emanage or aem what is working better

[tech]

i currently have a 91 na and i am going to buy a 3sgte or a 3sge (not sure yet) swap this winter and was looking into engine management. I was thinking the aem ems or emanage ultimate for sure the only thing is i know ive seen cars with emanage before and they wouldnt start in the cold very well but i could rewire it for different engines unlike the aem and the aem is $2000 but the emanage is only like $600 price isnt a big deal but is the aem really necesary? i was thinkin of trying a couple different engines but dont want to have to buy a new aem every time i change an engine harness. will the emanage work well? what about nemisis it seems pricy to with everything said and done. and does it only work with the 3sgte? andis that usb compatible or not? is anyone using emanage ultimate? any information you guys have would be great.

oh and does anyone know why the greddy website says emanage works on most japanese cars but the emanage ultimate says it only works on cars supported by software? what does that mean? it will work for mr2s right? and emanage is usb cable right?

Personally I'd go with the Hydra Nemesis instead of either of those

if price isn't an object why not get what's better? it's safer to overbuild when it comes to cars that are driven hard!

this is my first mr2 owned alot of hondas in te past so ive used the aem and emanage before but never on a toyota not sure how theyll react but this nemisis sounds like a good bet. is it usb compatible or do i have to have a computer with a different port on it, what is the software like is it like the aem or hondata. and how can i order it? and is it actually completely plug and play or some wiring needed like the emanage if someone uses nemisis curently it would be great to talk if they are up to it hanx again guys

What are you mods to constitute an EMS right now? The point of an EMS is when you start modifying past the scope of the stock ECU.

AEM > E-manage btw.

thats the thing is that i have a 91 na right now and i havnt een able to decide what swap im doing yet. i was thinking the 3sgte or mabey the 3sge but then havnt decided if itll be my daily driver or not if not then i might go ahead and do my first plan of using my 5sfe block and crank that are in my car with the 3sgte head and rods but not sure on the reliability of thatbuild so might stick with the 3sgte build looking for right around 280 to 300 at the wheels if i get my other car running soon enough if not then the 3sge swap for now cant stand the 5sfe oh and im not sure what tranny to run yet either everyone keeps telling me to run the turbo tranny but i was thinkin about putting aftermarket lsd in the non turbo tranny which would you guys do?

If you are gonna turbo it get a turbo tranny; iirc the turbo tranny has longer gears which is more beneficial for a turbocharged car, if not just keep the na tranny!

If you do decide to do the 5s block with the 3s head lmk because I am building a new engine and will have a full 3sgte spare that you could use for parts that I will be selling for fairly cheap! I bought a jdm 3sgte that I am using for my build so I have the jdm pistons/rods/cams that could be used if they are better than usdm, I'm not sure!

[tech]

yea the longer gears would be nice for holding boost how strong are the differentials in those trannys though ive had many stock lsd honda trannys where the spider gears just snap on the diffs on me. how much power do they hold reliably? where can i get an lsd tranny cheap? and then dont i need the axles and then the hubs as well. how much would you want for the engine i could probably pick it up depending on where you are. is it still a good engine or is there something wrong with it.

canthe nemisis be used on musltiple harnesses like if i were to go withthe
3sge then use it when i build a 3sgte?

[tech]

any tranny bolts to any motor right eg. (turbo tranny bolts to 5sfe or non turbo tranny bolts to 3sgte) is that right

You need to decide what you want to build. You are looking at harnesses that have completely different ECU connectors.

[tech]

yeah i know that seems to be the problem i think im gonna stick with the 5s until i build the 3sgte i plan on just getting a whole rear clip now i think it seems cheaper and easier than peicing it all together is that chico race works a reliable source has anyone used them or where did everyone else get their swaps from?

well a few different things here, the trannies are good themselves; most people use stock and rebuilds are commonly seen but these cars are 12-16 years old!

and the 93+ were the only ones available from the factory with lsd, but not all were lsd equipped, it was an option; and the 93+ have double syncros which generally hold more power and are less likely to need a rebuild, and if they do it costs quite a bit more than 91-92; and to run 93+ lsd the do use different axles; I believe the driver side is different but passenger is the same(not 100% on this)

about the engine it is still in the car and runs but the hg has a crack between one of the cyls and a coolant port! Runs great but need a hg which I could include a brand new factory toyota, it leaks a little oil so it would be beneficial to replace gaskets! I could include the whole long block with intake mani but no ex mani, I will need the engine harness but that's it! I live about 30 min from milwaukee, not sure where you live; Price depends on what you all want, I have like I said 2 engines and I will be rebuilding the jdm so I have the pistons and cams from that one which could be used woth you swap, but if I wouldn't want much more than a couple hundred!

Only the 3rd gear got a dual cone synchro. 2nd got a triple, and 1,4, and 5 were kept the same between 91/92 and 93+.

am I correct here?

do i need the interior harness for the 3sgte swap or no?

Yes you do. Don't buy or accept delivery on a clip without a full, intact body harness. I suggest you do your homework on a 3s swap before you end up doing a lot of extra work or spending extra money buying parts that should come with a clip.
