Hello everyone, I am in the process of building up a b18c1 engine that will be dropped into my 1991 CRXsi. I have been reading thread after thread on how to go about this build and what things did and did not work for others. all the information can be a bit overwhelming and (as often stated) with b series engines you can start with the same engine type as a hundred people and build it a hundred different was, I comes down to what you the builder wants and how deep your pockets are.

With all of that said this is what I want to do, I want a fun reliable smooth running engine, yet a little more powerful than the stock daily driver.


I want to do a NA b18, here is my question can I run P3 or P30's with my stock GSR rods?


And if I can run those pistons on a stock block will I have to change anything in my valve train?

ps. if you know the name or member of a thread that has talked about this please let me know the title so i can read about it

 

The difference of a p72 to p30 isn't really from worth it even if you got this stuff free and judging by this question I don't think you're the one who's going to be measuring clearances. You would need new wrist pins and wrings obv, realistically bolt on would be a lot easier and still net you a enjoyable feel. A CRX is light as F instead of trying some advanced modification that's above you, start with bolt ons.
