Hopefully I can cover everything for you with my answer here; the coolant pressure is unaffected by Twin Turbo install, we maintained healthy operating temps for the engine, and at this point, saw no need to upgrade the radiator or any other coolant accessories on the motor. We did however, install an external AAM Comp Oil Cooler on the car, to keep the engine oil temps down on hot days or during track use.
The factory VQ37VVEL engine is a very stout, adept motor from the factory, capable of easily supporting over 500rwhp. At these conservative boost levels, there really isn't much concern about lifting heads, so factory head bolts, head gasket, etc. were left untouched. We didn't even go internal much at all really; just a basic Twin Turbo Install. The customer wanted a car that would perform well on the track, but more importantly, he wanted the car to look and feel like factory on the street.
In addition, the 370Z engine is actually
not a push-rod type engine, it is a traditional Dual Overhead Cam. The factory pistons and connecting rods will be strong enough to support the cars power output at the current boost level settings, thus internal engine upgrades will not be necessary until the customer requests higher power output and higher boost levels.
