ok first off yes i have searched but i seem to not be able to find any specific information. So yea doing the beloved Auto/manual Swap and have most of the parts to do this but still confused about the transmission i need to get. First off i have a 1995 240 SX auto non abs and no Vlsd :-( with the KA24DE. With that being said first thing that comes to mind is yea ODB1 no bid deal got it means i dont have to worry about the sensor on top of the trans the Speed sensor or whatever it is. So considering finding a trans is being difficult what year is a good donor car. I know your gonna say same year as car and all that but what i am wandering is that if the 91 - 95 trans (odb1) and the 96 - 98 (odb2) are they generally the same? With that being said thanks all who take the time to look. Oh and detailed info is a plus thanks all.

you need the one with the sensor on top. its an s14 deal. you can use the s13 trans but you will get a check light from not having the sensor. a long time ago i made a template to drill the hole for the sensor in an s13 bell housing, but the dude never returned it to me. so ya use the s14 bell housing. its still obdII even though its 95. look under your hood on the catalyst and it will say OBDII certified.

the thing is, is that the as far as smog is concerned OBDII didnt come out till 96 when it was mandatory to have it on all gasoline engines. nissan had it in 95, but it wasnt quite the same as the 96+ but none the less you still have an OBDII port on your 95 and also under the hood is proof that its OBDII. also you have two oxygen sensors, and a lot of other things that are all on OBDII vehicles. i understand its not "technically" OBDII but it is also lol. doesnt really make sense i know, but regardless you need an OBDII trans with the crank sensor in it.

i have done the manual swap myself on my 98 240 and i used a 95 transmission and all other parts from a 95. also i have owned 3 s14's all with KA's and all OBDII lol 2 95's (one early model and one late model) and one 98. so for your original question "do you need the one with the sensor" answer is YES.. hope i cleared it up for you.

ok good cuz I have an S13 trans for my S14. So I can swap the auto S14 bellhousing to the S13 5speed??

Yeah I think only a very few 95 240's were OBDII but most are OBDI

Motoman already said it but to put it into simple terms... Most usdm s14's are OBDII but america did not require OBDII until 96, meaning that the 95 cars are still emission tested using the good old sniffer test or whatever your state uses.

see thing is i dont really care about emissions im in the states that done require it Illinois and Kentucky i just want to know if it will run properly i am doing an EGR delete as well so do i need the extra sensor? and as far as bellhousing it would have to be the Manual s14 bellhouseing as the auto wont work right? what sensor is it exactly and can i get away with not using it and not have a damn CEL i hate those

the sensor that goes on top of the bellhousing is the crankshaft position sensor. s14s came out with that sensor as the s13 didnt. i have a s14 wit a s13 transmission in it and it gives off a couple codes that arent letting me passs smog. like a code for the torque convert n somthing else...i actually have questions how to get rid of the codes myself.

well the parts i have are as follows

s14 Clutch Pedal (just gonna trim the brake pedal)
auto to manual Line to replace hard line
the shorty Hose between old hardline to slave cylinder
oem Clutch master cylinder
11lb Flywheel
Clutch Kit (pressure plate, clutch disk,throw out bearing)
manual trans crossmember
Manual ECU for a 95 S14

guess i will just get the newer Trans like i had intended lol

hmm also read that the rear section of the DS is the same should i just find the front part or go with a solid DS?

and as far as using the auto trans bellhousing i dont think that will work

you will need the manual trans bellhousing bolts, and manual trans flywheel bolts also. you might as well get the manual trans brake pedal.. since there is one next to the car you got the clutch pedal from..

Actually Motoman OP was right on this one. http://lmgtfy.com/?q=OBD1+Nissan+S14 95=OBD1 96-98=OBD2
US Production #'s
1995 - 25114
1996 - 7334
1997 - 3655
1998 - 2178

Slightly less than twice as many OBD1 14's are around compared to OBD2

Sorry I love using that Google link, don't mean to be rude haha

how many s14's have you owned or actually worked on. i have owned 3 and have worked on a few others.

riddle me this.. if the are OBDI, then why do they have an OBDII access port that works with ALL OBDII code readers? huh bub? why do they have two oxygen sensors, one before the cat and one after the cat? why do they say OBDII certified under the hood?

you googled info that is commonly wrong. it looks like you put wikipedia info, which is info that is made up from people, not always factual.

here click this link and read the first thing http://lmgtfy.com/?q=wikipedia

Hey motoman, i've had my OBDI (9/94 build date) S14 since 2002. It has 2, one wire, o2 sensors that it uses for reference. They are not heated, they are simple one wire o2s. OBDII access ports were not mandated until 1996 model year vehicles, but many manufacturers started earlier since they were switching over to their new computer equipment and readers they wanted reverse compatibility. Hate to burst your bubble, but even though they have more emissions control than older cars, it's still not the same as the OBDII mandated-compliant vehicles.

how about where it says OBDII certified under the hood. i know that "technically" its not OBDII because its not 96+ but the car was built as OBDII. it is a more simple version than the 96+ though. but look under your hood and it will say "OBDII CERTIFIED" i promise. also, make sure that your s14 has 2 single wire O2's cause my 4/94 build date s14 had one single (upstream) wire and one 3 wire (downstream). check that out and get back to me. thanks..
