My friend who bought my r33 gts-t took the car in for a tune yesterday @ ICE performance (had S-AFC 2, but I never got it tuned due to loss of licence) and got 185rwkw on stock boost!, they jacked the boost upto 0.75bar and got 205rwkw. AFR's seems good sitting on 12 or there abouts. Nigel thinks the stock turbo has been modified/hiflowed because the thing is pulling awesome power for what should be a 'stock turbo'. He recommended to get the turbo checked out to see what has been done it. A very pleasant surprise! I'll get my friend to post up the dyno graph. Current mods on the car are FMIC, 3" exhaust with hiflow cat (still stock dump), pod with CAI and a EVC 4. I think it's excellent power for the what the current mods are.

hang on that sounds a little odd. you said stock dump. if it was a modified turbo or what not then wouldn't it just choke more on the stock dump and make the graph a bit wonky in the top end when on full song. more air flow and the stocker dump sounds to me like it would choke more (in theory i guess?)

Nigel is pretty good if he can be bothered spending the time to do it properly.

When I had mine tuned, he stopped at a certain point, but I still wasn't happy with my A/F ratios. I asked him to keep going until it was flat.

but yes it does read high.

Before my tune, I saw about 168rwkw, and 200 after.

i think 160 and 190rwkw are more realistic in my case.

No it wasn't done in shootout mode unfortunately, it would've been great if my friend (pmgrz2) got a shootout mode. The power curve after 4.5k rpm shoots straight up. Nigel reckons things could get interesting if a powerfc + injectors was added into the equation.. and not to mention 1-1.1 bar of boost :cheers: (possible 230-240rwkw) Also the AFM is ****ed atm too so i'll get my friend to pop in a Z32 AFM while he's at it; nigel had to adjust the tune abit because of the stuffed AFM. But we'll wait and see when we get the turbo inspected when my mate finally has cash again. Damn now i really regret selling the car. :(

Paulr33: Yes still stock dump; and while my friend questioned about getting it changed nigel said it's probably not worth the money you spend with the gains you'll get. The top end is choking a little with it, as you can see the power curve drop off (when pmgrz2 posts the dyno); even when nigel leaned it out a little, so he then richened the top end abit again to make it safer. The AFR generally sits around 12. The midrange though is pretty good from my pov.

Also what's your opinions on the exhaust cam gear; I'm a firm believer of them as i've seen alot of awesome results with them on s1 gts-t's. the midrange gain is pretty good; even upto 20rwkw i've seen in some cases (in the midrange, not the end power figure). I reckon the car would drive alot happier on the street, but most tuners that my friend has taken the car too has recommended against due to not gaining much.

I'd also like to thank ICE performance on behalf of my friend for great service and tune. Absolutely top stuff and they'll definately be getting more business from my friend. Just out of curiosity, does ICE have a 4wd dyno?

yeah its a 4wd dyno. did he recommend change to a bigger dump pipe or split one?

i was disappointed at my tune and they didnt have much to say and sorta just said yeah its ok

oh well. ive got some crap to sort out (clutch + 3" split dump) and then im gonna try some of my own stuff and see what power i can get.

Awesome, I've just purchased a MY03 WRX so they'll be able to work on the car. ;)

My friend only enquired about a larger dump if i recall correctly, but from point of view i'd like to extract as much out of the current turbo as possible, so I'd put on a split dump (if i was my friend) and some exhaust cam gears for some more midrange oomph.

they told me cam gears do jack all and that dump change wont make much of a difference on the boost im running (0.80bar). im getting my split dump fitted on monday we'll find out hey. they said my power is down cos the boost im running

    • I'm seeing torque specs all over the place for the OUTER tie rod, but none for the INNER tie rod, where it connects to the steering rack. Even in videos, people are just tightening em up as much as they can with a wrench and that's it. Anything tightened down without torque makes me nervous. Anyone know what the spec is for it?
    • Hope you had a great time here in our tiny country.   The JDM scene we have here is quite small, it's mostly BMW, Volkswagen with burble tunes haha. But the few JDM cars we do have in the scene are pretty nice. Some of my friends drive cool s14's too. Both built engines, red one makes abt 500, blue one abt 400 i think?
    • Ye good idea , would have never thought of something like that. Might aswell do it to every pulley and the balancer while I’m there 
    • Use an LS1 or similar, via kit like Frenchy's. But.... It's probably not the alternator. It sounds like belt squeal, which would be because the pulleys are glazed. Rub every groove on the pulleys with 120 grit paper. Report back. Oh, and new belts afterwards too. The old new ones will be shitted up already.
    • Hello all I have 2 r34 sedans , one turbo one na, only recently aquired the na 34.  Man what is with these things.... My turbo 34 started sounding like a super charger, it was screaming at anything above 4000rpm , I took the alternator apart and replaced the front bearing which is the only one I think you can access and it did not fix the issue so presumably the bearing in the rear of the alternator is gone. ( diagnosed it was the alternator by taking off the aux belts one by one to figure out which pulley or bearing it was )  My friend gave me one he had lying around, Installed it , it did not squeal for maybe 500kms and now its started to squeal again briefly on startup  Recently got an na r34 and I replaced the timing belt, water pump + all the auxillirary belts. Runs amazing but it suddenly developed the same squeaking problem but significantly worse, Ive had my neighbour come down screaming at me because it was waking her up everytime I moved the car. It takes a good 2 minutes before it quietens down.  Im yet to diagnose where its coming from but im fairly sure its coming from the alternator aswell. My question isnt about how to fix it but rather where can you get a new alternator for an rb25 neo??? Ive searched everywhere but I havent been able to find a direct fit oem type replacement thats not genuine. All the automotive stores sell an oex one - BXA035 - which I picked up for cheap through a friend with staff discount , got it home only to find the connector is completelty different.... As far as im aware bxa035 is for rb20/30's and after a bit of figuring out the bxa035 has an ev14 type connector, which is tiny compared to the rb25 connector. I actually had an ev14 connector lying around which I was considering just replacing the bigger plug with to get the alternator working but the bxa035 is rated for 70amp vs the rb25 alternators are 90amp ( or so ive been told ? ) That paired along with the fact im about to install an amp + sub in the back and I have the stock sized small battery Im not sure itll do the job unless anyone has another opinion?  I know and have seen all the websites selling the ls1 alternator conversion kit but I am not going down that route, nor do I have the money to. Hopefully I can figure out how to get 2 brand new alternators for both cars. I would buy second hand which there seems to be many of but considering how common this seems to be im sure If I installed a second hand one it would start squealing in no time  Or even better if anyone knows how to fix the issue directly with the alternator itself... Any input appreciated Thank you     Link for bxa035 connector picture
