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.

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.

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

    • Hey Murray, hope all is good. I took your advice and put the filler first then the putty. Seems like a much better result but i noticed there are still pinholes. I even had pin holes when i initially put the putty on the body filler. Do you think it has something to do with my spreader being f*cked? I attached some images. This is the intially body filler i sanded. No putty yet  Applying putty. Final result after using wax and grease remover can see the pin holes. I just noticed as i look at the putty application it looks wavy not sure if it's supposed to be like that or because of the spreader.
    • Hey all just wanting some advice. I’ve just compression tested my RB25det and these are the following results  Cyl 1 - 135psi Cyl 2 - 135psi Cyl 3 - 120psi Cyl 4 - 140psi Cyl 5 - 130psi Cyl 6 - 125psi   do these numbers seem ok.  Thanks in advance 
    • I must say - this is how I picture all R31s!
    • Rust repairs completed, doors back on! pretty much totally back together running now. All future repairs will be fiddly wiring getting everything back up to road condition.  hasn’t  taken that long considering the condition I got the sub. note my helpers keeping the back seat warm 😂
