I'm looking to series-charge an ef12 much like what has been done with Nissan's Mirca super turbo. My question is are there any super chargers that are known to fit an EF12 with relative ease? I have read this thread for assistance with the turbo, subarujusty.proboards.com/thread/2114/1989-subaru-justy-4x4-turbo, and realize that much modification will have to be done, but it is feasible as long as there is a supercharger out there. Here is a link to Nissan's ma09ert engine specs for any who are interested. It's a fantastic little car reminiscent of our beloved Justy. In fact the Mirca was created to compete in the same arena as the Justy. en.wikipedia.org/wiki/Nissan_MA_MA09ERTAs a proud Justy fan I cant let it be out done.

What exactly do you refer to when you say series charge? I'm unfamiliar.
There is nothing that will fit the EF12 "with ease". The EF10 is it's only relative and it's essentially the same motor - and never came with any bolt on power increases.
And anything is possible with enough time, money, and motivation.

Series-charged, or sequential compound charged, refers to a modification wherein you install a belt or chain driven supercharger to increase low-end torque and an exhaust driven turbocharger to increase high end torque(supercharger plus turbocharger). The utilization of the supercharger also reduces turbo lag time making for a wider torque range and power-band.
Basically when the back pressure reaches a certain level a valve shifts and the turbo takes over for the supercharger and vice versa making for a constantly pressurized aspiration. There is more to read on the ma09ert wiki page if your curiosity has been piqued.

this is also called twin charging.
when i first read this i thought you meant where one turbo feeds charged air to another turbocharger to re-crush the already pressurized air. Diesels used to do this. I THINK its called parallel turbocharging.
a belt driven turbo AKA centrifugal turbo will do nothing for you on this car to get low end tq. youd have to use a roots or other positive displacement type blower to get that sort of grunt. the bent driven turbos are really rpm dependent and work much better at high rpm and on cars that revv high.

This guy did it. Although it would seem the pictures have stopped working.. It was an EF12, would a small blower/supercharger and a turbo. Terry
