Maybe have a talk to these guys?
STM | Speedtech Motorsport - Performance Vehicle Specialists - EVO 1-9 | STi | HOLDEN | Nissan

They know Links inside out, and might have some contacts in the states that could be of help?

They've tuned cars all over the world, if you're lucky, you might be able to get in touch with Andre next time he's over there? Not sure when that would be though

 

Is the Avos twin screw not suitable?

 

Thanks to both of you - I'll contact the Kiwi's for an opinion
- I am in Townsville Australia, the bloke that does my dyno is the world distributor for both ECU's - but even after all of his reassurances - I want my trip computer and cruise control, I just got an email from Avos with a link to a British company, who may have one sorted. I just need to hear from somebody that it is achievable.
Some of the existing mods to the car are.
Twin screw
3 1/2" cold induction with Abaco MAF and bored throttle body
modified intercooler heat exchanger and pump
blue printed heads and ported induction
Modified twin in - twin out fuel system - with fuelabs regulator,plus a kennebell BAP
Nameless 200 cell cats and 2 1/2" quicksilver exhaust
This rebuild I am using a 4.2 litre block (forged) plus Carillo pistons, 650 - 750cc injectors an exhaust header system and hopefully a fully programmable ECU
the attached photo is one of the destroyed blocks
