Might wanna rethink that statement ...

The biggest (only?) advantage the 2JZ-GTE has over the RB26DETT is the extra displacement.

 

looks like the new 300z.....make it like the older models then it would look good

 

I saw that thread. motorex guy said that the rb had shorter rods! he acted like thats a good thing?! i think that guy is an idiot. you always want a longer rod. long rod=higher revs. i'm not sure if indeed the supra has longer rods or not. but that has little value to the stregnth. and i stand behind my statement. the rb isn't better then the supra engine. btw, best power i've heard of for a turbo six is a grand national. i've seen articles with cars with over 2000rwhp!

 

Yeah ... I bet those 2K RWHP cars have a lot of stock components

Once you start building a motor all bets are off ... but stock vs stock I'm inclined to say the RB is better.

That's not to say the 2JZ isn't a good engine. But 800HP stock ... reliably? I don't think so.

 

Why do you think the rb is better? is it the lack of a metal headgasket that the supra does have? (the rb has a carbon paper gasket). i do like the higher reving of the rb. 800hp reliably...believe it! there are just too many around to not believe! reliable for a car with that much power. if you ever build a motor with highporformance parts, the lifespan of the engine goes down. Nasport racecars have to rebuild their motors every few thousand miles. now these are extreme 13:1 compression motors. but the rule applies to most all pistons that are not cast. they will have greater heat expansion properties and will in turn have to be smaller then the bores and when cold cause piston-slap. not good on the cylinder walls, and hence the shorter lifespan then stock block by a wide margin.

now, 800hp reliably....to me this means it can last 30-50k miles.
thats what i would expect for a motor with that horsepower.
anything that last less then 10,000 miles, but more then 2,000 i would blame tuning. lots of variables....but i think any of us would probably take either one of these engines!

inline sixs have a better exhaust pulse for turbo applications

 

Well considering several of the Skylines that MotorRex have worked on have gone 500+ HP on the stock gasket I'd say that's pretty much a moot point.Too many around? You honestly think there are THAT many 800+ HP Supras? Sure there's more big HP Supras than Skylines but there's only ~60 Skylines in the US anyway so that's not really a fair comparison. Sure they might last some miles with that HP ... but can they last any amount of time with hard driving? I think not. Most of the big Supras seem to be dyno queens. And the ones that aren't are mainly 1/4 ET racers. Which is fine ... but does little to prove the reliability of an engine.Now that's just silly. Using high performance parts in a build doesn't decrease life span any ... how the car is used will. You're confusing installing parts with actually using them. If I install stronger components in a motor but drive it the same it will last longer than stock.

 

 

and in keeping to the topic of this thread, i think g35 looks nice! i hope the gtr version makes it here.

Wow, you named 2 cars. Big Shit! My point is that the stock gasket is a fairly good one. I wouldn't be caught dead without upgrading a head gasket on ANY car that I had plans with. Plus I don't give much weight to the reliability of an engines stock headgasket when determining how good the motor is ... if you want to do that that's fine. Knock some points off of the RB for not including a metal head gasket.Congratulations. You've named less than 1% of the Supras in the US. How this testifies to how reliable the 2JZ-GTE is ... I'm not really sure ...

Oh, how many of those spilled their guts on the strip?Really? Quote from Engine Builder Magazine:I don't see why everyone seems to think the 2JZ-GTE is a godly engine and can handle nearly 3X the stock HP on stock components. I wouldn't make the claim that the RB series could do that. I still think it's one of the best mass produced engines made ... along with Supra motor and a few others.

Back on topic, I don't like the G35 However, it does look better than the concept Skyline Nissan had at the Tokyo Motor Show.
