this would be in an any hatch.
im talking about with the k20 being customized in the car of course.
i think you would have to pay the same amount of money building a relieble street B20/vtec as swaping in a complete K20

b20vtech

b20vtec is okay for street......

saver

and k20 isnt your saying. im just asking cause i just want to do some more research about both motor swaps.
just keep it coming.

All said and done the K20 will cost you about $9000 to install into any 88 to 00 Civic.
A nicely built B20/vtec might cost you a lot less than that.

saver

anyone here has ever built a B20/vtec please tell me how much you have spent on it.

b20vtech

if u have the money then K20.....if u dont have the $$ then i suggest b20vtec.....

saver

the main reason im asking all this is cause i have seen fully built street B20/vtec making the same power as a stock k20 motor. and making the same price. well with my future dreams i want to do AUTOX. so wats worth it.

bmoua

id go with the k20 becuz its basically stock and its making the same numbers as a b20vtec...whats going to be more reliable...k20 of course its in its stock form...it always be more reliable

I think there is your answer, you have seen fully built b20v's making as much as pretty stock K20's.

Like they said before, if you have the cash then K20 if not then B20, but if your gonna spend all that money building the b20 you might as well save a little bit and buy k20. That seems to make the most sense imo.

itk

as much as I think a b20Vtec would be a nice engine..... considering that you have to swap the head for a vtec head compared to the stock k20 just means that the b20vtec will not be as reliable as a stock k20..... of course that all depends on your parts and on the driver.... but generaly if you rev the b20vtec too much (which the vtec head needs) on a stock block you will run into problems.

I say if you have the cash get the k20....if not build a b20..... just make sure you take your time with it and do it right the first time.

purepwayplaya

id go with B20 ive been hearing a lot of bad things about k20's after they are in matienancewise but if you have the money go for the k

kmotors having alot of oiling issues the oil pump is not quite up to par as with the bseries and as far as lsvtec being reliable my cousin has ls/vtech 11:3 compression over 50k on her and still strong and no problems just all depends who puts the motor together and what parts youu use

acydphryck

Here's my B20 VTEC setup:

I'm planning on daily driving this in my hatch sometime soon
I'll be running 91 octane too...so hopefully, she'll be happy

lol oiling issues at constant 9-10k yeah... but you wouldnt need to rev that high. its vtec not "vtech"

no where near 9k, yeah maybe if you are a baller and pay retail, and pay for the nicest parts.

Go k if you dont mind spending alittle more, and doing more work.

your breaking my ***** about one mis spelled word ,and if kmotors are not having oiling problems how come Jeff Evans of Evans tuning had a k motor and then took it out because of those issues and went back to bseries even on his all motor car ,dont get me wrong kmotors make badass power but at what expense ,the kinks have not been worked out yet

na200whp

oiling problems are not an issue under 8700 rpm on a k20 motor. trust me if they did honda would be replacing a ton of motors . a stock K would be my pick over a built b20v.

wytechoppin

hell NAW FOO B20 cant never LOSS!!!! get the striaght,,, lol i kid i kid... nah but deff a b20V my buddy has one on his 99 civic 2 dr.. and whooped a dude with a K series in a 95 civic. it acually could believe it honestly. but oh well

A mild B20 will run:

B20 Block $400
Rods an pistons $800
Bearings $100
B16 Head with a port job $1000ish
Springs and retianers $300
Camshafts $550-600
Header $700 minimum (RMF, SMSP, HYTECH, etc)
AEBS Intake manifold $150
Throttle Body $250ish
OEM Gaskets and belts ($500ish TB, Tensioner, Oil Pump, WP, Lower Gasket kit, headgasket, etc)

Then you have to factor in machine work, assmbly if you dont do it yourself.
Transmission $600ish (stock perfect B16 trans)
Clutch an flywheel $550

now i hope you have all the other things like starter, alternator, all sensors, etc.

Now if you already have a GSR or a B16, then you have the trans and other stuff covered you just need to buy and build the bottom end etc. if you have a D series, then your talking about buying all the stuff i have listed.

Should make around what mine made if built correctly 220-230whp

K20 Swap :
K20A2 $3500-4000
Mounts $550
KPRO $1000
Misc fuel lines ,etc $300-400
Header $500-700

should make what a stock Type-s makes with bolt ons, 190-200whp.

Your left wit ha STOCK motor, STOCK clutch, Stock everything, and prob about the same TQ as the B20vtec.

choice is up to you. depends what you want. you blow the B20 motor up, cheaper to fix, you pop a K20A2 block, may not be as cheap to find a replacement, or rebuild.

saver

damn yall thanks for all the posts. making a lot of proggress with a lot of back and forth believes. thats never ever going to end cause it all depends on the owner. ive acually heard about the oil pump being not as good as it should be. i even heard it from honda tuning magz. they had a build on therel. see all i want on a B20/vtec is having it relieble to the block. the non sleeved block is ganna put me to add sleeves to it. the oem ones just crack. i just heard that from a lot of ppl on here. thats the one thing im worried about. besides having the Bmotor inside a honda looks nice then a Kmotor i think. :}

0VtecKiDD

Read an learn more, Stock B20 sleeves are strong enough to hold 230whp, seen it, just pm Pr0Honda

dont go by what Honda Tuning says

acording to your totals
B20vtec = 5900.00 with no engine management or tuning and as you stated your also assuming they have other B stuff like an Alt , starter , mounts , ECT......

K20a2 = 6500.00 w/ Kpro witch has calibrations to run this setup more or less tuned

with the B motor you will need to be knowledgable enough to build it (well) or pay for that. the K swap doesnt require a complete rebuild. the other thing to consider is long term value. sure you can do the B motor for a little cheeper but down the road when you want more power the K has alot more to offer.

Stupid thread. I love people coming on here bench racing.....and I love the term "fully built." Explain to me your example of a "fully built" motor.

who ever told you b20V puts down same power as stock k20? you guys come on honda-tech and throw false information around. there are MANY variables on what can be done to an engine. a k20 is a POS until you BUILD it. b20 is a POS until you build it. and whats fully built to you guys that are saying b20 puts out the same power as k20? ITR pistons and ITR cams is fully built? lol thumbs down for you honda-tech bench bangers. go throw a k20 into your civic and let me smoke you
