B17 type r swap Integra 1991

Hello everyone, I am new to this forum a friend recommended me this so I thought of asking about a Frankenstein swap/build that I am doing to my gs 1991 Integra that I’ve obtained for 1k$.

The car came with a b17a1 block stock / b16a JDM head. Unfortunately the ex owner had spun a bearing, regardless of that I accepted the challenge to experience how to rebuild a b series ( first time ).

I’ve found and bought from CT a block b17a1 bore 81.5mm and came with civic type r pistons, rings, b17 rods and b17 crank. It was wrapped in a box, unopened still after 4 years.

I assembled everything and gave me a good reading on the oil light/gap. Crank looked great, block look like it had low miles etc

I am also reusing the b16a JDM head that the car came with ( b17a1 stock spun bearing ).

So my idea was to swap block only and maybe upgrade its pistons ( in this case civic type r/ Nippon racing pistons ).

I sent the head to get a rebuild and resurface and came back looking great ( it was great condition regardless ).

So I am obviously new to the da9 b series as well since I’ve owned an ef si and crx before stock and restored from my part.

My question is do I have to check the valve to piston cleareance? How do you do it ? Anyone recommends any other methods ? Trying to acknowledge myself with experienced ppl as well so I would appreciate an answer from anyone with this kind of acknowledgement.

G2iC is great for platform-related questions, but you might have better luck getting engine building knowledge on Honda-Tech.

Until we get more users back here, I agree with @Kip-ft . You’re asking some advanced stuff and if you haven’t seen something similar here via a search, check there too.

Also, welcome :slight_smile:

What is your concern? Was the head decked?

Or are you making sure since the previous block spun a bearing?

You can check valve to piston clearance but if the head or block deck have not been milled/decked you should be fine.

If you are using a B17 block & its matching rods, you should be able to swap pistons without it changing piston to rod clearence.
