Hey guys,

I'm new here and wanted to get something straight. Are the 7A-FE motors from 90's Corolla the same as the 7A-FE in the Celica's? I have a 97' ST Celica that threw a rod bearing and I'm looking for a replacement engine. Would it be safer to buy a OBDII 7A-FE from another Celica or would a 94-95 Corolla motor do?

If a Corolla motor will do, what are some of the things I would need to use from the Celica 7A-FE to work with the 7A-FE in the Corolla motor?

Any info would be appreciate. Thanks!

a 94/95 Corolla motor would be too much trouble since it's OBDI

>

Okay, when did the Corolla's go to OBDII? 97? And would a 7A-FE out of that year be easier to swap into the Celica?

On another note, I can't seem to find any 7A-FE motors from 97's, I've only found a few out of 96's, are they the same as 97's 7A-FE's aka OBDII?

Yeah, anything '96 and after is OBDII. That's when the change was made. and the Corolla with the 7A in America was the AE102, from 93-97

>

So a 96' 7A-FE out of a Corolla or a Celica would simply drop right back into my 97' Celica?

Anyone with any suggestions?

The OBD1 would also work with minor mods basically you will swap the Intake manifold from yours to the new engine

check out my thread, its in the exterior styling portion of the site, i went through the same thing basically
i am putting in a 94 celica st engine into a 97 shell.. its almost done, and i put up all the problems and changes i had to go through... good luck either way!

there is bad info here, sure the year went to ODBII but that doesnt matter. the OP threw a rod, thats the bottem end! any and i mean ANY 7A bottom end will work just fine for you. all you ahve to do is put your head, manifolds, and accessories on it. sometimes you might get away with long block swapping just using your electronics.

Get out of the box, there is always an option

I have no knowledge of putting a motor together so that's why I choose to just buy another 7A-FE motor and drop it back in.

Question here is which motor would be easiest to drop in? I can't seem to find any 97' 7A-FE, is a 96' the same?

And 96st, what other minor mods would I need to make a older OBDI motor work?

wow. lots of misinformation here.

you can use just about any 7afe you want, keeping these things in mind.

if your car is 96+, like yours is, and you use a replacement out of an earlier year, you will have to use the following parts off your current motor.

intake (with throttle body) and exhuast manifolds
coolant waterneck
crank position sensor, oil pump housing, and crank pully with intergrated trigger wheel for the crank position sensor
possibly fuel rail and injectors (but thats more a 5sfe thing)
harness and ecu
thats the short list.
basicly anything on the motor that has a sensor, your gonna wanna check against what you have, and make sure they are the same. if not, use the part off the old motor.

^^^ exactly, usually when you buy a used engine, you only get the longblock, no manifolds. so you will have to just transfer your stuff over. its not assembling the engine, just the sensors and manifolds.

That sounds like a lot to swap over. I'm a Nissan guy and when I dropped a earlier motor year 93' into my 97' chassis, I swapped distributor and intake manifold and ta da that was it. Is all that stuff listed above just SOME of the items I have to swap over? That sounds like a lot of stuff. =\

not sure how you got away with that since you put an ODBI engine in an ODBII car

>

Does anyone have a list of what is all needed from an OBDII engine to make a OBDI engine work in a OBDII chassis?

Someone said I should search and trust me, I searched before I joined the forums but I had no luck.

Pretty much, you just have to take everything off your '97 block, then put it all on the new block you get.

I'm looking to do a swap. The donor car being a 1996 Corolla 7afe. The car it will be going into is a 1996 Celica that already has the same 7afe. I haven't looked too much at the coroll but i did notice the map sensor is a bit smaller and different, other than that things look the same. I get work release from jail everyday so i'm lookin to get this all done in 1-2 days. I've done a few engine swaps and builds so i'm wondering what problems i'm going to have that anyone knows of before i start at it? I know i could play around and take my time and read an fsm on both but kinda short on time. Thanks

Did they teach you to read as well?

Cause...yea..scroll up.

>
Aww don't be so harsh

I laughed, though

>

Lol, i'm usally not. Tend to be quite peaceful.

Dudes name is "Vagina" though, then asked the same damn question as the original post. Hard to respond serious to that =P

Read? What's that? And where in the earlier posts does is state the complications, if any, of doing an obd II 7afe into another obd II 7afe? Please enlighten me And going from the same chassis is an obvious given that everything should work (depending on year), But i'm looking at an engine coming out of a corolla and going into a celica. Just in case some of you forgot or can't read earlier posts

Edit. So to ask question into simple terms... What differences are there between the obd II 7afe in a 1996 toyota corolla vs. an obd II 7afe in a 1996 toyota celica? I noticed the map sensor is different. What problems would I have with that? Can i just use my map sensor? I think I can but I know there someone on here that's done this a time or two that has some pretty useful info that'll help alot. Thanks.

you will use YOUR MAP sensor, your sensors, your manifolds.

Really?? Who would of thought of using the sensor's that go with the ecu? Especially the one's that don't match? ....People are getting smart :0 Haha anyways.... Who know's if I can pull the ecu from the corolla and use it as a back up? Or what the difference is between the map sensors? And what else is different between the 2 cars? Am I going to have to eliminate any sensors that may be on the corolla? Do I need to wire in any sensors that didn't come on the celica? And please, if you have no useful information, don't post. I'd rather not read a bunch of ****. Isn't this a tech forum? And yeah I know i could go through an fsm and figure this out all on my own....not hard. But then what would be the point in this site? :-) -thanks

The problem is, the answer is right in front of you. On this thread.

But instead, you choose to thread jack, and then proceed to come back with a **** attitude.

Figure it out

Edit:

For the sake of being a "tech forum" which I don't believe this sites main and only purpose is to help ignorant people.

Switch your block, keep everything else as it has been stated before. Obviouslly keeping anything that is identical.

Sorry, i didn't mean to thread jack. But i'm sure this topic could use more information than what's here. Why would i waste money on gaskets to swap things that don't need to be swapped? i.e. throttle body, intake manifold, egr, injectors, fuel pressure regulaor, valve cover etc... Does that make sense? Can anyone post the differences between the 2 cars/engine's? Any useful information before this thread get clustered with arguments?

Edit- And i'm going to try using the block, and head, so basically complete engine minus sensor's and vacuum lines and other small things. This way i don't have to do new head gasket and make this alot more complicated swap.

Also the current engine is blowing out alot of oil. Going through about 1 qt every 500 miles. I don't know if it's the piston rings that are going bad or the valves. In either case I'd much rather do a quick swap instead of spending weeks or months building the current engine and finding oversized bearings and boring and honing and all that fun stuff.

>
My 7A used to do the same exact thing. Then one day, it just kind of... stopped. I still can't explain it, but my oil level stays where it should and doesn't drastically go down extremely fast anymore. I don't know whether it's a good thing or a bad thing, but she runs just fine.

So you don't have problems found in this thread.

http://www.6gc.net/forums/index.php?showtopic=78796

My 7a also eats oil like its candy, but is also leaking so I can't really determine which is eatting it faster. Meh runs great, just bleeds like a stuff pig....but this is also why i have a 3s otw =p

GL, but no one is going to have a comprehensive list of each engines diffrences. You are going to have to swap'em out, and compare them side by side, or switch just the block as said.

I think the OP wanted to know what pieces would have to be transferred from block or head to another block or head. Being from obd I to obd II or vise versa. Well having information of differences between obd I and obd II as well as differences between 2 obd II 7afe's sounds good to add into this thread to ME. Thank you for the good input, and when I do this swap I will try to add some more information that I find. As for the oil leak it's coming through the engine, it's done it for a while and progressively getting worse, so I don't think it's going to just go away and even if it does i'd much rather have an engine that doesn't do that and hasn't done that. My head was gone through about 120k miles ago and the bottom end has 273k miles on it. I think it is time for another one. Eventually i'll be getting rid of everything and turning this into an "all-trac" celica with a suby ej25 (?) platform. I know it'll be alot of work and alot of torching, welding, drilling, wiring, etc. So knowing as much about this car as i can is kinda useful. But back on topic i'll see if i can find the differences and get pictures and post them. Thanks again.

Sounds good, thanks for working with me. I apologize if i was a bit harsh before.

Seeing a list would be quite helpful to some. Most likely the reason we do not have a list of that sort, is there are so many changes between years, and majority of 7a don't die early enough to put another 7a in, most just drop a 3s in there, or another 7a from a celica.

It's all good. I see where you were coming from. And the more information, the better. So i'll get up what i can with the 7a swap.
