Hey, I'm building an LS/Vtec build as well...looking to bore the block out to 84 mm...did some research, here's the difference between the rods (because i made the mistake of buying the wrong rods)
The B18C has...
# Stroke: 87.2 mm (3.433")
# Rod Length: (5.430")
Shorter stroke, longer rod, higher revving.

The B18A/B has...
# Stroke: 89 mm
# Rod Length: (5.394")
Longer stroke, shorter rod, lower revving.

Got a sweet deal on some blox turbo cams, getting some tuner toyz ls rods, got the arp head studs, greddy turbo kit, golden eagle conversion kit...still need some parts, but if anyone has any good advice on some low comp pistons, i'm open to suggestions...

not sure if i can drop 3 g's on motor work...work my ***, but don't get paid well for it

Dang, I would've done 84 or 85mm honestly but whatever floats your boat.

Your headgasket would like to kick you in the poop shoot too.

TorganFM

Yeah because 2L blocks are so extreme.

boostedfab

when you go 84mm or 85 you only get one chance to break the block

go 82 if it breaks go 83 then go 84 dont want to waste it on the 1st try...

Looks good What is the setup gonna be?

Maybe you can make a super extreme 85mm block and all the cylinders can share compression. Like if one is low, it can just borrow from the other.

TorganFM

I understand the rationale, but it's just what I would have done if I were sleeving a block. 84mm gives you a couple chances for poor oiling and scuffed walls.

Stealth, exactly.
