I ran last weekend at the Symmons Plains 60th annaverary meet. Unfortunately after a good run the engine decided to throw a rod.  I've got the engine out but havn't pulled the sump off yet, I suspect

So it’s been over a year since an update. The first event last year was the Poatina Mountain Race, it was pretty much a 7km hill climb with the option for a navigator. I put my girlfriend in the sil

The car got moved on the weekend to start the Targa prep.

I took it for a test run today to get reliability testing km into it. revalving of the rear shocks feels good, it should give much more confidence at speed on rough roads.

Hopefully we should get some testing time at Symmons this weekend

Well it's been a busy past couple of weeks.

I decided to bypass the heater core to eliminate the possibility of slip heater hoses, I followed some advice on setting up how the coolent lines run from a local bloke who races a RB25. We have since found out that the coolent flows differently between a 25 and a 20, cause I over heated the engine and poped a head gasket. Luckily the head was still within the factory tolerances, so I only needed to replace the head gasket.

We got a good test day in on Saterday with 70 or so laps of Baskerville, the car is consistently lapping about 0.7 secs quicker a lap then last year.

well it appears on a 25 you don't need to loop the rear outlet, into the front inlet, so I just blocked the rear outlet. I have now looped the rear outlet into the front inlet.

The car with the 25 I copied the idea from is a very successful circuit car, and has done heaps of race km with the rear outlet blocked

I've been pretty lazy since Targa. I had the car out to a club day at Symmons Plains a couple of weeks after Targa, and dropped my pb down to 59.8. Since then the car has been sitting. But it will be back out for a hillclimb at the end of October.

Some pics from Targa this year:

I think the big inlet ports would make i laggier down low, and I wouldn't be able to run VCT in targa. I did have a good look at it, but I don't think it would be worth it.

I had the car out again last weekend, and I took over 1 second of my PB at Symmons Plains

Footage of me playing with a GT3 RS, and setting my new PB:

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Boost cut after swap(RB25DET NEO) R34

      By Duncan · Posted

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
