datzenmike Posted January 10, 2021 Report Share Posted January 10, 2021 Did you get the adapter that comes with every Weber carb kit?? Has the engine or intake been swapped? Did this Did this have a carburetor on it before? and did it run? Maybe best to post a picture of your intake. 1 Quote Link to comment

No the adapter wont fit the intake but after sum digging i found out like ten mins ago that the person who sold it to me said it was a 1984 nissan 720 with a z24 but upon further digging its a 1984 nissan 720 with a z20 so i think i found my issue could i put a z24 intake on the z20? Cuz the junkyard only wants like $20 for a z24 intake and if not what is the right weber carb i need cuz i cant find one for the z20 1 Quote Link to comment
datzenmike Posted January 10, 2021 Report Share Posted January 10, 2021 That makes more sense. Yes the Z24 intake will fit the Z20. You may notice that the Z24 intake runners are square with rounded corners and the Z20 head has just round ports. It will still fit and work. Use a Z24 gasket. Z24 head top (upside down) Below is a Z20 head with the round ports. 1 Quote Link to comment

Charlie69 Posted January 10, 2021 Report Share Posted January 10, 2021 (edited) I have a Z20 that has the same manifold as a Z22. For the Weber to fit this manifold it takes a 2 piece adapter and also the short rectangular air cleaner. 2 Piece Z20 Z22 Adapter for the Weber 32/36 or 38 Air cleaner for the Z20 Z22 with the 2 piece adapter The Z24 manifold bolts up.

datzenmike Posted January 10, 2021 Report Share Posted January 10, 2021 I think the bolt pattern on the Z24 intake is wider apart on the two studs closest the valve cover side. I also believe the L series and the Z20 and Z22 all mount a similar size carburetor. When I tried to put a Z24 carburetor on an L series intake I had to oval two of the holes on it on the secondary side. The barrels are 34/38 on the Z24 carburetor. The same on an L20B is 30/34. The Z20 is 32/34mm. 1 Quote Link to comment
