ok, HT fellows, i did searched and try to grab as much info as i can for my built.
basically a normal stock sleeved built need the followings : (I had a complete B18c type R engine in my hand now)

b20 block
RS machine 84mm piston with choice of CR(i am choosing 11.5:1)
310cc at least injectors
ARP rod bolts
vtec kit
84mm head gasket

i can grab most of the thing easy in local but not the RS piston(living in Canada, but still, it's not hard)

then i recalled i did read some threads years ago about putting a b20 crank in a b18c5 something like that, (searched but did not come out anything)

question is : possible to do the crank swap only? if so, any modification needed? is it a bad idea or so.....? or i just go with the normal b20vtec built route?

thanks

 

if you put a b20b crank in a b18c5 you need to use the b20 rods as well. it's a fairly common thing for people to do for an oem stroker.

 

Look here, just did the B20/LS crank and rods into my gsr block

The b20vtec will give you more torque than just a b20/ls crank in your type r block, even if you bored out to 82mm, the extra displacement from the 84mm b20 block makes a bit of a difference. I bored my gsr block to 81.5 with the b20 crank and rods, and its noticable slower than my buddy's ride with a b20vtec.

 

all motor, after reading ur link, i assume this is not just not a swap crank, rod built?? better to just get a b20 block???

 

b20vtec will require a vtec conversion kit, you can get one from from Golden Eagle, but other than that, it would probably be easier and more beneficial to go b20vtec. Good luck

 

thanks,
by any chance you dyno your motor yet?

 

HEY vince it's NY the silver EF

no more K for u EH ?

b20 will be a good route just read that thread and do whatthose guys are doing to make big numbers

hey man, whatzup.

still debating going which way, honestly the B20 is a lot more cheaper than what i thought. but just the stock sleeves make me worry
