hi I was just hoping for some advice. I currently have an a2 and I was reading a post on here about what piston's are in it and saw they were pm2 but when a mate of mite broke his engine I had a look at the piston an here in the uk they are p1j's. so I was just wondering if they are the same piston ...

I was just wondering if anyone knows what the comp ratio is of a d14 wit pm2 piston's (at least I think that's what's in my a2) and a z6 head.

or even if anyone knows the any info on the pistons.

they do have an auto vtec ecu but trying to find one is a nightmare. how much tuning would need to be done if I just used a vtec controller? or could I get away with 240cc injectors and playing with the dizzy timing?

thanks for the info. was a good read but at the same time a little annoying as I have a vtec head and ecu but my ecu is for a manual and mines a automatic. unless the ecu doesn't control the automatic she of things? any ideas?

hi I was just wondering if anyone knows if its possible to run vtec with out the ecu being vtec i.e. on a vtec controller or something similar.

thanks. i was just wondering if you know if other cams fit in the a2 head same with the d16z6 head what other cams fit in them?

I was just wondering if any body knows what potential the head has and any specs for my a2 head as I'm not sure if its worth keeping or whither to use a head like the d16z6.

also does it make any difference having the spark plugs on the inlet side or the exhaust side?
