Is a 2000 B20Z with 4k miles on it worth $2000? Theres a guy around my way selling one.

Steve

 

screw that. all you need is the longblock. check out hondamotorsonline, it's $790 for a b20

 

Yea but that $799 for a B20B not the B20Z and its also plus shipping probably with 50k miles on the motor also compared to 4k.

Steve

 

The block is the same for all of the new b20's, it doesn't matter, and the mileage is usually quite low. Hell, even with 50k on the motor it wouldn't make a difference. It's not like those CRV owners are known for racing, lol.

 

only the b20Z and the JDM b20b are the same the US B20B is wack compared to the other 2. Yea I agree with the part about the CRV owners probably not being hard on there car, but 4k is suck a low milage and it is the B20z so its one of the btter b20's. So do you think its worth it or would you just get a b20Z for 950 which I can get but the milage is more. It is still a B20Z though for $950

Steve

 

that's $799 for the b20b or the z, just specify and talk with Steve at hondamotorsonline.com and if he has one you'll get it for the same price...if he doesn't have one you'll still get it for the same price but have to wait for the next shippment. the B20 18,000 miles or less from(hondamotorsonline.com)

 

JDM b20b=USDM b20z

 

I paid $1000 cdn for mine with 59 000km on it. so that should give you a ball park.

 

For just the longblock, 2000 is to much.

 

how do you tell if its a jdm b20b and not a usdm b20b by just inspecting it?

 

I think the jdm just says b20b with no number afterwards. Also if the jdm b20b is identical to the usdm b20z, then it should have a knock sensor.

 

No big *** intake manifold ( I think)

 

its your money but i would not do that. the machine shop here says that BRAND NEW b20 blocks can come out of round (the cylinder bores) and usu. recommends a .025 overbore anyway.

are you going with aftermarket pistons and rings? if so, should not matter. for 1200 diff. btwn above quoted prices you can get a lot of shi- done:

overbore with hot tanking to clean up block ~120
JE or Arias pistons ~480
Crower rods (or others cheaper) ~600

see where i am going with this? well, that is what i did, and prob quite a few others too....now which choice would you go for?

 

well i was planning on just putting the motor in, but all I want is the haed to be redone with VALVE SPRING and RETAINERS, and up the ecu to a 8500 rev limit, but i would only take it to 8k. I dont want a VTEC head right now, i just want to play around with the straight B20 motor and my goal is a 13 sec all motor B20 nonvtec. Which isnt real hard if you know what to do and get tuning done.

Steve

 

i hear you, just remember those b20 blocks are famous for cylinder bore warpage which will be highlighted when you tune that mug for more power....

 

where did you hear this? I've never heard of this problem before.

 

this guy has no idea what hes talking about, b20 cylinder walls are thick as fawk...and as far as 2k for a b20 motor go ahead and buy it if you like being ***-raped, I can get b20b (jdm) complete long blocks with less than 20k on it for $750 but who cares all you need is the shortblock no one uses b20heads/trannys/etc...but thats in socal...good luck

 

well, you guys like to throw stuff and i wont in return - go ahead and be thick headed.

listen to what i said, not what you think i said : the cylinder bores tend to warp and seem to come that way many times on FACTORY FRESH motors.

this has NOTHING to do with how thick the metal is on the OUTSIDE of the bore

 

ok, but where did you hear this, just curious cause I've never heard of this before?

 

What all are you getting for the $2000. If it's just the stock motor then you need to see if you can get him to come off that price alot. If it came with the ls ecu, distributor, intake manifold, fuel rail, injectors, and a GSR Tranny then it might me worth closer to that. I wouldn't give more than $1300 for it personally. Also when you do get the car running, I don't see how your gonna raise the rev limiter and get more power out of that motor. If I'm not mistaken it makes more horsepower at 2k then it does at 6500. Just my two cents worth.

 

i have seen it myself on a b20b with 800 miles on it and mine (with more miles - about 30k) was as much as .012 out of round - the cylinder bores .

also Kurt Gordon who built bergenholz's first 9 sec. car told us to watch out on that as he had sen it and was at first steering clear of them

it prob has something to do with the rod-angle ratio which is not optimal like a b16a's and so big rpms or turbo boost prob exagerate the tendency

 

i raced my crv. 19.22 1/4
not bad for full interior+ some

 

No, for 2k you can buy a GSR block, and have it sleeved to 84mm. And you can run crazy boost on that with the right internals and tuning.

 

id never heard of the warping either. im getting a b20, im trying to get a b20z so i can guarantee myself the 9.6:1 cr. the jdm b20b motors, from what i hear, can come either 8.8:1 or 9.6:1 and you cant tell which is which short of pulling the head. and with cams,valvesprings, and retainers you can rev to 8.5k. look at the post here where the guy ran a low 13 on slicks with a b20 w/cams,springs, retainers and i/h/e. pretty sweet.

 

in a 5th gen civic hatch with a B20B swap, the right gearing and bolt ons and some slicks alone you should be able to run high 13s.

2000$ US for a B20Z longblock is insane! are you planning on rebuilding it?

also, for the guy who mentioned the "warpage" in B20B cylinders is right. when we tore my B20B apart it was absolutly spotless inside with no wear on the crank, pistons had no grime on them...looked like it might have had 10K KMs on it MAX, but when we went to bore/hone the cylinders, the bore size was different on the top/middle/bottom and inconsistent through out the cylinders.

I'm more leaned to believe that this problem is NOT due to the caracteristics of the engine...i.e. R/S ratio. Most likely they came from the factory that way.

a good machinest can fix that no prob though
