spanner? you need a 1/4" socket set.. spanner will hit the fan and/or the ancillaries belts I think.. never tried loosening the CAS bolts with a spanner, curious now if it fits lol.. always have used a socket

All done and didnt break the circlip. Im not a mechanics butthole but all went well and pretty straight forward. Ended up with 11-12lb boost heaps better to drive.

Next job is the new heater core i picked up. Not looking forward to that.

Then in 2 weeks going in for a tune. once i pick up the z32 ecu.

  • 1 month later...

Ok bit of progress and wondering where to go next. Got the ecu and nisstune and tuned and what a difference got 207 kw at the wheels which i thought was pretty good off a stock turbo, motor, injectors and fuel pump. Now what next to do. Im thinking afm, injectors and fuel pump. No idea on what type yet some research will have to happen

to be honest mate, you can't go much further without spending heaps and losing response anyway.

But if you want more power and I assume you do, next job would be new turbo. The stock turbo will die an early death if you push it any harder

supporting mods include but are not limited to:

-fuel pump Walbro GSS341/342 for petrol or F90000267 for E85

-Z32 AFM

-Injectors (if you want more than ~245rwkw on petrol or if you want E85 at all)

-coilpacks/clutch if need be.

Don't forget to run a direct battery feed for a new fuel pump regardless of which model you use.

Good luck

would i be able to reach 250kw with the stock turbo.

Absolutely not. Maybe on E85 you could get close, but it will be a bad thing to do. Turbo maxes out at less than this in terms of air flow, and when you push it that hard you are risking it flying to pieces (fragile ceramic turbine remember!!!!!!!!)

Cheers mate will probably go high flow turbo so boost comes on early unless there is an after market turbo that can do this and handle high teens off boost. Will get the fuel pump probably this week if i have time and then in a few months the rest and possible turbo

Look at http://www.sau.com.au/forums/topic/448435-factory-response-aftermarket-turbo-rb25/?view=findpost&p=7394103 to see what an HG highflow can do for you even with stock injectors. The ability to wind the boost up to values that will destroy the stocker is not to be scoffed at.

    • You are selling this? I have never bought something from marketplace...i dont know if i trust that enough. And the price is little bit "too" good...

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again?
