Look, I know it's mean... 1.5L with a massive 1.6L head on it. Yea... Its a mean hybrid alright .... I put a Z6 head on my 1.5L B7. The head has a Zex Stage 3 Cam and fearro Springs and retainers. It doesnt want to idle right at all. Yea, I know its a big cam for a massive motor. It runs alittle... seems like its way out of time!!! I checked the timing and the dist. to make sure it wasnt 180 out. Everything seems to be right. I even tried moving the timing belt a tooth forward and backwards trying to get it right. Sounds like a tractor idleing. Firing order IS right, checked 100 times. When it is ruuning, I pulled the wire off Num 1 and it seemed to runn a little better. Put it back on and it sounds like its firing way off?? Don't know. I need help!! I dont want to have to take my monster to the shop, it might scare some ppl. $$$ Either way, it sucks. Free head, was running fine when i took it off the Z6. Need some help and info so I can get my BEAST stripping S2's...
