4agze's...

[l1ttle_d3vil]

http://www.geocities.com/MotorCity/Garage/8422/4age.htm

on the 4age table down near the bottom of that page; which of those 4ages are the gze models, if any...?

just trying to work out which 4agze would be easiest for me to pick up and put in my car using parts i currently have / am currently familiar with.

otherwise does anyone have a website which has all the specs of the different gze's like that website?

cheers.

None of them. its a 4age only table.

club4ag has a good list of info but im not finding it for you

Any 4agze is simple as to put in to you car, do you want to turbo it or keep the sc12?

either way the blocks are pretty much identical, with a few exceptions like

aw11 has dizzy, rest has cas.
Only late ae92 and ae101 ar map, rest are afm
As above, map ones are high comp, and perhaps weaker as rods are smaller and pistons are not of same forging
alternator mounts different it aw11 i think.....

other than that theyre basically bluetops with a sc12, no external differences really.

Best block is ae92afm with turbo, as are strongest, or ae101 for stock sc12, as have better compression with drivability.

yeah i wondered if it was just n/a 4ages. i've found the list on club4ag but it doesn't have all the information im after.
* which of those gze's are bigports? i'm hoping to use my ae86 manifold, so will obviously need a bigport gze as opposed to a smallport.
* is there any difference in turboing a dizzy gze as opposed to CAS gze?
* is there a simple way to get around the power loss the map sensored gze's get at 5500rpm, without going with an aftermarket computer? will the one way valve the club4ag guys mentioned fix this?

1: Bigports are all the 8.0:1 blocks, mr2 and early ae92.
2: Nah not really
3: Who farken cares dont worry about it, youll be buying an afm anyways, and if you get map, theyre better anyway

[Adamal]

I was under the impression that all 4AGZE's were smallport. Have I been misinformed?

[no_8wire]

yeap...aw11 bigport all the way!!!

probly not, probly just havent listened to everyone

sweet, that narrows down my options quite a bit.
how are maps better? i wouldn't be able to convert a bigport gze to map anyway as there are no dizzy + map sensored gze's to swap the ecu's from are there?

are there many bigport gze's around or are they stupidly hard to find?

[matt dunn]

AW11 are all Big port GZE.

AE92 GZE. Non facelift pre mid 89? are big port aswell. They run an airflow meter.

AE92 GZE Facelift from mid 89 on? are smallport and have a Map sensor instead of AFM.

AE101 are all smallport and map sensed also.

[Mr Revhead]

small port face lift is about 5th month of 89.

[l1ttle_d3vil]

is there any way of telling if an engine is bigport or smallport from just looking at it? or do you have to pull the manifolds off to make sure?

[Mr Revhead]

look for a AFM if it has one its smallport

[Caveman]

Id get a map sensor small port, they are easier to plumb (no afm), have the better smallport head, higher compression, oil squirters and knock sensor.

From what i have heard afm ones lean after about 10psi on a turbo. ih8tec blew his up, dont know how much boost he was running but he said it was lean and detonated to death.

[matt dunn]

Ah, not quite, but I think you know that.

If it has AFM it's bigport.

The Easiest way to tell is quite simple.

Look for the external oil drain from the head to the block.
It comes out of the Right Rear corner of the head,
(right side being intake side)

ae92 gze are bigport, but have AFM too. if it has a dizzy then its a bigport obviously (unless its been converted from CAS) as it must be from the aw11.

i would prefer to go with the map sensor, but I need a bigport to make the conversion easier. I need to be able to swap as many parts as possible over off my current bluetop setup.

crankn said earlier not to worry about about the power loss map sensored gze's get at 5500rpm; why is this? is it hardly noticable or what?? would a link ecu fix this?

[Mr Revhead]

haha yeah, i had typed MAP but then decied to put AFM as they are easier to see! forgot to change the rest!

and yes the oil drain, thats the bets way, forgot about that
a ECU etc could be changed, that oil drain is harder to change

Just listen to me, and what matt said, he just wrote mine with years. The others are not telling you correct info, and never do.

Just buy what you can, you will not notice any difference at all, other than the afm is a little different to install.

You will have no problems, as you seem to research everything well before doing it.

Just buy what you can find, with the lowest possible km's, and youll be fine.

sweet!

hey hey, without the extra injector i could do 12psi with turbo, when i melted i was running lots more boost, lol, about 18psi with the extra injector. not really sure what went on there, we have suspicions.

[Crucible]

From what i have heard afm ones lean after about 10psi on a turbo.

So do map gzes from as low as 11 psi on stock ecu turboed, They also have boost cut at 15psi as you know, I had no fuel up to 8psi with mine and have fuel charts to prove it aswell, I dont have powerloss at 5500rpm after i converted to turbo, it pulls to redline.

If your going with a hi comp map gze and turbo go with aftermarket computer, theres really no other option if you want the best out of your set up.

just my opinion

Dude, Nothing against you or anything man, but you need to stop talking down to others aye, Ive noticed on quite a few occasions you doing this.

No worries or anything but is it really nessesary??, maybe this is why people keep having a go at you?. You seem to know what your talking about but others have opinions too and this is a forum.
