Hi guys, I need some advice. I have found some very special air horns but the length is 100MM. I will be running a Kameari intake manifold (regular length, not short) with 40 mikuni carbs. My car is stuck under snow and I cant go out and measure. Will the air horns be too long? Thanks Edit: My car is a USDM vehicle. These air horns are for JDM vehicles and their brake masters are on the opposite sides.

Just arrived from Wolf Creek Racing Todd has done a fantastic job with this new addition to my car. I'm really stoked about getting these on and the car fired up. All soda blasted and ready to set the idle and sync. Pretty close to a plug and play install. I'll be removing the current mechanical fuel pump and adding an electric one along with a pressure regulator to maintain fuel pressure at 3 +/- .5 PSI along with a heat shield and triple fuel rail. The jetting setup is: 40mm Mikuni Carbs 32mm Venturis 40 Pump Jets 57.7 Pilot Jets 150 Main Fuel Jets 190 Air Connector Jets Hometown elevation is 3200 feet Hope to install over the weekend - stay tuned for fur…

Hi, I have just begun restoring my grandfather's 73 240 (that I grew up driving too) and I wanted to upgrade from the round tops to the dual webbers. I have the chance to get a used pair without the linkage. How hard is that to find or can I use any of the SU linkage? Any help would be great. Shaun

These pics were taken in Japan at a Fairlady / Z car show. These covers were probably produced in Japan. Anyone know where I can pick one up? I've seen the one available from Borla-TWM and it's nice but not in the same league as this one. Thanks, Chris

So after looking around for while for an air filter system for my Mikunis I have decided to make a cold air intake set-up instead. There seems to be very little choices for CAI for triples-make your own or pay 400$+ for a TMW fiberglass box. Being a cheapskate and a father with bills I have decided to take my time and make my own-with a twist;)--I'll elaborate later. For now, I have been lurking around and seeing what else has been made by my fellow Z'ers. It seems that SS is the material of choice for a heat shield, I guess because it doesn't transmit heat as much as aluminum. For now I have made mine from aluminum, but plan on using a some kind of heat barrier material…

Got my Triples back from Todd last month. Here's a shot of them when I bought them, and a shot from when I got them back from Todd. They've come a long way. These 44's are going to have their work cut out for them in the Spring.

I am thinking of making an intake manifold for attaching a single 50mm DCOE weber. It would simply replace the two SU's. I am just at the concept stage and about to buy the 50DCOE....any suggestions/input on how to optimize the design or (been there done that) is most welcome. I do not think it will have any performance benefits but it should be more tuneable.

My set of triples are OER/SK's (Weber clones with a few refinements), just wondering how it is determined that a set is 40's, 45's or 50's. Is the measurement taken at the narrowest point near the butterfly valve or at the front where the air horn attaches? I ask because I would like to purchase a set of air horns and those cool SS mesh filters that snap over top. Carbs Unlimited (thanks Zedyone_kenobe) sell them as well as Peirce Manifolds but they all seem to come from one maker. They say they filter down to .009" - is that good? Is that enough or is it only for car shows? I love the look, but I don't want to sandblast the insides of the engine for looks, I want the en…

Source for new nissan SU floats? Called Bruce, ZT has some used ones, then called the local shop and will drive over there to get one, also used I guess. But nowhere to order a new nissan float? MSA (catalog shows it for $17) is out and doesn't know if they'll have them again. Zcar AZ lists it for $120 (what !). NAPA online shows a kit for the 240Z (yeah right) with a trainload of gaskets but no float. Autozone gave me the cross streets for a possible. Come on Nissan, cough up some damn floats. My front carb is way lean due to float setting which I might have messed up previously. The float on there is a type that's hard to adjust. Can't get it to sit level withou…
