My wife want a little more pep out of her 2000 CR-V, being used to working on real engines, I'm looking for a little insight from the econo car/tuner/ricer crowd. I'm thinking a supercharger and some massive engine work is the only thing that might really get this boat moving. I've all ready strait-piped the exhaust with a high flow cat, minus the grapefruit launcher exhaust tip, and did a home-made mandrel-bent intake with a K&N cone. I've found an Intake and Exhaust Manifolds no problem (that boast some really exaggerated numbers), but I'm having a little trouble locking down Heads with higher flow numbers and better lift capabilites, Camshafts(preferrably higher lift durations, and overlapping lift cycles to increase scavaging, and Larger ID throttle Bodies, if the stocker doesn't flow enough with some basic port work and thinner blade. And please, if you think that a spoiler is neccisary on a Fwd car, or that stickers add FT/LB TQ, please do not waste my time.

 

you could always port and polish the stock head. your other option for higher a flowing head would be to add a vtec head, but thats a whole nother arena.

and ease up with the attitude there. your first post and you're already flinging the sterotypes.

 

As is.......

 

The CRV really is way too big for the B20B/Z, unfortunatly. That's why they use the K24A now. Any supercharger that will fit a B18A/B will also fit this engine.
This statement makes me think you are a domestic guy. Domestic guys are lucky, plenty of companies make high-flow aftermarket heads for domestic engines. We don't have that option, all we can do is port and polish or swap other factory heads, as previously mentioned.
Crower makes an excellent line of cams, the 404's would probably make you happy. 3/4 race cams. If you don't like a lopey idle, 403's are the next best thing with a good power boost but better street drivablility. As for the throttle body, there are a few aftermarket choices availible as long as you have the other mods done to make it worth it. That is assuming the B20B/Z throttle body is the same as the B18A/B unit, which it should be.

The B20B/Z is very easy to modify because it's a B series engine. There are lots and lots of junk availible for them.

BTW, a 2001 will have a B20Z. It is higher compression then the US B18B, and the same compression as the JDM B20B.

I thought VA beach had emissions tests too?

 

damn, after market on these things blows, guess thats what happens when you change engine designes every 2-3 years. Thanks for the help with the camshafts tho, 403's sound good. Its stupid to drive a vehicle built for the track on the street anyway. Just out of curiosity does putting the 16 heads on the 20 increase compression ratio? can't think of why you'd want to put heads from a smaller engine ont a larger one.....figured it'd be vise versa, but it seems everything with these econo cars are ass backwards anyway. Thanks for the pointers...anyone else?

p.s. as far as I've seen, inspections are visual only.

 

by 16 i assume you're talking about the b16? and yes that would increase compression but by only a small amount. that would also require some machining to the head to fit properly.

 

Head, singular. Honda guys only get one.

The B16A head really won't change the compression ratio, but if you reenforce the bottom end a bit to allow it to rev safely, horsepower will jump nicely with the addition of VTEC present in the 1.6l B16A head. Other mods are required to even get it on though.

Mind you, the B20Z uses a head that came out in '89 as a 90 model in the Acura Integra (B18A). It's based on the ZC head which came out around '84 in Japan, '85 (as an 86 model) in the US. It's not that new.

 

The b16 head will increase compression ratio, but not by enough that it would be worth it for the CR. However, the B16 is a VTEC head, which means three things:

Better cams

Much better airflow

Huge aftermarket

 

My family has a CRV so I thought this persons crv funny but you might be interested in this turbo setup
