Stroke the N54 motor?

Sick335 · 01-04-2013, 09:59 PM

Has anyone done it? Any results? Anyone think about doing it?
It has crossed my mind...

Worth it?

Rotorocious · 01-04-2013, 10:28 PM

Why?

Easier and cheaper options out there

Ænema · 01-04-2013, 10:51 PM

There are a lot more cost effective means to making more power. BIG turbos are where the BIG power is going to be. The results from going from a 3.0L to 3.2L or 3.3L just isn't going to be worth the costs involved.

From the look of his mod list it looks like he's done almost everything out there....

RB turbos are impressive... but nothing close to what be considered a BIG turbo(s).

In fact, even the biggest turbo option available on the Vishnu/FFTEC isn't exactly impressive. Good powerband and daily driveability? sure. Monster power? no.

I think Dzenno has the most upgraded N54, and the only "internal" he's made any changes to is a custom port & polish to the cylinder head. Before we start stroking the engine, I feel like it makes a LOT more sense to to a "standard" internal components upgrade (lower compression, forged pistons & rods with ported cylinder heads) & a real TT upgrade (going beyond a stock frame turbo).

Bad idea, the R/S ratio sucks already.

Trojan4evr · 01-05-2013, 12:18 AM

VAC motorsports has upgraded internals. I would start from there.

Sick335 · 01-05-2013, 01:24 AM

Just a thought... What we really need to figure out is the AT transmission...

If you're seriously about big power and drags, you usually swap anyway. Just saying. I know most don't want to do that on a 2008+ luxury car, but it really is the simplest.

Or just go manual and know you are away half a second slower than you could be from a dig.

Vargas Stage 3s + port & polish + upgraded internals

Stroking a motor is usually good for adding torque to motors that are square, the N54 already has a long stroke and is a torque monster. Don't bother, as everyone said. Forged dished pistons, rods, etc is what is next. But your RB's are not getting you even close to what the stock motor can handle. Leave the motor as is unless you have big plans in the near future.

And by big plans he means his Stage 3 kit. Do it. You know you want to....

That's not what I meant. There are plenty of options coming to fruition. A production stage 3 kit is still a long way off. But a built motor is beyond the hybrid options out there right now.

Sick: no way. People will be making 1khp on stock displacement. (with upgraded internals, obviously

We stock N54 pistons and rods. CP, Arrow, Carrillo.

Mike,

Care to comment on the stock internals of our N54's?

I have heard numerous rumors on several different boards claiming that some model years of the N54 already come with forged internals.

For example a 08' N54 already has forged rods and crank but the pistons are cast.

Not trying to de-rail this thread but your post intrigued me to ask you.

Brian_VACsales · 01-06-2013, 04:43 PM

Hey Nick,

Check this thread for my comments: http://www.e90post.com/forums/showth...541474&page=10

Forged pistons or not, they are obviously stout!! More people will start pushing the limits and the stock units will fail. Even the 2JZ stock internals fail

Tony@vargasturbotech · 01-06-2013, 05:16 PM

Hey Mike, I tried calling you twice on Friday but got a verizon message. I am out of town on business til Tuesday morning, I will give you a call then.

joec500 · 01-06-2013, 05:25 PM

Do people feel that the N54 is a really good platform for monster HP? and when I saw Monster HP, I think of 800-1000 HP 2Jz's and some of the ridiculous EVO's.

I think once a proper fueling system is developed, we'll really find out. But currently N54 performance looks lie:

Stock - 270 WHP / 280 WTQ
Max Power Stock Turbos (No Meth) - 430 WHP / 450 WTQ
RB Turbos - 550 WHP / 625 WTQ
Vishnu/FFTEC Single - 620 WHP / 460 WTQ

And this is all on STOCK Internals with basic turbo swaps.

Honestly, just about any platform is capable monster power. It's just in how much money you're willing to spend. Whether it's a VW beetle or Honda civic or Toyota Supra...
