N/A or Turbo

[Raksj04]

Does a N/A benifit from a higher redline then a turbo engine?

There's no need to raise the redline if the engine doesn't significantly make more power at the higher RPM's.

No. They use 4 port engine because its superior for power and torque production, no matter what porting is applied to irons...

Its quite strange question. Turbo engine is very same as NA engine, it just operates in different absolute pressures. Certainly, once you reach maximum torque you can produce in NA engine, only way to increase power is to carry this torque to higher rpms and high rpms=huge stress and wear on everything. So in case of turbo engine, its always better to turn up the boost then trying to spin it to the moon

To the OP, if your system will be really optimized, it could go over 250 HP@crank. That being said, most streetported 13Bs are probably making around 220 HP... It depends on to much things...

What would i need to do in order to run RX8 rotors?

A few things which aren´t worth a hassle given the fact, that RX8 rotors were already proved to be inferior to S5 NA rotors in any measurable aspect, mainly in power pruduction...

You don´t even need high comp rotors, great power can be made on lower CR ratio, you just tune accordingly...

Well a few things have been decided.

I'm going semi pp and with 9.7 Rotors, and all the nececary machining and parts to get it able to run high rpm's.

Depends on the port but typically turbocharged cars will make more HP and at lower engine speeds (just look at stock FC HP numbers). With accompanying modifications N/A power is increased through displacement and/or engine speed, which do you think is the easier to go after? That's not saying you can't have a 10,000 RPM turbocharged car but that's a lot of stress (and heat) on the turbo.
