4A-FET Build - Toyota Nation Forum : Toyota Car and Truck Forums

AE92_BOY · 09-29-2005, 04:10 AM

hey ,

I'm doing a little home work for this build . And so far I found some stuff.

I know that the 4afe will take mild boost without hardened bottom end. how can I get a hold of hardened parts for the 4afe?

- Is there a doner car?
- will I have to make my own parts?
-how much boost will this engine take.

forgive the noobness My playground is the SR20DET Nissan Camp. so boost is ramped.

thx

i think the pistons off a 4AGZE will fit.

just get a gze block/motor.... you'll be better off. The factory pistons are forged, the crank is forged, and from factory the pistons/crank/rods are almost perfectly balanced. On top of that, they have oil squirters

yeh, get a 4A-gze swap, the 4a-fe isnt worth messin w.

AE92_BOY · 09-30-2005, 08:36 PM

hey thanks for the input. I do know that thay did offer it in this car for IIRC 2 yrs. now the GZE is the supercharged GE right. offered in the Jspec corollas?

how much am I looking to gain from this swap compaired to the just turboing the FE . I'm not looking for a HP monster, just a sleeper for daliy driven affairs.

thx

if ur looking for daily driven affairs, i suggest u just turbo the 4afe

if ur looking for real power, then an engine swap would be nice, i'm kinda stuck on this situation also

"f ur looking for daily driven affairs, i suggest u just turbo the 4afe"

Why do you say that?
The GZE makes a perfectly docile daily driver.

this might be something you'd want to look for...

TOMs turbo kit for the 4AFE (bolt-on)

comes complete with an ECU already

AE92_BOY · 10-01-2005, 12:28 PM

is that a t-20 turbo on that kit? I found on in NJ. with turbo-kits.com I just wanted more info
and for go the blind boosting drama.

Actually an aftermarket turboed car would be worse than a stock force inducted engine. Theres ALWAYS gonna be reliability issues.

SpeedballTrix · 10-01-2005, 01:47 PM

Which is why he should drop a GZE in it

Cavi Mike · 10-01-2005, 01:49 PM

Any engine can handle a small amount of boost, like 5psi. With a lowered compression ratio you can get more but, lowering compression ratio just to get more boost only creates a ton of lag and less drivablilty and not much more power except for in the higher rpm ranges.

Typically the pistons are the problem in any situation because they aren't designed to take the extra heat, they just melt. The 4AGZE pistons are a good idea, but if you're going to dissasemble the engine to put pistons in, you might as well change everything.

It all comes down to what want from this car, if 5 psi and 35-40 hp is plenty for you, then have at it. Make sure your coolant is fresh and if you live in a warmer climate keep your water ratio higher. Use good synthetic oil like Mobil 1 and take care of your car like the manual says and you won't have any problems.

AE92_BOY · 10-01-2005, 11:47 PM

hey,

thanks for the on going help. for sure..... the kit I saw was 5-7lbs of boost with a 56% HP gain. So that should give my little FE a 150ish HP right.

And now if I go to swap a GZE what will something like that cost? if I had to guess I would say

2500-3000 bones..... if I did all the work.

You can boost the 4AFE with good success for around $2000 if you do all the work yourself. The beauty of it is, if you blow it up, it's no big deal since 4AFEs can be had at most junkyards for less than $300.

The best option for reliablity, however, is an engine swap, because in that case you are running a stock engine (just a stock engine from a different car). Putting on an aftermarket turbo system will decrease reliability.

AE92_boy, those numbers sound familiar. If you're looking at the turbo-kits.com "Superior" or "Extreme" kits, stay far away. Those kits do not bolt up as advertised. Custom is the best way to go. There is an abundance of info on turboing the 4AFE on here, celicatech.net, 6gc.net (they of course have the 7AFE which is the 1.8 version), and some other places. Search around and you will find all you need.

Also, the 4AGZE pistons will fit into the 4AFE, but because of the smaller combustion chamber in the 4AFE, the compression ratio ends up being around 11:1, which of course is very bad for turbo. The best option for a low compression rebuild on a 4afe is here: http://www.importperformanceparts.net/
