The L20B hasn't been carbed for a while.  She is now running an '80 200sx efi system with necked down 280z manifold.  However, Joe my Datsun guru is almost done with my brand new intake manifold which is substantially larger and should offer much more performance than the small runners on the current manifold.

The current race motor:

(Subject to change with wild hair)

 

*L20B block, bored .020 over

*Z20 car (flat-top) pistons with Z20 rods

*L20B crankshaft

*U60 (U67 identical) open chamber head

*.030 clearance

*Ported and polished by me

*L7 Nismo rally cam regrind from Delta

*280z 6 cylinder manifold, cut down.

*200sx EFI system.  Weber 32/36 filter on AFM.

(De-laminated them and replaced old paper elements.)

*L16 exh. man, emissions casting ground

(See ratsun.net thread re: header on non-full race L motor.)

*'69 water pump, no clutch.
