South Side Performance claims its kit delivers more power at lower boost pressure than a stock GT-R

America’s South Side Performance, based in Sioux Falls, South Dakota, has released for the first time a new tuning kit for the R35 Nissan GT-R supercar, which the company claims is capable of delivering 820hp (612kW) at the crankshaft. The new kit is based around a custom turbocharger upgrade that exhibits greater efficiency and faster spooling than the stock set-up. This efficiency means that owners will be able to run lower boost than the stock GT-R yet still achieve more power.

South Side Performance has chosen a pair of bolt-on Garrett ball bearing turbochargers for its kit. They require only one line to be changed and can be properly installed with basic tools and equipment.

The turbos were specifically designed to bring bigger power at lower boost and to utilize the fastest spooling compressors available for the size and application. The result is a turbo that makes more power at stock boost levels and starts making boost at lower RPM's than in the standard GT-R. The end result is more output lower in the power band.

The kit retails for $6,499 but requires owners to exchange their stock turbos. The price includes machining each of the stock turbos and installation of an upgraded actuator, 53.8mm turbine wheel, and 68mm high pressure billet aluminum compressor wheel which is efficient up to 32psi. The whole process takes about a week.

And the tranny will be good for one launch control if you're lucky.

1. Company claims 820hp at crank.
2. $6,500 gets you bigger turbos with no supporting changes (internals, TRANNY).
3. Saving grace would've been at least a PICTURE of the car, which isn't shown.

Fail.

This is awesome if it does what they say it does. That low end power promise might take away the need to use launch control...like it's needed anyways in the first place.

exactly what im thinking.

well this kit encourages those 60-200mph roll videos that's for sure.

is ne one sick of tranny jokes on every thread about gtr's no offence to the people that made the joke its just, i get it gtr + launch control + no warranty = funny. its rather annoying but ne ways. the kit is onli selling a turbo and some piping pretti much for 6g's i'm sure thats rather expensive no? can the stock cooling handle it? intercoolers and such? waht bout ems and or piggy back cpu of some sort? not enough info i think.

dam, 820hp...at least it will be better than the original...hopefullly

820hp at the crank, 0hp at the wheel.

The tranny can handle the power fine assuming you don't launch the car. Besides, there are already upgrades for the transmission on the GTR to harness the upgraded power.

nice, 0-60 in .... oh wait tranny broke at 30

You mean like the countless fanboys who appeared in every single thread in pretty much every forum there is when a 911, Z06 or ZR1 was the topic just so they could say "GTR is fastar, yo"?

lolololol :haha:

wonder how long till they report the tranny blow up lol:p

No, what I'm sick of is the people who keep posting these shops that "apparently" have built these "crazy" cars that have zero fundamentals. If the car is known for tranny issues, wouldn't you think that the first thing for the company to do is to do some sort of tranny upgrade to signal to the public that they're trying to make a car that's not going to be completely useless?

Care to tell us who has these upgrades and what exactly they do to the tranny to make it stronger?

Funny how Nissan can't make the tranny stronger, but some small aftermarket company can? :rolleyes:

I'm curious to see how this goes. Haltech (read: serious tuning house) managed to have one come apart during testing at about 650hp:

wow u so funny, like really really funny.



Holly shit ppl, the tranny doesnt just break in 2 launches jesus fucking christ. getting childish and fucking silly here

besides the tranny should be more durable as long as if u dont use the launch control 24/7


:rolleyes:

^ No, Nissan just voids your warranty after those 2 launches.

After looking at the V-Spec version, it just might be saving grace that a picture wasn't provided for this one.

Hope the people buying this kit has an alternative car for when this breaks down the moment it leaves the tuner shop.

The upgrade is for the gears, the important one is first gear since that's the one you launch with.

"Australian gearbox gurus Pfitzner Performance Gearboxes (PPG) have completed their first Nissan GT-R GR6 gearbox upgrades in the form of a drop in first gear replacement. You can see it pictured about sitting next to a standard GR6 first gear.

You can tell just by looking at this picture the basics of this upgrade, a much wider gear to increase strength. The main cause of gearbox failures occurs on the teeth of the first gears after extreme stress. Initially fractures develop and eventually teeth give way. Once one tooth is gone the rest follow like dominoes.

To follow on from this, PPG plan some gear upgrades for big horsepower cars as well as a 1st through 4th gear upgrade set. "

moar poowaaarrrrrrr

they should use straight cut gears instead of helical

so they modify the turbos..... great. what else is done to get that kind of HP upgrade?

Stupid thread
