4agze ae101 turbo

[quadthrottle]

I've looked through the forums but can't find all the info I'm looking for

I want to do it as cheap as possible.
This is what I'm gonna do, do I need anything more?

Exhaust manifold
Turbo back exhaust
Turbo
Intercooler and piping
BOV

My dad can do all the piping and exhaust and stuff as he's a real good fabricator plus I already got a exhaust manifold for a T25 that I'll modify. So all I need to buy is a Turbo, 4AGE Inlet manifold and throttle body, Intercooler and BOV?

A VF10 should be all good turbo?

Any good pics of this conversion done in AE101? Pics of the piping and exhaust mani and stuff

Also is a Apexi SAFC going to work? Any one got it going? I've read mixed results. But can get one for $100NZD and I wont be able to afford aftermarket ECU

Cheers guys

Do you have an AE101 GTZ Levin? If so, Those things are rare (so you should keep it supercharged... SC14 all the way ), there's only two I know of in Australia.... I got one of them. The other is in Perth.

You're list is pretty much correct. You'll have to fabricate an oil pickup and return for the turbo, and the intercooler piping could be a bit tricky, especially if you have ABS (common on the GTZ Levins) as there is almost no room on the drivers side for the pipework.
Use a gen 2 3SGTE throttle body as well, not a 4AGE one. The 3SGTE TB will allow you to keep the ECU controlled idle speed control instead of the wax pellet in the 4AGE one. I ran both on my 4AGZE, and the 3SGTE throttle body has the benefit of not allowing the engine to stall all the time...... Both the 4AGE and 3SGTE are bigger than the 4AGZE TB, 55mm in diameter rather than 50mm of the 4AGZE.

Cheers mate, Im in NZ and here they're dime a dozen lol. So where is the best place to put the oil pick up and return? Thanks I'll keep that in mind, I can already see a possible hole to put it. Will the 3SGTE bolt straight on to the 4AGE intake manifold? I already have one (I got the turbo manifold and intake manifold for $150NZ and the turbo for $80) And will the 3SGTE throttle make it any eaiser or harder to tune? Now to try find one cheap as this is a budget build

What years are the gen2 3SGTE? I got a TB but it has a wierd linkage setup for the throttle so gen3 maybe?? Could you post a picture on your website please? Also is it only the 3SGTE TB or is 3SGE similar?

[TERRA Operative]

The 3SGTE TB will bolt straight up, the J-pipe on the 4AGZE, it will just need a bit of enlargement though. A Dremel or flap sanding wheel makes short work of it.
It will bolt straight to the 4AGE manifold with no modification to the manifold at all, as the TB's are the same size and bolt spacing.

I used a Gen2 TB on my GZE, The Gen3 is 60mm and has a different bolt pattern, so won't fit at all. I don't know the years for these engines but Google or Wiki will help.
If you look under '3SGTE Throttle Body Install' on my website (in my sig) you'll see how I did the swap.

I believe the 3SGTE TB is the same as the 3SGTE, but I cant confirm that for sure.

Anyone no where to have the turbo oil return? Do I need to drill a hole in my sump? And can anyone estimate my power output after? I was thinking of running 12psi on 98 octane will this be too much? Will I be looking at around 200hp? Also I was thinking of getting rising rate fuel pressure regulator and Supra injectors, will this make much more power if I do that?

[Casey-G]

Sump return would be the best bet, i think if you get a 4age sump pan they already have a fitting in there for a oem oil cooler and since the GZE didn't have one you can just use that... or just weld a socket in the sump instead of looking for a 4age one.


I also highly recommend the 3SGTE throttle body upgrade terra is suggesting he has had very good results playing with his Levin and believe he knows best.

Looking forward to pictures matey, keep us updated on the conversion! i have a GZE converted to turbo going into my AE92 Hatch, so im always interested to see other peoples work on these motors!


Also on the fuel bit:

I believe the OEM fuel pressure regulator is a rising rate, the standard GZE injectors should be up to the task of 14psi, and it will be easier to source evo injectors as they come in sets of 4 not 6 like the 7m supra injectors.


12psi is a pretty safe figure as many have run 20psi on a stock bottom end and had very little problems. (thanks to the great over engineering of toyota)


you will push the 200 hp mark but around and beyond that you should probably look into a fully programmable computer to be on the safe side

Cheers mate. Will any 4age sump do the trick or only certain ones? I always thought it seemed a bit wierd the most powerfull engine didn't get a oil cooler aye. Cool, I've sourced a 50mm 3SGTE will this still be effective?

On the ECU side, what's the cheapest one around? I've been scared of them because of the +$700ND price,which is more than I'm getting all the parts for to turbo it! The SAFC was dear enough at 250. Will running bigger injectors give me more power or will I need to increase boost and change timing too?

Also will the bluetop cams make much difference? And will I need to get an adjustable cam gear for the exhaust to retard it or can I do it another way?

Thanks for all the help, pics are def gonna be coming on here :]

[Casey-G]

To make the most of the cams, extra boost, and the 3S throttle yes a adjustable cam gear set will make the most of them all. But you can run the cams without the need of adjustable gears.

Bigger injectors wont do anything until you need them hence why most use the stock injectors till they start pushing the bigger numbers.

ECU's well a lot of blokes are having a lot of success with adaptronic they are a newer unit with a ever growing fan base, still on the cheaper side of the market as they are new but have all if not all the features of higher end makes, so maybe have a look into them.

to start with though i see no problem with the 4agze unit till you run for bigger numbers.

with the sump i'd say stick with a 16 valve engine as i think there is a slight difference in the oil pump pickup on the 20 valve engines, i'd be looking for a smallport or bigport sump as i believe they both came with oem oil coolers.

Would just an exhaust adjustable cam be fine? Intake won't make much difference for the cost?

A bluetop sump will be fine?

[jono]

my JDM smallport didn't have any oil cooler or at least there was nothing on the sump to indicate a factory return, we had to braze a fitting in there.

[quadthrottle]

So it might be easy enough to drill a hole and braze a fitting on there? That won't be too bad as I can braze pretty well haha

My AE92 sx seca made in 89 has a oem oil cooler, you will find any aus delivered sx corolla will have one.


You will have to pull the sump off either way so you mas as well weld a 3/4 socket on there. (or in your case braze)


you can run just 1 adjustable cam gear on the exhaust side to close up the valve overlap a bit. I think terra did this in a similar way, and was able to squeeze about 13psi out of the SC12 (oem set at about 7-9psi) with stock pulleys with use of the 3sgte throttle body and a plated of ABV valve.


What inlet manifold are you running?

[TERRA Operative]

The 50mm 3SGTE tb will be no upgrade from the 4AGZE one. You want the 55mm one (I got mine from a gen 2).

You don't need the adjustable cam gears for the bigport cams, but they do help.

What Casey-g said above is true. Re. the boost in my Levin. I use HKS cam gears on intake and exhaust, I just gotta get on a dyno to tune them properly.
Just be sure to reset your ignition timing whenever you adjust your exhaust cam. The distributor is driven from the exhaust cam, so any adjustment will throw the iming out.

[quadthrottle]

What inlet manifold are you running?

A 4AGE one. I got it and the exhaust mani from a guy for 150

Sweet as. Are there any other hidden problems I'll come across?

Will put photos up as soon as the car arrives and then of the repair and build up, as no one seems to do this often. Still haven't found any phoitos of intercooler pipes and stuff but I'll just wing it
