Does anybody knows who manufactures a webber kit for the normally aspirated 944?

Andre

whats a webber kit?

I am sorry, I meant a weber carburator kit to replace the fuel injection system on a normaly aspirated 2.5 8V engine

Why use Webers? That's ancient technology and you'll get lower performance than stock even. If you've got extreme mods on your car to the point where the stock fuel-injection system can't be adjusted to compensate, then go with an aftermarket system like Electromotive, Motec, Haltech, Wolfe, SDS, etc. Even the basic SDS system from http://www.sdsefi.com will be light-years ahead of ANY caburetor.

Yeah,
I'd be interested in finding out exactly what you are trying to accomplish. Overall driveability will go down I think. Fuel economy will plummet.

My idea is to install a couple of double 48mm weber carbs on a normally aspirated 2.5 for autocrossing purposes. I think that flow would be increased giving the motor substantially quicker response coming out of corners.
Anybody done this before?

Here is the sight for what you need...

This will REALLY make you cook! I may be interested in putting together a group order.

Can't help you much, but I know it's been done on the 924 (not an "S" in this case). I saw a 924 at an SCCA regional at Pocono this summer. At first I though it was a 944, since it had flared fenders. It ended up being a 924 and was running webbers. Apparently it was better than the older FI used on the 924.

I left you a private message, but ignore it I found the website the 914 guys were talking about http://www.redlineweber.com/

All I know on the subject:

The 914 guys loose power when they try to convert from MFI to carburetors.

Tabor,

How about the extremely efficient systems displayed in the link that I posted earlier? I think that it could help burn the fuel very well!

both carbeurators and push-rods are ancient technology....

A well-burning mixture has numerous factors. Some of the primary ones being atomization and optimal air-fuel ratio.

Carburetors requires using vacumn, air-flow velocity and the vapor-pressure of gasoline to mix fuel. This can never create as fine a mixture as fuel-injection. The actual burning part is ignition and combustion chamber swirl, things that don't really care about how the fuel actually got into the chamber.

Maintaining the best air-fuel ratio for maximum power is an even more difficult task for a carburetor. It's a mechanical computer and it's not as responsive to altitude and temperature as fuel-injection. Getting an even 12.5:1 air-fuel ratio across all RPM-ranges at all throttle-position openings for maximum power is definitely NOT possible with carbs.
