GT-ss or GT2530?

[GT-R Glenn]

If you havnt got a pump yet, the 044 flows over 700 hp
Also works intank.

It takes less than half a second, and is extraordinarily easy to do if you just practice a little bit.

I was chatting to another member of this forum once who said he was driving across Europe in his GTR with N1s being followed by a friend with 2530s.

The N1 driver stayed in top gear and just used the throttle to accelerate when required.

The 2530 driver kept having to change down just to keep up. I'd imagine that'd get very tedious after a while.

That's why I care about boost threshold. And it's also why I'm not alone.

That is what I am getting at when I say normal driving, GT-SS are way better

They make a GTR more of a total car, more than just a race car. Sure they will lose to a 2530 set-up car above 6000rpms, but when driving how often are you in that threashhold? And they are not going to lose bad, speed limit is only 70mph

From a dead stop, with a police friendly launch (something that will not give you a ticket) a GT-SS will beat a 2530! This will be a 98% of your driving. So, if you care about that 2%, by all means get the 2530

When I need to be, I'm not shy about putting my car up there

In a sense, the 2530s shift the powerband upwards. As long as you get into and stay within that powerband, it's nothing different from a GT-SS setup - except that you are more powerful. So I'd amend that situation - on the street, anyone who knows how to drive and spool up his 2530s will beat a GT-SS car every time.

I just gave you a scenario that contradicts that

[TREG]

Lol.
Pleased everyone agrees now Gtss it is.

I believe that story for sure. I think if you would rather stay in one gear, you should buy an automatic luxury car. The point of a manual transmission sports car is to shift gears. It doesn't get tedious. It's part of the driving experience. I drive sports cars because I like to drive a car hard. I head out into the mountains with twists and turns and elevation changes and speeds between 30 and 100+mph. I like to shift. I like to rev-match. I like to heel-toe. I don't like to putter around in fifth gear on a windy road.

I plan modifications based on what I want the car to do when driving in THAT environment, not puttering around city streets in traffic.

If you want a car with plenty of low-end power that you don't have to shift to have fun with, you should buy a sporty luxobarge with automatic transmission and a V8.

You didn't. You bought a sports car with an engine with great potential. Don't handicap it. Put 2530's on it. Shift the f*cking gears.

I might want to drive like that sometimes but I don't want to have to drive like that all of the time.

Good, because otherwise you'd be calling me a liar. lol

I use my car f***ing hard. Take it on track every six weeks or so with regular trips to the 'Ring. I use the car for what it was intending for more than majority on here.

The car is tuned as a good compromise between road and track.

To suggest that I should get a lazy V8 just 'cos I don't like to change gear on the motorway or because somebody else - in a more powerful car - has to change down just to keep up is idiotic.

I want my car to be well rounded, not a car I have to rev the sh!t out every time I want some power.

Hello,

Last year i used a pair of GT-SS with tomei pons B on my bnr34. This year i changed for Tomei procams (270° 10.25 with no head modification) and hks 2530.

In my opinion the last setup is much better than before. I have full boost (1.40) at about 4500/4600 rpm (before with gt-ss were about 4200). The power and torque are amazing for a rb26 with standard internals. No problem in street use with the power comes from 4000 rpm (about 1 bar) to 8200 rpm. Really not a great difference with GT-SS at low rpm.

Now i have 62kgm of torque (under 5000 rpm) and i'm happy. ah, i can stay in top gear and just use the throttle to accelerate when required like my gt-ss (like wrote this is only my experience).

Regards

Carlo

Exactachuffingmundo!

[SamuraiSam]

And that's the second reply from someone who has driven both turbo setups (GT-SS vs GT2530) on a GT-R. Count is 0-and-2, favoring the 2530's.

Carlo, sounds like a sick setup. I think your cam selection is spot on, and I'll be going with the exact same cams.

[SkylineUSA]

His a R34, slight difference

VVT does help on the low end, more so than the R32/R33 RB26s.

It (along with a set of 720cc's) works great at 414whp with a pair of GT2530's and a bone stock engine on the only GT-R I've ever tuned. No fuel issues whatsoever.

A Bosch 044 would flow more. It would also be more expensive, more difficult to setup, and noisier. It would also be overkill for your setup. If you are planning on further mods and going for alot more power, it very well may be worth considering.

Thats the thing, the 044 is cheaper than the Nismo/Tomei pump (its blatently the same model, same with their injectors )
I can get the 044 for about 140 quid and the other 2 for 200-210, so its just a matter of it being worth the hassle involved in fitting one

Car is only used for fun as I have a company car for commuting etc, but I'm planning to do a few trackdays in the next month or so. At the moment its laggy as fcuk (I'm getting 1 bar at about 4500rpm!!) but Rob at PT said it was running quite rich in the midrange with not enough ignition advance so once the injectors pump and cam gears are on a remap should sort it.
It almost feels like a big single the way the come in - floor it in 2nd from 3000 and it slowly gets past 4500 and takes off like a scalded cat!

Was enough to beat a Speed Six the other day though

I'm ideally looking for about 430-450hp at the wheels once its mapped with all the goodies fitted, and the sports cat removed

By the way, should they whistle a little bit as they spin up?
