OZ GTR35

Well Done Dan the Man & Jody, The OZGTR family passes on its best wishes and happiness.

Loz, Its best if you contact moto directly

The March one could still be on but please contact moto directly

Well, I spent some time at EC last Monday, I did a about 10 min at .7 bar setting, the apexi showed I only boosted to 0.71 Bar, Fu#k knows how but the car did drop in power and .7 was registered. I need to get a boost gauge and slowly pressurise the wastegate and watch when what PSI it opens. I will attempt to rig something up over the next week or so. This should identify the point of 1Bar actuators.

Does anyone know if there were any picks from the day? JHL perhaps?

Fatz, Good stuff, it was well timed I arrived just in time for 2 late wet sessions. Thanks for the spin.

Top day, weather was nice, no rain which was a pitty. The new tyres were good but did not improve my times at all. The best I could manage was a 1.53.

On my way home tonight I will set the apexi to .7 bar and I will check what the max boost was when I get home. This will hopefully close the .7 issue.

Maj, Yep just as usual. I will be bringing a few other drivers as well. Dave said it was a full day so we need to get there early. I can only hope to that its dry to about 1pm, then the sky's open up and I can have some fun in the wet! Yeah!

I bags not sleeping with fatz, I would struggle to keep my hands off that slab of man meat!

Red, It did not matter what timing /fuel/cam settings we used the car did not get any substantial increases. Cams in to the standard engine would help lots, but they don’t exist in my car so, tunning can only do so much.

Maj, I send Dave an email yesterday and told him the count was about 8 people, including a couple of 1/2 days. Thanks

Zane and I have our application and are ready to do our best.

After Duncan & Fatz drive in last years Dutton, both Zane and I have pre registered for this years. Our offical entry form has arrived. Both of us need to 2s licences. I know SDU can get them, what is the process? How long until SAU gets them? Who else has pre- registered and is going to drive?

Fatz, I may pop in latter in the day. See what the boss has planned.

Half day 9am -1pm about $120. Passangers in cars $20 for all day. $0 to stand in the pits and watch the cars go round and round etc.

Will be good to catch up and have a chat Mark, look forward to some good fun. I also have a NA Supra turning up on the day as well. 1/2 day only.

The next pan day is the 17th April. I will chat to Dave face to face Monday when Im at EC.

I have no doubt that the 2530 are a more suited turbo for a standard GTR then the GTRS's. I have bought the GTRS kit for the RB26DETT. The gaskets etc were for a 6 cylinder so Im sure it was not for the SR20. I spent some time on the web and I was unable to find any specs on the exhaust housing that was in English. I think the true test will be if Merlies GTSS do better then the 2530's. Pitty your graph was not KW/RPM, this would allow us to identify the lag difference in the dyno runs.

Sydney, The GTRS are suppose to have a 1Bar wastegate actuator so the solenoid would not have to work as hard. The .7 bar boost setting on a 1 Bar waste gate is another mystery I have yet to solve. Fuel BP ultimate no additives Timing was changed using the Apexi menu (IGN/INJ, I think) that globally adjusts timing and duty. The Apexi timing maps are basically aggressive so as we advanced the knock increased. Sydney Kid send me a PM with your number and I will call for a chat. I too would like to understand the issue if it is not "The GTRS are too big for a standard GTR"

Meggela, Back to old school posts, where you talk about performance, argue over the best parts for our cars and bitch about power outputs!

As per the tittle, Im looking to buy a GTR R34, but I cant find anyone to comply it. Any suggestion?

Syd, Leak down tests, all pistons spot on. Im using the APEXI boost kit, so Im not sure what the spring rate is. Steve, Changing the timing did not do much to the power curve, but it did develope knock at high RPM's so we did retard the car by a few Kw for safety but there was no huge gains when we started to play with the timing.

Steve, Turbine housing size is large, but I cant read Jap so the spec sheet does not help. See post 7 with a pic of the housing. Exhaust is a Jasma 3 1/2" with HKS dumps as per post 4. Emre, Yes I agree the result is no what I expected, I need cams and more air (3lt upgrade) to drive the turbo's, as I stated in the dyno results post. We played with the adj cams heaps. 0,0 / +2,0 / +4,0 / +6,0 / +4,-2 / +4,-6 / +6,-4 / 0,-4 / 0,-6 and the best result was +6,-6 but there was not a huge difference once you got up in the + 4 or -4.
