I recently got my hands on another NZ GT4, it seems to come with the same specs as the rare WRC versions. But I was wondering whether the NZ versions come with a steel turbo or ceramic, does anyone know? it's the ST205 version.

Cheers.

Pull off the turbo and have a look in the exhaust housing. Its pretty obvious if its steel or ceramic

by **ThePretender** » Mon Jul 19, 2004 5:44 pm

I would but I don't know sh*t about cars, so I don't wanna screw my GT4 up! I was thinking of getting the boost wound up a little... but don't want to go to high if it's ceramic.

Have a look at this site for some info. If your car is an NZ new GT-Four it should be a Grp A, with all the homolagation extras and should have a Steel CT20B although it isnt mentioned on this site(sure he just missed it out).

have a look at this site also, has some more info

Yeap only JDM models came with ceramic turbines, all others came with steel turbines.

Wanna swap turbos and some cash The Prentender?

by **ThePretender** » Mon Jul 19, 2004 11:13 pm

cool thanks for the help.
what do you guys reakon is a 'safe' level (without blowing it up!) for winding the boost up on a steel turbine?
Don't worry I ain't going to make the same mistake I did last time! this is for track use.

nah sorry man, if it wasn't a steel turbine I'd wanna do the same thing!

Website · by Al » Mon Jul 19, 2004 11:16 pm

Yeah i have a ceramic ct20b, i think ill just push my luck for a while

by **ThePretender** » Mon Jul 19, 2004 11:20 pm

GT4-SUM wound his boost up to 18psi and blew his up, so don't push it to hard... I heard it was an expensive lesson!
Anyone know what a new steel ct20b turbine sells for?

Probably about the price of a custom stainless manifold and aftermarket Garret ballbearing turbo.
When I bought my ST205 it was running 1.2 bar on the ceramic turbo and had probably been doing so for some time and is still running 1 bar or more on a daily basis as far as I know, you should be 99% fine running 1.2 bar on the steel turbine but should really do a full exhaust system first.
As for Al he should've bought Diss1dents old turbo before I did :wink:

What colour is the car? Confirm it is the Group A model as stated, then check here:

http://gtfour.supras.org.nz/history.htm

There were only 5 NZ New Group A models (I have confirmation from Toyota NZ).

Anyway, NZ new is steel turbine. Mine runs up to around 1.25 bar on rare ocasions (fuel disappears rather fast but it goes like stink).

There is photos of both steel and ceramic CT20B turbines on my site.

by **ThePretender** » Tue Jul 20, 2004 2:49 pm

Strangely it's exactly the same colour as your GT4!
I checked that link that Zomb posted- http://www.st205.net/techinfo/wrcornot.htm and my car appears to have all the Group A extras listed on this page and your website.

It was first registered in July 94' and the chassis says it's number 5336.
I know that the first 2500 are suppose to be WRC/GroupA cars, but maybe Toyota keep manufacturing them at the same spec for a while.

This is strange... maybe there are more Group A cars around then just 5

give me the full model and frame numbers, i can tell a few things from that.
but so can you... if the model number is st205r then its most likly a grp a.
the 'r' denotes a rhd drive vehicle destined for export countries

Huh? You are right that the R means right hand drive, but all that tells you is that it is right hand drive! All ST205 went down the line together, so Group A were intermixed with non Group A (which is why some Group A models have higher chassis numbers.

I have a letter from Toyota NZ stating that my car is one of 5 Group A models destined for NZ. I can copy it and maybe someone at Toyota can confirm for you.

Given that engines can be swapped, I'd say that the best way to really confirm is to check that the washer bottle has the three pumps on it, one for windows, one for headlights and a big grunty one for the IC sprayer (wires not connected). Does your car have two small vacuum tubes run from the dummy cold-start injector on the plenum (another Group A part) into the holes in the engine bay sidewall beside the brake master cylinder? These tubes run down to the IC Spray system and will not be on a non-Group A car.

Maybe the 5th Group A was actually blue, not white? The registration date is certainly about right (I think mine was June).

by **ThePretender** » Wed Jul 21, 2004 10:12 am

I'm honestly no expert when it comes to cars, so it's prob best I just show it to someone who knows more about this stuff then me!
I had a look at the water pumps, the bottles seem to be hidden away somewhere in there and it's hard to check the pumps. I did have a 96' NZ new GT4 before this one and I do remember the pump setup being different to this.

Do you have any idea how many NZ new GT4's were brought into the country in total? is there anyway to find out?

by **Mr Revhead** » Wed Jul 21, 2004 11:30 am

You are right that the R means right hand drive, but all that tells you is that it is right hand drive!

it also tells you that the vehicle was not sold in japan, all jdm model numbers normally have no letter after the initial model number, the exceptions are wagons and vans and the odd car, eg the st185h which is the rc version. examples of those are lh113v (hiace) ae115g (carib)

so if you have a model with say st205r then that is more than likely a nz new version. it will definitly NOT be a jdm vehicle, but it is possible that its been imported from another country. 'L' is for left hand drive
