Hey man, yeah i htought maybe rich and retard? but even on stock boost :S

I have a SAFC NEO comming but now think i should have spent the extra on a PFC>

I have a mate who offered to let me try his PFC to see if that sorts anyhting out, ill let u know how i go in a day or two after we have tried it.

The hesitation in mine is really sever, overtaking commodores is impposibble and imbarassing.

Mine is very noticable.But opens up again after 5000RPM.Due to a defect i have a standard zorst on.But get my other one back tomorrow.Ill let you know if this does anything also.But yeh very interested in the ECU swap.Keep me posted.

CHEERS

perhaps someone could donate a pfc from a car with similar mods and a richish tune, see what happens. i wouldnt try it for too long though with the wrong ecu thats just asking for trouble. it need only be a 5 minute swap. If it works its your ecu, if not, its a sensor or boost problem.

really does sound like management, but management does some funny things with the wrong sensor readings so it may not be the ecu.

thats all i got guys sorry. Maybe MANWHORE can help nytsky out your both in syd

After i got my exhaust back today(fujitsubo 3inch) it felt alot better.But can still feel a little bit of hesitation between 3 and 5k.Alot smoother but still there.

Im in the process of getting an FC(i bloody hope) so ill get it on the dyno and find out for sure.

hi guys got it fixed yesterday

on the dyno made 128 rwhp

fixed-

replaced fuel pressure regulator

replaced airflow sensor ( the 3 i tried previously where dodgy)

for some reason timming is quiet advanced because hte car didnt want to do any hting on the standard base timing? dont know why?

After tune made 270.9 rwhp or 202 rwkw ! very happy!

The air fuel ratio is still very rich according to the tuner, Tuner says when my SAFC neo comes should be good for over 300 rwhp.

Total mods are-

-walbro fuel pump

-metal intake pipe.

-pod filter

-boost 10psi

-dump back exuast

-Delta fin fmic

-stock turbo and stock ecu

-oil catch can

Pretty happy with tune so far

Holy crap thats a huge increase.Where did you get it done?And how much?

How did he tune it exactly if you done have a SAFC or power FC to tune it with?

well she definatly is not a stock turbo, especialy on an R33. I have just managed to squize 200rwkw out of mine at 10psi with all the mods and SAFC II. that is at 10psi, i guess top would be about 210rwks if all goes well at 12 psi. what boost are you running.

You sure those figures are at the wheels. not at the crank?

He got such a increase beacue the car was running so fcked and had to fix the stuffed things.

For some reason timming is in an advanced position bacuse the car wouldnt do much wiht stock base timing, the air fuel ratio is still way rich. the power figures where at the wheels and as far as i can see its a stock turbo. Unless its had some sort of highflow job done to it??

I hear of other people wiht good nick r33 with similar mods cracking the 200rwkw mark???

Im running 10psi boost

Got it done at FIST performance at wacol. Onyl work shop open after new years who would take my car with such late notice- i was not expecting the excellent service they gave me.

He basically just fixed my problems, u cant tune much with a stock ecu except base timming and make sure its all running ok.

i dont thin you have a high flow, if you had a highflow running 10psi your stock ecu would shit itself and you would be back to 128 or worse. 200kw is about right, its not really a number that means anything after all, actual figure could be + or - 50 but who cares, whatever that figure really is, you just doubled it. the increase is the only figure you can take from a dyno other than air/fuel ratio.

congratulations on finding the problems and having a car in top shape

i hope mine does that one day

i got 204kw with my stock turbo and ecu on 11psi. any higher and it hit R&R. my mate has 1 with 175kw and mine feels heaps better. before mine had the cooler put on and only had a cat back exhaust and was running 9psi it was a dead match for another mates car that had full exhaust, cooler and 11psi. i know that my turbo is stock, but i just think that my engine is healthy, and we had made a few "modifications" to get more power out of it.

now i have a remapped ecu and am running 13-14psi (still on stock turbo). while trying to sort out an idle missfire issue i put the old ecu back in and went back to 11psi. it felt like a grandma car. it was so boring. so i stuck the remaped ecu back in and wound the boost back up and it went back to being a fun car. i'm going to be getting a safc some time just to trim up the AFRs to get even more power. the remapped ecu is leaner than the stock ecu, but is still down around 11.4 at WOT at high rpm.

      Wanted to buy R200 longnose LSD 3.9 ratio

      By Ben_D · Posted

      Hi all,  I am in the market for an R200 longnose diff out of a Z31 300ZX, or S12 RSX, DR30 skyline, or similar, in a 3.9 ratio.  Preferably a late model one with the M12 crownwheel bolts.  The only easy to find advert for one of these was my ad back in 2007 when I sold it on this forum.  I sold the diff as I had sold the car it goes to, but as it turns out, after 18 years I got the car back late last year, so now I'm looking for the diff !  If anyone knows where to find a longnose R200 LSD with the M12 crownwheel bolts, drop me a line at [email protected] - Bonus paid if soomeone comes up with the original diff (stranger things have happened !).  Cheers   Ben D

      Back for more after 18 years - and where are the longnose R200 LSDs?

      By Ben_D · Posted

      Hi everyone, I used to post here a bit from 2004-2013, when I owned various Nissans, in particular my S12 RSX gazelle, which was sold in 2007.  As luck would have it, after an 18 year hiatus, the car found its way back to me last year, and over the past 11 months I have had the pleasure of restoring it with my kids.  One thing that I am after in particular is a 3.9 ratio R200 LSD for it.  I actually sold the one out of the car here back in 2007 , and it would be incredible if I could track down who I sold it to, so I can see how they have progressed over the years (and to be honest, to see whether I can get the diff back !).  Anyways, hi all and let me know "where are the R200 Longnose diffs all at these days ?  Cheers Ben D

      G35 Control arm and Compression Rods into a V35 Skyline.

      By sonicii · Posted

      Arms will be the same as the G35 or 350Z, but as above, there was a change in the lower control arm where it connects to the ball joint.  That said, you can remove the ball joint cone from your old ball joints and fit them to the new ball joints.  To be honest, I didn't think the ball joints themselves were different. The main ball joint is a bit awkward to replace, you really need to remove the steering knuckle to press out the old one.  Some people have used tools to remove it in place, but it just seemed too hard to get to. If you are going to press out/in that ball joint, then you may as well just replace the bushings in the LCA and the compression rod.  You can buy the compression rod bushing from Nissan, but the LCA bushes, you will need to go aftermarket. Much cheaper than buying the whole arm.

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.

      Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)
