hang_510 Posted December 19, 2007 Report Share Posted December 19, 2007 I need to get some air horns for them that will fit between the carbs and the brake master ive seen the #4 horn cut to fit :( i have a dual master set up for the brakes (w/a bias adjuster) which allowed for the long mani/air horns inside 3" filters Quote Link to comment
VRTSid Posted December 19, 2007 Report Share Posted December 19, 2007 mikuni and weber are 2 different things!! I didnt think it was important but I think this is the style setup hes talking about being not a downdraft, right? Quote Link to comment
tiltnose510 Posted December 19, 2007 Report Share Posted December 19, 2007 Yes, that single setup looks like it would work but again an equalizer tube of about 3/4" would work wonders on it or an open plenum between the two. Quote Link to comment
DOM Posted December 19, 2007 Report Share Posted December 19, 2007 I got a set of Mikuni 44s with nissan comp isolators and long runner intake for $500 bucks and I know Troy just sold a set of BRAND NEW Mikuni 44s never even mounted on a car for 1100 bucks so I guess that price is ok maybe a little high if you ask me Yep, that was me who bought them 44's. I found Wolf Creek Racing has a set of NOS 44'S for $1000 also. I was going with ITB's but decided I would spend the money on other more needed parts. Quote Link to comment

T.S. you LUCKY bastard :lol: I wanted those bad but considering I have 2 sets of 44s and no more cash... well they went to a good home on another awesome project :eek: CARS LOOK GREAT by the way Quote Link to comment
banzai510(hainz) Posted December 19, 2007 Report Share Posted December 19, 2007 69FJwagon there was or maybe still is the single resivor master cylinders that were sold so you could run the airhorns. I just cut the ther last airhorn on a belt sander myself and called it good. Never actually seen short airhorns for a 44 mikuni Quote Link to comment

phatdave Posted January 22, 2008 Author Report Share Posted January 22, 2008 I found some tuning tips,I have some spare cash and I am goint to attack her and get it running, Still need good Transmission and some small shit to do it. I have 100.00 bucks for a 5 speed if anybody has one to sell. DCOE tuning tips:http://members.aol.com/dvandrews/webers.htm Quote Link to comment
Shonuff Posted January 24, 2008 Report Share Posted January 24, 2008 i got a single and i can tell you its great fun:D i have had a lot of tuning issues with a stock eng with it tho. theres too much fuel and air for the stock system to cope with. i really need a cam and upgraded spark to get it to not run rich but you could tune a dcoe to work on a stock eng, but thats gonna take a long time of sniffing tail pipes n plugs, buying and mixing and matching parts to get the right mixture. better off getting the recomended jets for your application, the manufactures assume that you already have a "performance" engine with upgrades, like a prerequisite. i do foul out plugs 2 and 3 alot :glare: Quote Link to comment
phatdave Posted January 24, 2008 Author Report Share Posted January 24, 2008 The info I put on above has a bunch of good stuff. Starting with using the correct size venturi for each application. That is the single most important factor. That basically changes the CFM of the Weber. From there it's a matter of following some basic formulas: Main Jet= Venturi x 4...so a 32 Venturi would call for a 128 Main Jet. Air corretor = Main Jet + 50, or a 178 Correction Jet. Emmulsion tube for a stock or slightly modded 2000c is a F16 or F2 Air Jet is 50/55. :blink: Quote Link to comment
Shonuff Posted January 26, 2008 Report Share Posted January 26, 2008 im not trying to discount your info, i have had that page bookmarked for @ least a year. if you want a tear down/repair manual from italy pm me your e-mail and ill get it to you. i was more trying to point out that i slapped it on and have had a lot of trouble to get it to run right. the DCOE is a race carb, not a progressive daily driver. my biggest mistake was spending the time to get it to work with my stock coil. i dont know about datsuns but a 30yr old toyota coil just isnt up to snuff to properly tune a weber. i use that link and bounce around the "official weber" sites for info http://www.redlineweber.com http://www.webercarbs.com http://www.racetep.com/webjettune.html bottom line that all the old farts ive talked to and most tech ive read is this: make sure the rest of your car is up to snuff for a racing performance upgrade B4 you begin tuning.
