Hi Guys
Its time for me to get serious about finishing the truck and gettign it back on the road. I really need to have a look at a couple of other trucks to see what has to be done with wiring and plumbing and stuff.

Long story short

Who in Brisbane or the Gold Coast has a workign ZE in a serria and would not mind me taking a million pictures and askign a thousand questions. I will bring Beer

PM Drew on here.

Brissie area

his was working and in a sierra but not std thou

but a wealth of infomation he has.

Ok i have PM Drew but no reply yet.

Does anybody else have a GE or ZE i can check out?

Posted: **Mon Dec 15, 2008 12:24 pm**

What exactly do you need to know?

Dank is doing a GE conversion and has a great write up in members.

Posted: **Mon Dec 15, 2008 1:32 pm**

Yeah been a bit slow on that lately but this weekend should hopefully see me getting the gearbox mount done and the engine mounted tacked enough to get the body on and check clearances with firewall.

I'm getting my wiring done by a pro because I can't be bothered trying to graft both my wiring looms together!

I might aim for end of january to be back on the road.

what radiator workes best In my GE powered zook I had a vit rad IIRC. Worked fine.
fuel pump VL turbo pumps are popular and fairly cheap.
exaust size and location No experience here but I would look at 2 1/4 inch for a GZE maybe bigger, exhaust shop will know better. Location is high and generally down the opposite chassis rail to your fuel lines.
break booster I'm planning on running a 2 bolt GQ master cylinder and booster. Search for CHOPZUKI's build in members for more details.
and stuff Asking for a rusty trombone on the first date DOES NOT always work. Don't feel that you have to stop asking though. Hope this helps :redflipoff:

If you want to fill up the back or underneath with excessive hose and surge tanks and external fuel pumps go the VL pump. If you want neat and practical and more than enough to do the job drop a swb EFI vitara tank with intank EFI pump. A bolt in option is a coily sierra tank with a vit intank pump. It already has the mount for it.

You could probably find a bigger capacity pump to fit into the cradle if you feel you needed to have more balls. Maybe run a rising rate fuel reg as well to feed the SC properly.

The vit tank will fit with just enough room to run exhaust down the side. FUel filler goes over not under the chassis rails. You can use the sierra overflow/fuel tank surge tank instead of the vit attached tank which will allow you to mount it higher out of the way. You will gain about an inch doing this.

LOL v840 - No it doesn't always work. But who said you have to ask! You're feeding the poor fella the wrong info....

If you use stock engine management don't run a rising rate regulator, the stock regulator will be exactly what you need and what the car was mapped around.

running a rising rate reg with stock management will just create a dog that overfuels under power.

rising rate regs are really just a cheat to get around correct injector sizing. If the boost is stock, there's no need to play with anything.

Dank
thanks but sorry the tank has already been fitted its from some small jappa with in tank pump. The pump is to small for a ZE as it wants lots of fuel and the surge tank is because i tend to play on "intresting" angles.

I have no god dam idea what you are on about but thank you

Posted: **Tue Dec 16, 2008 8:37 am**

Dank was suggesting the need for a rising rate fuel pressure regulator.

a rising rate regualtor is a tuning tool that increases fuel pressure more than boost pressure to run the car richer under boost.

They are generally a crude solution to a car that is running more boost than the stock computer knows how to handle.

There should be no need to fit one of these as the factory toyota engine management is designed to work with the supercharged engine.

In relation to surge tanks - I still think they are pointless, smelly, leaky, complex bling. I've never seen a car with a vitara efi tank have any sort of trouble at any sort of angle, and a GZE will only use 120Kw worth of fuel, so a GV or XL-7 pump would be fine.

That's my 2C though and if you've already got it there's no point ripping it out.

the injector sizes are quite a bit different
"gze ones are 365cc from memory and the 4ag 288cc"

I have been told by a very reliable sorce i need to get as much fuel to them as possible and the best way is the dunny door pump.

We will agree to disagree on the surge tank

Posted: **Tue Dec 16, 2008 10:22 am**

Yeah 4AGZE injectors are 365cc, but the GE ones vary from 182cc (dark grey) to 250cc (violet). There is no 288cc GE injector.

A good GZE injector upgrade would be a 430cc (black) from a 7MGTE or 3SGTE.

Posted: **Tue Dec 16, 2008 10:41 am**

muttis3lV6, I'm a bit confused. are you building a GZE out af an NA motor (or something), or do you have a complete GZE?

If you have a complete GZE you don't need to stuff around with injectors, fuel pressure regulators or anything - just put it in, wire it up, and enjoy the quoted power and torque with stock drivability.

Why are you asking about injectors? what's wrong with the injectors in it now?

I don't know what "wants lots of fuel means" or what it is in relation to injectors? pump? It only needs 120kw worth of fuel- ANYTHING from a commodore would be miles and miles big enough - Even a 10 year old hilux makes nearly as much power and more torque- so it will have about the same fuel needs.

I think you are trying to make this more complicated than it is.

Steve.

Sorry my bad the point I was making was that a ze injector is bigger than a ge injector. I bought a complete ze and am not planning to mod it in the near future.

I knock around with a couple of Toyota nuts and if I need advice regarding the engine I talk to them, unfortunately for me they have never tried to put one in a Zook hence why I ma asking questions here.

They have told me very clearly that it COULD be ok using a standard fuel pup but recommend I get a higher flowing pump from either a turbo RX7 or a dunny door.

I don't fully follow your theory on power output has anything to do with fuel input as an inefficient engine will require substantially more fuel then a well set up on. BUT its off the subject and dont matter

Posted: **Tue Dec 16, 2008 11:14 am**

engines consume, in general 5g of fuel per KW per minute.

in imperial - it's 0.5lb of fuel per HP per hour. the actual figure varies between 0.46 and about 0.54 lb/hr taking into account architecture. Unless your engine is running massively rich, those figures will hold. The actually work for a Sierra at cruise and for a Bugatti Veyron at 406km/h

That's for an engine at stoich.

when you say a "standard" fuel pump i don't know what that means. I assume you mean a standard pump for a 4AGZE, and you will be fine with one of them, but a commodore pump will do the job fine as it can support more HP than the GZE requires.

There's no such thing as a "standard" fuel pump as fuel pumps are sized for the pressure required at the flow the engine can consume, which is linked to their HP.

Now back to the point of this post

Where in Brissie are you? If you are anywhere near Everton Hills or don't mind driving there then go and see Brewskibilt. He has a LWB in pieces at the moment that will be running a 4AG-ZE. He doesn't mind chatting either and I'm sure if you turned up with some liquid he'd be more than happy to answer questions.

Posted: **Tue Dec 16, 2008 2:48 pm**

Its about 20 min from mione so perfect!
Can you pm me his detals as serch says he dont exist

Thanks heaps!

Ijust got this 82 zook with a 4AGZE fully installed and mod plate for QLD. But I live in Sydney. "Man does this Zook fly"

Because it is in an early model without a brake booster it is a bit scary to try and stop, but i will install boosted brakes soon to fix that. The that I liked about this zook was not only the conversion done, but how it was done. Everything looks neat and works, even the jackshaft and refab tranny/gearbox mounts. It runs a surge tank and MoTec ECU, thermo fan etc. I just got it so I am still learning more about the car.

Grrr why are you not in Brisbane so i can look!

Do you know if its a standard Serria radaitor?

How are you plannign to fit the break booster?

What sized exaust is it running?

What is the hole inthe bonnet for?

i have had quite a few GZE and GTE's and they dont like running anything but standard pressure. rising rate aftermarket ones are pretty useless on them.

the GZE can be a pretty thirsty motor, they do use above average amounts of fuel but you get that with supercharged engines.

Posted: **Wed Dec 17, 2008 6:38 pm**

Thanks Adsport
What did you run the ze in?

Posted: **Wed Dec 17, 2008 6:51 pm**

the one i have in the moment is in my AW11 MR2. it has a fair bit of shit bolted to it . ive been playing with 4A's in their various guises for about 5 years
