Umm no. Idiot. Sorry Lucien :P

Roy - 1 bar though I have no boost controller or gauge so not entirely sure... Ben tells me that it is running 1 bar.

Nice thing is that now it has a big fat midrange, which I hoped and expected Tomei poncam gear to result in.

All mods are:

*Trust dumps / 3.5" exhaust

*Factory airbox with Nismo filter (love that stock look)

*SplitFire coils

*Adj cam wheels / cams

*PowerFC

*Oil cooler

Hi there Ronin....good to see the e-mail notification still works after a few months. Well this weekend I pulled the engine from my GTR to prep it for the new HKS GT-ss turboes and also to see why/where the power has gone. As per my last posts in this thread my GTR with almost identical mods to yours only made 207rwkw on a Dyno Dynamics dyno...weird.

The turboes were fine, only done 35000km since previous owner had them rebuilt with 360 thrusts. No obvious leaks around the manifolds either.

Anyway its sitting on the workshop floor at the mo' and will be stipped down tomorrow and we'll see what we find....keep you posted.

hey marcus, when you say stock turbos, is that rebuilt with steel wheels or are we talking 100,000 odd km old factory originals? I have a set of the Greddy Trust pipes on the way from out buddy Nengun, so I would be stoked to see anything like this power.... cheers!

I will let you all know when I get it all on the GTR

700cc injectors

apexi PFC

split dumps

trust cooler 100mm

HKS dragger exhaust

and steel wheel turbos

all on a 1600km fresh engine!

stripped the engine today and found ..........2 screws loose in the back of the oil pump ....surprise surprise!...Also a degree of blow by past the rings is evident so I guess they have gone soft...this could be costing be a small amount of power I guess....anyways its one of those just in time jobs I think. Could have been a blown engine if I had put those HKS GT-SS turboes on and just ran it like that.....

10-11psi of boost.

stock dumps, upgraded front pipe & exhaust.

Interesting, both cars appear to make the same sort of power (within dyno variance, and small difference between dumps).

How many kms has your car done, and have you had a comp test on it at all?

cheers :D

My engine has done 240,000kms or so. The timing and fuel is very conservative on the tune to look after the old motor.

I haven't done a compression test to check things out yet. I guess I am happy enough that the engine is starting every morning with the number of kms on it. :)

I have a feeling that the dumps are restricting it a little but, overall it's a very nice car to drive in. The power delivery is great and I also have a trust lightweight pulley kit and an electric fan replacing the pulley driven one to sharpen up the engine response a little.

Just curious... I want to put some cams on to increase the torque and mid range.

My Power Mods -

Power FC + HC

Full Exhaust (hi flo cat, split dump, very free flowing exhaust)

Stainless Turbo to AFM Pipe

Shielded Pod Filter

600x300x75 FMIC

12psi

HKS Exhaust cam gear set at 0 degrees

Stock Turbo, stock motor, stock everytyhing else.

Heres my dyno -

209rwkw.jpg

I want to get a set of tomei cams, but the problem is I know nothing about cams...at all.. I know they can make the car idle rough, but that isn't too much of a problem for me. I just want all that torque.

So... does anyone have any educated suggestions?

I also want to accomodate for a bigger turbine later on down the track...

      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)?
