Has anyone atempted a 4e-fte swap?

Afro · Post by **Afro** » Sun Nov 25, 2007 6:14 pm

I was thinking of doing a 4e-fte swap. My main concern is space. Does the turbo manifold and exhaust junk fit with the brake booster and stuff? I know I'll run into some minor problems, like fuel delivery, ecu etc but I already have solutions to that.

Just a side note, the tercel 4wd has a 4e engine right?

I searched the forums for 4e-fte info and found none. I hope I'm not asking something that's already been answered

The Tercel wagon, both 2 and 4WD, has the 4A engine. The transmission is seriously weak for anything putting out significantly more horsepower and torque than the stock 4A, which was rated at 62HP.

Actually that is the 3A engine 1453 cc and yes only 62 hp. A swap to a carb 4A engine is easy should not overload the drive train, and you gain about 10-12 hp I think. The 4afe or age will gain you 40 to 70 more hp but will be a more involved conversion with custom exhaust, converting to EFI, etc. The 4- series of engines are 1.6 liters.

I would not put a turbo in this car only because the cost and trouble would not gain you anything that the NA 4 series engines can get you for a lot less trouble. You lose reliablity and long life (of both engine and drive train) by over powering it with a turbo.

I see, I see. Well I'm not too worried about engine problems or working in the efi. I used to work as the tech at a performance shop and have done enough to be confident at least. Although the drive train does worry me, I don't plan on bagging it or even racing it at all, I just wanted a good deal of power for highway and good fuel econ. (which turbos or slightly more powerful engines with comparable displacement can provide as long as you don't ham them of course.) But inevitably I will want to stomp it now and then and I really don't want to blow anything.

I have been doing some research and although a 20V 4A-GE would be real neat it would be overkill and problems like 'body molding' for the distributor would arise and I hate 'molding' the body. I think I'll swap in the 4A-GE 16 valve Blue Top from a AE92 with the AE86 4A-GE intake manifold. Anyone attempted this?

Just as a side note question... did the newer model tercel come with the E engine?

One of the problems you will run into doing the 4AGE will be the flywheels, the stock 3ac is 6 bolt and 4age is 8 bolt, in order to get the flywheel to fit inside the tranny you will need to use the 3ac flywheel. Your best bet would be to do a 4AC swap with a 32/36 and exhaust.

4efte will NOT bolt to the tranny space is not an issue if you still use the tmic, im turbocharging my 3ac so ill do a writeup soon

i just compleated the 4afe swap and all i say is wow!!
i also have a 4ac with a weber 32/36, both have exhaust and whatnot.

there is no comparison the 4afe has so much more smoother allaround power. and its not even broke in yet. plus i live at 7000 feet

4age would be ideal but the price is up there, the motors out of a ae86 are 1k+ as far as the flywheel you can use a bottom end out of 4ac or 4afe and no problems with flywheels. although the 4afe has a better tq curve than the 4age.

Absolutely correct, it was late and I had the 4A engine on my brain.

The 4AFE crank will bolt up to the 3A flywheel. Both use the six bolt flywheel. The 4AFE are more common and much less expensive than the 4AGE. There is someone on the list that has done this, but required the firewall mods for the distributor clearance.

An "easy" conversion for the distributor that would not require cutting the firewall is to get one of the distributorless set-ups out of the newer Tercels (do not know what year they eliminated the dist. but I saw one at pull-a-part). You might have to switch to the newer ECU with the distributorless ignition system, but I do not suspect that will be problem if you get all the correct sensors in the right places.

I think the EFI is the way to go, especially with the 16-valve head. If someone attempts the distributorless conversion on the 4afe and shares what they learn here, I might consider doing it myself.

I wouldn't want to swap a crank into the 4A-GE because that would somewhat defeat the purpose of using the one out of a AE92 (strengthened). I like complicated projects that don't involve body work haha so that's why I think I'll be leaning to the 4A-GE 16V.

I got a good diameter pic of the 8 bolt pattern at

I may just get the 3A flywheel machined, although I have two ideas for a possible solution to the 8 bolt issue that doesn't include welding or swapping cranks (as soon as I get my answer I'll let you all know if it works).

I'm selling my 4runner so I'll probably sink that money into this project. That's why I don't mind the ~pricey engine... aaaand I can get stuff cheap haha.

if you know someone at a part store you probly could look threw there flyweel book and find one with the correct diam and bolt patern and tooth count. there books are amazign for finding non stock parts

If you are machining the flywheel anyway, then take as much weight off of it as you can. It is way too heavy. Then have it rebalanced.

Yeah, the carbureted 3E was used on the '87-'90 Tercels (excluding the Wagons, which all had 3A engines). And in '91, the EFI 3E-E replaced the 3E in the Tercel. I'm not sure of the exact year, but the last of the Tercels got the Paseo's DOHC engine. 5E-FE, I think?
