AE92 engine swap, what should i use? AWD conversion? - Toyota Nation Forum : Toyota Car and Truck Forums

Apo11o · 02-08-2005, 11:16 PM

ok, i got an 88 AE92 sedan (DX) for free , it has 170,000 miles on a stock carburated 4AF, im planning on swapping in a manual trans and either a 20v AGE or a GZE, what would be better...

concidering the sedans curb weight is a hair over 2200 lbs (lighter than GTS) im hoping to have a fast, yet practical car that is very dependable. Is the 20v a dependable engine? And does it take as much fabrication and other voodoo to install as a GZE into a sedan?

Im looking to spend about $1000-$1500 overall on the actual materials.

Also with a 20v due to VVT it is possible (theoretically) to run low octane (engine just retards the timing to compensate), does this harm the engine at all?

OR... should i just get a 16v and say to hell with the crazy engnines...

thanks...

Also... i was wondering if it were possible to convert to AWD with the new engine, whatever it may be, how much would it cost and how hard of a conversion would it be?

i have heard of an 89-92 AWD sedan even not just wagon

Thanks...

The center tunnel isnt big enough for AWD stuff on a AE92 sedan, its different on the AE95

i was runnning 87 octane on my ST 20V 2 summers ago when i was broke. i runs fine, but you'll feel a bit torque when you run high octane. just do the usual maintenance. goodluck!

thanks for the 20v info, i think im going to go with that instead of the GZE

Is there a way to make the tunnel bigger, i.e: fabrication a bigger one and welding it in, or even welding the AE95 part on?

Thanks

You'll need to cut the stock oem channel out and firewall. Open it up for the tranny. You'll need enough space for trann, shaft and exhaust. Don't know if engine mount same as FWD. You'll need good shop to do it right so body not gonna twist or get weaken.
BTW don't know if 20V is good with AWD, its low in torque.

Apo11o · 02-09-2005, 12:42 PM

Yeah, i know that tourque is low, that was if i was going to use the GZE, im just curious, it would be pretty cool to do, kinda like a WRX or EVO, i would like to rally race, ive done some (light) off roading in my car, kinda funny when you have to get your friends to push your car out.

Does the 20v have a good reputation as far as reliablility? Because it would be a daily driver...

20V parts are hard to get and pricy since its a Japan engine. North America never got it so most dealer will have no clue what it is.

Actually he could use the AE95 stuff, the transmission is almost the same as the AE92, but it just has a shaft going to the rear, no need to cut up the firewall, only the tunnel has to be swapped from the AE92.

that cant be that hard, i have access to a welder, and there are many junkyards near by, so all i would really need is the tunnel and all-trac transmission? i imagine it would be funny to ask a junkyard if i can have just part of the body but its worth a shot.

also, i understand that the 20v is a JDM only engine, im not asking if dealers would know anything about it, especially since i use a performance/tuning shop for all of my maintinance, is it *dependable* i need to know if its suitable for a daily driver.

otherwise i would go with an early 4AGZE so i could burn low octane gas, though cheap gas isnt imperitive, its nice to not have the driving costs of a big V6

Apo11o · 02-09-2005, 06:18 PM

By the way, how much do you think parts alone for the AWD conversion would cost me?

***REN69*** · 02-09-2005, 10:40 PM

Where are you gonna find an AWD transmission to fit on a 20V or a 4AGZE????

No AWD car ever came with either motor.. just the 4AFE, and I doubt that transmission would take the punishment a 20V or GZE would give it (remember the 4AFE only has about 100hp-100ft/lb of torque). You should really read that one thread in the Celica forum about how useless it is to try and duplicate a Celica ALL-TRAC/GT4 from a GTS.. You're looking at suspension, chassis strengthening, transmission (if you can find one), driveshafts, fuel lines, fuel system in general, etc... you'd be better off just staying FWD since either 20V or GZE conversion would mean you'd need to re-wire and re-everything just to replace the 4AF motor. If you got the money, time, and parts sources.. sure why not! go for it. I'd rather stay FWD... I'd actually rather do a FWD 3SGTE conversion myself rather than converting a car to AWD without having the right resources.

Apo11o · 02-10-2005, 12:51 AM

i was more or less curious as to if it could be done, but it think you can interchange thransmissions or am i wrong, on the AE92gts website they used a 5sp from a 4AF (i think) on a 4AGZE, they just reinforced the clutch.

i am probly going to stay FWD though i dont have the money to do it anyway, just engough for engine stuff and new suspension.

***REN69*** · 02-10-2005, 09:33 PM

Hey.. whatever you wanna do.. you'll always need lots of money.

there were ae92 all-tracs.... i think the ae95 only came out in 92 over here..... the only difference is in the wagon, and the hood/headlights/grill look different..... the ae92 sedan alltracs look identical... i've never been under one to compare, however
