If you can't find people who think that the 240Z is the best Z car, you aren't looking hard enough. There alot of people who love the MKII and MKIII Supras. Go to Japan, and notice the most loved RX-7 is the FC3S not the FD. The most most loved GTR is the BNR32. **** there are people that would rather have a HR31 Skyline than an BNR34.
Firstly it is not a 'law' that Japanese cars must stay under 280HP. It is a gentelmans agrement between manufactuers. Which is broken all the time. Do you honostly think the GTR weighing in at 3400lbs can sprint a stock 0-60 in 4.9sec and run a 13.0 1/4 on 280HP? It makes more like 340HP stock. The Supra dyno between 320 and 330 RWHP stock, that means its making more like 340-360HP at the crank... As for breaking something every 60K... What are you talking about? I'd bet any Japanese turbo engine would outlast most if not all American made engines. The SR, RB, CA, FJ, VG all will last over 150K.
Mazda doesn't own the patent for the rotory engine. They own the rights to produce the rotory engine. Otherwise it would be called the Mazda rotory, and not the Wankel...Where do you get this information that a rotor motor only lasts 60K? An NA rotor motor will last forever. The main thing that kills a rotory engine apex seals is 'pinging', and overheating. The rotory will die if either happen. The pinging will only happen under boost conditions, and your turbos spike or fuel mixture leans out for whatever reason. Pinging is an uncontroled detonation of the fuel. The fuel is burned very violently and erratically. It is an explosion instead of a clean burn. The resulting shockwave from the 'ping' shatters the apexseal. Apex seals don't just give out at 60K. Alot of blown rotorys have blown side seals or coolant seals from overheating as well.
WOW pick every thing I had to say apart why dont you...
Now a reply:
I know A L O T of Z car enthuthests and none could care a cent for the 240Z.
Im not much of a Honda fan so Im sorry to miss quote the size of the engines but you still even proved me right w/ the D series motors up to 1.7 from 1.5 and 1.6 respectively.
And it IS a government regulation (at least at one time, Im not up to date daily on Japanese government affairs) that cars must keep within a 275hp limit.. Now it is well known that manufactures fib on HP figures.. They have for years and still do here and abroud (sp).
Mazda does/did own the patten on the Wenkel rotory engine. It is known as the Wenkel Rotory from its German designer Dr Wenkel (his first name escapes me at the moment) but the ex-chief engineer of Mazda (which is pronounced Ma-zu-da in Japan) was impressed w/ the rotory and praised Dr Wenkel and bought the rights (i.e. patten) to manufacture it.
Your comment about Jap turbo engines out lasting Americans is most definitely opinionated. Now is diesels excluded from this? Because GM gives a 300,000 warrenty on their HD fleet diesel drivetrain they feel so confiedent in them. In anycase, American cars that come with turbos you can count on like one hand.
Lastly, I am a certified technician. I know how an engine works and what causes preignition, or what you call pinging or knock. Any engine can last a long time... Ive seen Saturn 1.9L, which have to be the loosest engine in the world, last upwords of 325,000mi. I dont know about RB's but SR's are great engines but require emense maintainance, the oil tubes that run across the cames gum up very easily and wipe out the came shafts.
I know all this information because Ive worked for different manufactures and in the aftermarket for over 10 yrs now. Plus I read and absorb all the information I can, compare it and seperate fact from speculation.
And about a GT-R doing 13.0, what model are you refering to? Cuz Rex's R33 only went mid 14's when he got it here? Again keep in mind that in Japan they have no emissions and run 110 octane sulfer free gas.
