oldskoolvws Posted November 7, 2012 Report Share Posted November 7, 2012 Sorry, not in the market to buy but curious on whats the compression on a setup like that? Also, what do you do about the distributor? Me no smart on this setup. Link to comment
ggzilla Posted November 7, 2012 Report Share Posted November 7, 2012 It comes with the correct distributor, and cap too, judging by the photo. what do you do about the distributor? Link to comment
Laecaon Posted November 7, 2012 Report Share Posted November 7, 2012 It comes with the correct distributor, and cap too, judging by the photo. He is probably referring to running only 4 spark plugs instead of 8, when you attach a L-Series head... Link to comment
oldskoolvws Posted November 7, 2012 Report Share Posted November 7, 2012 ^^^yes this^^^ Link to comment
sssr20det510 Posted November 7, 2012 Author Report Share Posted November 7, 2012 You need to swap l20 timing cover and distributor and whatever l series oil pan and pick up your datsun requires. Compression depends onwhat head you use. The pistons have about 4cc of valve relief in them. With a closed chamber head it should be high compression Link to comment
oldskoolvws Posted November 8, 2012 Report Share Posted November 8, 2012 The pistons have about 4cc of valve relief in them. This answers my first question. You also answered the second. But how do the carbed 8 pluggers actually deal with ignition though? Now you make me wanna be in the market LOL. Link to comment
bonvo Posted November 8, 2012 Report Share Posted November 8, 2012 This answers my first question. You also answered the second. But how do the carbed 8 pluggers actually deal with ignition though? Now you make me wanna be in the market LOL. if your talking in stock trim? they have 2 coils and 2 pickups in the distributor they work just like any other distributor just with 2 plugs per cylinder on topic this is a nice set up Link to comment
sssr20det510 Posted November 9, 2012 Author Report Share Posted November 9, 2012 When you swap the l series head on you ditch the 8 wire setup and used l20 distributor. This is a long rod motor so it should rev like a l16 but have the displacement of a l20. This is not the same stroke as an l20b this motor uses longer rods so its more square so that makes it rev happy without putting stress on the bottom end. Link to comment

ggzilla Posted November 13, 2012 Report Share Posted November 13, 2012 Ah, it's a short block. No cylinder head. Guys, if you want to put the Z head back on, you can run the 8-plug distributor without a computer -- it's similar to a matchbox it will run standalone. Or use the 4-plug Z20 head. Z20 is a good engine for a 2-liter. Link to comment
datsunaholic Posted November 13, 2012 Report Share Posted November 13, 2012 So if it doesn't have the same stroke, what crank is in it? Z20E cranks have the exact same throw as a L20B and Z20S. L20B, Z20S, and Z20E all had identical displacement- 1952cc, with an identical 85mm bore and 86mm stroke. The rod length differences between a Z20E and Z20S (and L20B) was due to different piston pin heights, not crankpin throw differences. Link to comment
datzenmike Posted November 13, 2012 Report Share Posted November 13, 2012 What doug said. I have an '80 Z20E crank.... fully counterweighted and marked U60 same as the L20B crank... you can't tell them appart. Compression wit a stock Z20E head is 8.5 With an open chamber L head 8.9 Link to comment
