Ok i have a D16a6head im putting on a d15b2 and i was told i needed a y7/y8 cam gear ...ok but was not told what belt i would use to make this work.does any body know? thx

 

bump, i need to know what belt i need to finish my swap......

 

use ur stock belt

 

if there is nothing wrong with the b2 head, the cam will fit, put it in and adjust the valves, use the stock belt, I have been running this set up for years, It's the first thing I did to my rex

 

when u put the a6 head on the b2 it also lowers compression.. i learned the hard way :-(

 

Your best bet is to just use the A6 cam and pm6 ecu. Also converting to mpfi will help you out a lot.

 

just a question but what if you use a pm6 without mpfi?

 

No. You should have done MPFI way before the head swap.

 

ok so use the d16a6 camshaft and cam gear in the b2 head with the oe b2 timing belt is what you guys are saying?.....and im doing the mpfi swap at the same time.

 

you cant cause the pm6 is for mpfi ,not dpfi it wont work....

 

yes the pm6 will be lookin for two more injectors and sensors that the a6 dizzy has that the dpfi doesn't and i had a d15b2 with a6 head and single cam zc cam and had to run cam gear and it ran like a champ

 

You will need an a6 distributor, a resister box, a pm6, the intake mani with everything, the timing belts are exactly the same, and so are the cam gears, the heads are exwactly the same except for the camshaft, it will not lower your compression, you will need to repin the dizzy plug to the old one so you don't have to splice the two plugs, you will also need to run wires for the two new injectors to the ecu, get a chilton and look in the back for schematics

 

yea i got everything already im just going to replace the valve seals and put the cam in ...thanks for the input

 

yo the 1991 honda civic 4 door sedan do they come with 16a6 si engines? j/w i might sound stupid cuz all the ones i seen were dual point n ****

 

speak a little more clean, but yes but his is also dual point but you can also convert your to multiport and use an a6 camshaft and it will run much better.

 

Umm, they are the same head csating.... you did something wrong if you lost compression.

 

the 1991 hona civic sedan , they all come dualpoint right?? cuz my boy just got one and his got an si engine in it stock j/w

 

nope

 

The EX sedan came stock with the D16A6 MPFI engine.

 

Not necessarily....The carbon build up in the old head adds to the compression #. If the new head was clean, the dome space was larger without the carbon build up, thus lowering the compression. Also, the thickness of the (hopefully new or re-useable) head gasket would also effect compression #'s. This could be the scenario. good luck
