New Rb Parts With Results

[Piggaz]

Hey guys,

Some of you may know my car has undergone some pretty radical changes. A quick rundown of the previous setup was; GT Block, Tomei 2.8, 270 @ 10.25mm procams, Nismo AFM's, ARC Twin entry intercooler, HKS GT-RS Turbo's, HKS dumps, HKS frontpipes and a Kakimoto Full Mega N1 catback all controlled by the old faithful Power FC. That setup on E85 @ 25 PSI returned a result of 402 RWKW.

There was a few little issues with this setup. One was a fairly obvious exhaust restriction which was in the form of a 2.5 inch restrictor in the rear muffler of the catback. BAD. Another one (although there are an argument for and against with this) is the HKS split dumps. They have been replaced with Tomei Series 1's. The biggest issue was the timing jumping around above 6000 RPM like a clown on a pogo stick. I realise some workshops don't seem to have/log/know-about this issue, but we did and it got sorted. The problem here for those that may not understand, is that the timing signal to the ECU is not accurate and consistent and means the tuner can't be as aggressive or precise with the ignition maps throughout the rev range. This has a roll on effect that the car wont produce as much power reliably as it could/should. The emphasis here is on reliability over power as we all want reliable cars, which is the reason I have decided to do this thread.

Below are the logs of the timing on the standard Nissan CAS setup.

Below are the logs of the timing with the new external trigger setup.

The new setup consists of a Ross balancer and a 36 minus 2 teeth trigger wheel and pickup. This is the first FULLY completed kit to be put on a car. Ross is now selling this as a kit made for the RB26 as a bolt on part and works with a large number of ECU's (all the main ones are supported). The only thing you see on the car is a wheel behind the balancer and a pickup, but to the untrained eye you really won't notice it. The OEM CAS stays to help with starting. The car fires up first time, everytime. That's something that the Power FC couldn't match, especially if the car was cold in the middle of winter due to the E85.

The pickup and tooth wheel.

CAS is looking factory.

Changes to the car from the previous setup are; Modified Garrett -5's (exhaust housing's ported to gasket size and Racepace Motorsport modified actuator arms) , Link Plug in ECU with a 7 bar map sensor, Ethanol sensor (more on that later), Tomei Series 1 dump pipes, Nismo intercooler, Racepace twin 3 inch exhaust from dump pipes back, Ross trigger kit/Harmonic balancer. I even went back to a factory airbox after running the pods for the last 12 months. I also have a TechEdge Wideband kit that I asked Yavuz to link bank into the ECU. This enables the ECU to 'trim the mixtures' while on the freeway. A little bit of fuel economy in such a highly modified car is nice sometimes!

First thoughts going from the old to the new setup is RESPONSE! It's on all the time. In places where I would be in 2^nd gear hard up it, I can use 3^rd and half the throttle and it's going equally as quick. I can completely understand when "Gav" (a WA forum member with a very similar setup) said "I have a choice of 2 gear's in any corner on the track". There is also NO shuffle with these turbo's. I couldn't get away with going up any sort of incline without the GT RS's having a spaz attack. This would play havoc with the AFM's and would send my AFR's south of 10:1 (Wideband readout).

The ethanol sensor is pretty much a carbon copy of what Daniel in Victoria did to his car. Same sensor and ECU. After being on E85 for just on 12 months I got sick to death of carrying around a crazy amount of jerry cans to do an event (Thanks Steveo for being the E85 tanker for me ) Some of the Vic guys can attest to this at one of their own DECA's. 11 jerry cans were taken down from Sydney to do what really is a skidpan day and had to duck into Melbourne to grab another 5, just to make sure we got home. Stupid it was!

Below is an overlay of the RS setup and he -5 setup. Pink being -5 and Green being HKS GT RS's.

More tuning will be done on the E85 tune in the very near future as we ran out of time before the SAU Nationals. The dyno graphs above were all done with the EBC OFF. Boost peaks at 24 psi and trails off to 22.5 22 psi top end. I'd like to see how far these things can go. Yavuz think's 440 450 rwkw with a little more boost and some more timing but the actual testing will be done and exact results found out soon. Yavuz isn't one to do things by half measures.

NB: I have not been paid to say any of this. I thought I would share what is a fairy big transformation in my own car with some pretty neat and new parts. It's good to see that some companies are still out there flying the RB flag for us guys and developing innovating new parts for these engines.

A big thankyou to Unigroup (Yavuz, Tyson and Mark), Ross from Ross Tuffbond for the trigger kit, Steveo for putting up with my rubbish all the time, Norm and Amy, Brett and Jack! Cheers guys!

Great result mate!!!

One question: what was the reasoning from going ARC intercooler to NISMO??

Looking at upgrading mine

[Piggaz]

I wanted my airbox and BOV's back otherwise I would have kept it. I had the same core on order but in a singe entry, but ARC went under before it got made!

Seen this issue many times before wait until you add another 25mm of deck height and see how far the timing goes out about 6000rpm!!

They really need an interface that converts the signal from 36-2 to a 360 degree signal - that way the PFC guys can play too!

[SS8_Gohan]

Fantastic results!! Great to see another Flex-fuel Skyline getting around

Will definitely ask Trent about his thoughts on the trigger setup too... PM price?

Would have been interesting to see the results from JUST the -5 change, see what #'s you got and THEN change the exhaust to see the difference. Or just same setup, but diff exhaust. Wonder how my Midori exhaust stacks up against the Racepace one... might have to do a little back to back at Racepace one day.

Do you know what ramp rate those runs were done at?

Well done again, it's an absolute beast and with a little more time with Yavuz, i think you're going to see some SERIOUS numbers!

Nice to finally meet you at the Nats as well

It will work with a PFC. It's just an extra converter box.

Steveo had the same issue with his RB30. Even Terry had this issue with his Blue V Spec II and that was just the typical "300 kw bolt on RB26"

Well don't forget the dumps were changed also. It would have been nice to do a back to back, but It was such a rush to get down to the NATS as it was!

Ramp rates. I don't know but I can find out when I am out there next.

-5 FTW!

Great result dude, been loving the sms updates over the past months.

When does your other 'item' get fitted?

[nfi]

Nice work Paul thats an awesome result. I'd be stoked. Really interesting to see the crank trigger logging. I'm still not admitting to being happy with twins but thats a damn good result.

Now more driving less excuses

That's still over in Japan. Can't wait for that bad boy

good to see the data logging for the dodgy CAS signal compared to the new crank trigger setup

Yavuz often talked about the issues with the standard CAS and its good to see some proof of how much i can effect tuning.. not that i didnt beleive him cause he knows his Sh#t...

Just dropped my car off today and i also have one of these balancers goin on and beleive me they re NOT CHEAP!, will be well worth it in the end. Though i may have to change from a normal PFC to a Dejetro but as far as i know the balancer works for both..

.... ive always wondered why ive never heard of this issue before from other tuners?, good to see Yavuz is on the ball

Cheers for sharing Paul, good info mate

In the scheme of things they are actually quite well priced. For all the stuff you get and the fact that it's a solid fix for the issue, it's money well spent IMO

Pauls one was a normal PFC and it will work on that with the 360 degree signal (although now he's a Link of course). The signal AFAIK is the same for DJetro to Normal PFC, but the converter box is slightly different then the Link one last I spoke to Ross. Leave it with Yavuz, he'll sort it out

Also which one is yours? The black one? We were there today

[GTR_JOEY]

yea the black one that has a f@uk load of dust and shit on it lol... the blue 32 with the flared guards makes mine look like a dump haha

Did u manage to get a look at the turbo and manifold set up i have?... theres alot of work to be done because of how everything sits so i wont be seeing it for a while

i pretty much only bought it because yavuz recommended it so if he thinks its worth it then he has me convinced

Hows does the power delivery feel? smoother or cant really notice it?

Yeah good point. Mine (RB30) basically got too dodgy to tune at 6000rpm, so I fitted the Autronic trigger and that kind of worked, but not too well because of how it's mounted. This one from Ross is far superior and during development as Paul and I have different ECU's the topic came up really early about it needing to be able to be used on a range of ECU's so they made the converter box that takes the signal and puts it into a 360 signal for PFC. Any ECU can be supported, thats the beauty of dealing with a company where you can talk to the boss - ring him up and have a chat and he can send you the part (or make it) to suit

Did you guys try the Ross replacement CAS at all?

Mark has one on his 2530 due to the timing going all over the place, A proper crank trigger setup is always going to be better at big revs though

Ahh. That one with the BW turbo on it. Nice Yavuz would love you as it's a big single!

I had a look, the manifold is automotive porn!

Power delivery. Well its very hard to comment as I changed to a Link G4 plug in + 7 BAR MAP sensor at the same time. But the starting (cold and warm) shits all over the PFC, it idles smoother and alot more stable. That is even with ID 2000's (2225 cc worth of injector)

Did you read my opening post Zebra? That's what the WHOLE thread is about! There are two logs there; one from the factory CAS and one from surprise surprise.... the Ross trigger!

Yes I read that, was wondering if you had tried the Ross CAS, is a direct replacement one rather than the crank trigger setup

Edit - See here

[Piggaz]

MLR has the trigger setup although he may has the Ross CAS replacement cover. I can't remember.

EDIT: Thats just a cover. I could of had that also, but Yavuz and Ross retained the factory CAS in the "Final revision" to help with starting.

[zebra]

Ahhhhh that would make sense then!!!
