I have a question I have a 95 honda d15b7 and am rebuilding it to do a min me swap, But have some questions about the rebuild. I am going to use the stock d15b7 block and crank and putting in stock d16a1 pistons in and use the origanal rods from the d15b7, and put a d16z6 head to raise the compresion to 10:1 or 11:1.But the question i have is will the pistons fit and what the compression will be when i am all done and most of all will it work....

 

Google search: Compression ratio calculator...

 

The d16 piston is going to sit about .070 in the hole. Only going to give you about 9.5 to 1 compression with the non vtec head. 10.5 to 1 with a z6 head, because the pin height is different between then d15 & d16. PM me if you are looking for a real d15 high comp piston.

 

So if i dont use d16A1 pistons which ones should i use and the main consern is will they fit the stock block

 

I used the compression ratio caculator for honda motors and if I used the same componets that i listed before; d15b7 block, b15b7 crank, d16z6 head, d16a1 pistons, and d15b7 connecting rods, the copression ration estimates out to 10.46:1, So I was wondering how you get 9.5:1

 

He stated with a NON-Vtec Head your CR would be roughly 9.5:1. (It's actually around 9.3:1 depending on your head gasket choice).
