I am trying to find a good write up on rebuilding a B16A with B16B internals (ctr pistons etc). I have searched and cannot find a legitimate write up on this. Any one know of any good write ups for this project? Please post them

 

I think you have to change the crank and cylinder bore too dont you??

You can hone the b16a cylinders to allow for a good fit with ctr pistons. Boaring it is unecissary. The crank would have to be changed if plan on reving past 8,000 rpm, but the b16a's crank has the same stroke as the b16b's, it's just that the b16b's crank is slightly heavier (20% more) to handle higher rpms up to 9,000rpm.

 

Bump. for answers.

 

What specific information are you seeking?

Keep in mind that the B16B uses a different block with a taller deck height than the B16A, so you cannot simply transfer the CTR internals over to the B16A. You can install the CTR pistons on your B16A rods for an increase in compression, but you'll have to machine the rods in order for the pistons to fit.

I'm looking to put in CTR pistons, but keep my stock b16a rods. Macheine the wrist pin hole on the connecting rod? I want to keep the b16a block as well as the valve train. So basically, this is something I have never seen a legitimate write up for on what you can and cannot do... essentially what i'm looking for.

 

Also, I would like to hone the cylinders instead of bore them out. New sleeves are pricey and I don't plan on replacing them. What is the most I can hone to allow a decent fit for the ctr piston? Questions like these are what I have.

 

To use the CTR pistons on your rods, you just have to machine a small amount from the rods (or the pistons) in order for them to fit.

Depending upon the condition of your cylinders you can either do a simple hone, or if the condition isn't great, you can purchase .25 oversized pistons and have the cylinders bored for them.
