ok i said id update when i had my crap sorted out so here goes. this doesnt have anything to do with ice performance really but if you read over the last page ish it will make sense why im putting it here

172rwkw

rb25, pfc, fmic, 0.85bar, stock pump, stock dump, 3" front, 3" hiflow cat, 3" exhaust

a/f was tuned good around 12ish and seemed to run really well, hardly any knock

clutch died some time after and began slipping from 3k to redline after pump change

180rwkw

rb25, pfc, fmic, 0.85bar, gtr33 pump, 3" split dump, 3" front, 3" hiflow cat, 3" exhaust and 1300kg heavy duty clutch.

after the clutch was done, power check before changing any settings (as in the 172rwkw tune) a/f was just under 10 before doing anything, so the pump pushed the a/f off the planet. this explains why i could smell octane at idle and normal operating cos it was so rich.

power check showed 150rwkw odd ish. go figure?? powerfc reset got to to 160rwkw ish but nice a/f curve just rich as. a/f lean out and some slight timing changes go to 180rwkw.

perfect a/f 12 and the thing hammers now. its 8rwkw difference but it feels so much more

zest and it hammers, havent ever seen it like this and the thing responds very well.

so all in all the dump change the way the car comes on power and top end but didnt appear to "show" on the dyno as easily as i thought it would have. either way the power is stacks better and comes on much better now, this was the first time i was able to run the new dump and 0.85 because since the dump my clutch has been fried.

i have a dyno printout the shows the base map and then the final tune so ill put a before and after so you can see, its basically a 30rwkw shift up across the entire rev range also my power doesnt appear to drop off anymore

what i also noticed i set my rsm to measure power output and on the freeway at 100km/h thew it into 4th gear and gave it some curry. max power measured was 311ps @ 5584 rpm. converted thats 231rwkw so go figure :cheers: geez did it fly in 4th gear on full song woooohoooooo

Paul - It's good to hear the car's running well, especially the new clutch... got used to it yet :rofl: there must be a slight difference in dyno's (who would have guessed?) as the 8 kw difference we got would hardly the significant gains your speaking of... Anyway, thanks for the Q45 diagram, and look forward to playing with the Pro software ... mmmmmm

did you tune it Sam at that dyno-mite shop we went to?

would explain the low readings :P

:rofl:

Spot on...

BTW: REAL TIME EMULATION FOR FACTORY ECU'S IS HERE AND WORKING! Map tracing and real time tuning from laptop to Nissan ecu.... mmmm

oops... sorry to hijack thread :P

Sam.

thought I may ad my details for interest sake...

tuned at ICE last week...

stock turbo

3.5inch zorst, stock dump

SAFC

EBC @ .7bar

FMIC

ARC airbox

Rebuilt bottom end with ARIAS forgies

256º cams

208rwkw

pretty darn flat curve too... the figure is probably a bit high but even if you take off 10rwkw to be conservative it is still making 200rwkw with stock turbo and ecu...

yeah the clutch is all good, just a bit jerky cos im still getting used to it.

ive worded my friend up on the powerfc cable so should have it within a week or so

hopefully it works and it can be used, have a feeling it might just work, soon find out.

h nick thats some nice power, the differences we have are cams, dump pipe and tiny bit more boost. seems u didnt get issues from runing larger cams with a stock turbo and normal boost, i just remember seeing bass junkys before and after with tomei cams and he lost power. did you have a before n after on the cams? id love to see how each of ours feel cos cams would be a nice upgrade for the next step

no sorry don't really have a reliable before and after dyno on the cams... they definately made a difference tho, it really likes to rev in the top end now and i got pretty much the same peak power as before the rebuild, just now its at almost .1bar less boost... after I put the cooler on I'm still recording the same peak boost on my ebc just with almost 40rwkw more peak power...

I think a power fc and split dump pipe would give me a better midrange but there are other areas of the car that need work first... I think if your happy with the power and the way the car drives, don't be too concerned with the dyno figure...

Just as an example I recorded 178rwkw before the rebuild on dyno 'a' and then 166rwkw after the rebuild on dyno 'b' with cams and a front pipe added... then added a FMIC and got 208rwkw on dyno 'c'

btw love that series 2 front end... wish I had of know more about R33's when I bought mine

Nigel has been tuning my car since November.Here are the results.

S15

fmic,exhaust,pfc,ebc .............. ...... 180rwkw

Greddy T518Z,afm,dump,inj,pump....200rwkw

Tomei step 1 cams............................235rwkw

HPI exhaust manifold .......................242rwkw

I am replacing the 80mm exhaust with a 94mm next week.

Car has standard bottom end,done 179,000km and runs 20psi boost everyday.

Nigel was the fifth and last tuner to work on my car,I cant say enough about this guy.

are all these figures from the same ice dyno?

cos thats a pretty good increase of 35kw from the cams :uh-huh:

Same dyno,3 months later.I snapped a rocker and thought it would be a good time to upgrade the cams as well as fit a Tomei rocker stopper kit.

The following upgrade to a HPI exhaust manifold,whilst giving me 7kw at the top end,actually gave me 17kw at 4100rpm.Shows the difference paying $1200 for a Jap one with a bit of research behind it over a no-name one on ebay

good stuff, but recently i've been hearing a few stories of snapped rockers on s15's got me worried..

as for the manifold - good to see not everyone buys chinese copies and thinks that their just as good! :cheers:

I had raised the rev limit to 7800rpm,back down to 7200rpm,and my car had done over 170,000km at the time,thats like 12 years driving in Japan,double power output,only failure,gotta love Nissan.

    • Yeah, thumbsup from me. The distant shot of the bay just looks same-same as before.
    • Dad had a court case drag out with them from 1998 to 2004. He was in a not at fault accident, NRMA were the ones who covered the other person. They tried to blame his neck injuries on the fact he'd had an injury in 1981 on his extreme lower back where he slipped a single disc right near the bottom. Had been all cleared from that injury for years. This accident destroyed his shoulder, and f**ked a heap of discs in his neck, and he still has major problems with it to this day. Sarah's sister while on her L plates had a small Suzuki Alto, she had stopped to give way to an ambulance, and someone changed lanes behind her because there lane was also slowing, and rear ended her at 80km/h. (She had been stopped for a few seconds already too!). Car was completely f**kED. NRMA sent the vehicle around to 3 different workshops as they kept claiming "We believe it can be repaired, and not written off, we just need to find the correct workshop". It took 3 months, and a lot of arguing before they'd concede and wrote it and paid out. About two years later her sister had a Lancer, someone pulled out of a stop sign without stopping (in an 80 zone). Her sister swerved, hit the front of the other persons car (Instead of dead t-boning the drivers door), which ramped her Lancer, and made it roll multiple times down the road. It hit every panel on the way through. Her sister had slid her self out of the car, and remembers the ambos walking to the accident (They'd been sitting at a set of lights just down the road and witnessed it) and they were saying "Well, this ones going to be a fatality, no way you can walk away from that". Well, she did. And then NRMA sent two assessors out to look at the car, both of which wrote it off. They tried to send another assessor out, except a HUGE uproar was raised, and they FINALLY paid it out. That was on a car, that had damage to EVERY panel, you could see from 100m away the whole car was also twisted, roof bowed etc. Nah, we'll try get out of needing to payout on a $10,000 car... Her sister ended up with major shoulder reconstructive surgery being required, and was permanently limited in her ability to do her job as a nurse after that, as she can't (And was told before surgery too this would be guaranteed to happen) regain full strength in that shoulder. However, there was no choice to not have it, as she could barely use her arm, which was her dominant one, and was in near constant major pain. (And she's the type of person that would try and walk off a broken leg!) NRMA did the biggest run around on the personal injury side too for about 18 months, even to the point of trying to put 100% blame of the accident on Sarah's sister, even though the other driver admitted she didn't look, and didn't stop, and was charged by the police. Sarah used to have a Barina insured with them. It was a policy setup, paid all 12 months in advance. At the end of the 12 months, Sarah was living with me, I reviewed the renewal, it clearly stated "If you do nothing, your policy will cease on XYZ date". We did nothing, as we moved her insurance in with all of mine and I was with Shannons. We find out 10 months later, NRMA decided, because he DAD had a car insurance policy at the same address as what Sarah's mailing address was (Garaged address had been changed), that they'd put Sarah's (What should have been non existent policy) onto her Dad's month to month charges on his credit card. We had to jump through hoops, to get a refund. They didn't care that we actually found the letter that said "If you do nothing, your policy will cease" they made us prove we had NON COMPULSORY insurance else where before they'd issue the refund, and after they agreed to the refund, it still took another 6 weeks and 3 more phone calls for them to actually process it. They also had two insurance claims from storm damage, and they were an absolute cluster to get resolved as well (one vehicle, one house). Some how, up until about 3 years ago, her parents were still loyal to NRMA too, and we were like "How the hell are you so loyal to staying with them, when other places are so much cheaper, and they've f**ked you over every time you've ever had to make a claim?"
    • I got the four AN10 fitting welded up to the cam covers and started up making the head to sump breather/drain lines. The front passenger side cover I used a 45 up top and a 90 at the bottom into the stock VCT head drain spot (3/4" BPST to AN10 adapter) thats unused on the RB25DET NEO with some speedflow flame shield to protect it from the manifolds heat.   back passenger side was a 90 up top with some flame shield and 45 at the sump end. The rear drivers is 45 at both ends   the front drivers fitting is capped off for now but ready to go if i want to try moving the breathers around. I was told by the fabricator to leave all the welds raw for now to make sure there are no pin hole leaks. A lot of cleaning up, re bundling looms and degreasing to go as well as final assembly on the cam cover baffles. The first real test will be 28th March at a Circuit event. added complexity and more spots for leaks but overall looks relatively neat imo
    • Yeah i think the dash needs to come out. To get the loom or maybe just climate control and radio cluster. My mirrors are done i think the motors don’t work so well after flood haha i need the ac fan, you said you wanted to keep it for your 31 and interior loom not including boot. The wiper motor. I’m not sure how good the window surrounds are on the exterior on the pintara.  I will message you to get your bank details shortly 
    • Just another barrier put up to stop cars being modified. When we're all driving Chinese sewing machines, you won't want to modify it anyway, and you'll likely already have slashed your wrists and be locked up in a padded room for your own protection.
