L24 Battles Six S20's. Guess who wins?

Recommended Posts

The winning L24 and engine compartment seems pretty basic from the outside.  A few items to note:

  • throttle linkage replaced by cable
  • dead-headed fuel piping architecture
  • oil cooler and fittings
  • deleted mechanical fuel pump
  • alternate PCV system with large white plastic catch can
  • deleted fan
  • non-stock damper pulley
  • remote oil pressure measurement sensor
  • fibreglass belly pan
  • hood latch delete (racing pin arrangement)
  • stock battery, alternator, distributor, radiator, coil, starter
  • very light coloured distributor cap. Plugs seem stock.
  • stock wiring harness
  • unknown hose from battery area to drain on left tower/wheel well. It seems to go behind battery then across the fire wall to the transmission tunnel area.
  • heater hose delete
  • shortened/modified fuel rail
  • stock-ish fuel filter
  • Stock hood prop, vent elbows, rad over-flow drain hose, v-reg cover
  • Washer fluid hoses in place along with stock wipers
  • brake booster not in shot. Master brake cylinder and clutch master cylinder seems to be stock
  • no camber mods to shock towers
  • engine lift bracket in place

Looking over the engine compartment pic above... In addition to the stuff you mentioned, here's a couple things that caught my eye:

Special "racing tape" secure on the clutch and master cylinder caps.
Multiple piece upper radiator hose? Hose clamps in the middle?
Vent nipple on valve cover angled forward to adapt to different PCV system.
"OIL" cap. I thought the early ones were elephant?
Couple unharnessed wires up and over the left strut tower. Is that stock?
"D" shaped washers on some of the fender bolts for clearance into sheet metal corner.

Blue,

There are a great number of mistakes in your posts on this topic. Have you simply transcribed all this from another site, and have you used machine translations for Japanese names?

Or is this 'All Your Own Work'...?

So much for diamond rings and oil paintings :Bazinga:

Predicition: Values of diamond rings and oil paintings will most likely not drop through the floor just because somebody delivered a message telling you what you already should have known.

Takahashi Kokoh (l) and Motoharu Kurosawa(r)

 

Christ, what a mess. That's Motoharu KUROSAWA on the left, and Kunimitsu TAKAHASHI on the right.

This thread is going to be a real car crash. There are just so many mistakes and misunderstandings. Some really golden WTF moments.

And Blue, what's the true purpose of this thread? You've titled it "L24 Battles Six S20s. Guess who wins?", but why? You seem to be framing it as a simplistic L24 vs S20 fight, but it wasn't actually anything as simplistic as that. What's your real agenda here?

The answer to the question posed by the thread title is, in fact, the latest Works car, with the 'ace' Works drivers behind the wheel...  . You might like to remind yourself that the car in question was still in fact a 432R, running all the 432R-specific homologated parts and having the benefit of all the factory team development carried out up to that point. The L24 being installed in that chassis was far (far!) from stock, with special Works-developed crank, rods, pistons, head and many other details, and was running at a displacement of over 2500cc (yes, 25% greater than the S20) allowed by the GTS-II class rules. You can hardly frame it as L24 = great, S20 = $^!#, can you?

Not only that, but I don't see any mention of one of the key points; The intra-company politics regarding the S20 engine and the fact that the very recently ex-Prince faction at Murayama regarded the S20 as 'their' engine and had effectively blocked the Nissan Works faction at Oppama from the better developments, updates and trick parts that the Murayama based team were using on their Skyline GT-R race cars. Murayama were not involved in racing the L6, so there was no potential for a reciprocal arrangement. Discussing the race career of the 432R without taking into account any of the Murayama/Oppama politics is to miss much of the point. 

And with regards specifically to the 1970 Fuji 1000kn race, you missed the elephant in the room for the whole event. Is that because you chose not to mention it, or because you didn't know about it? The big clue is what that particular event was supposed to be, and what cars were supposed to be taking part in it but for a recent tragedy. It had a huge impact on the race, and who/what won it.... It really ought to be taken into account.

There are so many driver names that require correction, I'd better list them up:

Family name in capitals:

*"Kitano Yuan" = Moto KITANO

*"Masahiro Hasayami" = Masahiro HASEMI

*"Kenji Tsubairi" = Kenji TOHIRA

*"Teranishi Teranishi" = Takatoshi TERANISHI

*"Takahashi Kokoh" = Takahashi KUNIMITSU

*"Saburo Koumuma" = "Saburo KOINUMA

*"Ishii Kazuo" = Kazuo ISHII

*"Sakurai Ichi" = Hajime SAKURAI
