I was just sold a d15b2 (dual point)motor/5speed from a crx to replace the d15b1 and 4 speed in my 91 ef civic. I have a multi-point head sitting in my garage that i would like to swap over also.

Is there anything that I should worry about before I make this swap over. Is this a direct swap over? Will this be a direct swap?

Any help would be greatly appreciated.

Thank you very much.

 

Heads are all the same, difference is in the camshaft and springs. Everything is a direct swap but you have to make sure that if you use the A6 camshaft in a 1.5 block you use the Y7/8 gear or adjustable cam gear.

 

I think I'm going to just swap the whole motor over. I was informed that I can get better gas mileage and performance after going to the d15b2 with the the multi point swap.

 

If there's nothing wrong with your current B1, it'd be easier to just swap the camshaft out and do the MPFI.

 

I'm doin the same swap only staying with the pgmfi set-up.. So I need a pm5 ecu? What about my std wiring same distributor & wire harness as the dx right? Only change is the ecu right? Any input is appreciated..

 

Of course I'm not gonna mess with cams & such.. I just want a bit more hp so I can get up a damn hill..

 

yes everything is a direct swap.

i agree with 24ten everything is the same. id rather swap camshaft and do the mpfi swap.
basically your doing the samething just swapping in the b2.

 

Ok, I know this will be a silly question but is there a write up on swapping out the cam? And possibly the MPFI swap? Thank you very much.

 

Google mpfi swap its been done a million times

 

I'm just trying to keep it simple.. I'm going remanufactured long block but I want the extra hp.. I'm looking at quite a bit already.. Anybody know of any reasonable places that sell reman motors?
