Are there any aftermarket block girdles besides the z10 girdle, preferably one that was completely bolt on including main cap bolts? Also If I was going to get the z10 girdle would I have to have anything machined to fit? I have a b20z fully built and I will be revving to 8,000rpms with my crower 404's so I definitely need a girdle just not sure on which to get. I need help asap.

My old B20 block (sold to a friend) and he resleeved it and built it up from scratch, using the Z10 girdle. No machining needed. Just dyno'd 204 to the wheels with a Y21, Hondata, old-skool DC 4-2-1 header, and GReddy SP exhaust. Haven't really seen any other girdles except for the stock GSR one, and that one you do have to modify to fit.

You could possible use a gsr girdle if you used the gsr main caps also.There was a post about a new girdle that came out but it was awhile back.Best thing to do is check the archives.

I found it for you bro.

If you only plan on revving to 8k rpm, then you don't need a block girdle. The stock bottom end is good to 8.5k with the addition of ARP rod bolts.

But if you have your heart set on a block girdle, then try out the GSR/ITR girdle. Same **** has to be done to make it work though, compared to the Z10 girdle.

yeah, i know..but its nice to have so my bearings wear evenly because i rev to 8k everyday! ..and i was planing on getting Jun3's too..soo, thats about 9k+...
oh yeah..my heart is still set even without a job! damn heart likes to get stuck on things... <

Like I said, if you only plan on reving to 8k, there is no need for a girdle. I added some ARP rod bolts for insurance on my LSVTEC...and I have numerous friends with these motors. One friend has had his motor for 2years and he takes it to 8500rpm every day, with no girdle and stock rod bolts.

i would add the girdle. it will take the some of the pressure from the crank and the bearings, and most people dont think about this but 8000 rpm is already extremely high for a motor with a stock rev limit of about 7rpm. get it and rev all you want all day everyday lol without worries.

what the hell is the girdle for

IMO... I wouldnt use the GSR main caps or that girdle. Why? Cuz the main caps wont match up perfectly to the b20.

I have had my b20/vtec for 40k now... stock bottomend. 8400 rpms all day long. Drag strip, circuit racing, & God forbid... daily driven.

wow thats good..ive only had mine for 11k...
you dont use the GSR caps..your suppose to mill-down the center of the girdle to match the B20's caps..then bolt it up with GSR cap bolts....!

yesterday i mis-shifted my crvtec, stock bottom end with ITR cams and stock b16 valvetrain, i rev'd to over 10k... went from topping out 4th misshifted into 3rd.

Car runs fine, no problems.... i rev to 8200 all the time, i dunno what a girdle would do for me.

dang you lucky that you didnt float a valve..... jeez. Mad props tho for seeing how high the B20 bottom end can go!!!

yeah i miss-shifted mine to 9.2k+ because damn old tranny wouldnt go into gear..but it still runs fine..!

yup damn the old trannies, ******* 5th is way the hell over.

HAHA I’ve done the same **** too! It was when I first got my 99 5 speed awd, I was going in 4th and miss shifted and put it into 3rd. Scared tf outa me and I’m blessed it didn’t blow up or anything haha.
