My thoughts have been turning to more power, and I am far from convinced that I should do it... but maybe I get a christmas bonus!!

Anyway I have done loads of pricing and looking at (pretty much exclusively Ozzy) 1HZ turbo kits. But then I threw it to one of our suppliers - in Holland, and got back the following after some questions about where the kit came from:

"1) The brand name is Toyota, The kits will be build with original Toyota Parts, (no Australian parts will be used) The offered turbo is a low pressure turbo, the turbo boost isn’t more than 0,55 up to 0,6 bar. It will give an extra 35 HP and additional Torque of 30 – 35%,

2) Without fitting the boost compensator the engine will not run 100% when the turbo isn’t switched on (below 1500-1800 rpm).. The turbo is providing more air/oxygen to the engine, this will gain more power but only when the engine receives more fuel as well. The fuel pump must be adjusted to the need of the turbo. A standard fuel pump is providing more fuel on total the rpm range, but you only need more fuel when the turbo is switched on. Without the boost compensator, the result is incomplete combustion (black exhaust gasses) below 1500-1800rpm.

I have translated this from Dutch, hopefully it is understandable."


Now I am well aware of the risks of turboing etc and for sure would fit a pyrometer and a boost guage. But I have never heard of a 1HZ toyota based turbo kit - can anyone shed any light?

Hi Gil,

I assume it's All American Imports you are referring to! I know about several 1HZ engines they have turboed, including a few 105's for the Dakkar people. I know one guy personally and he is very happy with the result. I believe the price for the conversion is about Euro 2500,- including installation. I wouldn't doubt their knowledge about this subject. If it is not AAI, then you may refer to them for this.

Gil,

I can second that. If it's about AAI, there's no risks involved as Maarten knows his stuff. If it's not, speek to AAI.

Cheers Noel,
the kit was actually offered through an agency, but funnily enough I was just thinking about getting in touch with AAI - they supplied me a longranger tank which is super... Could well be that my contact is sourcing from AAI! In which case they are at least doing me the favour of not adding anything...
Will get in touch with George if I decide to go down this route,
Gil

But I have never heard of a 1HZ toyota based turbo kit

Me neither and you'd think it would have been known about by now, esp in Au. Would not TGS know? Or ask Stefano at Grand Erg - he's been down that road and these days runs a 78 in the Sahara.

Got a mail from All American, and sure enough the kit is from them, and comprises original toyota parts! Priced at Eur 1,600 plus up to 300 for boost compensator. Like Chris I am surprised it is not more known, but then I suppose the Euro tuning market for 1HZ motors is not exactly large! The installation looks very good - they sent some pictures of the kit installed in a 105. Anyway, it will be a project in the New Year as the 78 is no dragster and I was always thinking about it.

AAI have a solid reputation amongst LC owners as Roman has pointed out. I've been contemplating getting an intercooler for my 80 for some time and their advice on this and other things is spot on.

FWIW
