MFI vs Carbs vs CIS vs Motronic
 

just wanted to see what everyone thought of all the different induction systems out there...since I am in the planning stages of a rebuild I was thinking either swap out to a 3.2L with motronic or stick with my core and go MFI/Carbs

I know application is a factor...street...track...full blown race...

Being an SC owner I know the shortcomings of our environmentally friendly CIS...

So if you were building a motor...probab 70 street 30 track (or give me your own combination) which system would you want on your car...

MFI seems to get the accolades around here for being a legendary FI system used for the race cars...

In my opinion, carbs are the best option and the way I would go if I every upgraded my SC. The MFI is famous, but also notoriously hard to tune and keep tuned. For Motronic, you would need to pay for someone to map your chip, though I'll admit it shold be maintenance-free after that, unless you continued tuning. Carbs are the most flexible solution, easy to tune once you get the hang of it, and able to handle future upgrades.

My 2 cents,

I love my MFI and i think that the tunability gets a bad rap. Once you understand it, it isn't that hard to get right and when it's right it is a beautiful thing.

but...

For a larger motor you either have to be extremely creative with the stacks and throttle bodies you can get or buy some expensive high butterflies/ extremely expensive slide valves. The later two being very hard or impossible to mount an aircleaner on so they would be strictly track cars. For the money i put in my stacks and throttle bodies to get them big enough i could have bought a new set of PMO's. But i'd do it again because the throttle response is amazing.

Sorry to use up this space, but Mark (82SC) there's something wrong with your email. I've been trying to email you for the last 2 weeks and keep getting weird email errors (like your hotmail account is full or something). Anyway, I still haven't received the 993 (non-turbo) part that I had ordered from you. Please drop me a line at omar.villa@mail.bcop.com and let me know when to expect it. Thanks
