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

      Squeaking clutch/throw out bearing

      By patrickxdf12 · Posted

      Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
