running 4agze NA

[evil86]

hey guys, im doing the 4agze supercharger conversion because my 4ac died out on me and i didnt want to go 4age because im look for more power later on. so what i was thinking was getting a 4agze and running it NA.

Situation: i wanna get a a 4agze take of the sc12 and bolt on a big port manifold.

Question: has anyone done it before? what would i need? can someone help me!!


thanks for reading

[egg_83]

are you on your p's? Why not just leave the sc on there?

[evil86]

yes im on my p's. it sucks to be me

It will if you're driving an NA 4agze...because of the lowered compression, it will drive like a dog, which isnt necessarily that bad a thing as long as you know there is a reason...in your case, having to do it to advance your power later on..when you go for the extra power later on, should just put a turbo on, you will have your inlet all sorted, as most people run JDM Bigport inlets with turbo setups as it flows air a lot better...

[evil86]

yeah, thats what i was thinking. it will run like a dog but i dont mind. im fine it that.

[Vance]

it will run as good as a 4ac

[AE86R]

yeah my mate done it, will run better then the 4ac but no where as good as the gze or 16v na

[70XIN]

my intercooler piping used to pop off completely all the time

even driving it "NA" for those small periods wasn't too bad, i wouldn't say it'll be all that fail

[Gilly]

yeah its not that big a deal. if you use AE101 GZE the comp ratio is higher than earlier ZE's so it wouldn't be too bad

definately still better than a 4ac

if anyhting it would drive like a tired GE

[evil86]

would anyone know what i need to run the gze NA. part wise and a how to...

[Nikkojoe]

As said, a late smallport gze has a compression ratio of 8.9:1 which puts it close to a bigport 4age. They aren't that bad really, even my 8.0:1 early gze in NA was still much better than a 4ac.

Just leave all the gear attached, can just unplug the supercharger or remove the charger relay (and remove the drive belt if wanted). Run a J pipe from the charger outlet to the inlet manifold on the head since its opperating as NA. Most of the usual 4agze to rwd conversion stuff will still apply (like cooling system, clutch/flywheel, etc).

Good luck :)

I went in fronozby's AE82 hatch after he took the supercharger off to do a turbo conversion, It went good still.

As everyone says, yes it'll work, but wont be exciting.

To do it you really need a full 4AGZE and then drop the SC bits. I think 4AGE gear is just different enough to make it too much hassle to try and run a ZE with it. Coils, dizzy etc.

Another option is to fit a 4AGE now and just crack it open and drop ZE pistons in if you go to turbo/SC later.

interesting ... ive got a 4agze now with a turbo. its been tuned for 150rwkw on a mircotech ...

will i have to get it re-tuned so it can run properly if i was going down the same path as the topic starter ?

i also have access to a jdm loom and comp .. if i bolt that striaght up will it run ? and more importantly damge any components in the process ? ( recently been re-built for a turbo application ... soon to get my licence back so i wont be able to drive a turbo vechile)

[hugh]

If your computer has been tuned to run boost and then you take it away, it will be confused, kind of the same as running boost on an NA computer..can be done but not very well at all...
rather than getting microtech retuned for NA, i would just put the JDM loom and computer in and disable the supercharger as Nikkojoe said earlier...

[Konakid]

Buy a bigport now, when you get off your P's, turbo it.

[dustyae86]

at the moment my car is sitting in the garage with a nevo on it and I haven't got it tuned so I have driven it with the SC unplugged and let me tell you it is gay as gay can be

[reecegze]

a bigport 4agze in NA is a good platform to work from phouc and there is little left to do when turboing it .. Get your parts whilst yo can still drive it, is the smartest option. Once you get all the parts its a days job to turbo the bludger.. Run Max 10 psi on the motor and it will push 140kw on 10psi pretty easy and would be good for a mid 13sec pass

[evil86]

cheers reece will speak to u soon

No. A well tuned turbo car should also run well with the turbo removed. The "tune" for the car will cover both manifold vacuum and boost. Remove the boost and it still is mapped for manifold vacuum. The reverse is not true of NA cars.

Having said that, there are other disadvantages of a de-turboed motor, like low CR and so on, but the tune isn't necessarily one of them.

Just my 2 cents,

but why don't you replace the 4ac with a working one. Most people give their 4ac away so that should be a reasonably cheap fix for the short term.

As for getting a Gze, your talking about taking a front wheel drive motor and converting it to rear wheel drive, then removing the charger and running it as N/A.

What i would do is just get the car running as cheaply as possible (4AC) and practice your driving with a motor that works as it was intented too.

Then i would buy a block or whole motor and build something from the ground up, and do so outside of the engine bay which is much easier. this will give you time to prepare parts and save cash for the conversion.

and you can do all that whilst your still driving aroung thrashing the kunt outta that 4ac and learning how to drive a car. that is why you are on your PROVISIONAL's. so you can learn.

[evil86]

first. i had a 4ac till it broke down... and i wish to build up my 86. i have a secondary/daily car already. i dont intend to drive my 86 much on the road. the gze motor that im getting is already off a 86 so most of the work is done for me.

[slideways]

well in that case just chuck the gze in and drive.

running it N/A will be an effort, but its up too you.

or if you only drive it occasionaly, register it in someone's name that has a full lisence. and then just tell the nice police man your the designated driver and that your really sorry for "bending the rules" :DD

[evil86]

reason why im running it na is because i can drive turbo/sc. and also i need IC and Ic piping

[slideways]

If your running a GZE, higway patrol will see the supercharger and be like, this mofo only on his P's motherfucker, we gonna take you down biatch.
and then you'll be like but its not hooked up, so it's still N/A.
And he'll be like, spread em' punk!

capiche?

[sundee]

dont run a GZE NA! ive got a mates ae92 with a GZE in it and the sucker aint boosting. it goes half as good as my 16V NA!!!

[Trev084]

The intake system would be letting it down as it is getting restricted, If it was breathing better it would go better.

[redsprinter]

umm . i dont know how relevent this is but when i was at oran park my intercooler pipe on the inlet manifold pop off and it was n/a for 1/2 a lap and wasnt to bad ...

[evil86]

i not worried about the power output of a NA gze, atleast it runs:)

[reecegze]

Effort why is that ?? .. all hes gotta do is remove shitty sc12 gear throw it in the bin and slap a smallport manifold on, run the pod from the intake.. Eezzi. A smallport 4agze will go alright still phouc.. In the end your goals are to turbo it later.. Thats the easy part..So get the motor in as NA and then slap the turbo gear on later Walla no need for all this other crap

[Mickey H]

I'm in the same boat as you man, I have a gze but I'm on my P's for another 13 months. I just bought a 4ac for 100$ and I'm putting that in, while I'm doing a complete rebuild on the gze. by the time I'm on my opens, ill have it fully rebuilt, and ready to go in. I think that's the best way to go. N/A or not, a gze is still and engine swap and can you can still get fined for it.

[evil86]

im planning to shave the rocket cover. let see how it goes, my 4ac is coming out on sunday

[HACHI - 6X]

+1 to reece !!

LOL fuck your 2cents !! he wants info ... not people telling him to go put this and that!! who gives a fcuk if hes on provisional or not if he gets pumped then what can he do, your not the one that is gonna get raped! all he was asking is if anyone has done it and wats the go? the 4ac has had it times, so its time for something new. we have been discussing about this issue ever since and its come to the point that the GZE will go in whether its stays charged or not. wat he wants to know is what needs to be done to get it running NA.

[redsprinter]

phouc . its pretty striaght forward dude..

check out your bro's ae86 and copy it .. try and keep it the install as jdm as possible.. try and soruce a jdm loom with all the sensors and plugs + matching ecu .. i think i saw one on ebay the other day ... you can either cut and shut a fwd manifold or find a jdm rwd one ...oh and the water system if you can get the jdm one thats a bonus. nice and easy cause its already rwd format .. if not call me and ill try and help you our with it ...

and the most important part for a street driven car i reckon is try and find a jdm fuel tank. save you from surge tanks and what not ... do it once do it right ... no defect too ...

phouc if you havent already bpught your gze motor and have plans on turboing it later on i reccomend .. and i only just learnt the other night that the late smallport share the same block and crank as the gze..only difference is the piston and rod ...some one correct me if im wrong ... so when it come time for a turbo ... go the re-build on a small port and get some gze pistons lower your comp.. and your sweet. food for thought ...

[evil86]

thanks john man, i've deposited for the motor already, its from bretts n2 car

Thats the whole fuckin point, does he do that everytime he wants to change it back and forth? and as for a turbo conversion thats way easier to do with the engine out, plus you don't have too take the car of the road.
So slap a 4ac in, and walla no need for all this other crap!

And as for HACHI -6X, your a dumb KuNt, i'm just tryin to answer the question this guy is asking, and i'm talking from first hand experience not what i herd from my mate down in the shire.
