4agze questiosn

[Dirtbag]

righteo, looking to buy a new car, most probably aw11/ae92 with a 4agze, so it will come with the either first or second "gen" 4agze, after looking at the specs http://www.club4ag.com/faq%20and%20tech_pages/4A-GZE_specs.htm its obvious that factory, the older it is the "slower" it is, but in reality how big is the difference? I would be looking to tickle it slightly with couple things I have seen around eg pulley to up the boost a little, make sure exhaust is unrestrictive etc. Would I expect to see the samish gains regardless of 1st or 2nd gen 4agze? Is it very hard to swap the ecus and sensors to create a MAP gze out of an AFM gze?

I ask this because most cars that I have seen have been early model ae92 with the 1st gen 4agze, and keen to buy, but if the difference is quite large between the 1st and 2nd gen and worth the looking around for longer, I probably will.

the dyno on that page with 120kw... would pulley kit and unrestrictive exhaust come anywhere near that? Or would I be looking at more work to get numbers like that.

And lastly, whats the exageration factor that toyota plonked on 4agze factory power outputs? What would a stock 4agze pull?

AW11 motors are 140hp according to factory. There was a post up not long ago that mentioned toyotas power figures are based on an the engine with like nil load. So fairly unreliable. I've got 1st gen with 12psi pulley. It goes quite well alot quicker than a standard 4age. Wanna buy my car?

[Dirtbag]

haha, perhaps, where abouts in the country are you? What kind of price you looking for? Can ya post up some pictures and stuff of it? Of email me at p (dot) mcgirr (at) orcon.net.nz

Have to say ive owned a NA 4age before, bigport 4agze goes real hard in comparison. My gf has a 20v which i drive sometimes too, and the 4agze really puts it to shame. Even my mate who has a cossy was quite impressed due to the instant power, though you cant really compare the 2 since the cossy would leave a 4agze in the dusty once it actually got traction

You wouldnt want to turn the AFM gze into a map version, thats not where the power comes from, the newer gze has smaller intake ports and higher compression pistons and a smaller SC pulley. If you want those things youd be better buying a newer gze in the first place.

[Dirtbag]

Yea, when I was looking at ae92/ae101s I had a ride in a gtz and by god did it pull, compared to the 20v there was a whole lot more push right from the word go, but then it's kinda understandable.

So by "newer" gze you mean the ones in the late ae92s, or in the ae101s? I really ain't keen to get an ae101 as it will come with superstrut again and I have already faced the horrors of that. AND cos I am only looking at spending 2500 max, which judging by the contents of the buy-sell recently should net me an ae92 gtz.

What kind of boost do they run stock? And what kind of boost does it run with the smaller sc pulley?

[cr1mnl]

not all ae101s are superslut but yeah trying to find one for 2.5k is another story. some people say the ae101 runs a smaller pulley on the s/c but i havent compared the two myself. most standard ze's seem to run around 7psi however changing the crank pulley to a 175mm dia should see you get 12-14psi depending on s/c condition. One other thing all the map sensor verions I've driven all seem to have a dip in power at 5500rpm. Not sure if its the same with afm. Other people have noticed this too and theres varying opinions on what causes it, some say ecu, some say supercharger efficency.

The 5500rpm thing is due to operating temperature. I had problems with a rwd converted MAP 4agze because of the position on the thermostat, it always ran a bit cold and would ALWAYS hit a wall at 5500.

After I'd sorted the thermostat setup and engine is up to temperature it fly's passed 5500 easy.

So FYI, it is nothing to do with the s/c. But in saying that, the s/c's are pretty inefficient anyway

Also had an AFM early 4agze for a while and that had no problems with hitting rpm walls

on my car, ae92 with afm, i had 14psi pulley (but ran 12 and 13.5on cold night) also had pod and exhaust, thats all and i had 101.4kw atw on the dyno. and also ran consistant 14.7's. and that used to beat ae101 gtz's with those mods plus some.

so maybe that will answer your question

ae101's are heavier too from what I understand.

[Dirtbag]

Just out of interest, why would it run less on a cold night? Wouldnt the fact it was cold be packing more air in? Was that with the stock top mount etc?
And yea, cheers for that info IH8TEC, pretty much answered a whole lot of my queries.

The gt-apexs are heavier, so it woulld be expected that the gtzs are heavier aswell.

[Lith]

Probably if it does, it will be because of denser air - it'd imply the supercharger is getting inefficient normally and the boost level is coming from the sheer heat levels.

[bluemaumau]

if i was chosing a 4agze powered car itd be a facelift ae92.

better primer apparently, lighter, map sensored.

[Dirtbag]

Yea, thats I would want to do, but I cannot seem to find any facelift gtzs around that are also within my price range. How much lighter are they?

[escortman]

he doesnt say it runs less boost he says more 12 and 13.5 on cold nite, ull find that with any forced induction car

[rallyrulz]

AE101 4AGZE 1180kg, 4AGE 1120 Kg. Extra weight is mainly gearbox I believe, its a stronger LSD box. Infact most things on the GZE are stronger.

Car runs much better in cold temps (night), probably because of the small and crappy intercooler. Has anyone put a larger inter cooler onto a stock engine? 92kw at wheels for an avg stock gtz 101. Weight seems to make a huge diff on how much these cars can pull, 2 ppl in the car slows them down dramatically, well thats my feeling anyway, would be even worse with a 20v.

AE101 atleast has the SC12 which means max 12psi, pully kit makes 14psi, cant do more than 14.7 on SC12 else they melt or something and thats ECU limit.

[Dirtbag]

2 people in a 20v is noticable, 4 people it nearly feels like your driving a tractor, especially up hills the weight it super noticable.

So with the afm 4agze ae92 gtz, whats the chance of getting an lsd box?

[bluemaumau]

yea i can feel a massiv diffence in weight between 2 and 3 ppl also.

afm gze with lsd box, dont think it was factory, so unless someones replaced it.

[Dirtbag]

Did they come standard in the facelift gtzs?

[themaleman]

keep looking bro, i got a map ae92 for under $2500!! and shit yea u notice the diff with 2 people in the car. im pretty sure none of the ae92's came with lsd boxes. but shoudnt b a problem fitting 1 from an ae101. and i have 3 4agzes with 3 difference pully sizes, 1 14psi mother and a standard ae92 pully and a standard ae101, 1 of the 2 is noticably smaller, so must b the ae101. good luck with the buy

[Dirtbag]

Yea, I have a afm ae92 in my sights at the moment for 2500 ono... im wondering how low I could push it.
