I am buying a 1995 integra gsr that was previously built. The engine had civc type r pistons, integra type r rods, and an integra type r head. The owner hydrolocked the engine and blew a hole in the block. I am going to rebuild it but don't know which b18 blocks I can use with the type r head. Also what would be a good piston and rod setup for this. It is going to be driven daily, but also tracked.

 

well you can use pretty much any b18 block with the head but it would just be easier for you to use either a GSR block or a type R block.... GSR being cheaper and achieving same goal if you are replacing internals. As far as pistons go it all depends on what kind of setup you are doing and what kind of numbers you are looking to make. For turbo you need low comression and all motor requires higher compression. Just guessing that from driving daily you are going with all motor and I would go with type R internals.

 

I was planning on an all motor setup. The block is seeming harder to come by then I originally expected. I found a b18b block but a gsr block is what I would like to have. On the type r pistons is it better to use civic type r pistons for the higher compression or do I have to worry about valve clearance. Last question is can I run a stock Gsr ecm with this setup.

 

ummm i think that the ctr pistons are fine when it comes to clearance. Never done it with a ITR head but ive ran them with B16 heads and it worked out just fine. Either the ITR or the CTR pistons would be good but my personal choice would be ITR. You can run the b18b block but your gonna have to do a LS-vtec conversion kit such as golden eagle.

 

Figure out what bore the pistons are and make sure the block your purchasing isn't over bored for those pistons if you plan on re-using them.
The head should be fine, just find out how much the head has been decked to know what your final compression ratio is.
CTR or PCT pistons should net you in the ball park of 12.5-13.1:1 compression ratio. That is with .005mm being decked between head/block. A thicker head gasket either 0.054 or .o60" should keep you in the lower end of that spectrum.
