Hi guys,

As many of you are already aware, we have been developing one of our R35 GTR's in Japan to compete in the street class of the Japanese Time Attack series.

This car has been a mammoth project, engineered and built with ATTKD in Japan, sporting a VR38 stroked to 4.1 Litres, with the HKS GT-800 Twin Turbo Kit and uprated driveline, and yesterday in practice it managed a 58.6 at the Rev Speed Tsukuba Lap Battle, setting a new record for the street radial class.

More details to come later, but we thought you would enjoy some updated pics of the car in its current form

that is very quick, congrats Steve. I am also interested in knowing what tyres that was on

Hi Mark,

We ran it on some brand new Hancook tyres we were testing out.

I just corrected the time I originally posted, the actual lap time was 59.3 which as I said we are delighted with! :)

Correct me if I am wrong but that is very little improvement for such huge changes to the car. I gather that the suspension is not yet setup? <BR><BR>Also, I am curious as to why increase the displacement when getting HP out of these things is hardly difficult at std displacement.

Fair question Adam.

The car is still under development and has only recently been finished so this was an early testing session, we have a long road ahead with suspension tuning, more tyre testing and a lot more.

HP wise the car is also not running at full power as yet, long way to go before that happens

We elected to build the car tough from the get go to ensure it was capable of making big power reliably - We are using the HKS GT-800 Turbo kit and opted to strap it to a built engine rather than stock.

There will be more to come, we certainly havent seen the cars full potential as yet

Watch this space!

that's because the stock GTR is so good out of the box

but also because tsukuba is a tight circuit - and imo the R35 has outgrown it

the JDM tuners like Amuse, Mines, MCR are in the 58-9s with their square tyre setups, exhaust + ecu mods, huge aero parts hanging off the front and rear

im sure you'd see a bigger margin by % on a power circuit like fuji with a big hp built motor (just as HKS have done with benchmarking their continual development car/s)

Hit the nail on the head!

Small tight circuit and early days yet :)

LOL, I retract my statement.

Yesterday your post stated it's done a 53.9. Hence I said THAT IS QUICK.

Today your post has been altered and says 59.3. Now I have to ask, What is the hold up? :P

French pastries made it fat! :)

Small update for you all, it turns out the time I originally received was incorrect and I have confirmed from ATTKD who were driving the car at Tsukuba that the car actually did a 58.6, narrowly knocking their own white R34 GTR off the top with the new record for the street radial class at this circuit.

We looking forward to bring you guys more updates soon.

Cheers,

Steve

A bit of a random question but do the japanese take offence to the word 'Jap' written on the side of the 35? I know that some consider it an offensive slur.

Hi Ryan,

No they don't, and we have been doing business in Japan for a very long time :)

That's more like it! Well done! :)

    • I've looked up the parts number (41011AL501). It's around $700 OEM. Usually our Infiniti G35 here in Canada have interchangeable parts with my Stagea but the parts number are not the same. I have looked around and it seems the JDM 2005 V35 Skyline (which is the same as our G35) has the same caliper but I cannot confirm. And I can't find a repair kit. The inner brake pads drags on the rotor, seems to be rusty piston. Thanks for the info by the way
    • This coupled with 6-9 speed autos with ridiculously short gearing is why these modern shitbox cars always seem so fast off the line. If it wasn't for those things, Raptors would not seem fast. The problem we have is there is a driveability gap between a more gentle take off and a wheelspinning sideways launch. The difference between ankle flex required to achieve one and ankle flex required to achieve the other is about 0.5°.
    • Yeah I think I'm also with the opposite here. It's 'hard to keep up with traffic' because in the real world I'm accelerating with 15% throttle and they are pinning it. It feels like I'm being an overt dickhead at anything above 15% throttle, so the car sounds like I'm being an overt dickhead to keep up with/get ahead of traffic when I'm really just trying to drive with traffic. There would be no issue 'keeping up with traffic' if we used the same level of throttle input/aggression to drive around. People really do just drive around with their foot nearly pinned in econoboxes.
    • To be fair it's the other way around. 300kw is boring in a modern Golf or BMW. They are so competent / well-engineered / devoid of emotion that you have to go stupid fast to feel anything. Whereas the <300kw RB still makes all the right noises and it feels good to drive. Can pull off at the lights with the turbo whooshing and the blow-off pssshing and feel like the coolest kid on the block. Just don't look to the side where you'll see the bored housewifes in their shitbox Yaris/Corolla/Camry that kept up because you didn't go fast at all
    • 300kW is so boring in a Skyline, you'll get spanked by someone's mum's Golf with Alibaba pipes, and an email tune.
