CR-VTEC discussion

[CivSiGuy]

first, if you don't know what I'm talking about read www.crvtec.com

I'll get the topic/ discussion going.

So if I did the B20 block w/ B16A head would headers for a B16 fit the application and clear the motor ok?

I am thinking of building it and putting it into a 5th or 6th gen hatch.

Anyone with any CR-VTEC experiences?

[madtownhonda]

yes, they will fit fine


as for CRVTEC experience, I have none...ask me what you want and I will answer to the best of my ability

[CivSiGuy]

I love how we're all so technical in here

[VTEC_boi]

I don't know.

Maybe try B18C5 headers (JDM 4-1 or something else designed for it)

That guy Jay on ff-squad used JDM 4-1s on his CRVTEC and the seemed to clear the block ok.

peace
boi

screw the b16a header, i would much rather see a turbo manifold and a downpipe on the bitch!!!

[pvang31019]

any b-series header will clear the block, oil pan, and front crossmemeber(5th gen)....

But what about the turbo?

details details details....geez. hmmm... maybe we can use the opening for a huge exhaust gas recirculation system untill we pick up the snail?

[Phatwhippin_CRX]

Yeah any B series header SHOULD clear it........ but just to be safe, I'd get one for a B18c anyways....

As far as the actual CR-VTEC however, do you plan on de-stroking it with the B17a crank? Or no? You could either keep the shitty r/s ratio...OR I belive endyne will make custom lenmght high strenght rods to get you a near perfect r/s.... but it will cost ya...

Within the next month or so, I plan on buying an 88 CRX Si (can get it for 900 bucks ) ANd puttign a B20z in there....

After a few months (and lots of $$ spent on the B16 rex I already have) I'll eventually tap it for the oil line etc, and put a B16 head on. Chances are I'd see about the custom lenght endyne rods as well... just imagine a 2.1L CRVTEC with a near perfect r/s!? You could easily upgrade the valve train and rev it all to hell... or keep it low compression and slap an intercooled t3/t4 setup on it and blow some Vipers away! hehe

The b20z block is very turbo friendly

[CivSiGuy]

B17 crank (b16 if b17 unavailable), ITR cams, JE rods and pistons (11 or so compression), B20z block, B16 head, Skunk2 throttle body, DC Sports 4-1 for b18, GSR tranny (LS for turbo), JUN flywheel, yada yada yada

t3/t4 turbo w/ 8:1 compresson if you go turbo with it. Jackson Racing also builds superchargers for B20's as well.

[Phatwhippin_CRX]

hmm.......

See that's the thing I don't get. In my opinion, why de-stroke it? A B17a crank will put it roughly at 1.9L... why use the B20 block if you're not gonna put out at least 2.0L? It would be easier and less expensive to go LSVTEC otherwise....

The only real reason to use a B17a crank (as I am sure you know) is to improve the R/S ratio...

But it's not gonna make much more power than the LSVTEC setup, and it will cost more.... I figure keep it @ a 2.1L setup and get custom rods....endyne or probe racing. That way, you can easily get H22 power from a B block, instead of a glorified LSVTEC... and your handling will not be compromised at all....

As for turbo, the CRVTEC is absolutely a monster.

I'd rather stay away from superchargers, as a turbo is more my style

But yeah, a t3/t4 on low compression with an LS tranny would be insane.... imagine a 60 shot on it to spool the turbo? Can we say 10's? Don't doubt it.....

[madtownhonda]

I think I would rather turbo a b18c1 than a b20b or z...that's just me though

[Phatwhippin_CRX]

The B20z/b is MUCH more turbo friendly.... the block is much stronger (cylinder sleeving) and has lower compression....

the B20 is a much better choice for turbo than a B18c.....

[Rice-Rocketeer]

Not everyone is concerned with turbo's.

But that's what I love about the B20. Build it NA, Build it Fi, either way, it'll have gobs of torque and kick ass.

Check out those dyno charts, that's HP to THE WHEELS........!!!

With custom length rods, you can keep it a 2.1L beast...

Either go ALL OUT (bye bye streetability) and go all JUN and Toda internals...

But this is what I;d do....

Skunk2: Intake Manifold, Cams, Titanium Dual Valve srpings, retainers
Spoon Sports Cam gears
CTR pistons
Overbored TB
JDM 4-1 Header
Comptech exhaust
AEM CAI

then the mandatory ignition/fuel uprades...

easily 250+ to the wheels........ an all motor monster.
