Hi there,

Here is a list of all the things that I have done to the car since I got it. I am really a beginner with this car....

HKS cat back exhaust, HKS fully adjustable suspension, cross drilled rotors all round, Apexi Power FC computer, heavy duty clutch with lightened brass button flywheel, Eboost 2. argo h beam rods, acl forged pistons, arp head studs, N1 oil pump, N1 water pump, gates racing timing belt, tomei 260 poncams, tomei adjustable cam gears, mls metal head gasket, 2 garrett 2860 turbos, tomei sump baffle

Who also would you recommend for a good tune? As far as I know the adjustable cams have'nt been adjusted also

Thanks

There's at least four different sizes of 2860s - do you know which ones you have? The larger ones will have more power potential but produce power at higher rpm. Have a look through the RB26 turbo upgrade dyno sticky in Forced Induction find sheets to compare to.

Not many people tune at 12.5 AFR when the boost is up - typically its more like 11.5 or 12, which will be safer for the motor. Maybe they're running less timing to try to compensate??

Did you ask Envy what happened at 185kms?

AFAIK Jim at Croydon racing and Yuvas at Unigroup are among the most respected tuners in Sydney.

The good news is i've seen worse

The bad news is i've seen plenty a lot better

But, without knowing which 2860's, how much boost and a myriad of other things... It's hard to say where yours sits exactly.

My guess, being only 320rwkw, its the smaller ones, in which case you have some issues.

I've never heard on "envy", are they well versed in RB performance? IF not, your money might well be better spent at a number of other places.

Thanks for the advice so far.....I am certain they are the dash 5's. If that makes any sense. The car was'nt actually tuned at Envy, they just had a Dyno Day which I took my car to.

Envy won't able to confirm what was happening at the end there on the spot, what suggestions would any of you guys have?

By the way I think the boosts are set at 15, 17.5 and 20 PSI

Thanks

    • Drilled the rubber out on a slow speed and it didn't catch much at all. Probably only half a dozen holes was enough to shred the rubber and it dropped off easily leaving the inner sleeve behind. Will tackle that later
    • I havent bought a manual cover for the dash yet and no cluster change, won't bother me too much, I just need to get that auto box gone, manual in! I miss my manual. 🤪. We started last weekend and managed to get the box out. Planning to start putting it in this weekend and then order a single piece tail. We were super careful to take time and not damage anything. It's my first time working under the car.  With my S15 mainly worked in the bay. This time, it was a headache because of three or four bolts only. They simply didnt want to leave thei homr and the one securing the tailshaft, another above the GB, and the one securing the lipstick was a shit. Mates mate, Davo caught fire 🤣, nearly opened his chest up with a grinder 🤦🏽‍♂️ and both mates nearly had a plate from the box land and slit their head open. Fun times. We all survived. Not the easiest working with limited access on jackstands. As I'm sure we can agree these are the memories which make us love our car. For all three of us, was an awesome weekend and Sunday 3.30am before tools down was a fantastic effort. I need to upload pics, but looks like it needs to be via Url now. We used to be able to just upload pics back in the day. It's been that long! 🤪 Im currently spraying rustoleum under body, not because it's rusted. It's super clean, but just so it's protected for the next 10 years. There was a few surface rust spots. Which pretty much wiped off with a 3M scourer.  Really impressed with how well the previous owner maintained it. Bank account went down so quick! Service, then GB - managed to get a spanking new 34 genuine box from Nissan. All the rest of the conversion parts from Kudos.  Went with a Nismo short shifter. New pedals and Exedy Clutch and FW. Ordered the Prp Rear Main Retainer kit which should arrive Friday and my first engine mod part just like I did with my S15 will be the Tomei Expreme Turbo Outlet. Already on order. It'll likely sleep next to me on a pillow during the coming months. 🥰 Last build was on my JET200GT profile and on SAU and Hardtuned I had documented the build. Planning to try to do that again. Brands feel scarce now. Wish we still had ARC and Apexi parts readily available. Exhaust - need some advice on this. I had an Apexi exhaust on the S15 and loved the tone. My mate had a HKS HP Silent on his 33 and suggested I go with that to avoid drone. I can't remember hearing an RB25DET running that so will likely need to wait for a meet or something to hear it.  Not after big power, just enjoy building it, and drivability with minimal negative attention.
    • Have a chat with Ben at Moore Performance or Jesse at JS Performance.
    • Thanks both. All good advice. Reminds me of drilling through stone wall for drainage pipe 😬 I'll let you know how I get on if I still have use of my hands afterwards 😅
    • Finally got shipping number for the intake and throttle body, shipped by UPS, so "should" be in my hands sometime next week, fingers fracking crossed
