the trick on the line 6 l28

[sone]

i was walking to a cliente of mine and he was not very social, until the end of the deal and at the end he started talkign to me about my car (1977 280z) and he started to tell me about a rich guy back in the day that had ohne tricked out, but the one feature that stood out the most is he had put 3 carberators in it for the 6 cylinders, he said that small detail lets you keep everyhting original and and give you the power like a v8, if anyone has any info or specs of guides or opinions, please reply, i think i want to give it a try, the other thing is i have a l28 and i was wqondering if i could do it wihtout swapping to l28e

before you get flamed, ill jump in. those are called triple mikuni carbs. do a search on those and you should come up with plenty of information. just know, carbs are a whole diff animal than efi.

I don't think I would put tripple carbs on an L28e, fuel injection and carbs are two diffrent things.

Hi Welcome to Hybrid Z, one of the best Z sites on the web. The L28 is a very versitile engine that has many encarnations. The L28 was made for approximatly 13 years and because of this many, many modifications have been tried and experimented with. Any L6 Z engine block will work with any L6 Z engine head from any of the 13 years of manufacture. There are turbo modifications, tripple carborators, superchargers, stroker engines, and much more. The three carborators that your friend was talking about is most likely the tripple webber setup, but there is also a makuni, or SU setups also. As far as getting V8 power out of a the L28 the answer is YES. Keep in mind that there is no replacement for displacement, so the V8 will always have the potential for more horse power but the L28 is an exciting power plant with horse power verying from 180 to 450 to the Wheels depending on what you do to the engine. As far as the L28 vs. L28e goes there is no differance other than the "e" stands for Electronic Fuel Injection, all 280z's came from the factory as L28e engines. So if you wanted to make your engine into a tripple carb engine you would have to replace your EFI intake manifold with a tripple webber manifold/carb setup, I think they are selling for some where in the $1,200 range. I hope this helped to answer some of your questions.

Here's a pic of my Mikuni Solex triple set up on a N42 head (originally FI).

nice... anyone know the stats on how much of a difference they make? or in the case of v8wannabe2, how much of a difference yours made?

[v8wannabe2]

Sorry, can't help you with that one. I'm hoping to have the machine work done this month and get the engine together over the winter.

It totally depends on the rest of the engine. Triples work best with a much larger than stock cam, and that works best with high compression. I figure I gained about 40 whp by putting them on in place of SU's. I think Dan Baldwin had similar results verified by the dyno.

 

Just slapping big carbs on with a stock cam isn't going to get as big an increase, and you also have to figure that they need to be tuned to be optimized. Tuning them isn't really that hard on Mikunis, harder with Webers, but you'll find a lot of people chase their tail trying to get them running right. Tuning is somewhat expensive because of the cost of the jets as well, so factor that into the cost of upgrading.

on the bright side it's cheaper to buy jets as opposed to new injectors for a fuel injection system at least
