This is my first build. I picked up a b18c5 block from a friend and I'm planning on re-building it with all oem parts. My goal is around 200whp-220whp. I want to use skunk2 stage 2 pro series cams in my b16a2 head that i have with upgraded valvetrain, also all supporting mods i will have to. I unassembled the motor and everything looks fine, little burn from cylinder 2(on the rod) but all parts will go to machine shop and be checked professionally. For the block I don't know what I need to have done, this is where i need help or ideas. Mainly if i should go with civic type r pistons or stay with the stock itr pistons? If I have to get it bored out to fit the ctr pistons? What i should replace? Where can i get bearings from or should I use ACL bearings? I'm real confused so any help or input would be great or a suggestion. Thanks

Why OEM parts? Upgrading to better slugs will help significantly and won't hurt reliability. The CTR pistons are NOT the way to go. You can get the same compression (really should go slightly lower than CTRs) with aftermarket pistons and have a much better dome design, make more power with less interference with the flame front and more clearance for the valves.

Best of luck with your project.

 

Thanks! A few friends of mine told me to just use OEM, I'm not going for anything crazy and idk why, I just want to use OEM. Should I just stick with the itr pistons? Bore it out? If I went with aftermarket pistons, etc.. what should I use and size etc???

 

also at about the npr or nippon racing, that stuff on ebay? is it garbage or good? I seen that question asked I just didnt see a good answer....

 

id avoid the ebay stuff. i would get itr pistons, wait to hear from the machine shop to see if you need boring. if you do, just do the next size up for the itr. if not, you really dont need to bore it out to get 220 whp.

 

sweet, i have itr pistons i just dont know if there is anything wrong with them, they look fine....

I'm gonna call the machine shop I'm going to use soon and see what the guy says.

 

bumpin this thread back up because I still am undecided on what to do with this type R block. I want to do whats right for the motor so if anyone can give me like a list of everything i should do and what parts and brands to use would be great. As it sits right now its a bare type r block. Thankss

^^ thanks, thats some good info there!

What kind of acl bearings should i get? what do i need to do to have those installed? or what to look for? This is my 1st thats why I have so many questions. Thanks again

 

Don't worry about the type of acl. You should choose either OEM or acl that will give you the correct clearances. For street cars, I like to run 0.0018" for both the main bearings and the rod bearings. One way to help with this is to read the bearing codes on the crank and the block and then use Earls chart to select the size based on what will give you the desired clearance relative to the standard 0.0015" clearance. The other way (recommended) is to have the crank journals and block bearing races measured. Then you can use Earls bearing chart to give you desired clearances.

 

I think I'm going to bring the block to a machine shop and see what it needs and how much it will all cost. Does anyone have any experience with nj machine shops or how much it could cost to get everything checked out, cleaned, and re-assembled...not including the parts I have to put in to it??
