b20vtec question

[genesis]

Just wondering if anyone knows whether the standard b20z crankshaft is strong enough to handle stage 1 NA revs?

[McChook]

Never had a problem with one before. Would be a good idea to get the harmonics harmonicing perfect

[BLKCRX]

try looking at the b20b crank, or a b18c7 crank... only thing is that will cost you $2500 for jsut the crank.

iv got a b20b crank for sale if you need one.

whats the difference between the b20z, b20b and b18c7 cranks?

[TODA AU]

Stroke & counter weights...
That’s why the B18C7 (Type R crank) is the pick of the bunch…
Email me if you need one…

[tinkerbell]

there is NO difference between B20B and B20Z crank besides the fact that B20Z = USDM

[tinkerbell]

oh B20B = B18B crank too!!!

BTW - my stock B20B crank is good for 120kW ATW... NA

[McChook]

The B20b crank needs a balance, but once balanced, have seen one at NA 200fwhp.

The B18 crank in the race car has 200fwhp with the standard B18 crank

[tinkerbell]

the race car is a B18B?

i hoep we are comparing apples to apples?

[McChook]

The race car is a stroked B18 now I think about it, so not 100% on what crank it uses

The B20 was an american All Motor drag car built here by an american guy, then shipped to america. It was in a Gen 2 CRX
