Block size difference 2.7T Audi vs 3.8 GTR R35 - Massive

**GURUMAN** · 03-20-2016 05:56 PM

Purely educational thx to Rombotis tuning

**Bordom** · 03-20-2016 06:12 PM

Wow. Look at all the meat between those cylinders

No wonder those r35's can handle so much power... Looks like it's mainly due to that 60 degree block.

**DieselElectric** · 03-20-2016 07:38 PM

So, you're stuffing that into a b5, right?

Stock girdle

How much power/torque you shooting for? You doing any major trans upgrades as well?

It needs it since it is aluminum!

This looks like some photog trickery, it appears the 2.7t block is considerably lower in this pic, and the GTR block is higher up, closer to the camera making it appear much larger. Sort of like when guys kill big game animals and stand in the back of the animal to make it appear much larger then it really is.

Obviously it's a bigger block, but I think this photo is slightly misleading.

1100 whp and around 800 ft/lbs

Trans is already upgraded, but will be again on the edge.

Il will be on the edge of what stock gear can take (torque)

Far from being the point, but i guess if you say so, but i had both in my hands and couldn't believe the difference...

what bugs me about the Audi 2.7 is the siamese rod journal which i think is very stupid, but worked. Its like nissan engineers didn't take a chance an did 2 complete separate journals...

Funny enough I bet you could get that engine to fit in the b5 bay NP.

it would fit easier than a LS1

Do you have a build thread for your GTR?

Ya man.

Classic Brazzers camera work.

probably had to make them separate for cylinder spacing, because aluminum block.

You have to understand that the GTR is a much more expensive car to begin with, and Nissan also over-built the engine on purpose, because GTR.

How will everything else hold up (driveshafts, axles, etc)?

**Drehmoment** · 03-21-2016 02:24 PM

What's your point ?

Put the GTR block next to a 6.2 Hellcat or V10 Viper block and it looks puny too

I think it was to just highlight how v6 engines have changed (or progressed if that's how you view it haha) over the last 15 years. Iron vs aluminum, narrower v for smoother idle and tighter packaging, taller deck, girdle vs caps, etc

**Austonwerner4** · 03-21-2016 04:42 PM

One of the GTR's at the shootout over the weekend was pushing 70psi. 196mph in the 1/4.

What audi did is pretty typical of a 90deg v6. Something similar to the 2.7 would be needed on a 60deg v8. People did do odd fire stuff though.

What nissan did is interesting. A 60deg v6 would normally be like the 2.7 crank, but without the offset rod journals.
That looks like it would make the crank both heavier and weaker compared to a typical setup. Maybe the different firing order tunes up some crank harmonics or something so it doesnt see as much stress?

I just want to know if the bank lady was there?
We sooo need another bank lady thread, best thread ever!!!

**Yuppie** · 03-21-2016 06:09 PM

GTRs were running solid numbers at TX2K event. Stock I believe ran 11.6 bunch of them in the 9s and few in the 8s. However this was only if their trans didn't go into limp mode. and all we saw were converted to RWD.

I actually worked on a viper v10 and it was surprisingly small. The engine was also one of the easiest I've ever wrenched on. 6 tools and I removed the engine and tore it apart haha.

**Number54** · 03-22-2016 05:12 AM

Interesting photo and perspective. Keep it coming, these forums are boring lately...

Electronic center diff. Still awd

**CELison** · 03-22-2016 08:54 AM

They do rwd for burnouts then do a pass with awd

**getslideways** · 03-22-2016 09:02 AM

Performance benefits asides, do you miss a true manual transmission? (not necessarily an 01E, but just having control over that 3rd pedal?)

I keep debating if I could go DSG, and I just love rev matching and such as it keeps me entertained while driving normally lol

Its since been blackhole'd unfortunately:

It was pretty awesome, hopefully someone took some screencaps.

**christianb5s4** · 03-22-2016 09:33 AM

Apparently the bank lady thread is long gone, however I found an overview on another forum:

1) Guy finds out a hot girl at the bank owns a modded S4

2) Posts about the girl + s4 on Audizine

3) Thread explodes with leg humping, picture posting, epic comments, etc

4) The girl is actually on the forums

5) Hilarity ensues

You're telling me a block from a car designed to defeat the 911 turbo and compete with super cars is bigger than a Audi 2.7?? I would have never guessed

. Seriously though it is cool to see the side by side.

I understand, but then again I spent so much in the B5's that this GTR is a bargain

Thread was purely educational on the differences, not that a 2.7 is crap and the VR38 better

Do you mean the split pins? Audi did that to reduce the second order vibrations without a balance shaft.
