The reason I fell in love with the FD was not just because it produces big horsepower for the engine size. It is still way quicker than MOST of the ricers 4cyclinders, it handles absolutly awesome (how many other cars pull 1g on the skidpad) and it looks so damn good, I mean park a tricked-out rice burner or a hopped up v-8 next to a sick *** FD and see which car gets the most looks.

And IMHO I would not turbo a renesis if compression is 10:1, sure you COULD do it, but why? Lower compression engines are better for turbo charging. Whatever detonation resistance you gain from the lack of EG recirc and better port design, you would lose by dangerously high compression. So you turbo a 10:1, engine how much are you planing on boosting?? 2lbs would make your final compression 11.4:1 (I guess you don't really like pump gas)

to it seems that a rotary needs lowert compression for a turbo than a piston engine but i agree that the renesis will be freakin awesome. T2's have 9.0 comp right? well they use only around10 psi boost vs. a piston with 10.5 is about 7 psi for the max

It works the same for pistons and rotors. And I would be more hesistant to run higher boost on a rotary due to the catastrophic effects of a detonation.

A 9:1 rotor at 10psi has 15.12:1 final compression. A 10.5:1 piston with 7 psi has 15.5:1 final compression. Any turbo engine must have lower compression to run any appreciable amount of boost.

just my $.02

Does anyone know what the Renisis engine rotors themselves are made of??

What makes a rotary expensive is the rebuild procedure. It's kind of like heaven and hell. A piston motor will take much more abuse, however when it breaks, it's going to cost you, but be much less expensive as far as labor goes. Most of your money will go into parts. The fact that you'll have less parts to pay for is the 'heaven' part.

'Hell' is the fact that it strays from the conventional motor. Anytime you have something different and rare, it's going to have less knowledge behind it. It's easy to rebuild a piston motor, you can do it in your backyard. However, the complexity and difference in the rotary scares some people away, and this is what makes the good builders so hard to find. When you have a good rep, you can basically charge whatever you want.

ROTARY are wonderful engine. it got a less moving part and REV super fast and smooth. way back in 60, this was the fucture. here in the 2003. we got all new rotary again. the engine spine to 9000 RPM all day long with out any fault( watched those japanese video) the only thing lack is TQ. that why kill rotary. that why MAZDA add turbo in the first place to add usuable TQ in street driving.there is no replacement for displacment when It come to TQ and MAX power. but ROTARY engine car are design for corner, not strip. I will like to see the new RX7 gick *** on those FAT *** COUPE .


MAZDA did not build new engine for RX8. there will be more to come
