I'd like to reinforce the bottom end of my build with en Endyn or KMS girdle, GSR oil pickup, GSR windage tray and Moroso steel oil pan. I was told by Endyn that I could use the B18 main caps with their girdle (no dowel machining as would be necessary with the GSR/Type R girdle plus align boring) as long as I get GSR/Type R main cap bolts which are longer than the LS main cap bolts.

Instead of looking for used GSR/Type R main bolts or buying new OEM bolts, I would like to use the ARP main studs and just want to make sure I should be buying the GSR ones, #208-5403. Also, please tell me if what I am planning is reasonable, good, bad, worth it, not worth it, etc, and if the parts I need for this mod are complete.

Since I am not an engine builder, if someone can explain why the GSR/Type R girdle will not work with the LS main caps without machining for the dowels and why if I use GSR/Type R main caps requires an align bore, I would really appreciate it

 

If your going whith the crank girdle use ITR/GS-R main studs or bolts.

You can use LS main caps but they need to be machined so the girdle will sit flush. Some will say have it line honed but I never did and no problems with clearence. Just my 0.02. The dowels are there for safty so the girdle doesn't move. The girdle goes into the 2 and 4 mains in GS-R/ITRs but LS do not have the provision for them so can use the main bolts with dowels on all 6 or just 2 and 4 again.

If you use the GS-R/ITR mains you have to have it line honed because there not all the same piece meaning all main caps are not created equal. Thats reason why we have different bearing sizes. Even when your block was built in the first place it was line honed and finished off with correctly sized bearings.

I like the idea of reusing my LS main caps which has perfect clearance with my crank. If I understand correctly, since the girdle goes on top of the main caps, the machining is to the top of the main caps which doesn't affect the inside of the mains where the bearings go right?

Can you break this down even more for me because I'm still missing something. If I use dowels, then I need GSR/ITR mains right? If I use my LS mains, then I use the girdle without dowels right?

This I understand. So if I use a GSR/ITR girdle, then I don't need and aftermarket girdle. I only have to machine my LS mains so the girdle sits flush.

Please let me know if I've got it straight

 

Girdle

 

There is a post from a few years ago let me search some more its been years. The dowels go where the main bolts go in both the girdle and the main caps. Making it pretty much one complete piece instead of parts set on top of each other. They just need to mill # 2 and 4 caps just a touch and 3 needs to be taken down quite a bit but its all to make it sit flush. Dont forget you will also need the GS-R oil pick up and oil pan.

by B18 do you mean LS or GSR/TYPE R?

LS

 

from endyns pic of the girdle it looks like you can use ls mains. but i would still have the caps modded to accept the dowels. it just seems kinda pointless to do it without them.

as far as which studs to use i dont know. i guess go by what endyn says and pick up some arps for a gsr.
