Will the 3ct turbo be enough for low boost on the 3rz. On simular forums a significant gain in torque can be gained by adding an low boost turbo or supercharger to a standard 3rz engine. No added fuel consumption to be gained as long as long as u dont add weight to your right foot due to an adrenilen rush to the head. Is there somebody that has done this and what was your success or losses

I'm sure it's all been done before but can't recall anyone here having done it. The 3RZ is a notoriously tough and reliable motor, so I assume that for the best part it should be able to handle it and with the correct re-mapping should give significantly more power and thus better fuel consumption, if as you say you keep control of your right foot.

One thing bothers me a bit and it's common to most motors today - they're built so compact that the amount of meat between the cylinders is very small, and with the higher compression achieved and this already being a weak point in the gasket might tend to blow with standard gaskets.

I would personally be more inclined to go the route of supercharger rather than turbo, and as you say, keep the 'boost' on the lower side.

Need as little as 5psi boost. Have a 3ct already in my bakkie that went. Difficult to get spares for it so i can use its turbo.
