Is 320kw for a unopened Rb25 Neo to much ?

Hey All,

 

So looking at possibly buying a R34 with some work done to it, there is one i have found that has had a fair bit of work done to it. it is pushing 320kw at the wheels.

is 320kw for a unopened neo to much ? it would be my daily drive, it wouldn't see any track days or anything as i don't live close enough to any.

It's probably about as far as you'd want to push one.  But as always, the length of the piece of string is in question.  Other factors to consider are.....1) how often has it actually MADE 320 rwkW in its life....ie, how hard has the previous owner driven/treated it?  320rwkW as a street car giving little hits 3 times a day only when warmed up is very different to the life of a drifter.  2) How hard are you going to treat it?  If just a streeter, then you might be just as happy turning the wick down a little bit and driving it around at 280-300 rwkW.

420kW would be a bit too much.

Don't let the Nissan out.

On 98

320 is nothing to a healthy Neo engine. Mine made 320kw on 98 for years.

320 is the number where everything on a skyline starts to die (if you go over it)

 

I.e

a) Too much lag
b) Gearboxes die
c) Clutches start becoming expensive/hard to drive
d) Grip is a problem, no tyres exist to keep your foot on the ground in RWD

As mentioned it's not "too much" as long as you confirm the rest of the setup being healthy, or whether it all looks sketchy as f**k. If it's a known car, decent human, people can confirm its status, seems to behave, pass tests, yeah it's not too much. Keep in mind though, and perhaps even keep some money aside for 'another' engine, because 'safe' does not mean 'safe indefinitely'. There have been reported failures on good setups well under 300KW as well.

Its one of those things, 300/320 whatever it is on a street car sounds bad.  But its not just the 300 you have to consider either, the boost to achieve it becomes an important factor.  The turbo being used also plays a big part.

In a street car where you are just driving and take off from the lights or overtake a B double etc you may not even see the full 20psi or reach the 300.  You might do it all inside 250 and say 14 psi and the turbo is a good one and easily handles it.

Then you have to look at how often you are going to do that.  In a year  - with normal sensible driving - you might do it 3 or 4 times and only for 5 minutes before you're backing off.  So you might use up to 300kw for 30 minutes in a year.

I always tell everyone that at 100km/h my car is a 2.5 litre twin cam straight 6......end of story - my turbo doesn't really boost before this in 5th.  If I exceed 100km/h or am going up a steep hill, then it becomes a turbo car with a potential 300kw that I may or may not need for a few minutes.

So yes, a Neo can handle +300kw, but its all about your environment, how you use it and your driving style.  I have 50,000 on my Gtst and have had no problems, but I did set up for it with a good turbo and supporting mods, so if mine can then the Neo certainly can.

Note that I am ignoring any form of showing off or street racing, you do that then whatever happens is ALL your fault.

You make a good point, how often am i going to use 320kw on a daily driver with just normal day to day driving.

You can easily put 300kW down without issue, if you know what you're doing to the geometry of the rear end and also pairing it up to decent mechanical LSD (none of this homo locked or shimmed business).

Putting 400kW down starts to get hard.

[tridentt150v]

Putting it down is one thing, keeping it year after year is another animal altogether!

[jay-rod]

Had ~320kw for about 2 years hard abuse
Now have ~380kw , with ARP studs.
Unopened Neo

Only thing i have broken is gearboxes over the years.

[Piggaz]

^what clutch are you running?

[jet_r31]

Id do headstuds. Id prefer a new headgasket aswell, then should live a long healthly life..

Cheers
