i think you've got a few qualitative errors there...

Naturally Aspirated Engine Comparison

______________ Disp. ____ Power _____ Torque _____ Size

Mazda RX-8
RENESIS _____ 1.3-Litre ___ 247hp ____ 159lb-ft ____ Small

Chevy 427ci
LS1 V-8 ______ 7.0-Litre ___ 550 hp ____ 530 lb-ft ____ Large

Porsche Carrera
GT V-10 ______ 5.7-Litre ___ 612 hp ____ 437 lb-ft ____ Extra Large

Ferrari Enzo
V-12 _________ 6.0-Litre ___ 660 hp ____ 485 lb-ft ____ Extra Extra Large


oh, and also it's "litre" not "liter" (as in "lighter")

guys where did u get thos infos? great find man!!

......... and I would really love to see the fuel economy numbers on that thing ...

They need to build that new Cadillac. It has the Maybach beat IMHO. We should start a poll... what would you rather have- new Maybach or the Caddy?

Hey, I think I will! Going to the top of the forum...

My favorite engine is the Ducati 998cc liquid cooled Testastretta 90 degree V-Twin.

Ohhhhh, that V-twin music! :D

2JZ-GTE gets my vote. 900rwhp on stock internals... yes, it has been done before and people are running over 700rwhp on stock internals with zero problems of blowing their engines. Besides, it sounds so awesome :D

...i don't wanna start a flame war over this, but everyone knows the RB26DETT owns the 2JZ... it's not Godzilla for nothing.

...not to mention, both those motors are HUGE... really really big. i think that Supercharger could easily make a very vaild comparison between a very tuned LS-1 with some nitrous or something (good ol' American way) and your Japanese TT's with the turbo 700hp... in the size and weight per horsepower, the V8 just might win out, and at 7.0L of displacement in such a small package could probably rival MOST of the power output of either of those engines... but when you get into the crazy tuning with 12k redlines and 2.5bar of boost, well... heh heh, iiiii dunno. it'd be interesting.

welcome to the forum Rookie... wait, should i say "club" now instead????

Rookie84

First, Thanx for the welcome

Errr... please explain why RB26DETT is superior to 2JZ-GTE?? I know RB has more R&D time(came out earlier than 2JZ) than 2JZ... but that doesn't make RB superior... I thought 2JZ had stronger internals?? Also there had been quite a few 2JZs capable of revving over 9k rpm in street trim.

If we're talking best in terms of longevity, then the honors had to go the 4ag series of 4-bangers from Toyota. Those motors are disgustingly bullet-proof. They may blow oil past the rings after 150,000k, but after that, they're good for another 150,000.

wakeech

hmmm... in stock trim, the RB smokes the 2JZ power wise (ya ya, they CLAIM 280 hp, then you put it on a dyno and it's like +400)...
also, i THINK (the numbers are SOOO old in my mind... i'll mail someone who knows, and they can gimme a list of reasons) the RB is slightly smaller, and lighter too... basically, the two motors are very close in terms of ability to make power at comparable levels of tune, but there are definite reasons (that i don't know, yet) why tuners one-sidedly prefer the Nissan over the Toyota.

JDM Supras are a bit slower than USDM Supras. They have smaller turbos. USDM Supras in stock trim are known to dyno at about 300-310rwhp which is higher than claimed 320hp at crank. JDM Skylines dyno at about the same as USDM Supras, thus they don't rape Supras in terms of stock performance. USDM Supras and JDM Skylines run about same in terms of ET, but Supras trap speeds are higher when compared to R33 (don't have data for R34 so I can't really say but I don't expect too much of difference given weight and power of R34). Yes, RB is lighter but 2JZ has more displacement which means faster spooling of turbos. So, following your reasoning, RB doesn't "own" 2JZ. Each has their ups and downs and it really comes down to what you are looking for.

Oh, BTW, comparing stock power level is not the way to compare the engines. Stock power depends on what kind of turbo(s) the manufacturer put on the cars, and also the tuning from manufacturers(a/f ratio, boost level, etc.). Imagine what it would be like if Supras came with T78 from factory? Then 2JZ owns RB? Yeah, I didn't think so.

Errr... give me a list of tuners who blindly prefers RB over 2JZ?? (Well, Top Secret maybe but I don't see any other tuners...) 2JZ is very capable engine. Look at JUN's Supra for example. It went 244 mph(give or take few miles... just pulled the number from top of my head) on salt flats. Nothing personal but you don't have anything to back up what you are saying... and as a lover of 2JZ-GTE, I don't like seeing people blindly prefer RB26DETT or thinks it's the **** simply because of the hype (from not being available in USDM market). Only advantage of RB over 2JZ I see is the ability to rev higher due to the shorter stroke. RB has more aftermarket support because it had been around longer and japanese people love high-revving engines.

yes yes okay, i don't mean to step on your toes: Supra's are cool.... i'm just sayin's all. the reason the turbos spool faster in stock trim is 'cause they're layed-out in a sequential format, as opposed to the parallel system on the RB, although the displacement would help too (ceteras paribus).
...one thing about boost on the Skyline though, is that you just remove the stock boost inhibitor, and presto, you're making sh*tloads more power. the 2JZ isn't much harder to do (modification just needs a boost something-er-other-thingy), but the RB's just that touch sweeter.

anyhoo, yeah, did some research, found out that the RB is smaller, lighter, and a way better revver (oversquare, and 2JZ is square) than the JZE which i believe are the primary reasons that it's preferred but tuners like VeilSide, Endless, Waste Sports, and Top Secret (to name a few)... actually, i think TopSecret took the Supra's chassis and tuned a 900kw RB26 and threw it in the front for some stupid video they made in the UK... :D
well, it's unfair to say "prefer" 'cause the AWD/RWD separation of the GT-R and Supra have them run in different classes, but whatever.

because of that rev factor, even though it does give up a lot of displacement, baring equalish turbos, you could probably get an RB to out power a 2JZ, but only at the top end.

...anyhoo, you're right that both has pro's and con's: i should have said earlier that i myself prefer the Nissan.

*edit: arguing one better than the other is like comparing a Ford small-block and a Chevy small block... they're really fairly competitve, with a few advantages and disadvantages, the biggest difference in popularity.
