D15BVtec Inquery
 

Howdy HMT, I've a few questions about this sohc vtec motor. I used to have a stockpile of research but it is long gone. Will a DX tranny's splines match up to this motor, I just want to make sure that its not one of the Rare exceptions. Also, this motor i believe is OBDI is this true and does anyone know which ECU is designed for this motor. If I am to replace seals and such on this motor are there USDM parts that I can use? Are there any quirks I need to know about this motor? Also on 88 Crx Si's I heard the engine and transmission are splined differently than Later Crx's, does this carry over to the splines on the axles or will my DX tranny clunk right in? Thanks for the little bit of your life wasted to help me out.

Alex

Any D-series tranny will fit..the splines count is for the clutch plate it has nothing to do with the engine...

Re:D15BVtec Inquery
 

i'm buying the same engine next week. it has 35-45K miles
will it just bolt on?

would a ZC tranny be best for it? if not what would be best for it.

will a d16z6 mani bolt onto it?

any thing i should do to the engine thats needed for smog before i put it in?

thank you

Wait i thought 90+ has the same clutches
so 90-2000 are the same?

i thought 89 was different as well?


anyways, the d15b Vtec basically has a z6 head so you can use the p28 ecu. Any seals you would need you could get for a d16z6 and they would work for the head. The rods are smaller supposedly (noone really knows yet) On sohchonda.com there is a lot of research that is about to be done on the elusive d15b.

My buddy went to get a new axle for a 89 DX last night and they told him the 89 has two different spline counts on the tranny for the axles. They said it either has 23 or 26. I've never heard of a DX having two different spline counts on the axles. ???

Thats odd. I was under the impression that the 88 was the only Rex that had any splinage issues let alone axles. Thank you for all your responses Im having ordering-day paranoia. Must have faith in the 1.5

Re:D15BVtec Inquery
 

the original ecu that came with the engine was the p08

Re:D15BVtec Inquery
 

I have a D15B in my civic, all 1.6 parts fit right up to it. I have my D16Z6 head on it because the cam was actually better in it than the D15B. I'm using all Z6 intake parts, distributor, ecu, etc...

Re:D15BVtec Inquery
 

I'd like to see you use 1.6 rods and pistons in it. :P
