Has anyone ever tried to put one of the Redline dual downdraft Weber kits for a 240z on a 2000? Any input appreciated

I don't think there is enough room under the hood for a dowdraft setup.

I saw a Roadster with dual DGVs on it once upon a time, but I think the J-shaped elbows that bolt onto the intake manifold were smaller than the Z ones. It was on a 1600 so they might need to be ported to flow properly on a 2000. What about using DGES (38/38 synchronous) instead of a DGV carbs? Anyone got a spare DGES lying around? I want to replace my newly acquired DGV on my 411.

UPS just got here, let you know in a few hours

DAMN it is SO close...If I didn't plan on using the hood, it's a bolt in. Top of the air filter is level with the fender bolt heads. If I had a TIG welder and a milling machine, 1 hours work would do it. Carbs are about 10-15 degrees off level but otherwise clear everything can even get the master cylinder in and out and the linkage and chokes wouldn't be too bad to hook up.

I'll give it a fresh look tomorrow and make a decision, but I do have a perfectly good set of SU's, so common sense will probably win out. Shame, would be a real blast to have a "four barrel".
I'll take pictures for posterity, looks cool as hell.

If anyone feels like a chalenge, give me an offer. Other wise it's going on Ebay and hopefully break even.

I have seen photos of a 2000 with one of those conversion sets, so it can be done. The info that I have read is that they are not really ideal. The airflow has to go in some pretty convoluted path, so fuel drop out and intake velocity are issues. Performance was down as was mileage iirc.

Now, if you really want to get wierd, there is a guy out there with a U20 that has a holley 4bbl bolted to it. I have no idea where he got the manifold, or how it works, but it was odd...

I'm having the same thoughts. Think they are going on Ebay. SU's are nice and mileage is good.
A single progressive weber on a short runner manifold would be nice, they have a nice kick when the secondary opens. Had one on a Pinto 2.3 liter powered MGTD kit car. Talk about street legal go karts. I think it weighed less than 1800 pounds.

If you want to do a down draft, check an L series manifold. I belive that the port spacing is similar, so a creative machinist may be able to make it work for you. Offy and others made some custom manifolds too.
