Figured I should probably throw this up for interest sake. In terms of power mods this time around:

- High flowed turbo

- Impul ECU

-* Plenumn Spacer

-* HDi FMIC

-* 3" exhaust dump / cat removal

-* K&N Filter

The *'d items are 'new' compared to my old 173awkw, so not a huge difference in terms of 'top power' but the power delivery is completely different - much more power early on in the curve, on decent boost heaps earlier.

gotta be very happy with that not being tuned yet,

get hold of the actuator mod off scott!

Definitely coming along nicely, its great to see the results and be able to compare between mods - essentially @ 80kM/h I putting down ~20% more power by really only doing air filter, FMIC and Exhaust dump.

More/Consistent boost would be nice :thumbsup:

thats just it, the response of your turbo must be much better after opening especially the dump.

that actuator mod scotts doing gets you on boost earlier, and allows you to hold a better line!

or you get get a stronger actuator with a long rod, and bend/weld to fit!

1999 Stagea RS4S

HKS 2835ProS

Nismo 480cc injectors

Plazmaman FMIC (turnflow)

3" Straight through exhaust with mid muffler and massive rear can (very quiet car)

260 deg type B Poncams

Greddy Profec B

Nistune (car has run with auto base image for around 2 years finally figured out that it was supplied incorrectly and just re-imaged)

Tidy up tune with Jez to check what if any WOT mapping changes were needed after installing the manual image. It is anyones guess what Nistune is doing under the surface. Plus I wanted to work more on getting the car off the line. The Stagea bogs down quite easily unless you give it the beans off the line. Changes made to very low load fueling and VCT has sorted out these issues.

Thanks Bob. The car remains Ms. Wolv's shopping trolley so it is unlikely to see the dragstrip. She will be stoked with the improvement off the line. The car has always had a very quick midrange but this touch up tune managed to pull all the ends together. Jez tipped more fuel in from peak torque and it like it a lot. Each degree of timing was making big jumps in power. The neo's seem pretty sensitive to using fuel to cool the cylinders compared to my R33. No doubt E85 would be brilliant with this engine but it is impractical in Sydney at this point in time both for availability, cost of changing injectors, ECU, flex fuel sensor and fuel pump.

Changing to the manual image on Nistune sorted out some issues with throttle recovery and general smoothness which has been quite annoying for the last year or so.

just need to stabilize boost and clean up under the curve but should have a bit more in her b4 exhaust housing runs out. but heaps of fun already

hell yeah e85 would not see that power on 17 with pump. reckon I can can get about 350 with a bit more playing but the .63 should choke about then. also about limit of the g box

Just got my NISTune done:

NISTune%20dyno%20AFR.JPG

Series 2 C34 with a boost controller and a home-made dump pipe. Not an amazing result, but not too shabby either considering the almost total lack of mods. Around 120awkw @ 3000RPM is nice with the weight these things are lugging around. Torque curve goes up at 2500 and then flatlines to about 5800, so she's very pleasant to drive. 13 PSI @ 2500, flat line down to 11PSI at 6000.

Edited by joorsh

My M35 made

168kw @ 17 psi

Had to bring boost back as it was pinging due to crap fuel.

Settled for 155 on 95octane @11psi (What i get for being out in the middle of no where with a shit servo around)

Not hard to fix

It's got:

full 3" impul Exhaust

Scott dump

Calsonic front mount

Impul ecu

Stock turbo

    • I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must me missing something? 
    • BRUH, one of the biggest mistakes of my life..... and i've had plenty ;[)
    • @Murray_Calavera iam just considering options 🙂 of course it is very expensive so that why i ask here 🙂  @joshuaho96 I looked at that GCG hybrid(i remember looking at it few weeks before) So this is "that" hybrid where i send them my turbo and they upgrade the inside to Garrett stuff and then they send it back. It cost around 1200-1300 USD which is FAR cheaper than the HKS and it is what iam looking for(i just do not have experience like this...to send something off to "upgrade" ) @tylink720 that is like 150 USD turbo no? 😄 I dont think i have the "ease on my mind" with this kind of turbo. I just put over 7000k USD to "LINK" up my engine...dont want to blow it up with cheap turbo 😄     EDIT: https://www.cj-motor.com/gcg-turbo-charger-for-nissan-rb20det-rb25det-high?srsltid=AfmBOooVeOZ6CZ6r1AIv5m-KPaa6BvudIPJTY8LW78khkd-gQlsaCht9 I looked at this and it seems ok? It is that CGC hybrid and it costs around 1250 USD (with back shipping). Do any of you have experience with this hybrid on NEO turbo? I quickly look thru the forum/web and it seems very good.
    • Echo the awesome sentiment 👍 Definitely a car worth saving. Looking forward to seeing updates as well.
