Hey guys and gals.......

i just bought my new r34 4 door its running a r33 series 2 engine and drivetrain and mechanical lsd

I have got a t04z with a .7 housing on it and reall just upgrade every thing from ignition microtect lt10 computer fuel pumps injectors and a list of other stuff the only internal is a better head gasket........

wat would be the next thing to do im pushing 310kw at the rears on 17.1psi on a cold night at the dyno on 98 octane fuel. boost comes on around about 4 grand some people hate the lag but i just love how angry it is to drive:)

i was thinking maybe cams any help would be great

thanks

t04z and only running 17psi??? they dont come into there efficacy rating to about 24psi and over you could make more power with better response with a smaller turbo.... lol.

Yes go some cams, front facing plenum, and FORGIES. You should be able to make a lot more just by winding the boost up more.

Is it school holidays yet???

lol settle guys, this guy is legit and is in my town.

Thats a bit strange though, only 310rwkw at 17psi on a TO4Z, which is capable of much more.

I run 314rwkw at 19psi, on a GT3076 - which makes almost the same curve as a 300rwkw NA V8 here, and plenty of torque (700nm at 3200rpm all the way to the limiter)

And why is there a R33 RB25 and drivetrain in there? There is nothing wrong with the Neo engine - The neo engines are actually better because they come equipped with GTR Rods, which are much bigger than the standard RB25 rods. So they are much stonger.

yeh you realise that by simply bolting all your stuff up to a rb26 that your still in the same boat you are now, if anything the older 26 will have a higher chance of failure.

or was 8500 for a built 26? doubt it.

just rebuild the 25 with quality parts and get a decent intake plennum on it.

    • Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that 
    • Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

    • What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.
    • While I was waiting for the new parts to come in for the charge pipe and radiator I decided to do some turbo modification. The drive pressure (exhaust backpressure) was a lot higher that I thought it should be. For 32lbs of boost drive was 55lbs. The turbine housing is a 1.10AR and my turbo builder has suggested to go to a 1.25AR. To test if a larger AR would do anything to reduce drive pressure AND not spend any money I decided to hog out the divider in my current housing. I removed it from the inlet and the whole way through the housing.  After reassembly and testing it doesn't look like this modification did anything for reducing drive pressure or requiring more fuel (making more power). Oh well, it was worth a shot. We'll get some data at the track if it makes it past the 60ft. I also machined a $7 shift knob off Amazon to fit my Stillway shifter since I didn't like the Stillway shift knob. Next on the list was the radiator replacement and fabrication of a new intercooler tube that had no silicon coupler. No pictures of this - I was short on time each night after work to get this done and didn't stop to take pictures.  Next was to get the clutch disks out and replaced. Previously when installing the dogbox I had ordered a set of the same sintered iron disks I had been running because I switched to the 26-spline input shaft. I thought it was odd that they didn't have any markings or brand name on them like all my old disks had but installed them anyway. At the track I could not get the clutch to lock up using my normal strategies. After two track nights I reached out to the clutch manufacturer and ask their thoughts. They said they had to switch the material out because they were having trouble getting the original material and that this new material would not take to being slipped very well.  So out with the first set of 26-spline disks and in with the correct material 26-spline disks. While I had the trans out I added an inspection/service hole. I've wanted one of these for a while. Now I can have a look at things and change the front cover shimming when needed (clutch wear). I hustled and got the clutch change done in a few hours on a Saturday. Hopped in the car and drove home. On the way home I did a 1-3 pull. When shifting from 2nd to 3rd the core plug in the back of the cylinder head popped out and dumped all the coolant. Thankfully I was only 30 seconds from home and coasted it there. Datalog showed nothing unusual and 2.5psi of coolant pressure. That plug has been in there since 1992 but I guess it worked its way out. Pulled the trans AGAIN and replaced the plug, JB welded it in, and made a brace. Also deleted the head drain I had added in during the bearing issue fiasco.  I am currently changing my boost control plumbing to make it cleaner. After that is done I'll make another attempt at getting past the 60.
