b20 vs b18c stroker kit

[amant02]

I say buy a b20 block, vtec conversion kit, new bearings, vrs kit..ect, arp b18c rod bolts and head studs, rs machine 84.5 type r pistons and rings.

Send your cylinder head, b20 block and your b18c crank to a machine shop and have the crank linished, block resurfaced and bored to suit new pistons and new pistons fitted to b18c rods.

When you get the block back reassemble engine with your new parts, i suggest buying an aftermarket girdle for the b20 main caps or reuse your b18c girdle on the b20 block but you will have to use the b18c main caps and get the machine shop to allign hone b18c main caps to the b20 block...do the cheaper option out of the two. This setup should give you a b20 with oem reliabilty

Also while your cylinder head is being serviced i would advise you ugrade your valvetrain to suit aggresive cams if you decide to upgrade later on.

Whats a gridle? When i google it its womens apparel?

i used to have b20... i loved it. go b20 cheaper!

Girdle is a brace which reinforces the main caps. The b18c is the only b series with a girdle. Search b18c girdle.

The girdle wont do shit, if your cylinder wall is not even rounded and constantly see's 8,000rpm on a hot day with no tune

the only thing unreliable about the b20 is the cylinder walls........in my experience some b20's have the edges slightly thinner than the whole circumference of the bore,
not sure if this is some bad batch of them but these are the ones that have detonated in my experience

How can you say a girdle wont do shit when it is designed to stabilize the crankshaft at high rpm to stop the block from twisting which helps keep the cylinder walls straight. I think when you know a block has thin cylinder walls it would be nice to make sure they stay straight at 8000+rpm.

I always thought that the block girdle was designed to keep the bearings at an even wear rate. Fair enough, the block girdle might help, but both b20s i seen blow up had
block girdles installed still ended up cracking a sleeve. I have photos of the bore on these b20's when they were built and from the pixels you can tell the bore is not evenly round
throughout.... the b20 i had installed in my integra had the bore evenly round and thick throughout the whole circumference, i guess honda is not perfect.

how can you say that bout Hondas F u lol

If the cylinder walls on b20s are as bad as you say and the OP gets a B20 block with low kms and the cylinder walls are not really worn you can get away with std size pistons and just a hone so you can keep that extra .5mm of cylinder wall which is nothing really.

ive gone 85mm on mine haha with the stock sleeves
doesn't look that bad

phuc dat

[SLOBRO]

what's wrong haha
