ok, i'm looking into getting a race car honda. now dont flame me, i know that hondasarent made to be racecars for the most part, but i was wondering what would be the best choice for me to make. i want a rally fast car with a b-series or ls engine that is bored to 2 liters

b20/vtec
(b20b w/b18 head)
C-RVtec
(b20z w/b18 head)
beighteen
(b20b w/b16 head)
CRVtec
(b20z w/b16 head)b18 overbored to 84mm
ls overbored to 84mm w/vtec head

notice that this will be going in a CRX most likely. tho i might even think about a h22 civic combo, though unlikely (more likely now to do a h23 with boost)

the best choice would be a b18c1 bored to 2 liters

If you can pull it off, a frankenstein CRV with a VTEC head boosted will be one fast son of a bitch...assuming it is in the right chassis.

get a GSR block get it sleeved and bored to 84.5mm and you have a 2 liter with oil squirters(non Vtec bottom ends don't have them)

edit: are we talking a streetable car or a hot rod class car?

ls_101

if u are looking for a car to put it in ive got a prelude rolling chassis----1995 fs for $600 pm me if ur interested----do a h23 block w/ sleeves and forged internals bored over and put an h22 head thats been ported.... and milled down on then boost it in a lude body w/ tube chassis

sherwood

it's gunna be in a crx with roll cage.
if at all possible a street legal car would be prefered.

for that it would mean me having to just overbore a b18 and put it in the car, right?

(i think the laws are that you can put a higher obd in a car, but not a lower one, correct?)

now presuming that i can pass smog it should ceck out ok, correct?

Provocateur

That is good chassis to put it in.

You are correct about the higher OBD.

It should be OK.

would this thing be able to hold a high- compression piston? like 11:1 or higher and not explode?

BoostedITR41

all motor I would go 86mm bore on a sleeved B18C. also smog is goin to be tough and a CRX is a very tight engine bay....I would look for a 92-95 hatch and make your life easy. mid 11 second daily driver turbos are not unheard of on the east coast and I believe their are a few on the west as well. if you are goin turbo and a street car I wouldn't go over 9.5:1....a good engine builder told me straight up that compression has nothin to do with turbo spool

sherwood

i might not even go boosted, i was just asking whats the highest comp ratio befor a 84mm bored b18 would start to see problems (high compression also menas more force on cylinder walls)

if i could find 84mm bore pistons at 12:1 compression it would mean that i could have a b"20"c with i'm guessing 200 whp and around 145 ft/lbs of torque and it wouldnt be a tax on the engine bay.

the crx is tight, but it's also alot lighter when stripped than a stripped hatch (tho this also means that i can have it be nearly the same weight as a stripped hatch with few essentials for those long drives to the track... ie radio)

the crx also has a much smaller coeff of drag (.25 i think)

i believe the hatch has a low coef, but not nearly as low as .25
I figure this crx built with 12:1 comp pistons and utned correctly with a nice Topend job will only cost me around 8 grand for everything minus install (1 grand topend job, 3 grand rebuild and boreing, 2-4 grand endinge, and i can find a crx for a few hundred if not below 2k)
