Default Ls tranny into b16a motor, would it fit properly? If so, would it be efficient? Good or bad combinat

I have a rebuilt ls tran w/ new clutch and I see a b16a motor only for sale I was wondering if the ls tran would fit into the b16a, would a rebuilt tranny w/stage 1 gripforce racing clutch perform ok on the b16a? I don't wanna pay more than a grand for the b16a tranny if my b18b tranny is in good condition. Any help would be appreciated.

it will fit but its not a good combo the LS tranny isnt meant to be revved into the 8500-10000 ranges

It's not so much that it's not meant to rev that high, it's about the gearing. The LS tranny will make a B16 seem pretty sluggish and you most likely fall out of the vtec range in every shift. You will get better gas mileage but that's about it. It will make your car slower that's all. It fits like oem.

I see, thanks. You see I blew up the head, was thinking about ls-vtec but when I did research found out that it's not reliable.

They want $1,000 for a b16a motor only and one wants $100 for a b18b complete head and $400 for a complete b18b. I have to think about the ecu and $400 labor aswell.

The LS trans will work on the b16. What hurts the LS trans, is the 4.2 final drive and milder 3-4-5 gears.

For the disparity in price, I would go with a B20 or B18 engine. Put a 4.4 final drive or better in it. If you want to be more aggressive, than get a VTEC 3rd and 4th gearsets. Leave the LS 5th in for cruising.

i don't know who told you the ls vtec is unreliable but they don't know what they are talking about. i have friends that have ben running them in there cars for more then 5 years no problems. if you build them right they are a good motor. when they first did them back in the day there were problems but now its all figured out no more problems at all

a stock ls tranny is not a good match for the stock or mild modded b16. i wouldnt recommend it unless you are making a decent chunk over 300 hp...

hi guys. i have a quick question...
What would the outcome be if we were to use the 1st, 2nd and 3rd gear of 2 B16a transmission and the 4th & 5th of a B18b? Given that you have a B16a motor doing 113kw on the wheels.

Thanks

The gearing in ls tranny sucks and the torque from the b16a sucks, most likely the engine is a automatic engine making even less hp (smaller cams). Put this all together in a integra (if that's what you have)=bad combo - I would sell your tranny, buy a b16a tranny and do a ls/vtec

where are you getting your info from??? the ls transmission does not suck, its just not made for the b16a motor... its made for the ls motor

what does an engines transmission have to do with how much hp it has? the problem with automatics is most (depending on cars setup and what the car was made for) have shift points set for economy and gas mileage

i'm in the middle of doing exactly this right now.
i have a JDM S1 and a USDM S1 (cable), and am replacing the LS 3rd and 4th with the b16a gears (main and counter).
i've been searching like a bastard, made threads looking for opinions, and there doesn't seem to be much info around on this.
i'll let you know how it all went after the weekend.

interestingly enough, the ls tranny is still a closer geared trans than many many other cars (vr6, k24 nissan.....)

but you are talking about a 6 cylinder engine and a large displacement 4 cylinder engine that both make more torque than a b16 does. Of course the LS is closer geared than a tranny attatched to a vr6 or ka24de because the 1.8Ls b18's smaller displacement makes for lower torque requiring closer gears

Slow down and read for a second, I said the gearing in the ls tranny sucks - 1st gear is the same gear ratio but 2nd-5th are longer gears and it has a 4.26 final compared to the 4.4 final in the b16a - nobody here was talking about building a b18a to shift at stock redline and thats the only thing a ls tranny is good for unless you are running 135mph in the quarter or want good gas mileage. I also was simply saying a b16a engine being sold without a tranny is most likely a auto engine with 10hp less than normal - not a big deal

It's not the most ideal then either....149mph and b16 ratios here.

hha yeah but my 93 toyota tercel had a very long tranny too and that pice of crap 1.5L didnt make more than 70whp lol.

im still a big fan of the ls trans if you are making like 300 or more hp in a street car
