I'm not sure if you guys have seen this site:
http://www.turbocorolla.com/cars/larsc.htm
but it got me thinking about what needs to be done for a 20v or 4agze swap. It seems like it may be fairly straightforward.

Perhaps nobody on here has done it themselves, but I was curious if anyone has any information about it (maybe a link?).

So far all I've managed to dig up is something about bolt pattern on the flywheel between the 4af and the 4ag and some kind of ribbing on the block.

Funny, we both posted the same link at the same time.  I came across Lar's page several years ago, and just dug up the link from my bookmarks.  Notice that he has a strut bar.  If he can do it, so can we . . .

Hello all,

I've got a 90 all trac wagon in the ever popular red/maroon color. I just picked up a 20v engine the other day and am planning the swap for this coming march/april. I'll keep y'all updated on how it goes.

Anyone know hoe much power the stock clutch and tranny can take? If it is similar to the celica all trac than I'm all set...otherwise time to start looking

From actual users' experiences (as on TurboCorolla site and ToyotaCorollaModifications.com site), it appears that the drivetrain can handle the extra power,
but probably or most definitely not to the extent of a Celica All-Trac.  Cuzman (the guy at http://www.turbocorolla.com) explains this on his postings of this mods.
I'm sure if you look there are others who have done the same.

adammtb, definitely interested in your project! Let me know what kind of things you encounter!

My 4afe is still very healthy, but we'll see how it handles a summer of autocross.. I just want an excuse for a 20v lol

Here is another example of a 20v engine swap from Australia.  http://forums.club4ag.com/zerothread?id=24643.  I don't like the wheels; they look plastic to me.

Good luck with the 20v, plenty of people have done it, not so many in a 4-track... There's a few different types of 20v's as well & from what I've read on other sites, they're not all created equal.

The common consensus from a few aussie guys I've contacted who've done alltrac conversions is to go the 4agze route.

The 20v is said lack power/torque down low but all good in the higher gears.

None the less I'm sure you'll enjoy more grunt than the 4afe especially if you upgrade the exhaust when you're doing the conversion.

I just came across this thread on rollaclub.com as well:
http://www.rollaclub.com/board/index.php?showtopic=18903

This caught my eye:

If you wanted to drop in a replacement engine, you should chat to Tim (zmit) as he's got an AE92 Corolla Seca for sale with a reconditioned 4A-F. Other engine swaps are possible (and easy to do), like a 4A-GE, either sixteen valve or twenty valve, or a 4A-GZE, which is a supercharged version of the sixteen valve engine. The 7A-FE would also go straight in to give you a 1.8L engine instead of a 1.6L.

I think my wagon, in a year or two, may be in line for a 4A-GZE. haha =)

sorry to bring up an older thread (not too old i guess since it was the 5 1 down from the top) but in swapping the motor, i know you need to do the ecu as well.  i am planning to purchase an all-trac sedan from a local fellow and do a 4agze swap when i have the chance to.  the problem is that the sedan now is an auto trans, and like 98% of the 4agze engine and ecu combos are for manual trans.  so my question is, with the ecu and the push button awd on an auto trans, will there be a problem with using the ecu from the manual donor car?  thanks for the insight guys!

I think I would be also worried about the drivetrain handling the power from the engine...

yes upon further research, ive seen and decided that a gze engine will not work.  many people have posted that the drivetrain is flimsy for that much power.  they recommend going turbo instead.  either 4afte or gze to gte.  gze to gte takes some modding, but a** i understand it, it is less than doing fte, and you can get bigger gains out of it.  just boost below 8psi.  still out on the ecu dillema though.  i know it could be solved by getting a manual trans, but im sure its going to be near impossible to find.

20cents worth..

I've read exactly the opposite in other corolla forums. The AE95 standard drive drain is unusually strong for a car of it's size & engine capacity.
It's true, the supercharger on a 4agze gives you a good start at low rev ranges & this does mean extra pressure on the drivetrain but keep in mind the power going to your front wheels really spreads the load, so the added load you're talking about is within normal parameters. Plenty of manufacturers have upgraded new models with small roots type superchargers like the sc12 without changing the existing drive train.

I am guessing...  but from all I've read it's unlikely to do any serious damage to the drive train, unless you're repeatedly redlining & then dumping the clutch!

The one person I know who's put the 4agze into an AE95 is Lars who's responsible for the australian green machine seen web-linked in a few other alltrac threads. He also built a naturally aspirated one with either a silver or blacktop 4age a few years back... (can't remember off the top of my head)

But he wanted even more power, so he removed the super charger from a 4agze & turbo'd it because the 4agze has the strongest internals of all the 4a engines
(not sure what size turbo)

So that's another thing... "what size turbo are you planning to fit?"
Maybe you could upgrade the clutch plate if you really wanted to but from the research I've done, the drive train's pretty solid. Keep in mind the comparatively low factory 1st gear ratio that the alltrac comes with tends to protect the drive train too.

You're right not to bother trying to make a 4afte. The engine's built for economy, is lighter than the others & not even a true double overhead cam, it's actually a slave cam on one side, doesen't have the extra re-inforced ribbing on the engine block that the others do, there's a good chance it'd blow.

Re: ECU, your best bet is to buy a complete front cut of a car that has the engine you want, that way you get all the extra bits you need. OR you can keep an eye out online, sometimes people sell engine, ECU & fuel pump set ups

Cheers!

Good Luck!

I've just emailed a wreckers yard to see what they want for this old MR2 hopefully it's still got the 4agze & all the components I'll need with it.

It's been online for 5 months & had about 156 views

I've been considering an engine swap someday... I think the key will be to take it easy on the drivetrain.  Just because you can punch it like no other, does not mean you should.  At least not all the time.

I agree, there's not point reving it above 6k & then dumping the clutch but as I said before, the load does go to all 4 wheels, not just the rear, so you're already safer than most 2wd rev-heads anyway...

If you click on Lars's link again

http://www.turbocorolla.com/cars/larsc.htm

you'll see on the drive train he says:

Driveline:       Standard 4wd gearbox, CV's and driveline, heavy duty clutch

Next time you're driving down the road take a look at the size of some rear axles then pop your head round the back of your car, or underneath if you prefer to look at the drive line as well...
You'll notice the AE95's axle ( & driveline's ) very solid for the vehicle's size & horse power of the engine.

A heavy duty clutch plate's all you need to take the extra load of more kilowatts / horsepower ..& you'll see, that's the one item he mentions...
