gze/20v half cut - what to look for

[Shifty]

Hey guys

I'm looking at getting a half cut shortly, just wondering if there's anything in particular I should be looking for problem-wise on either a 4AGZE or a 20v.

Also, any guide you can give me as to what does/doest'n come with (or how to identify) what has an LSD, what is a 6sp or 5sp, and what has the superstrut suspension (for the brakes, of course).... also anything else desirable I should be aware of in choosing which half cut I buy.

I'm aware that the AE101 4AGZE has the highest factory output, and the AE111 is the more powerful of the 20vs... anything else I should bear in mind?

Cheers

Leigh

the black top 20v has lighter but weaker rods than the silvertop (ST has same rods as GZE) also lighter pistons,
higher compression for the BT as well.
ST is AFM, BT is MAP, so is the 101 GZE (MAP that is).
101 GZE has individual coils IIRC.
BT has 48mm throttles as opposed to 45mm on the ST

.... thats about all i can think off the top of my head.

while the 20v's are great engines if it you are going for a dailydriver that you want alot of punch from low-mid range then go GZE as you can add a T later

half cuts unless specified come with everything (usually without wheels) from the front footwell forward and typically have some form of damage.

edit; pretty sure all 101s came with the super strut, but check with one of the FWD experts, but dont get too close they all are ghey with teh aids

Having looked at the dyno thread, the AE101 GZEs seem to make good power and the 20v dyno sheets mostly seem to suck ass!

I love the tidy appearance & simplicity of a 20v but ~75-85kw at the wheels isn't a lot better than I'd expect from my fresh bigport.

If anyone has a 20v in Brisbane and can take me for a burn, that would be great.

Would definitely prefer a MAP version so it's down to the AE111 blacktop and the AE101 GZE. Decisions, decsions...

depends what ya like but there is no way a big port will be making 85kw at the wheels, when i get my 20v in the 22 dyno'd im expecting 90ish rwkw which is a realistic figure IMO

when i finish my drop tank installation and get everything running you are more than welcome to come for a ride

as for map v afm. get an st and run after market ecu that way ya get the benefits of the stonger internals and better combustion chamber design

Definitely not, but I said 75-85kw at the wheels is "not a lot more" than I'd expect a good bigport to make. At a random guess I'd say a bigport should make 65kw at the wheels, so if I spent $4k putting in a blacktop 20v and got 75kW at the wheels I'd be very unhappy with the result!!

I know of a silvertop half cut for $1750 so if I was lucky and the clutch was good I could probably get away with $2500 for the swap and it would be a nice result for that money.

I know of a GZE half cut for a shade under $2k but that's an older one and I'd prefer an AE101 cut which seem to be a bit dearer... by the time you plumb it all up with a cooler and stuff it's a $5k job done properly so it's double the money.

I'm not interested in that kinda stuff for this car, I'm really just interested in dropping in a stock motor for a good powerup and keeping it as close to stock as is reasonable... I'll see what's available when I'm ready to buy.

SO......................

......what has a 6sp and what doesnt?
......what has the superstrut brakes?
......how do I identify the lsd gearbox (build plate?)

Superstrut was an option (might have been standard on higher spec models though)

[X kyle X]

Go the ae101 GZE you will be happy with the power they put out standard..

But do some research as they have the "power drop" which is a retardation of timing that the factory ae101 ECU does, it is heaps touchy!!

Superstrut was an option can't remember the model but it may be the BZ-R as I owned a GT apex and it wasn't superstrut...

The 6 speed box was never optioned in the GZE models...the GZE from a ae101 was factory LSD E 58 but the ae92 and aw11 was an option..

You need to look at the Trans/Axle code on that little silver plate on the firewall on the halfcut. I think Witzl has posted the different codes, maybe JP as well.
Superstrut is easy to spot as it has the twin piston callipers.
What is your recipient car? If you're putting it in an AE92 then choosing a MAP AE92 4agze is the easiest option.

My silvertop got 85 fwkw after an emanage tune. They go nice with a TD04L on them and about 6psi

Open up the oil filler cap and check for gunge. It should be nice and clean in there. In Japan a car will get a sticker on the cambelt cover when the belt is changed. But the dates are in Japanese format (the year of the emperor, of something.)

C52 is the older 5 speed box on the 4ages
C56 is better. - 04C I think is the factory LSD. - 15C is Open Centre.
Is it C150 that is the 6 speed that came as an option with the Black Top?


Also 85kW is a TRUCKLOAD more than 65kW in a light car like an AW11.

C160 is the axle code for the 6-speed in the blacktop. Silvertops had C52 and C56, blacktop had C56 and C160, and the GZEs (no AE111 GZE) had E-series boxes (don't know as much about them, but they're all 5-speeds and significantly heavier/stronger than C-series boxes)

I want my powahs! If I installed them, I want them!

Factory LSD on all AE101s? Check.

It will be going into an AE82 Twin Cam.

Just keep this picture in mind if you're thinking about turbocharging down the line...



If you intend on turbocharging then i'd say go for the GZE straght away. I had a smallport at first in my sx.. swapped for a silvertop, saw less than 10fwkw more than the smallport. Admittedly I did prefer the silvertop as it felt much smoother through the revs but now that i've got the turbo motor in mine I'm wishing i'd just gone straight for boost from the start.

p.s. if you end up getting a silvertop then throw in a lightweight flywheel straight away, I put a 4.4kg Toda one in mine and it was by far the best bang for buck modification.

[damo101]

when i went in to order my halfcut the guys there said all ae101 GZE had superstrut suspension and were all LSD..optioned on 20V versions. im going to say go for the GZE. so much fun in an ae82. i finished my ae101 GZE conversion about 2 months ago. very happy!

FWIW, ae101 4agze has an e58, i think series 2 ae92 GTZ have e58 and series 1 ae92 GTZ has e51 or e52 cant remember.. someone correct me though if im wrong.

[Shifty]

AE92 rods look pretty serious! Interesting that AE101 GZE seems to have smaller rods... either way I'm planning to keep it stockish (perhaps an SC14 and a little more boost?).

I'm onto:

a silvertop 20v for $1750
blacktop 20v for $2200
AE92 GZE for $2200 (I know of one that just went for a shade under $2k)
AE101 GZE for $3k

GZE prices seem a bit ridiculous for a little toy motor, shit I can buy a 2J half cut for $3k!?

Given those prices the silvertop seems like the best choice, although the likely lack of LSD and superstrut brakes does take away from the 'value' perspective.
