Base or standard Weber 45 specification for a 240z

[jitenshakun]

For sure and if you decide to go another way I'm always interested in a set of 45s.

Again I want to thank all of you contributing to my Weber education and hopefully I will pass. Here are the specs I have gathered so far:

Main jets 

F16 Emulsion tube 

145 jet

160 air jet

 

Idle jet

60F8

 

Pump jet

45

As indicated these came off a running car and were synchronized on it and I have not altered that. The car had significantly more HP than the stock 240Z they are on now. The 240Z has 6 into 2 headers with a twice pipe exhaust, 280ZX distributor and if it matters an electric fuel pump. 

Is anything else needed to look at...?

You're a bit rich on main for a L24 and may need to be in the 120-135 range. The 60F8 is too big. 50f8 is where you'll want to be. 

The 45 pump jet depends on the intake/exhaust (probably 0.55). If you find a bad bog on acceleration it'll mean you need to change you accel combo.

Just wanted to add

Aux Venturi  4.5

Needle valve 2.0 

Choke 36

[jitenshakun]

36 is going to feel a bit big. 2.4L is usually 32 tops, 34 for a 2.8L.

A 4.5 aux is fine. 3.5 is an option.
