builte Posted August 29, 2023 Report Share Posted August 29, 2023 I have a 1986 Nissan 720 kingcab 2wd automatic transmission is there a Weber kit that it compatible I looked into pierce manifold they only had a version for 1995 1/2 Quote Link to comment
datzenmike Posted August 29, 2023 Report Share Posted August 29, 2023 Do you have the 'Electro -Injection' throttle body EFI? It's on the Z24i. Has two wingnuts holding the air filter on? If yes the manifold isn't compatible with the Weber adapter. You would need an earlier '83 and up Z24 intake. Also a low pressure fuel pump of 3-4 PSI. The EFI one is more like 40. The distributor is also a CAS (crank angle sensor) I'm also not sure how the ignition will work without the sensors on the now removed throttle body will set the advance. Otherwise if you have a Z24 and not the Z24i the '85.5 intake probably will work. Quote Link to comment

builte Posted August 30, 2023 Author Report Share Posted August 30, 2023 So I need to get the 85.5 intake when I get the Weber? Quote Link to comment
datzenmike Posted August 30, 2023 Report Share Posted August 30, 2023 You should put your location in your profile. All California carburetors changed to the ECC or electronic feedback carburetor. These had a solenoid jet in the primary that vibrated open and closed at a rate set by a control box and monitored by an O2 sensor to keep the fuel mix near stiochiometric. A kind of crossover between carburetor and EFI. Federal got just a carburetor. After April '85 there was a fuel injection throttle body option. I have a Z24 with a regular carburetor and the base bolt pattern is not rectangular but trapezoid. The two studs near the secondary and wider apart than the two near the primary. The intake for this has strangely shaped holes for the secondary. They are not just round like earlier carburetors. Can you post a picture? of carburetor? Quote Link to comment
builte Posted August 30, 2023 Author Report Share Posted August 30, 2023 Yes I will give me one second Quote Link to comment
builte Posted August 30, 2023 Author Report Share Posted August 30, 2023 (edited) As far as I know this is just a z24 Edited August 30, 2023 by builte Quote Link to comment
datzenmike Posted August 30, 2023 Report Share Posted August 30, 2023 Z24i has the round 6 pin connector at the back. You said Weber doesn't have a kit for it. I think they do. 1 Quote Link to comment

datzenmike Posted August 30, 2023 Report Share Posted August 30, 2023 Yup. I said Z24i sorry that's wrong it's still just a carburetor and a Z24. That makes it a ECC electronic controlled carburetor or Feedback carb and also the O2 sensor in the exhaust. The Z24i was EFI throttle body on April '85 and the half year '86 models. I guess it was optional? everywhere but definitely all California models would have had it. 1 Quote Link to comment

Does this mean there isn't a compatible Weber for my truck I'm happy to know it's a simpler carb but I'd still like to convert if possible Quote Link to comment
NC85ST Posted August 30, 2023 Report Share Posted August 30, 2023 Yes, you can swap a Weber on it and no need to change intakes. Get one that says it’s compatible with an ‘85. 1 Quote Link to comment
builte Posted August 31, 2023 Author Report Share Posted August 31, 2023 Ok thank you this truck is one of the more confusing vehicles I've ever messed if when I paint I might do it in Frankenstein green because of all the different parts lol Quote Link to comment

Only by my experience, even in California, I've only seen it on 1986 4x4's with the EFI throttle body. Quote Link to comment
