Has anyone here used one of these 4 barrel carb adapters http://www.zcarparts.com/store/merchant.mvc?Screen=PROD&Product_Code=11-2995&Category_Code=PFFC04

Anyone?

Do a lot of research before you buy this. Use the search and try any and all configurations, 4 bbl, arizona intake, single carb, holley and so on. I've been here for a few years and have not heard anything good about the 4 bbl conversion. Do your homework first!

I was just wondering if it was all good or bad feedback thanks i was just throwing around ideas thanks for your help though. saved me alot of time

Don't do it. Jeff1216 tried one so talk to him. He gave up and went to a Chevy Small Block and is now back to a straight 6. But if you do decide to go with the 4 bbl let me know, I have a Arizona Z car intake manifold and I'll give you a helluva deal on it. I will be going to sea tomorrow for two months... if you want it and need it before then email me to work out a deal and my wife can ship it to you. Ont he other hand I hear the Z Therapy carbs are outstanding.

My '73 240z came with an Edlebrock 4 barrel on the L28. I have had no trouble with it at all. I get about 23mpg, very good performance, and the set up is very easy to tune and maintain. I also have a set of round top SUs in the garage that I'm probably going to eventually replace the 4 barrel with. They not only are more correct, but I really like playing with multiple carbs. Bottom line - the 4 barrels work but the SUs are nicer. My 2 cents.

I proabely wont get the adapter but if i get the jim cook supercharger i still am gona need a 4 barrel carb any good recomendations that are beter than the holley it comes with? "yay more money to spend" :disappoin

No you don't. There are other options for the L6 engine which are probably still better than the 4bbl. You can get a set of performance SUs from ZT or Rabello Racing or go with a set of tripples (Webber and Mikuni are the two tripple set ups that jump right to mind).

Doesn't the Jim Cook setup come with Holley Pro-jection? That would be easier to tune than a 4 barrel and a lot better than a pressurized SU or Mikuni setup IMO.

Is this a supercharger for 1st gen Z's? I read discussions here where someone had come up with a SC for the Z but it was never put in the car and actually proven. (I'm trying to convince my husband to supercharge the 77 if a proven product is available)

Just Say No! ... to forced induction.

I have heard that the Arizona Z manifold is the only one that works well, and a very knowledgeable Z club member has had one on his car for quite a while and tears a lot of other near equivalently modified cars up.

You may want to search HybridZ for info on this - I think that's where I saw it.
