Can I put a d16a6 head on a d15b8? 16v head on an 8v motor, will everything work out right? Same head gasket? same timing belt?

 

Someone on d-series.org answered my question

 

im not sure but once i put d16 vtec head on non vtec d serries block and when vtec crossedover valves hit pistons so be carefull

 

the 16 valve engines have 16 valve pistons, with 4 little gruves in them, So the valve dosnt hit the piston. 8 valve engines(d15b8) has 8 valve pistons, with only 2 little gruves in them so if you put the a6 or b7 head on you will have 8 valves hitting your piston

 

not all of the d15b8's have 8valve pistons. Most of them have 16v pistons. 4 reliefs per piston.

 

I did the 16V swap on my POS D15B8, ran an LS ECU to 10krpm, Y8 intake manifold, B18B Throttle body, and Y8 Transmission..... it was pretty quick until the valves fell out.

 

is there anyway to tell what kind of pistons you have withoot taking off your head?

Yeah, there is, just ask the guy who put them in.

 

well the motor has never been touched can the dealership tell me?

 

What's your vin number?

 

how can you tell from the vin? I would rather not throw me vin number out there

 

so then if you have a obd-1 d15b8 motor from a cx and you are trying to put a obd-0 head on what do you all have to change or do your use your same dizzy and ecu?
