Hi Martyn
Out of curiousity, are the turbos all the same or is the A/R ratio variable depending on the amount of boost required or is the maximum boost capped by the waste gate. Is it water cooled as well?

Well done Martyn. Hopefully you're about to get a return for your doggedness and perseverance in pursuing this goal. Time, effort and money aside should this all come together you will have done a great service for all us OKA owners.

On another note, I drove a cable shift LT OKA several years ago and its gear change was silk smooth, I couldn't believe it was the same gearbox as in #413. Whilst I have heard some negative reports of this system I can only comment on what I found. I was very impressed and would gladly install one in #413 if there's one for sale somewhere :).

Peter the Turbo was designed to achieved 20 +. The boost is not achieved by the Turbo alone it requires Turbo, injector pump, injectors,inter-cooler,air in and exhaust out all working together if one or more are not functioning correctly or not suitable then however you try you wont get the boost you want having said that the waste can be set to bleed off as you want so set it for 18 and boost of 18 achieved the waste-gate opens and exhaust starts to bypasses Turbo so you dont over boost.
All Turbos are the same however the A/R ratio can be changed if you require but as these were specificly designed for the OKA and the space available new moulds made cast and machined etc it would be a big job to change the ratio now.
I hope this answers your question.

Yes. Earlier posts were talking about turbo pressures and age of motor hence my query. I assume it isn't water cooled.
I have a LT with about 400k on the clock and are keen for one. How do we pay the 50% deposit? The cable gear change also interests me.

Even if the waste gate is set to 18psi you can put a bleed valve in the waste gate pressure hose and get more boost if you can get enough fuel.

Peter no it is not water cooled for a few reasons available space however get cable and it frees up a whole lot of space.
Payment will be via bank deposit which I will pass details to each of you when I have final numbers as this will determine final price.

Hi Dean The secret is to know when to give up and believe me I nearly did,if this one didnt give what I wanted I would have been so pissed off.

The cable shifter was not something I was looking at someone else is though.
I will probably get involved but I have to ask myself is the cost,need or desire worth the effort.
As you know I have not done anything about body work its been about mechanical and drive-ability and comfort, get me there and get me home so next project is body.Who knows I have been toying with the idea of 6 speed G/box

Martyn, yes, sadly the Fatal Error problem is caused by some incompatible software that's crept in to the system over the past year or so.

I'm in contact with James and we are working on an upgrade plan (yes I know you've head that all before) and we hope to be able to make an announcement soon. Unfortunately there are only 2 of us now to progress these things.

For anyone new to this problem, this post provides a work-around.

If you end up accidentally double posting, no problems, I check for duplicates and delete any I find.

The Turbo Update topic is "Trending" as they say, so I've extracted all the text (excluding a few admin comments) into a single pdf file which makes it a bit easier to follow and read off-line. (Right-click to download).

I'll update it as new info is posted.

Also some useful info on the ThermoGuard website in the Technical Info section.

Nice work, Martyn.

Where did you find a dyno that would test an OKA?

I really need to drive a bog 110 Perky to see what all the fuss is about.

Cheers, Tony

.......delivery to DHL depot in Perth........


Hi Martyn, on a different note. DHL has a history Of charging 'customs inspection fees' on imported goods. It is really nothing of the kind but instead a profiteering scam in which the importer is held to ransom before their goods are released. There was a good thread covering this on the AULRO (Landrover) Forum a couple of years ago. At the time Customs were adamant that these additional fees had nothing to do with them and were pretty unhappy that DHL were gouging importers and blaming it on Customs.

I've avoided DHL like the plague since this and used TNT on the odd occasion when I've imported without problem so I am unable to say if DHL still following the same 'process'. Definitely worth checking with DHL before committing to them.
