As an owner of a Honda B15C2 looking for info online is a PTA
A search for B15C2 on most Honda Tech forums returns nothing.

So here are some pictures to help out fellow owners of this particular modell.
If your like me you will spend weeks looking for info and find little or none.

All I wanted was to buy a few items as in our country Honda support and sales suck. Its been 4 weeks since my drive shafts have been on back order.
They do not sell any parts. The car must be brought in if you want a part.
May as well bend over if you need a part. Labor rates are absurd.
Their part prices are also absurd.

Aftermarket parts are all china junk.
Only option import the parts from the USA and pay a 100% import duty on shipping and part price. So you better get the right part cause trust me you dont want to spend a few days bribing your way thru customs to clear your shipment.

Stuff Im still looking to buy if I can figure out works with what.
a. Forged Rods. Eagle / Tuner Toys / Etc.
b. Forged Pistons which will not drop my CR or be +- 2mm on the deck height after you install them.
c. Brake Pads
d. Clutch Plate
e. Top end rebuild kit seals and gaskets.
f. A larger TB say 60mm As the mani and TB on this engine is crap. Need Y8 Intake Manifold. Or Fab one.
g. Figure out if I can just get CV Joints or must I change the drive shaft.
h. Figure out what ECU this car runs and if it can be chipped.

My target is to make 200 BHP. NA or turbo not sure. But a 14 sec car is enough for me.

Enjoy the pics.
I will keep adding to them.
All my e-mails to vendors asking them for B15c2 parts get returned with a sorry we don't know that model.

Hoping these pics help me find the parts Im looking for and will help others who are in the same boat.

The pics can be found here.

Here you can find some good info on picking the right piston.
http://heeltoeauto.com/httech/YaBB.p...1160787887/1#1
My idea right now Vitara pistons with Hastings rings and a slightly longer rod to get my deck height spot on. That would be a cool and cheap combo.

Rod Specs
Top end pin dia 19mm
Bottom end Pin Dia 48mm (Without Bearings)
Center to Center should be 137mm

Piston Specs
Pin 19mm
Dia 75mm
Compression height (center of pin to top of piston)=28mm
height total=47.25
Marking=P2CY

A B15c2??????? Looks like a D15b if you ask me judging by your pictures..Honestly I've never heard of it either, that could be why you are having trouble finding parts

chinoy

finally some sympathy lol.
I was hoping you guys could look at the parts and go this is what will work.

i was told on my forum. that its a D15 Block with a Y7 head.
dont know if that helps ?

spent something like 100 man hours just looking for some basic specs on the vitara pistons not a single sketch just some pics and a lot of long posts.

Nichelson_Performance

yeah the vitaras will work in any d15 or d16, bore specs are the same, rod specs may also be the same too, not positive though...i think the stroke on the crank is different between a 1.5 and a 1.6

hopefully you are thinking about a turbo with using vitaras...they are super low compression which is not meant for N/A applications...do some searching on P29 pistons for N/A if you want to go that route, I do believe they will work in 1.5's also

you may also want to look into a vtec head swap whether it be a 1.5 vtec head or a 1.6

go to FJ distributors, they have a listing for vitara/eagle combo for a 1.5

chinoy

Im not a big fan of drooping the CR to run boost.
I believe is keep the cr stock or even bumping it up by .5 and then boosting.
Droping the CR and then boosting is only worth doing if your going for insane boost not a daily drive.

Nichelson_Performance

well i run the vitara/eagle combo which puts my C:R right around 7.8:1 and I daily drive my car everyday on 20psi of boost and never had one issue and the car drives identical to stock during part throttle even with the low compression ratio

so my advice, if you want stock or higher compression then vitaras are not going to work for you even with the FJR spec rods because even then your C:R will only be around 8.8:1 or even less with the d15

chinoy

Why would I want to look at a Vtec head swap when I already have Vtec ?

chinoy

One more question guys.
It seems the JDM version of this motor makes 130 ps.
Honda sold this car as 106 BHP at 7000 RPM.

Since its allready got a D15 bottom end.
And a Vtec 16 valve head.

What do I need to change to get to 130 ps. ?

Dwreck

Well since we never got that motor in the us, i couldnt tell you how you can magically get another 24ps. Either they put a more restricted intake manifold or cam into it. Or i have no idea.

The IM is the shitty Y7/Y8AT one. Ron, I've heard that doing a simple Y8 IM swap along with the corresponding Y8 ECU should free up a good amount of power. Freeing up the intake and exhaust should help you reach your target. The ECU in the OHC VTEC is an OBD2B JDM-size PJT ECU. Cannot be chipped like the OBD1 Honda ECUs.

dont know if that helps ?QUOTE]

this is why i stated about looking for a vtec based on one of your posts because a y7 head is non vtec

plus the jdm 1.5's do have 130hp which also have vtec, so if your's is only 106hp i highly doubt its vtec

chewyv

I would like to know where you got code "B15c2" from

cyanid3

Honda used to sell a mini-me as B15C2 in India. The block is labelled B15C2 and head has P2J-6 on it.

chewyv

sweet nector! I didnt know they just mix things together and gave it a name...

chinoy

You have no idea as the kind of old crappy tech we get sold. And at what inflated prices.
Its like they find some spares in a back room and some moron pieces it together and calls it an engine.
If you ask them why. They say its cause you people are obsessed with mileage.
What mileage I get 6km / LtR.
Ps: Its a vtec. I should know. held out for months to find it. + The Valve cover says Vtec. + It has the V-Tec Solenoid.

chinoy

Yes I plan to either fab up a custom mani or got ITB.
Just hate tuning with ITBs. The map is always a bitch to deal with on ITBs.
Or Ill keep a look out on ebay and here for a y8 Mani. Waiting for a good deal.
But you know what a hassel it is getting down parts and dealing with customs.
Even though Ive been exporting stuff for a decade hate importing stuff.

On the ECU it would be simpler for me to try something here only.

chinoy

why do you say it cant be chipped.
Did you show it to some of the guys who chip these ECUs. ?

If they are able to chip the OBD0,1,&2 ECUs whats so special about this one.
Can you keep an eye out for for a good ECU

Also got some club boys in the UK and US hiting up the junk yards they want to know what car they should pop the hood on to find a Y8 mani ?

chinoy

thanks for sharing cynide. I can see why nobody wants to chip it.
its all SMD. And very different from the older ECUs.

I wanna see pictures of the B15c2 stamp otherwise I say you're full of it. All Honda B series motors were DOHC.

Korman

No they wern't. All *modern* B series are DOHC. Don't forget the old Prelude B-series, they had both SOHC and DOHC versions.

Not only that, but *modern* B series heads can be mounted on *old* B series blocks with some modifications. Personally, I'd love to see a B16B head on a B21 block... but that's neither here nor there.

With stuff like that, and the fact the some D series were branded as ZC's, and some D series were DOHC, the fact that there might be something like a D series branded as a B series really doesn't surprise me.

DCFIVER

Wrong. ALL Honda B series motors are DOHC. The early generation Preludes (up to 4th gen) came in both SOHC and DOHC configurations. The Preludes that were SOHC utilized Accord motors. The 1st-3rd gen Preludes used the Accord "A" series motor and the 4th gen used the Accord "F" series motor, which were both SOHC. There was NEVER a production B series single cam motor. Get educated son!!!

Rude Awakening

3rd gen Prelude S has a B20A3 which is SOHC carbureted at 102HP.

Get educated son!!!

Korman

ROFL I completely agree. Some random guy is telling me, who is going for his doctorate, to get "educated"? WTF is the world coming to?

HAHA lesson of the day - Don't SHOUT your bullshit and act like a smartass if you don't know what you are talking about.
