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! :)

      Hello, sorry for being late to join the discussion, but my clock just died on me.   Ive tried to look at Michaels digital clock repair.docx and it doesnt work maybe the file has expired.   Please let me know if you can re upload it or take some youtube videos to show us how to get the clock installed? thanks

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
