what should i do? should i put a b20b in my ek or should i put a jdm b16 g2
need to know what would be a faster swap? if i get b20 i will not do a b20 vtec just keep it a b20b

SkoundrelUSA

B20 with a B16, ITR, or CTR trans

***** 1.6 vtak

acura1808

yeah but the thing is that i don't want to do a b20 vtec if i get the b20 i will just do bolt ons or i will do b20 turbo

klungemonger

Tough call...if it was a B20Z (146hp) I would say go that route, but a B20B is giving up 34hp to the B16. A B16 tranny will help the B20 launch crazy hard but top speed in each gear will be low and you'll get irritated driving at 4500rpms on the freeway. Unless you don't care much about that...

If you're staying bone stock, either B20Z or B16 but I'd skip the B20B. Although torque is good it's actually 1hp less than a D16Y8.

B20b=125 hp @ 5500; 133 tq @4500
B16a2=160 hp @ 7600; 111 tq @ 8200

Personally, I would probably do the B20 because of the fact that you not only have quite a bit more torque, but it is available at a much lower rpm. Plus you may be able to pick up a vtec head in the future if you change your mind.

yeah that is true it is just b20z are really hard to find i just sold my jdm integra and it had a lsvtec i wanted to go a safer route so i think i should pick up a b16 do u know what kind of times i can run with a b16 at the trck

read what i typed foo

I said a B20 (as in the engine) with a B16/ITR/CTR TRANSMISSION! HAS NOTHING TO DO WITH A VTEC HEAD!

acura1808

yeah i can get that set up b20b with a jdm b16 tranny for 1100

I'm just getting ready to install a JDM B16 into my 98 hatch, so I don't have any times available yet, I'm sure you can find them from someone. Admittedly they don't put down incredible numbers stock, there is something to be said for displacement. But I put a modded all-motor B16 into a friends EK hatch and it was real fun to drive. They seem to respond well to basic mods. It had ITR cams, old Skunk2 manifold, and ITR 4-1 header and was tuned to 155whp.

If you do plan to turbo, the B16 is not a bad platform either and despite the higher compression I believe it is safer to boost stock than a stock B20 due to the geometry of the rotating assembly and better sleeves.

do u know if the jdm ls motor is about the same as the b20b????

Can handle the boost a little more safely. 142hp and 124tq I think.

acura1808

do u think that would be a better bet to do a ls then b20 because i think the ls would beat the b20 stock motor to stock motor

Budget Racer

Keep in mind a B20 cant be smogged unless your from BFE where they don't care. It is considered a light truck/Suv motor.

Get a B18b1 LS motor and turbo that mabey.

SR20S13

get a B16 they quicker stock and well its got MADDD VTACKKKKKKKKKKKKKKK, but joking aside i'd much rather have that free-reving abilty of the B16 and well i'd rather boost a B16 then a B20b becuase those are some weak *** motors

smoked_out_cx

i would do some research before saying a b20b is a weak motor. A b20 with a b16 or gsr tranny would be breaking off a b16 all day long.

klungemonger

When he says "weak" he doesn't mean it won't go anywhere or doesn't make power, just that it's historically more breakage prone than a B16 when pushed to the limit. Although I might argue that with a B20B even with B16 trans it has so little top end that once the B16 got into the band it wouldn't be getting "broke off all day long."
I had an LS w/GSR tranny, it was good fun and pulled good from down low, but would definitely have been served by my buddy's afore-mentioned lightly modded B16 in an identical hatch.

Why wouldnt you go with a Vtec head?

Stock? Mid 15 if you can drive.

Haha no. The rotating assembly is identical to that of the LS motors. They take boost all day long. As far as the sleeves go that is just a tuning issue. Tune your car correctly and you will have no sleeve issues.

Please explain why the B20 is a weak *** engine?

SkoundrelUSA

I wouldn't say its weak as in it sucks, but it does have thin cylinder walls and the crank is not really meant to rev very high stock

I'm well aware of what a B20 rotating assembly consists of, and everyone knows that despite having the same crank & rods as an LS it cannot handle the boost levels that an LS can in stock form.
"Tuning correctly" is a very generic statement which we all seem to toss around alot...to be specific in this case that will involve dialing back on potential power production to ensure safety of the sleeves, more so than you'd have to do with other blocks if boosting them stock.

danny_ha

i had a b20b w/ gsr tranny in my ek hatch and there wasn't a civic w/ a b16 that could hang with me at the track. but on the highway, they got me at top end. i've got another ek w/ a b18c in it and its got no torque compared to my b20.

b20b = more torque

b16 = more hp

The thickness of the sleeves have nothing to do with it. It the casting design. Also you can rev the hell out of the motor if you replace the rod bolts. The crank is fine.

It really can handle the same amount of boost and will probaly make more power with the same setup as the LS. When I said tuning correctly I am refering to fuel and ignition maps. The number one reason the B20 sleeves fail is because of detonation. So once again correctly tune the B20 and it will be a reliable and strong motor.

Funny I noticed in your sig "B20VTEC - R.I.P."

You're still just saying the same thing over again without any extra explanations. And listen to your own words..."it's not the sleeves it's the casting that is weak". So, the block that supports the sleeves is weaker, hence the sleeves aren't as well supported which means they can't handle as much. I'm not sure why this dissention is still going on.
