I don't agree with that at all. The reason Toyota doesn't really make anymore GE heads is because the FE heads & havetrains have surpassed them.
There was never much differances in what the better FE heads could do VS what the GE heads could do. The differance in performance came from your typical FE cam using .30-.32" lift with only 228-232* of duration on weak cam profiles.
Besides. Minus the 2.5L 4gr-fse. Every GR block v6 wipes the floor with any "GE" head minus the 2jzgte that's even been produced. All the "performance" engines being narrow angle at this point should say something. Even the last GE heads were not nearly as wide in valve angles as earlier heads.
Narrow angle heads overall have more benifits for less tradeoffs than wide angle heads.
AFA the 2gr-fse VS 2jz-gte. The 2gr-fse is very close in power/torque production. With all due respect to both, the 2gr-fse is likely the more responcive engine. it would be very interesting to see an old supra at a racetrack race with a stock 2jz-gte, then swap in a 2gr-fse.
My point was simply that why sell the supra now? They're selling so few IS350's right now already... (Hovering around
1,000 units a month.) A supra isn't going to go flying off the showroom floors to be profitable. Nor is Toyota a "Win on Sunday, sell on Monday" company. If it comes bakc, it's just to bring back a name. Not exactly something I can respect.
The 3uz-fe is an interesting engine choice for future versions. Tho one would greatly hope to see the 4.6L, or 5.0L v8 installed in its place as the 3uz-fe will be out of mass production by then.
situman citing the 350z as an example is not the best vision. The 350z is not some runaway success like the press would like people to believe. Nissan has
YET to sell 60,000 350z's in a single year
WORLDWIDE. Toyota sells nearly as many camry's in a single month in North America as Nissan sells 350z/fairlady's worldwide. Likewise, Toyota Motor Corp usa sells as many vehicles in one month as Nissan averages worldwide sales in a fiscal year.
darksparkz - I guess it would be fun to see an updated version just to see what Toyota would decide to do. In all seriousness, I do not think the i6's will last too much longer as a commonly found production car engine. They're more costly, slower in power delivery (more recipricating mass, more mass period) & do not offer any noteable advantage against other designs of today. There are too many people making superior v6 & v8 engines that are much smaller in packaging.
Sad, but true.
