im looking at buying a b18b motor that had an automatic transmission. now the transmission is off and it looks like i can unbolt the automatics flywheel (or what looks like one) and put my b16 clutch and flywheel on. so my question is, is there a difference between an automatic motor compared to a manual? if i buy the motor that was previoulsy automatic will it for with my b16 manual tranny? thanks

i read somehwere that it wouldnt work. just like to clarify????

 

It is the same just take out the auto tranny parts and your set.

Good Luck!

 

where did the misconception come from that the auto integra engine was different from the manual??? I did an auto to manual swap...i can assure you there is no performance lack

 

I have an Auto LS and I kinda regret getting an auto now but since it is my first car and I want to learn how to drive rather than concentrating on shifiting I got the auto. I have a AEM SRI and building up my transmission and suspension for possibly a turbo later on.

I <3 my Integra!

 

save yourself the headache...swap to a manual or sell it...do not turbo an automatic integra...i personally think its gay

 

wow, wow wow, guys. i had a b16 turbo civic. it blew in the fall. took it all apart and planned to rebuild it. it is going to cost alot more than i thought so im looking at buying a b18b instead. i went to the junkyard today and found 2 b18b's. one was buried in mud so thats out the other was just the motor. i could tell it had an auto tranny before on it because it never had a clutch or flywheel. some other weird disc. anways i just wanted to make sure that i could use my old b16 tranny on this motor than had an auto tranny on it. so there are no extra sensors or anything? just making sure because i cant return the motor to the junkyard. thats all. no turbo automatic integra here.

 

I just pulled two LS motors today from the junkyard and both are OBD 0 automatics. Is the intake manifold any different from the manual tranny version? My one friend said it is but I really don't believe him. I know the cams are usually different between manual and auto engines, and I am fairly sure this is true for all LS motors.

 

Good lord people... read!

There shouldn't be any differences between a motor that had an Automatic Transmission and a Manual. I know on Neons the autos had a larger throttle body and 1st gen DSMs had a different cam grind for more low end torque and a smaller turbo so I can see where your concern is coming from, but the mounting points and everything for the transmission to the block should be the same, I wouldn't worry about it too much. Also, I personally havn't ever heard of any differences in cams, heads, intake manifold, throttle body between an auto and a manual. But like I said, the B16 transmission should mount up to my knowledge.

By the way, an automatics "Flywheel" is called a flex plate

good reason

don't turbo an auto integra unless you build up the transmission first..honda auto trannys can't handle high power. and it would only be fast in a straight line..autox and road racing with an auto is terrible because you cant keep it in the powerband.

 

well the reasons for not turboing an auto 4 banger should be obvious... ....itd be more effecient for him to sell and buy a manual car or swap to a manual tranny....

 

make sure to use the flywheel bolts for the manual flywheel and not for the automatic, they ARE different.

good point, thanks.

cliff notes...seems as though the auto and manual motors are the same. end of storey

I heard a rumor that I don't believe about auto cams on a LS. A friend of mine said they are slightly more aggressive than the manual ones. He actually bought a set of auto LS cams, and put them in. He said he felt a difference, and his powerband was more broad. I personally think he's lying out his *** on that one. He's been known to BS from time to time.

The manifold is very slightly different. The auto version has the EGR valve, and has one more vacuum port than the manual. Other than that, no visual difference, and I'm sure no difference in performance.

 

is that manifold difference going make the swap harder?

 

why would you believe a stupid rumor like that, does that even make sense? Car has an auto tranny probaly intended to be the grocery getter and get great gas mileage... yet they put a more agrresive cam in it. Its like making an AT LS/VTEC... rofl

 

are you joking...im lost. is there actually a different cam in the auto. i dont think the IM is different though.

 

the auto cams are NOT different in any way...the engines are identical...

 

haha, ok. i dont really care about the difference in cams anyways

 

Check for an IACV.

 

where is it located on the IM? by the TB?

if you are going to do an auto to manual and you need any help just ask. i did 2 auto to manuals in the last year. just like above you will need manual flywheel bolts, along with a manual starter and a few new bolts. starter bolts and i think 3 longer bolts to mount the tranny to the block. you will need new front and rear mount brackets and a new top motor mount. i have a list here somewhere if you need it

I told you I didn't believe it, but it was still a possibility. I brought it up to see if anyone else had heard it.

But dude's explanation was that Honda put a very slightly more aggressive cam in the autos to make up for the drivetrain loss, which is greater than a manual.

But I'm pretty sure he was bullshittin' everyone.
