ok i have a cx/GSR hybrid and spun a rod bearing a few weeks back and have decided to build the GSR, i already have ITR pistons, rod and a new crank.

my car is taking way to long to get back together. so ive decided that i need a car cause its really taking a toll on my family (school and work) and so i thought about buying a d16 and putting it in but that id have to convert everything back to d series (axels, ECU, ETC.)

i dont know why i didnt think of it before but it would be cheaper for my to just buy a b16 longblock (abouit $500+shipping) and use it.

so my questions are:

-is a b16a1 pre-OBD or OBD 1?

-what do i have to do to convert it to OBD1?

-will the p72 throw codes due to the secondary butterfly?

-can i run a GSR manifold on a PR3 head?

-can i just put the B18C head on?

if i can run the P72 head on the b16 block i'll prolly just use the pr3 head on the motor im building w/ a chipped P28 ECU

SCC did it in there project civic so i know its possible, and no i dont care about the legality of it cause its no worse than any JDM motor and my hillbilly area will prolly think my motor is still stock

thanks for your time...

 

-1 B16A1 is Pre-OBD (or people refer to them as OBD0)

-2 P72 will NOT throw a code for the secondary butterflies at any time

-3 Yep you can it'll fit.

-4 Yes you can. It'll go on, you'll have slightly higher bumped compression

HTH bro

pre-OBD / OBD0 but there is no B16A1, rather a first gen B16A There is also a rare version of the first gen B16A that is OBDI from the JDM Integra XSi - the motor is OBDI but it's with a cable tranny setup

Reuse your GSR injectors and distributor, rewire the coolant temp switch

No, there is no CEL for the secondary butterflies

No, not without some machining to make it fit

Yes it will directly bolt-on but lower the compression some

 

cool i think im just gonna go with the b16 bottom end w/ my head till i get my bottom end built
