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.

YES

You can use a P28 or a converted P06 or I believe the stock ECU is a P29?
If I am to replace seals and such on this motor are there USDM parts that I can use?
I'm pretty sure it uses all the same gaskets and such
Are there any quirks I need to know about this motor?
It has weaker rods than D16's, but they are all weak
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?
The 88 tranny has different splines. All 89+ have the same splines. 89 also has a smalled diameter clutch disk

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
mike

Re:D15BVtec Inquery
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.

Re:D15BVtec Inquery
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
