Before you guys flame me, I have done my best to research this on my own, but still have a few unanswered questions. I have decided to go B20 VTEC and am selling my GSR block + stuff. Do I still use GSR head studs even with a B16 head? In the "reliable LS/VTEC build," he uses a GSR head and an LS block, so I'm not sure whether or not these studs still apply to my build. Also, will I need to replace the B20Z rod bolts? I know that they're weak on the LS blocks, but are they the same situation with B20s as well? And last but not least, I plan on using a block girdle and replacing the 6 torque-to-yield bolts that need to come out to do so. Do I need to use longer bolts, or will the stock CRV bolts still work?

ARP ROD BOLTS are a MUST (but I can't remember if there is a dif size to use on B20 rods.)

Use ARP 208-4306 for head studs (GSR uses 208-4303)

Dunno on the block girdle. Call up Endyn for your part and ask Larry about what to do about ARP bolts for it.

Good luck.

I only want to replace these if I have to... are these bolts as weak as the LS bolts or are they decent like GSR rod bolts?

 

They are weak. They are probally the number one issue with b20s.

was there an issue with the head gaskets in the b20/vtec kit? a lot of people say not to use them and i was wondering why...

if so, has the problem been corrected?

 

all these guys that say there is a problem with the gasket we use never used our kit. we have had no problems with anyone that has tried our kit. i get calls all the time saying i got the wrong gasket, you sent me a vtec gasket, i tell them the same thing all the time to use it trust me and they do and guess what no leaks no complaint's.

 

Please note that the only difference between a B20Vtec build and an LSVtec build is the size of the headgasket.....the B20 and LS blocks are the same size and share the same rods, crank, ect. The only real difference is the size of the pistons, (and the style of sleeves on the B20)

Follow the LSVtec build thread and just use a B20 or +84mm headgasket

I'm fairly sure they're weak, I'd pay for it.

just to clarify....the OEM b20 head gasket needs modification? and the golden eagle b20 head gasket already has the modification?

and ours is ready to go here is a link of how we do it http://www.lightningmotorsport...t.pdf

 

The Golden Eagle kit is very good but I don't like the 84mm headgaskets they use. I am personally running one and have not had a problem but I believe that they are an 81mm recut to 84mm, in other words less seal compared to a moddified B20 gasket. If your going for a high compression B20 then I would recommend an aftermarket gasket.
