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!

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

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
