I am still getting stuff set to go FI, but I got the Cobb AP from MM with his maps and it was worth every penny.

You know what.... i think i'm not going to be all quiet like and say 'choose for yourself' and say..... turbo. go with the turbo.
rotary= high rpm
sc= high rpm drain due to mechanical drive.... (yes yes in theory only and only on paper....)
i just think that the turbo when done right suits the rotary philosophy better. I'm not a super hater. Pettit makes a GREAT kit. does a quick fix on that low rpm tourqe issue. i just like turbos more. turbo turbo turbo. just not greddy. esmeril or ptp.

but then again i'm just a nub casuing controversy.

Haha, yeah I like the kit Esmeril has to offer.... Gotta say.. The Dynos from it so far look pretty good.... But it's more about the TUNE than the turbo.. And I know very little about tuning..

CrazyStoo

yea, your're right about that one. tuning maps if for the rich and the experienced. if you want to get into tuning your own maps though just ask to be with the guy when you're getting it dynoed for the first time; and ask LOTS of questions. 2 reasons

A you'll learn
B if he can't answer you're questions he shouldn't be tuning your car.

i couldn't tell you squat about tuning. all i know is this... losts of smoke, to rich. (bad for the cat and the plugs amoung other things)

lots of heat, too lean. (bad for everything)

don't run a turbo without some kind of tune though. the increase air makes for a lean run right of the bat i'd think. but again. just a nub.

Well, since turbo incorporates the exhaust, I'd think it would be running rich off the bat... But yeah, I'm not sure either..

Um, no.

Do you know what a turbo does?

It increases airflow to the engine. You're basically adding more air. More air with the same amount of fuel means you have drastically fuel than air than before. That is lean.

The only way a turbo cares about exhaust is propulsion.

One thing not noted so far is that if you aren't very familiar with FI and you aren't experienced at tuning FI engines one factor that may be the most important is having a shop or friend nearby who has experience with the FI option you go with. There's no doubt that the region people live in greatly effects their choice.

If you are not looking for something specific in FI (ie. consistency across RPM, reliability, max HP, max torque, etc) and are only looking to upgrade your car for all the generic experiences 8 drivers have (track, strip, show, DD, autoX) then you are probably going to be happier getting something that either you or the people around you are familiar with. That will help you get the most out of your FI purchase regardless of what requirements for FI you want to emphasize.

Ah, so both FI options just bring more air? I had been under the impression that, since SC pulled more air into the car, then turbo must bring more exhaust in and re-ignite it.. Haha, I was wrong, and yeah.. I need to do alot more research before I make a choice. I do, however know a guy very locally that would probably give me a hand if something was up, or who could answer any questions I have. He installed his turbo kit on his own and is a member of the local 8 club here in B.C...

Once again thanks for your responses, each one is educating me a little more..

no problem tubingchamp, that's why we're all here. To learn and to discuss.

CrazyStoo

yup. difference between is that a sc is mechanically driven, usually with a belt or chain, turbo is exhaust driven. the exhaust only goes one way. out. what you may be thinking of is overlap in the older port designs where a small amout of exhaust carries to the next cycle. .... ithink.
