I'm overhauling my D16A1 in my 88 teg (I know, I know, whats the point...) and I came across a set of zc cams on ebay. I bought them, but I haven't installed them yet (because I haven't actually taken the engine out yet). I was wondering what other kind of stuff for the zc will work with the a1? Anything I need to be careful about, or stuff that specifically won't work? I also found a PM7 as opposed to the PG7. Any difference?

ummm im not even sure if those cams will work, if they do im not sure how much more agressive they are than the OEM ones, i say this because i used to have a built ZC, and GUDE and HKS had diffrent part numbers specific to ZC cams never mentioned a teg, yes i know some parts are interchangable but not all of them, before you run them, you should check the comp ratio of a ZC and a teg, then check the stroke, then check the lift, wouldnt want to slap a valve with a piston!

The guy I bought it from said they'd be great in an A1. He seemed to know what he was talking about, but who knows I guess.
id clay the head and test it first, when i had mine i never heard of ZC cams being interchangable with teg cams, and when i had the list of parts that were interchangeable i dont recall cams being one of them, as far as your ECU goes, the teg ECU the one you have is a choice ECU, it is a little more agressive...as far as your cams, B-series cams are usually interchangable as long as you keep the vtec/non seperate, but the D series seems finnicky, and there are 2 types of valvetrains, INTERFERENCE, and NON-INTERFERENCE, interference means that if timing or lift is off the valve will slap a piston, non interference means no matter how shit canned it goes the valvetrain will never touch the piston in that year they were all interference...... you can try it, just be careful and do some reasearch

the ZC cams will work and are a lot better than the D16A1 cams
don't worry about piston to valve clearance - they have a ton of room - we have run aftermarket cams with .458" gross lift and .108" lift at overlap (which is the critical concern) on a DOHC ZC with head milled 0.080" and block decked 0.040" and stock pistons - when we clayed the engine, we still had all kinds of room - when we clayed the engine before milling the head and decking the block, it had over .180" clearance without a gasket
not much difference in the PM7 and PG7 ECUs in how the car runs - the PM7 has a speed limiter at about 112mph - i would use the PG7
lots of things will interchange between the ZC and the D16A1 - the best thing you could swap would be the intake manifold - the ZC works much better than the A1 - the ZC camshaft timing gears will not work on the A1 - some of the crankshafts don't interchange due to the diameter of the front snout - distributors, cylinder sensors, throttle bodies are all the same on both engines - i should clarify - this info is for the 88-89 D16A1 - the 86-87 D16A1 is different - the head castings and the blocks are not the same on the ZC and the A1 - all of the internal head parts are the same - timing belt tensioners are different - timing belt covers are different - valve covers are different
you cannot run B-series camshafts in the D-series engine - they are about 2" longer than the head - all of these engines are interference

maybe i was drunk and rambling, i didnt mean to say that ANY bseries cam will fit, i was just talking about their interchangability amongst other b series, and las i checked the ZC and the D series manifold had diffrent bolt patterns?? i remember i was gonna buy a skunk2 manifold for my ZC but didnt cause it was a diffrent bolt pattern, i dunno like i said its been a few years

yo there is a sOHC zc and a DOHC zc DOHC came in the early model integras ... our block code D16a1 is the same as a DOHC zc .... jus USDM ... u can put a z6 head on a sohc zc block but not a dohc zc block ... so yea if he sent you 2 cams instead of one ... its the same cams u already have ... hence... wasted money .
