B18C4 .5 over-bore can it be done

Recommended Posts

I have taking the engine out of my MC2 to be repaired as the beast was burning oil alot , has done 224900 ml , the engine has been taking apart and they found out that the bores are burd and need re boring , No 4 cylinder was the worst and they said that the thing was ready to go bang on me , No 3 was badly carbon ed , No 2/1 were slightly bured .

They need to be over-bored to point 5 , they are unsure as to whether or not it safe to do this with the metal on the engine and uprate the pistons , they asked me if i knew but no i don't , so i ask you good people of civic5 to help me please .

Is this going to last long if over-bored to this size with the new size pistons in ?

The rest of the engine is spot on its had a total strip down , then if the bores can be uprated then the rest will be done as well uprated cams/valves/full polish the lot , so why buy another engine for when this one can be better.

Us ebay is the place to look mate , if you are going 0.5 mm over size that will be fine , you will need 81.5 mm pistons . If you raise the compression you are going to need the car mapping once you are done with the engine build or it will not last 5 mins . I use cp pistons .

Here is a link for you .

This bloke is selling cp pistons and if you look down the listing there are all the part numbers for all the pistons you need :

SC7011 81.50mm (+.020" Overbore) 9.0:1 (STANDARD REPLACEMENT)

SC7111 81.50mm (+.020" Overbore) 11.0:1 ( HIGHER COMP)

SC7116 81.50mm (+.020" Overbore) 12.5:1 (EVEN HIGHER COMP)
