ive read this board for a couple days now and i noticed everyone has a b18b turbo. do you guys prefer the b18b over the b20b or b20z?

 

b20b is the poo poo you can make some nice torque figures and hp but the rev ragne is week. excellent for street car. I will stick to my GSR bored out.

 

I bought by b18b simply because they are more abundant and cheaper.......i tried getting a b20 but only a few places had them and if they did have them they were expensive......from my experience the same price for a b20 i could get an LS sleeved and bored out to 84mm.....maybe in other places you can get them cheaper...and then there is always people that come across really good deals....but not me

 

yeah it kinda sucks b20b/z usually go for 1000 most places. and b18b you canget for like 100 bucks + 700 bucks to get it sleeves and 800 you got your self same motor

 

oohhhhh, could have gone 86mm.......but i agree, ls blocks are simply cheaper.

 

availability and price..

 

yep.. i love the fact that i can replace my whole motor for around 300-400 bucks..

 

if you bore the b18b to 84mm to match the specs of the b20z/b, will it match the torque and hp of the b20b/z? the b20z starts off with more torque and hp than the b18b, thats why im interested in it for FI. but if i can get a b18b and bore it out to 84mm producing the same numbers, well, whoo hoo! let me know. thanks!

 

yes it would produce the same numbers with the factory b20 pistons... once you bore it out it is essentially the same motor

 

and b18b you canget for like 100 bucks


I want one of those!!! How much should I pay for one with trans??

 

hell yeah, i bought 2 for 400 bucks here in TX, still a living motor fully built with a turbo on it... now it resides in a 92 HB kickin some domesic azz.

availabilty is good
can upgrade to make some serious HP figures
dont have to talk about (man my VTEC isnt kickin in) i here that here a lot from peeps with swaps.
torquey
room for improvement

etc etc

 

dam where do you guys find b18b's so cheap. all i see around here are just bareblocks for ~300.

 

what cars can you do a straight-up swap with? I.E. i have a 1999 civic si. Could i just drop in a new engine and use my existing tranny if i wanted to do so? I guess if i ever blow my engine i could get a b18b block instead of paying to fix my b16 block, right?

is the b18b a 1.8 and the b20 a 2.0? if they are, wouldnt the b20 have the advantage? and yea, where do you guys get your b18b engines from? ive never seen one for like 300 or 400 bucks.

could you bore a b20 to 2.2L? or close to it. would the cylinder walls be too small then?

 

just like these guys said... i like it cuz it came with my car. haha more torque... more boost.

 

yeah b18 is 1.8, b20 is 2.0. b20 is essentially a b18 bored out to 84mm so, logically if you buy a b18, resleeve it and bore it to 84mm, you have two litre (or actually just under)

No you can't bore out a b20 to 2.2 because you would have no cylinder sleeve left. Cool thing is though, that the two engines are basically the same on the outside so you can switch between the two (say if you blow one up) without changing manifolds or anything else.
