im personally not too familiar with hondas and had some questions about building Honda motors. first one may be a little dumb, but im not entirely sure since ive only delt with chevys and rotaries.

when you go with new internals do you have to have them balanced? i would think so but not sure. and are they internally or externally balanced?

next question is when boosting a B18 at what levels do you need to have the engine sleeved? about how much does it run to have that done?

just sorta curious, thanks.

 

I would always recommend have the internals balanced. you can rev the **** out of a B18 so you want to make sure that everything is balanced. I am not sure what you mean by internal or externally balanced but the is no balance shaft on a B18 so everything is balanced by the particular weight of the parts.

As for the amount of boost a B18 will handle before getting sleeved I have Seen people run as much a 14 lbs and not have to much problem however the motor didn't last that long. if you are going to go throw the process of balancing the motor I would have it sleeved. It will save you alot of problems and money in the future. Plus a good sleeved block will last you a long time. Its kinda like building a house on sand or on a good cement foundation. Have a reputable shop do the at least the sleeve work.

 

im in cincinnati ohio.

i have a machine shop that has done great work for me in the past, but that was on chevy motors and i dont know if he knows much about hondas.

oh if its balanced by the weight of the parts its internally balanced then.

do you have a rough estament of what sleeving costs?

 

I am sure your machine shop does awesome work but sleeving a Honda block the right way is a very precise procedure. There is alot of setup that goes into machine the block to accept the sleeves and keep them from moving. I highly recommend having Justice racing In Maryland do the work for you. They specialize in Honda's and small engine and do some of the best work I have ever seen. The cost of shipping a block ground isnt that expensive. Give them a call and ask for Jim he is the owner.
