crv b20/ vtec

[stevh0]

hey guys

i am thinking of buying me a crv ,
main ideas would be the b16 head on the b20b , just for a little more oomph..

has anybody done it ? is it viable ?


i would imagine a 200-220hp crv would go really well .

any thoughts ?

[sleeksilver]

CR-VTEC.

Its been discussed a lot here, do a search.

I would imagine that the B18 GSR head would flow better than the B16 though. I wouldn't expect 220HP.

[stevh0]

its strange ..

in south africa we never got the b18c's , just the b16.

i normal b20 with b16 head - stock no cams makes around 190 - 200hp


a mate of mine has a b20/vtec civic making around 160kw (220hp)

so i suppose it very easy getting decent power out of the car .

but would it be drivable?


btw , thanx for the speedy reply .. yeah i should of searched 1st ..

my bad

My only caution is what how you modify the engine. You may gain in horsepower but loose torque. The CR-V doesn't have much to spare in that department.

[stevh0]

yeah i guess it needs the torque to lug the weight around

[sgtsandman]

The problem is that Honda has pretty much tweeked all the horsepower it could out of the engine without losing reliability and/or torque.

There are some who have went to turbo chargers but you have to be careful there too. The engine wasn't designed for compressed air so won't take too much boost before a cylinder wall fails. Turbos are nothing but trouble anyway in my opinion.

[stevh0]

also arb , there are a lot of arguements about the b20 engine . i have heard alot of rumours about the sleeves being so thing . but then other ppl say the b20 loves boost.


there is a guy in the Honda racing club of south africa running around with a 500hp b20 vtec civic , running 11's

so i guess if its built properly it will last but most ppl end up taking short cuts and fail hopelessly in that regard of building a reliable daily runner .


but then again , most b20 turbo vtec engine and a 16psi make around 210wheel kilowatt *290hp ...

sure would be fun in a crv tho

Comptech headers give more horsepower AND torque

Hi man... i am also from South Africa but now live in Australia.

I have a 2000 b20 crv, and dont listen to what people say about weak sleeves and shit, i mean yeah they are a little thinner than the b18b/a block, but you can easily run under 10psi with a reliable tune... I first decided to go turbo but after summing up all the parts and work it would have cost me too much, so i decided to go with Jackson Racings supercharger for the crv.

Now i have a couple of things to tell you,

1.) the first being that JR does not make the blower for the crv anymore, but the one for the Integra LS slaps right on with not too much modding... their web site is supercharger.com i think.

2.) if you decide to go turbo i really recomend you leave the engine "non vtec" for that little extra reliability, as crvtec turbo generally requires forged sleeves and internals to be reliable, because think about it, vtec is for top end like 7000 and above, the stock b20 block is not too comfortable with boost and high reving. A simple turbo kit around 8-10psi, skunk 2 intake manifold, maybe some porting, and a good reliable tune (hondata s100 or s200 preferably) with 550 injectors and a walbro pump and you can make 250-280 hp no probs on the b20.

3.) another few problems you might have with the b20 is not the engine but the crv... The crv dont like to be pushed too hard on the dyno, so when you tune it i suggest doing a street tune then atleast 1-2 dyno pulls, you may even find it better to dissconect the rear drive system so its only fwd for the dyno, also try bringing the timing down a little, you dont want any knocking at all with the B20 and deffinatly no fuel below 93 octane...

As i said i chose to go with the JR supercharger, ported and set at 10psi, i now run it with 550 injectors, 255 fuel pump, kamakazi 2.5" headers, with custom 2.5" exhaust, low heat plugs, hondata s100 tune, and best of all a custom made top mount intercooler from a subaru forrester sti... i was sitting on 218hp and 203tq before the custom intercooler, i can imagine somewhere near 240 now. dam is it fun...

well i hope this info helps, its from my experience with the beast that is the 1st gen CRV......

Oh and forgot to mention that if you choose to go with the supercharger and your not enjoying it, you can always slap the vtec head on then, as it is probably a bit more reliable with supercharger, that is if you keep within the stock rev limits...

enjoy

This will give you an idea on how a crv-tec set up would sound and run, but add about 1500 pounds and you would probably run high 13's on drag radials N/A if you had a 5 speed, thats good enough for some stock ls1 spanking

This was a budget built B20B that has eagle h beam rods, arias 10:5 cr pistons, stock 16 head, blox intake and port matched tb, on a direct port 150 shot from NX, tuned on hondata s300 by st00pid. as you can see in this vid there was some stuff that needed to be worked out like the damn fried clutch
b20 hatch on nitrous dyno and 1/4 mile time

but in this video the car ran its best, after this the car was built for an SFWD setup on boost making 850whp with a gt4294r full-race intake manifold, full race turbo mani with twin 44mm wastegate setup, 4 in down pipe, motec, aem ems, and is now for sale. but none the less here is its best run on nitrous and it did great on motor too...
just for fun here is an all motor pass against an srt4 with a bigger snail and a nitrous run against some 11 second station wagon! 11.20@125 honda civic hb
