I have imported a 2008 SEP3 RX8 6 speed 48k RHD Auto. The limiter is set at 8300 rpm. The gear change is on the steering wheel. I know nothing about the car and everything is factory.
I am also a new member to the forum so I am as green as it gets.
What is the suggestions to wake up the 13b factory engine. The previous owner treated like a baby and it crawls like a baby. Its hardly walking.
In many of my engine builds I have supercharged and turbocharged many of my engines.
is it as I am reading that the 13b SEP3 engine is a bad candidate for forced induction.
Has anyone considered the Torque Amp Electric turbo which on paper looks suitable for this higher compression engine as it only makes 5 psi gauge.
With the swept volume displacement (roughly 2600cc displacement over 720 degrees) occurring at one third of a 4 stroke engine the torque amp should stay at 5 psi boost right to the limiter. See test done by Cleetus McFarland you tube.
What are your thoughts.

Welcome to the club. I would suggest read the new owners sticky as a lot of your questions are answered there but I will help you out a bit here.

1. The VIN tag starts SE3P not SEP3. Minor but I thought I'd throw it in there. You can also change the gears through the gear stick. The wheel also works just fine for changing gears.
2. If the engine isn't working properly, best to start with a compression test to make sure the engine is still in good shape. If it passed the compression test, you should look at testing and replacing ignition system components (coils,wires, plugs and starter).
3. FI is not really practical on this engine but supercharging seems to be the best option to me. You can do it but don't expect much in the way of gains. Especially since you have an automatic. They are generally shunned by the RX8 community. If you want to use this car for racing I would suggest selling it and getting a manual. For daily driving it's quite good though.

Hope this helps!

+1 make sure it's performing at its best in stock form before considering mods. These engines are running near the peak of their possible naturally aspirated performance, there isn't a heck of a lot you can do without getting super experimental.

On the flipside, previous owner problems often remove horsepower. Read the New And Potential Owners thread to get up to speed, and make a plan from there. Ignition and catalytic converter health are critical to maintaining the car.

Yours is more limited compared to the manual version. There is nothing you can do about that.

If you want to plan your FI implementation, you're better to work with engine CFM. The rotary has a wide range from 5g/sec at idle to 190ish g/sec at redline (for a 6MT). Not sure what the flow characteristics of that electric turbo are, but fundamentally it's going to hit the same side exhaust port shaped wall as any FI project on a renesis.

It might be easier to swap in a REW.

sell it and get something else,
turboing a series 2 auto rx8 will be a waste of time

And a whole lot of money!!
