he have any cel's (check engine light) is he obd0 or obd1????????????

 

Won't rev past 4 grand? Someone else is having this problem right now too. Check the oil, and the igniter.
