Waits for half of SAU to slap him..... :whistling::whistling:

NAH ! Just put my order through now through paypal. Precision CEA Billet 5558 0.63/T3/V-band plus two silicon joiners $1045 usd delivered to SYD. Wooooott ! ! ! Done! Hurrah.. lol

Were you sweating a little bit as you clicked that button, Ron? :P Lol just jokes mate, looking forward to results, good stuff on finally committing!

I was sweating like a pussy when I clicked that button Hanaldo, and Jase, ur welcome for a ride when done mate, but I'm not a errm..extremely safe/cautious driver..ask err Jez. lol.

lol well making the car even faster is not a good way to become a better driver IMHO.

i generally advise people to thrash the life out of something underpowered to improve their skill. i dont have any advice for you with a 5558 powered NEO :P

All the ones i have done have made big power on 22psi. Havent needed to go bigger boost as of yet

Will be tuning sr20 with 5558 external this week or next. Just running motor in

How did you go with that 5558 on the SR20? Ball bearing or journal? Do you have any further information relevant for SR20? (thanks in advance!)

I just bought a top mount T3 external set-up with 44mm tial gate but minus turbo and am trying to work out what turbo to go for (who isn't :wacko: ).

Currently makes around 270rwk out of a T2 3071 internal gate on 23psi with E85 and Tomei 260 cams, standard bottom end for now (Unigroup dyno) so I obviously want more than that, actually a lot more than that - ie ability to push to 350rwk later on. Unfortunately, it still has to retain reasonable response for a track car (very irregular street car) which makes it a bit trickier.

So far have narrowed it down to;

  • 5558 journal or ball (55 exducer, 58 inducer)
  • 5858 journal or ball (58 exducer, 58 inducer)
  • TD06SL2-20G 8cm (3" inlet, 52.5 exducer, 54.1 inducer - think it might be too small as most results seem to be around the 250-295 mark)
  • TD06SL2-25G 10cm (4" inlet, 60.5 exducer, 54.1 inducer)

It seems the 5558 will make the numbers but on high boost (not good for standard bottom end) and the 5858 will make it easier but will sacrifice some response in doing so (not good for turns 2, 9 at EC and fish hook and last corner at Wakefield ;) ).

Currently leaning towards the 5858 ball bearing but not sure about the response it will give.

jump on NS.com and have a look at DRE20's car, he has a 5858 and the dyno plot makes it look fantastic. very nice and broad powerband. Do this if you really want that 350kw 'down the track' setup.

FYI the TD06SL2 20G is a smaller turbo than what you have now and the TD06SL2 25G (T67) is more of a 6cyl oriented item.

If you simply buy a T3 .63 external gate housing for your current turbo and retune your car will improve everywhere. You should crack closer to 300kw and response will also improve. This is what I recommend you do.

If you want to sell your 3071, please PM me.

Yeah I never thought of that! I just put a brand new rear housing on it a year or so ago. But I think I will sell it.

Yeah I'm on NS and have seen the build. Scale is in speed so hard to tell but the graph does look good. Its also a large bore engine with 90mm pistons.

There's also Joels 5558 BB. Hard to tell what its like with the graph he has put up though.

NYTSKY: Is that not what Hi-Octane were running on their R34 at WTAC?

I think it was a 65, could be wrong.

The 32 had a 6262 on it and was absolutely flying. One of the better sounding cars there too.

    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂
