Hi all, I need a little help. I came across some 44 triple carbs and wanted to know if they would be too much for my stock l28 at the moment? I would really like to use them so any help would be greatly appreciated.

I had rejetted 40's on my L28 and I was told 44's would be better, just could not find any at the time. I loved the sound and performance difference. With the 40s I didn't even have to change my cam. That may be something you will need to do. Even if you don't use them now, get them if they seem to be a deal. good luck

You can use them on a stock L28. The useable powerband will move up about 1000 rpm and the engine will not run out of breath like it does with 40s.

what would be a the right jetting for a stock l28? here is how the carbs are set up

200 Air 150 Fuel and 52.5 Pilot. Venturis are 34MM

Mine were jetted 200 air, 132.5 main, 57.5 pilot, 40 pump; with the same venturi size

I would agree with Curtis' jetting for a stocker. I don't have access to my 44's right now, but the main jet on our 230+ HP Bonneville L28 was 145 or 140 depending on altitude. I think mine were 135's, with either 200 or 220 airs, and 57.5's on idle.

Most people add main jet to overcome cruise popping, when in reality up to 3000 rpms and light cruise you're actually running on the idlejets in the Mikuini! 57.5 or 60 is not uncommon when properly set up, with a corresponding decrease in main jet size and great leap in fuel economy. I would routinely run mid 20's on the highway with them, and that rarely varied unless it was a track day (when I could drop into single digits).

Likely a set of idles and mains and you will be nuts-on correct for a stocker.

With 40's on an L24 I ran mid-high 20's for highway cruise (sticking to 65mph) and on occasion when in states that restricted me through pernicious enforcement presence to 55-60 I could crack 30mpg!

Which would be the better choice in 240z triple carb set ups, Mikuni 44's, or Weber DCOE's?

Not sure i would like to know this also...

Plus what is a good price for 44 Mikunis? Say if they are "like" new with new manifold and linkage?

$1500 to $1800 I would guess

so if you guys could get some like new Mikunis for 1500 or buy new 45 webers what would you go for?

I like Mikunis better. There low speed metering works very nice. Once you set them, you are done. No constant fittling with them. Plus they have a vacuum port for your distributor. Unfortunately Mikuni no longer makes complete carbs for cars, so whatever is already out there is it.

BTW, the Mikuni manifold is not ideal so don't buy it if it is a choice.

whats wrong with the mikuni manifold? the one im looking at is the short version?
