Is The RB 26 DETT a very good Engine ??

[brendonm]

It was mentioned earlier that they should have put the VG30DETT into the Skyline. The only thing wrong with that is that the chassis rails are'nt wide enough to easily drop the VG30DETT block in. I have heard of people installing the RB26DETT into a Z, but not the other way around.

Awesome idea though I suppose even if it did fit, there would be the 2WD/4WD drivetrain issue, BUT it would be a cool project.

Note that some of those Japanese hard tuned GTR's have been bored out to like 2.8 litres. I have video from the last Osaka Auto Masse that has got a whole bunch of engine bay footage, and some of those beasts are tuned beyond recognition.

Wicked, simply wicked...

TheCamel has a 400hp+ at the wheels 300zx, only internal mod is a copper head gasket. A comparison to the RB25DET is much more sensible.

[TheCamel]

Ok I am not sure where everyone seems to be an expert on the RB or VG. As far as not having a 300ZX with performance numbers close to that of a Skyline I find you are sadly mistaken. Escort Tuning currently has the fastest street driven 300ZX in Japan with over 827hp to the rear wheels. My 300ZX has 390-412rwhp depending on the dyno and runs a easy 12.85 in the 1/4 mile.
Current modifications include:

AVC-R boost controller (1.2 kilo of boost)
HKS Cat back exhaust
RS*R down pipes/cat eliminators
HKS Power Flo air filter
and a ROM tune

Basic tuning

the standard 300zx TT is a heavy piece of shit with shit gear ratios!

its spins the wheels in first gear then really boggs down through second ,third and fourth!

give me a gtr anyday of the week!!

I really don't know a heap about the 300Z except I have seen quite a few with broken cranks sitting at Advanced imports. I know they are a nightmare to work on, it seems pulling 50% of the engine apart just to do anything makes it for a mechanical pile.

I know they go very well. I have been in a couple and have seen some throw some serious poke on a dyno, but if your comparing it to the GTR your silly, stupid, and thick. Maybe from a rolling start there is not much in a stock standard GTR vs a mildly tuned Z but tune them both and the GTR will have it for lunch. Kai you should know better than anyone else.

VG30DETT is not very good. I'm being nice here, too.

RB26DETT is king. Pull them both apart and it is easy to see why.

The design differences are like chalk and cheese.

In order to make reliable and respectable power from each, the RB26 will require far less modification, whereas the VG30 will require massive internal strengthening and bolstering.

Count all the high output VG30's in Japan and compare that number to high output RB26's. QED.

how come nobodies mentioned the nice MKIVTT? i don't know the engine code for the Supra TT...

[SpeedAddict]

The code for the Supra TT is 2JZ-GTE. Great motor, on our shop car with a T-78, and HKS ignition components, stock internals, ran a 10.6 @ 135. This is in a car with full interior, a/c, radio, everything. I've got some awesome in-car footage of the car going down the 1/4.
Oh, yeah. It's an automatic.
As far as the VG30, they are a b*tch to work on!
Doing any type of custom turbo work on the Z is a dreaded task.
Long live the RB26DETT!!!

Im no nissan owner(maybe a GTR in the near future)but i know that when you're comparing the RB and the VG...the RB is THE engine!

i wont say much but im a loyal in-line 6 fan...here's why..

http://www.fortunecity.com/silversto...3.htm#Inline-6

and i read an article in sport compact car saying that the VG30DETT's counter balancer's tend to let go(!)...and they have water passage problems as well...if im not mistaken(please correct me if im wrong here),the VG30DE has oil jets but the DETT doesnt!..weird eh..there's even some problem with the water passage in the block...try check out sport compact car magazine's old issues..you'll see what i mean..

Weak points?Id say...to buy performance parts for the RB26 engine,you really need lots of limbs to get those.

[gang$tarr]

You guys should compare the 2JZ-GTE to the RB26DETT

[kai]

Dude I was speaking from experience....a couple of years ago at a Lotus car club drag day I got toasted by a Z that was running 12.1....thats enuff proof for me....cant beat first hand experience. Now considering that Mark and Joe could only manage low 12's at the night drags on friday I think I can stand by what I said. I do agree however they are crap cars to work on.....hmm maybe there are a few broken z cranks at AI because there are 1000's of Z's in this country compared to a few GTR's btw I know of a few broken GTR's as well

Sure they go damn good when tuned.

Give me a RB26DETT anyday though.

And as for my 2L beating it. I run 14.0, any 300ZX TT I have ever seen at the drags dosn't come close.

I had a go in one from Japan. It had all the HKS gear, huge single turbo. After driving it, it just wasn't acting like a car with that much crap on it should be.. so we grabbed the HKS EVC/VPC/FCON/ etc off it.

I have also seen some monsters though.

In my opinion though the 300ZX is an ugly duckling..

You have to take into account of 4WD at the drags though!

gangstarr...i believe the 2JZGTE is the closest rival to the RB26DETT when it comes to all out power with stock bottom end(maybe better).....another rival is from germany....the M3 engine.
another engine that's starting to get attention is the little brother of the 2JZ ..the 1JZ...JMS australia extracted crazy hp levels with stock bottom end!....

Im not sure bout the RB25DET though...


How bout 4 cylinders?i believe these are the candidates:4G63,SR20DET,3S-GTE,H22A,EJ20T...
(candidates must be engine without MASSIVE block preparation..eg fitting iron sleeves/block guard to B16,18C engines)

my favorite is the 3S-GTE and SR20DET...id take the 3S-GTE since its an iron block(heavy but stronger just like the RBs)and i like the Bore and stroke configuration(86x86).


ur pick?

[meggala]

the Z32 should only have one type of motor as this smart japanese guy figured out.

i'm not familiar with all those codes, can you tell us which ones belong to which cars?
