Looking for more bang for buck here. Goal is 270rwkws w/stock internals rb25det and I'd imagine close to 20psi. With all the other obvious bolt ons taken care of- what will give me a better power curve for the money? An adjustable exhaust cam gear or drop in tomei poncams? Or better to just save money and spend elsewhere? I think I'd be happy with at least 10kws gained in the band, but more than that and I'd definitely buy one or the other depending on the answers I get. Cheers

Bigger turbo. For a small increase an adjustable exhaust cam gear may give you a little. Bolt-ons that are obvious to one person may not be to another. What have you actually done?

Hyper gear. Fmic. Z32 maf. Coil packs. 740cc Injectors. Apexi pfc. Full 3.5 exhuast. Ebc. Then a tune. Might be missing something else. That's the list, currently deployed so spending my downtime day dreaming and making a list of items for my r33. I guess my question should be this- let's say with those mods making 270rwkws what can I expect to see from an adjustable cam gear vs. Tomei poncams? 10kws here vs 15 there? Rough estimates will do, much appreciated

Run E85 is the best bang for buck.

Bigger cams will just bring the powerband towards the right hand side of your RPM graph.

I would say, get it all running 1st, then get Poncams if you're not happy.

270kW with stock cams is a walk a in the park.

I did 372kW with stock cams, 1.7bar of boost on a stock unopened motor for nearly 2 years with track abuse before it exploded lol

How big are the prizes in your race category?

Haha that's a good question. Dont intend to race the car atm. But in the distant future I may go up to 500+bhp and was wondering if it's worth a purchase then

      Haha thanks Lith,  So it's currently working quite well and the torque reduction is setup and working phenomenal. It also got a custom torque convertor from All Fast in WA. Stall speed somewhere around 5500rpm unlocked but still with the lockup. The car went back onto the dyno after a 3yr hiatus (even with the dbw, and other mods completed in this time) managed to make ~515kw at all 4 hubs. Sean setup the Torque reduction which now sounds awesome and working well. We setup adjustable torque controlled launch control aswell.  Man what a feature. Especially when drag racing on street tyres I Managed to get out to the drags late last year and tick a huge bucket list item off of running mine and the cars first 9. Car went a 9.98 @142 Still had the young fellas car seat in the back aswell.  This was on 255/40/17 Nankang AR-1.  Currently the Turbolamik is still completing it's own torque calcs and managing shift times from there. Unfortunately emtrons can export is still a little restrictive to export the ecu calculated torque just yet but I have recently been suggested a work around that I just haven't had a chance to trial yet.

      Yeah its bad eh. Ey! Watch your mouth. Yep, spot on. The rear's are always gone too though from brake checking. I had them perilously close to a tree that we had taken down. I think the tree peeps may have taken it. Either for a trophy, or accidentally.

      f**kin' yikes! That insulation is the shittest stuff I have ever seen. You need to do an insurance job on that f**ker, pronto. WRT to the washer cover, I would have said that there'd have to be some at a wrecker, then remembered that it's a BMW, and reasoned that every single wrecked one would have been tailgating and so the front end would be trashed.
