couldn't even tell you since they don't say. but usually ebay is not the place for engine parts.

 

i agree with "red army".. i've seen some pretty badd results with ebay product when rebuilding engines, but its really your call... research that piston a bit more before deciding, i've never heard of that brand before tho.. gOod luck with which ever decision you make.! :D

 

I used the 84.5mm version of those pistons in my b20vtec






results (with bolt-ons and CTR cams)

 

okei but is the block guard nessesery? for high compression

 

Only a suggestion but I wouldn't go cheap when it comes to engine internals. No need for a block guard, they cost more to have properly installed then they are worth.

 

honestly it all depends on the CR ur aiming for ...

 

It's not. I only did it because I'm using stock sleeves and I overbored them. I decided to add it for more "protection". I also added an aftermarket girdle and GSR arp main studs which the average person wouldn't have done. So I kind of went over boarded on a basic build. If you do decide to use a block guard, get it pressed in at a machine shop. Then get the cylinders check for straightness, and last get your machine work done. Most people on the forum say block guards are the devil, but I didn't care because I got mines installed properly.

(and please don't make this a debate about block guards LOL)

As for the pistons, even though those are "ebay" pistons, they are Nippon brands, and they make pretty good stuff.

 

okei thanks for that I think I'm not going to use block gourd btw in what theard shuld I put put my project in ? I'm a noob on honda-tech:'D
