Is it worth it to do a crv vtec with stock b20 block and stock b17 head?
I am thinking of putting this into my crx but i don't have a lot of money for pistons ,cams ,etc. So my question is would it be worth my time or should I just stay with my b17, and spend the money on it?

curt801

anyone?

stick with the b17 there great motors and seem to pull really hard with basic bolt ons. i know of people that are making 190 whp all motor and mildly built

curt801

anyone else?

without better (afermarket) pistons in the B20 I would not go that route.

keep your B17 bottom end until you can really do a B20 block correctly.

crvtec is great but it is unreliable, u said u don't want 2 spend that much so if you drp the crv you'll have to redo your valvetrain, springs, reatainers, valves, so u don't blow your head. and that's a must

stockSi00

b20 w/ b17 head will be a nice motor, very powerful but thats good advice stick with b17 blok till you can build the b20. my friend has a slapped together b20vtec
and it runs shitty but it's fast. stock bottom end,gsr cams 4dr2gtegs, so u can do it

This guy doesnt know what he is talking about.

I say you see how much $$ you actually have to spend, see how much the B20 block costs, the oil line, & adjustable cam gears & that is all you need. The stock b20/vtec will make you smile & is a better engine than the b17 in most aspects.

I recommend the b20/vtec

Yes, it's worth it if you do it right and build it.

Save your $ and do a CRVTEC when you can build it right. I've seen too many bad CRVTEC's as opposed to good ones because most people use a completely stock bottom end then rev to 9K all day long. The CRV bottom end was never designed for that kind of abuse, sure it'll make power but not for very long.

i am only planning on reving to 8200 or so.
because its not a built motor. would it be o.k then?
why cam gears?do the stock cams need to be adjusted?

u will definitely be better off building it, but they are strong as hell even with stock internals. try to get a block for under $800 and decide whether you are going to stay all motor or not. I know you have another post that says you will probably turbo it, that is not a bad idea with the lower compression of the b20, but you need a fluidyne radiator(probably no matter what you do with b20vtec) and a lot of head work(eventually some block work) if that is your plan and you want it to last for a wihle. the cam gears will help time the flow of the air for the larger displacement. you can take it up to redline, but be careful. what i did was build up my valvetrain first, because it doesn't matter what you do that is going to help with power no matter what your goal is, then put the b20 on then did the block work on the b20. lots of $, but huge #'s whp and wtq, most b20vtecs will put out more power than h22's, but you will invest some $

curt801

k thanks that is what i was looking for.

SicSi

go with the b20 man but it's gonna cost you$

curt801

what about just complete b20 no vtec? ia might try it out first just to see the change when i do get vtec.
yeah right when my vtec went out in my teg i hated it.

SicSi

i suppose if money is a issue but i think you're better off with the b17 then. i have a built b20vtec and it's great and all but it really doesn't start jammin till i hit vtec

singlecamrocket

off the line is so much better with the b20(displacement), yeah it pulls hard as hell once u hit vtec, but i can't get over the torque at low rpms, when i had my stock b20 on p&p head that was the biggest thing i noticed was the power off the line. i would go vtec, but a lot of people do just stay b20, here it gets great gas mileage

owen_the_soyboy

you can run a stock B20 nonvtec motor and then boost it and will likely be happier than a CRVTEC boosted (because that would cost more $$).

the stock B20 can handle enough boost (6 or 7 psi) to make you happy as ever.

Anyone that says stock b20 cant make power
or says that it wont last...
I had the motor for 10k miles b4 i sold it

The motor is still running fine to this day!

Compression tested and dyno'd the exact same #'s the day I built it, and the day I took it out of my car.


b20vtec will own any b17 w/ stock block

Stock JDM 2000 B20b bottom end (same as USDM B20Z)
B16 head w/ ITR cams
FPR and stock b16 ecu
2 1/4 exhaust w/ cat

Here is the dyno

and the car

curt801

nice car.

curt801

thanks for the info everyone i'll probably be selling some stuff to afford the b20. i found one for 750 complete. i'll post if i get it.
thanks again

yeah nice car and nice graph, but a B17A1 with CTR pistons and a set of good cams like Skunk2 Stage 1's will make about the same if not exactly the same numbers. seriously.... and for less money right?
ctr pistons, rings, pins = $300
sk2 stg1 cams, itr v.train = $600
-done-

curt801

true i probably won't do crv vtec tell i get the all the cash to do it right. i'll be happy with the b17 and boltons in the crx. it will be faster than my old car(00 si) so at least i am getting faster and thats all i won't for now.

Turbo Laser

a crvtec engine will be just as reliable as a crev engine.....it really all depends on how high you rev and how often you rev that high.
If you have a relatively stock rev limit it'll be 100% reliable.
I'd still probably take a B18b/B16/b17

curt801

still looking for b20 if any one has one or knows where i can get one let me know. thanks

curt801

bringing it back. what should i do?b20z with b17 head (both stock). i would have to sell parts to get b20z block(b17 shortblock, ys1 tranny 92 gsr grinds third, or parts and cash). keep b17 and put ctr pistons and cams in b17. possibly b17 with junkyard turbo. Keep b17 stock and save money for b20z block.what ever motor i would use a jdm b16 y1 cable tranny w/ lsd
