Mich hat das Thema mal gejuckt was SX im Rennbetrieb angeht.
Über "Erfolge" findet man relativ viel, allerdings sind diese wohl im Vergleich mit den Anforderungen zum Sieg relativ niedrig gesteckt, daher hatte ich eher mal geschaut was man denn zur Motorisierung / Technik unter der Optik herausfinden kann.
Erstmal ein paar Bilder verschiedener Versionen (alles 240SX'):
Ein paar mehr Infos dazu gibts im als Quelle benutzten Speedhunters Artikel.
Dort steht jedoch so ziemlich garnichts was unter den Fahrzeugen versteckt war, also weitergeschaut:
Eine kurze Info was die Rennserien betraf: Wie genannt, sind wohl IMSA / GTU gefahren worden. Zu GTU:
They were not very competitive machines. GTU was the Porsche 911 class. They would race against 911's mostly and the FC RX7's that would break. They were part of the electromotive teams that eventually mid 90's got absorbed to become NISMO USA."
Hänge ans Ende noch was mehr zu dem Thema. Zur Technik:
In den ersten Jahren wurden scheinbar KA24E gefahren, wie auch auf den Bildern ersichtlich. Eine Info (ob wahr oder nicht sei mal dahin gestellt, 100% konnte ich keinen Beleg finden):
I think the GT3 guys used a 13000RPM SOHC KA back then. Heavily modified crankshaft and valve trains at uber high compression or something. If I recall correctly it made like 250ish hp, later they went with the VG30.
Außerdem - später wurde dann zum VG30 (3.0L V6) gewechselt:
They were "240SX's" in name. As that was the body work they were based on. Tube frame, solid rear axles and VG30 N/A engines. Maybe in the early years they ran KA24's but if so they'd be special classed.
If I recall correctly those GTU 240's used a detuned version of the 300ZX GTO V6 at the time.
Tube frame chassis with VG30 engines and S13 style body work.
Hier auch noch ein Video von 89', in dem auch der 240SX zu sehen ist, so z.B. bei 7:50, 8:05, 8:38 etc.
Interessanterweise fahren hier sogar Ferrari F40 auf der selben Strecke mit dem 240SX und 300ZX Z32:
Wie versprochen, noch etwas mehr zur Rennserie / dem "Erfolg":
While they may have been "champion" back in the day, many people just ran the 24 hours of daytona and the 12 hours of Sebring, then went to regional SCCA events. Few teams did the full IMSA circuit. If you wanted to be GTU or GTO champ, all you had to do was finish most of the races in 5th or 6th and due to attrition, you'd win. If their championship was in the 88-93, then it was kinda pay to play. Meaning IMSA was run by Charlie Slater and was short on factory backed cars, tired of Porsche winning everything and short on money so if Nissan would commit to bringing two factory backed cars to run the whole season then they could run whatever they wanted. There was very little "regulations" concerning what was legal. IE a 2.9L KA24 could be legal if it used a stockish looking block. Electromotive was king of doing this with VG30 motors. An electromotive VG30 was "stock" based on the fact that the V angle had not changed and the cylinders were in the same spot in relation to the crankshaft but that's about it. This was in design to allow them to be competitive with Porsche 962's. It would not surprise me if they allowed them to take their race VG30 block/heads and run it in a 240SX as NA. They did run some 300ZX TT cars as well in GTO which was the big boy HP class which is what we raced, they were competitive but the turbo systems were prone to trouble. Back in the day all those turbo cars ran something called a "Dial a boost" which was a simple way to go from qualifying trim to race trim or to get a simple extra 50hp to complete a pass.
Stimmt aber, ist ein Z32.
