I've seen/heard/smelled some baby farts that would make a grown man cry...but yes, she's pretty pig rich. Is it safe? HAHAHA, yeah. Could it use improvement to pick up a few more hp/tq? Yes...probably about another 10-15, MAYBE 20whp. My buddy dynoed 176whp on this tune on his B20/V setup, but he was running a stock TB and B16 cams. I've got a Skunk2 IM, Omni 68mm TB, GSR cams, and phenolic TB/IM spacers. Not that that would make much more of a difference, but with a solid tune, it'd probably be good for at least 15-20 more HP.
hmm i was debating going with a b20 block on instead of keeping my c1 but after this i think ill keep the c1 bore it a little and raise the comp.

I had originally suggested doing an 84mm GSR block, but everyone told me it'd need to be sleeved and his budget doesn't allow for that. I'd prefer a C1 block if it were me.
 
There are no ifs ands or buts about it. If you want a 2.0 B18C, you need to have it sleeved.

After doing my B20V build, and a milder 1.8 version of my build, I will take the extra displacement all day errday.
 
But at a certain point, displacement vs gross weight you won't be able to make use of the power correctly :)

I prefer dynamic displacement :)

I'll be honest, if I like how his turns out, I have been considering building one for my SMF car...or at least a B20 high CR. I got to thinking about the fact I'm about to spend a lot of money on a diff, and I'd be peaked out about 160whp with my SOHC.

i like to keep things N/A in being in the valley. Id love to be super charged though, turbo is just not my thing.

That might be a good decision id like to see which way you go on this. Would this change what class you run? I know nothing of SCCA.

Nah, I'm already in Street Mod, so not much will bump me aside from an LSX swap or too light lol.

Got the motor tore apart last night, everything looks great internally. Going to order everything for the block soon but I've got a couple of questions...

First off, rod bearings needs 2 green and 2 brown, and the mains need 3 yellow and 2 green. Should we use the next smaller bearing for a little looser bearing clearances? I know we discussed VTEC motors have a little looser tolerances, but want you guys' thoughts.

Next, I think we'll order this GE/Lightning MS VTEC kit with the headstuds, but would like to double check with you folks as well.
 
It's a cardinal sin according to Honda people, but I usually use ACL or Clevite bearings. The mains usually end up right around 0.0017"-0.002" with the rods at about 0.0015"-0.0017".

If you know what the current clearances are, just used the nominal bearing thicknesses based on color code (I think they are in the manual?), do the math, and go from there.

You can also mix and match colors as well within one step.

Also, I would order the 84.5 mm kit unless you don't plan to bore the block for a fresh surface.

Well he ordered all the stuff we need from Honda; bearings, oil pump, etc. I think he'd like to keep it 84mm to keep machining cost down, but the walls look superb. We haven't ordered the VTEC kit or pistons yet because we want a machine shop to double check them, but still shooting for 84mm.

So.....why are you replacing pistons? Going high comp?...and boy! OEM bearings ain't cheap, he could of save cash and spend it on a better CAMS, not unless he is budgeted for them already.
