I think one of the few people on here who have one, there strong motors as long as your tuning is decent. I've been running 7 pounds with no problems. Now I've got a t3/t4 and I'm probably turning the boost up to like 10-11. I guess we'll see how that goes. How many miles are on your motor? Compression?
The motors are comparable to the single cam D16's. The weak point is the rods. The Greddy kit for the 92-95 single cam Civics was actually made for the ZC in Japan first so the motor can take what that kit makes in terms of power.
yes dustin its in your old rex, i ordered a jdm zc it will be here today. but ive got some work to do before i drop the zc in. everyone who has posted i appreciate your help and input, lets keep it rolling, what do you think of painting a crx honda championship white? let me know, keep the posts rollin
i wouldnt go past 7psi on a stock block. ive have a d series on 12psi before and it lasted about 3 weeks before it throw a rod. def put what klink said on it before you go boostin away or you will be picking rod pieces out of your oil pan
