Is this system available for the zd30 powered d22?
What sort of power gains are you getting from this system?
The D22 runs a boost control actuator on the side of the turbo and we use a single stage Electronic boost controller to control the boost on this particular car. We do a Diesel Smart module which plugs into each individual injector for this car, we can program the module for standard boost or we will program to suit 18 psi of boost.
With the D40 we run a diesel smart module which has been programed to suit our vacuum controlled boost system. If you go to our youtube channel you can see the setup we use.
Yes this system is available for the non commonrail zd30 engine in the D22 but they don't make huge power, that being said it is still very noticble over standard with about a 15-20% increase in power. We are limited by the pump and what it is capable of pumping without breaking the pump or shorting the life of it with this particular model.
The navara commonrail diesels pick up a lot more power and torque gains out of having our system fitted to them then the zd30 ones do.
In terms of pricing, the retail on these is $1390 but you can buy them off our online shop for $1290
