hybrid: b20 and b16

[ah789454]

tell me wot so great about havin the b20b(97-crv engine) block and putting a b16 head on it.

[VTEChnique]

well BASICALLY..

B20 = low down torque (pulling power) with increased engine capacity (there's no replacement for displacement) but no top-end power.

B16A VTEC = Top end (High RPM) power with no bottom end torque.

B20 block + B16A VTEC head = Bottom-end torque AND top-end Power !!!

sounds like some1 has been reading hot4s :P

how much would it cost to do the aforementioned conversion?

sounds interesting :D me want

[KnfUzn]

hey ALLMTR how much does ur car weigh? sound fkn sweet...

[skoota]

me wants to put in my EK...

Actually, it sounds like someone knows what they are talking about. CRVTEC has been around quite a while now.

I read the article in Hot 4's tonight. The Perth guys made it sound like they invented Frank motors when, in fact, they were invented by a very good friend of mine about 6 years ago

690kg

Damn!! I saw those pbase photos of you lifting up the back of your car! :P:D

[KnfUzn]

fk me drunk! 690kg! my balls weigh more.... very nice dude... check this civic out, its a 86.... http://www.fortunecity.com/silverstone/brabham/205/

[A'PEXi]

690kg not bad....

[kleenex]

how much would it cost for the parts excluding the installation??
would it be better to do a b18 swap?

[SIKCVC]

I've been told many times, including from www.crvtec.com(i thik thats right) that the b18 bored to 2lt is a better option... since you will more than likly need to resleave the b20 due to the increased compression... am i right???

also i heard theres a **** load of effort in converting the b20 block to make it match up with the civic head. then you need to by a fwd gear box. This is just what i've read from the US forums. from what i gathered though the b18 bored out was just as quick and much easier/cheaper to do. $600 for the bore/resleave(providing your not going stupid with huge amounts of boost, if you decide to turbo) $900 for half decent 94mm pistons.

can anyone patch the holes i've left in that post please, i only know the basics of it all.

lol.....because some noob brings up the frankenstein (which just so happens to be in the latest edition hot4s), you think he knows what he is talking about??

doesn’t sound like he knows what he’s talking ‘bout to me :roll:

[tinkerbell]

teh price ranges from 2000 to 10'000

speed costs money - how fast you wanna go?

(also depends on whether you can build it yourself or whether you pay someone to...)

mate, you post is ALL holes!!! :oops:

[SIKCVC]

well please... if you know better fill the holes... I'm only regurgitating what i've read from the US guys who've been there done that.

[ALLMTR]

Tinkerbell is an AUSSIE guy who has been there and done that. Wait til I talk him into going K 8)

[tinkerbell]

no need to talk me into it Chuck - i just need some cashflow and i am there...

this time YOU are the guinea pig, :D

--

SIKCVC - the only reason a B18 would be prefered over a B20 if re-sleEving is the price.

AND there is NOT a ****load of effort in converting the block, you convert the HEAD to fit the block!

PLUS what the **** is a FWD gear box?!?!?

every Honda i have worked on has got one of THOSE!?!?

ALSO what the **** are 94mm pistons?!?!?

if YOU dont KNOW - DONT say!!!

Just a quick question to those that have done it, is the power gained from one of these crvtec conversions comparable to the stock power from a b16a with more torque down low, or is it more comparable to say the type-R engines?

i've heard that if done incorrectly, u can actually have less power than a b16?

i have more power than most type R's

110kw ATFW

plus i have a more 'usable' power band as a bonus ;)

Anything done incorrectly will reap poor results but a B20vtec should make more power and torque than a type R

[civex98]

roughly how much does a B20Z shortblock cost (I think that is what you need right? plus the B20Z is better than the B20K??) and any additional stuff that you would require (what exactly do you require?) cost to install a into vtir civic?

Would you require anything other than the shortblock and work done to it? or am i missing plenty of parts??? I know that you have to prepare the block for vtec as it orignally isn't (i think) but is that all the stuff that you'd need?

i've tried looking around, but crvtec.com seems to be down (or changed into a very unuseful site)...and i have taken a look at some of the US forums....

[ALLMTR]

Anywhere from 1000--2000 dollars for a short B20 motor

I dunno what the hell a B20K is????????

I have copied and pasted the below info from a thread in the tech section to save you from going to all the trouble of searching :

1) Head will need to drilled to allow for the different position of the dowels on a B20 as opposed to B16

2) Oil supply hole in VTEC head will need to be tapped and plugged at face surface

3) External oil feed line will need to be fitted. Usually "T" off oil pressure switch and run to fitting at rear of head adjacent to cyl 4

4) Pistons will need the inlet valve cutouts enlarged as the VTEC head runs a 33mm valve as opposed to 31mm on the B20 head

5) ARP head studs should be used

6) ARP rod bolts and closed and honed rods are HIGHLY recommended as you will be revving this motor a LOT higher than the bottom end was designed to

7) Ancillary items will have to be addressed due to the motors need for more air/fuel
