Hi guys,

I have a 92 Del Sol running on a VTEC D15B JDM motor and i have been searching rebuild kits on ebay for upgrading to forged pistons and rings etc. however most of the rebuild kits are not compatible with the "JDM" D15b VTEC.

According to other blogs, researched that if there is no number on the engine ID (i.e. D15b1 D15b2 D15b7 .....) the engine is Japanese If I am not wrong?

So i need to know which one of the USDM rebuild kit would be compatible to the JDM D15b ?

 

No final number doesn't mean Japanese, it just means "Not American". There are plenty of other countries that got engines without a final number. Is your engine one of the ones with the P2J head stamp?

 

thanks for the reply friend.

I have not checked that yet... where is the P2J head stamp located?

 

Found it. its P08-6.

 

yea i posted on the 6 year old thread coz no one replied on this one including you man.

 

Bumping a 6 year old thread is much more likely to get you unpleasant answers than waiting patiently is. We have rules for a reason. Please re-read and respect them.

A little bit of research would show that the D15B VTEC has the same bore as the D16Z6. Your head code is also that of a D16Z6 casting. The rod length is also the same, but the stroke is slightly smaller on the D15B. That would lead the average person to believe that a rebuild kit for the D16Z6 would work, but you might need to source different crank bearings.

These are all best guesses based off of simple research, though. It's part of the "JDM tax". If you want a foreign motor, you need to be prepared to put in a little more effort than the average person in sourcing parts. Fun fact: Put "D15B VTEC rebuild kit" into Google, and the first result is a company that sells everything you need, with a phone number you can call to make sure it's what you need.

 

Thanks for the help man. I guess the best thing to do is to get a JDM kit.

Cheers

 

Please copy paste Rules here that you have mentioned above so Id avoid further violations.

 

That would be the most sure fire way, yes.
