Or port them to the size of the Nissan supplied STD single manifold gaskets. or about $2000 doing it yourself.Įxhaust manifold DTX low mount nothing else or if you want to save a few dollars on a std unit you can port the manifold ports to about 2 mm larger than the head exhaust ports. Probably $3000 if you get it done to my spec. I am bias due to having tested many types, a well set up water to air is the best no question not crap no argument its not even comparable if you value air temp stability which means better torque curve better cruse speed response or faster 80 to 120 klms passing speeds or slow speed 4 wheeling, well just about every condition its just the best. You need a cooler it doesn't matter which one as long as it is biggest you can fit.

Obviously at least a 50mm lid lift on your intake manifold this adds response and help distribution for reliability and adds cruse torque response because it allows better cylinder filling. This isn't about air flow this is about air speeds and not restricting your induction system to your turbo for instant spool ability which means instant torque at cruse speeds or 4x4 wheeling hence better towing response when you need it.$600 Fatz unit or simular.

For example airbox a ZD type just doesn't cut it for a ZD30 and hasn't a chance in Hades of satisfying a TD42 at 150rwkw. Now to make all this torque it is a whole lot better to drive and flexibility and fuel usage if you spend the time on the detail. At 150 rwkw this is medium power and probably has no real significant bearing on engine life on the TD42. Obviously this needs a tricked up 11mm pump or a 12mm element pump to achieve this with ease. Firstly You cannot get torque without Kw's but from my perspective it isn't very hard to get 150 rwkw and 600nm this seems to be the figure that makes the 3 ton patrol wagon feel fun and flexible to drive and has enough cruse speed torque and Kw's so you just don't feel a 2ton trailer in tow.
