OK im a little confused....I know that ls/gsr have a block bridge or girdle whatever you wanna call it and I also know that a b20 has one. Does the b16a have a block girdle? In my haynes manual it is showing one for "VTEC models only" but thats not specific enough. I have heard that b16's dont have the bridge but can someone verify for sure? Reason i want to know is im working on putting my engine together from scratch and I know i didnt use or have a block girdle in there.

 

only b18c blocks have them, non-vtec and b16/b17 dont have them

 

called block gridle

z10 makes an after market one and theres a special one that is wider which covers all the main bearing

so im guessing that you can bolt a block girdle in a b16 from a b18c?

 

IF it can be done you need to get your main bores align-bored on an align boring machine i believe.

I believe you are wrong.

Some machine work is necessary to use a B18's girdle on a B16, I believe a couple of the bolt holes are different widths.

The only reason one should need to get an align bore done on their mains is if the main caps/saddles are warped, scoured, or you need to run a crank w/ bigger journals. Just throwing a girdle on the caps will not do any of these, so an align bore should not be needed.

If one of the B-series cranks uses a crank w/ bigger journals on the mains, THEN you could do an align bore to give you the bigger mains you need.

When I installed an Endyn girdle on my LS block, I was advised by the machine shop to hone the mains, as the girdle can twist things out of shape when torqued down and cause bearing problems. There have been threads discussing this before. Here is one: https://honda-tech.com/zerothread?id=162919

Well I stand corrected

I did not know that the girdle can cause the mains to flex some when torqued down. I figured having them dowel'd would be a good idea, but looks like an align bore would be a great idea, too.

 

align bore is needed sometimes, but ive seen cases where they just torqued down the block and everything was a go.

For example, my motor wouldnt turn over with the girdle torqued down so i got it bored and im kinda glad i did because it just turns over soo nice on the stand

But, another dude here just bolted his in and it turned over fine and now has 20,000 + miles on it

 

oh, and b16's have no need for a girdle. Stock bottem end good for 9000+

 

thanks for all your replies....I was just really hoping that my b16 wasnt missing the girdle but now I know it never had one
