45 DCOE Setting for modified L28 3.0 engine


Recommended Posts

Hi together,

 

I'm new in this forum and hope to get some help regarding my Weber DCOE setting (Jet sizes, Tubes etc...).

 

I live in Germany and since four years I'm proud owner of a '74 Datsun 260z. I drove the car a few weekends and decided to restore and modify it a bit – which got even a bit more time after time.

 

One of the main modifications I’m doing is to swap the engine for a rebuilt L28.

This engine is soon ready for the engine dyno, but as I have no experience with the L6 I hope to get some help which carburetor jets (etc.) I should start with.

Actually the engine is at the dyno, so I can’t measure the DCOE parts that actually are installed - and I don’t get any details from Redline which carb-setup their kit has….

 

Here are some details about the engine I built:   (see added picture)

-          L28  F54 engine block with 89mm bore

-          L28 crankshaft weight-reduced, fine-balanced and temp-hardened

-          custom 89mm JE pistons

-          ARP H-shaft rods with L24-length

-          N42 head, ported, flow-optimized with 11.3:1 comp

-          44mm & 35mm valves

-          more aggr. camshaft

-          adjustable  pulley sprocket gear

-          Electromotive electr. Ignition

-          japanese stainless steel header and exhaust

-          Cannon manifold

-          3x Weber DCOE 45 (Redline Kit #K 659-45 4, Carb #19600.060)

-          open tubes / Ramair filters / K&N tube filters

 

There are a lot more details and modifications to it, but I hope these ones are the most necessary ones to know about.

 

Don’t hesitate to ask further – thanks in advance for you help!

 

Regards from Stuttgart,

Bastian

I guess you will have a "hot" cam. I would start with w50 and vf tubes from keith frank at yahoo dcoe group. W50 is for avacuum below 19hg. Otherwise it would be a hypojet26 alsi from keith.

Im running his jets and they are incredible better then weber jets.
