I'm looking forward to seeing all these cars and seeing what numbers they run.

I finally got my FMIC installed today so hopefully I won't be completely embarrassed. I'm bloody annoyed though that my ebc hasn't arrived in the post yet so I can get everything tuned up properly. At least it will be interesting to see what just a bigger exhaust and FMIC combo will run over my previous run on the dyno when everything was stock - 105rwkw!! I think the dyno operator said something like "better not let this one get away from ya".

Fingers crossed it's not gonna be too hot - it seems it always is whenever there is a drag, drift or dyno event on!!

doglet, its not just about big power, its about seeing where your car is at, and at the same time, it will provide some valuable info for people looking at doing different mods cos we can all compare on the same dyno on the same day with different levels of mods.

Matt, yeah what T-man said:)

Yeah I know it's not all about big numbers but it'll be nice to see some higher numbers with the bigger amount of cash that has recently been spent! :( Hopefully it won't be like my ex- girlfriend where I ended up getting not much in return after all the money I spent! hehehehe

Looking forward to seeing some R32's with RB20DET's still under the bonnet ;) so I can see where I am heading.

I'll be there mate, nothing wrong with the old RB20's :( No doubting how effective the RB25/30 swap is though, considering it cost similar dollars to build a fresh RB20 or RB25/30, you'd be crazy not to think about doing the swap if your motor died!

Will be good to see some big power cars though, cant wait

Hey matt/steve : do u think shaun would mind if i just had a look at the setting on my cam gear. I have checked them and it seems to be 2-3 notches to the left looking front on.

What does this equate to?

Joel: Do u think the dodgy wastegate mod of urs would work on my car. Im having problems holding any more then 13psi over 5000rpm.

Yer it would work. It takes a bit of fiddling to get right.

When adjusting it, it might be worth pulling all the timing & pumping as much fuel as you can in to it so when you send boost over 15psi for a second it won't damage anything.

I did call it bodgy for a reason though. :(

heheh would i be able to do this. WHat toolz will i need, as i have a huge tool kit, i will just need to by the equipment.

By asjustin the wastgate, will this change to boost pressure, or just allow it to hold better.

Enrico,

I've got a pic of the wastegate when I pulled it off I'll edit it so you know what it should look like.

basically you just elongate the holes so you can pull the turbo away from the turbo (towards the front of the car).

It reduces the travel of the wastegate actuator so in turn the wastegate flap never fully opens hence boost will hold in the higher rev's.

      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.

      Boost cut after swap(RB25DET NEO) R34

      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

      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...
