could someone explain to me what this is and what it does, ive been reading so much about how it could increase reliability on a built engine?

 

From Katman

 

b18c comes stock with these things, b16's sadly, doesn't. i wonder why that is. anyone care to explain?

 

Lower end engine not expected to perform like the C's.

 

B16A do not have one, but they still turn high RPM's.....They don't NEED one due to their much more favorable R/S ratio. Tho the B16B do have one, but a B16B is just a de-stroked B18C5.

B18C1 or B18C5 have a not as favorable R/S ratio as the B16's they need alittle extra help from the girdle to keep vibrations down.

so back to the question, exactly what does it do at high rpm's? does it stablize the crank?

Instead of one set of bearings going bad faster than the others, having a girdle will help distribute the loads. Block girdle causes the bearings to wear more evenly.

 

The D series engines have a better block girdle then the B's that come with them.

 

so would havin a block gurdle help no matter what mods you have on your mtor or would you guys just recommend it for highly built motors?

 

'help' in terms of performance?
IMO its more for durability.
Evens out the loads thereforeth
bearing set will last longer

Most say you will need the girdle if you plan of revving above 8500 rpm.
I dont think its really needed unless your setup is tuned to make increasing
power in that range, or if you have a long gear and you want to shift
that high so the drop in rpm wont be below torque.
