Default Carbureted street 944?

I know it's been done on a race car, and I've seen a few 924s that have been carb'd. Just wondering how much of a nightmare it would be to carb a 944. Or would it be fairly straightforward?

A few years back I was involved in converting a 92 Civic Si to carbs (oddly enough it made more power) and a friend of mine converted his Jag XJS to Carbs. It'd be a fun project for my parts car.

Why would you do that if you can have a standalone ECU for the cost of carbs and result is more power and car that you actually can use?

itd sound cool, but wouldn't be so good to drive and your MPG would dump.

Idk, by tuning carbs you could probably get more power and the throttle response would be much better plus no electronics is a plus in my book especially on a track car.

ECU'S are only good if you can tune them, our dated ECU is rather difficult to work with in that respect.

U get a late car DME and chip it. Rogue tuning has this down to a package you can get. Carbs are just cool though. Would be great to have a few Carbed 944s runnin around. Instead of saying factory or only this way is best, I'm interested in seeing other setups.

Rogue does a great job but chipping isn't tuning. I'm talking about jetting carbs dynamically on a dyno, old school...anyone remember those days.

I remember those days. I converted my 280Z from Bosch L jetronic fuel injection to triple dcoe webers. It was far more adjustable, and adaptable to modifications. I got very very good at working on them, and could easily fine tune the car for different applications which a standalone ecu can do much better, though back in the day a standalone was $$$$$ Carbs are still relevant for all out performance, but by today's standards are like using a pipewrench instead of a 12mm socket.
They have a great "GeeWizz" factor going for them, and look very impressive under the hood!

Its tuning, no different than with a carb setup. You tune your fuel curve to get the right A/F ratio on the Wideband. If I still had a carbureted car, I would be doing the same thing using a wideband and a dyno. Rogue Tuning also uses a dyno to get things right.

They chip it so it can be tuned is my understanding.

Haha whenever I bring up carbs anywhere no one's ever neutral on the subject.

Me and my buddies were just tossing around the idea as something to try on my parts car. We had a blast trying it out on an old Civic. Sounded amazing.

It'd be neat on an early car, and it'd match the old school style.

I would love to see some pictures of that car. My family has a '73 240Z. Absolute blast to drive.

Well, sort of I suppose, they are tuned for a set configuration. If you change anything you will need to take the chip out and get a new tune burned on to match the changes.

At least with twin choke webers or the like you are basically running a dynamically tunable ITB set up, relatively easy to do. As anyone has ever tired to tune ITB's with a electronic/ECU will tell you, it's like voodoo magic, almost impossible to get right.

How about fuel injected ITB's running a standalone? I think with a cam and other supporting mods that could be a killer setup.
