The B20VTEC discussion thread

[90LAN]

what about labour to assemble motor ?
alot of ppl on here will not be doing the work them selves

what would be the average cost for a average b20 assembly with all parts provided
for a basic build?

rebuild parts will cost a bit more than what you quoted on the basis of prices traders are sellign atm

you also forgot to mention b20 conversion kit too

[GSi_PSi]

A Basic B20 will cost you around 4 grand . Ive been in B18CRs and now they feel a bit weak, when vtec comes on its not really as much noticable compared to B20. It actually pins you back to your seat when it kicks in.

Sam did that include labour to R&R the package or just the engine itself?

[Chr1s]

Labour depends where you go,

Some people charge 1k, some more, some less..You should speak to someone you can trust and at the end of the day, if you trust them, don't you think its worth the extra $200 to pay them? or if they're cheaper, even better!

Sam got taken care of with his build, didn't you Sam :P..

so 4 k all up running

so why arnt people doing more b20s to get 120kw atws

bargain performace if you ask me

[tinkerbell]

if you have a VTiR integra already, it is more like 2000 all up "running"...

this is what you'd probably need:

re-use the B18C head
B20B8 block
VTEC water pump
B18C timing belt
B20B head gasket
ARP head studs
ARP rod bolts
oil line and fittings
head work (dowels/plug/surface)
piston relief work
PCV system (fittings/hoses/can)
Coolant hoses
VRS gasket kit

but that wont make 120kW, even after you can control it (ECU) and tune it...

you will need this sort of stuff to get it really going well:

Performance header
Larger exhaust
Air filter or air intake
ITR camshafts (or larger)
ITR valve springs
ITR intake manifold
Larger throttle body
Lightened flywheel
Heavy duty clutch
Adjustable cam gears
Adjustable fuel regulator
Upgraded fuel pump
Oil cooler
ITR gearbox & LSD

man for sure b20vtec will have more pull, B18CR is quick motor with basic IHE, im our certain you cant get the b18cr motor with ur current setup.

H22a motor pulls lyk i mother f****, does that mean its faster?

You would need to change the gearbox if u wana beat the b18cR, thats another 1.5-2k

I know this thread is about B20VTEC but theres seems to be a lot of knowledgeable people here.

I was wondering if doing a budget B20Z non-vtec conversion on an eg civic (fuel injected) is worthwhile - especially for the economically disadvantaged

Coming from a D15B7, a B20Z would give me an additional 30kw/45nm.

The engines are relatively cheap but is the conversion as simple as a B16 or B18?
Would I be able to use the gearbox and ecu from CRV to minimise cost?

you would need all b series parts, u need a b16\18 gearbox

so really not that cheap after all
and labour cost too

but gsi psi done it with around 4k

care to share why so cheap to make 120kw?

not worthwhile IMO

Coming from a D15B7, a B20Z would give me an additional 30kw/45nm.

yes, but a B16A would also be a relatively big increase

almost exactly the same. (they are the same family of engines)

Would I be able to use the gearbox and ecu from CRV to minimise cost?

this *might* minimise costs, but will also minimise performance

so my stance would be that if you are doing a whole engine bay conversion, may as well do it with B16A out of a EG Civic half-cut

[GSi_PSi]

i actually done it with less. Like 3 grand, i already had some parts like the gearbox,clutch,flywheel. etc
My setup is the most basic with standard B16a intake manifold, B16a 60mm throttle body, i even had my stock airbox when they dynoed it and i made 121.5kw atw.
I now have my RMF headers, Fujita CAI, im going to be adding ITR intake manifold, 68mm throttle body and ITR Camshafts. Im hoping for at least 10-15kw gain with all these mods on top of my 121.5kw atw..
Zeforce Stock B20 with VTiR head only good bolt ons made 132kw.

Dreamshifter -
Hell yeah go for it man, my mate put in a standard B20 no vtec in his gsi it has pretty good increase. Just remember gearbox (no you cant use CRV its 4wd), computer is going to the ones costing the most. The B20 engine itself is around like 300 from the wreckers. I know of people in the U.S getting low 14's with ITR gearbox in their EG with a B20 no vtec.
