I'm looking at buying some 256 tomei cams for my series 1 rb25det. I've found some for $909 delivered. Is this a good price? Anyone know of anywhere cheaper? Can u buy them over the counter anywhere in Adelaide?

On a second note my engine builder said i should try 256 inlet cam with a the next size up exhaust cam say like a 264. I gonna be running a 2540 turbo so i not aiming for huge power but apparently running slightly bigger exhaust cam helps earlier spool up. I believe to if i go bigger than the 256 cams i would have to fit heavier valve springs, is this true?

I appreciate any input

yeah i've been thinking about the 2540. I've got it on my rb20 atm. 220rwkw but i'm definetely sick of the lag. Love the way it comes on but only happens at about 4100rpm. Upgrading to rb25 shortly so cheap options just to bolt on the 2540 and i'm half curious to see just how it goes on 25. But i have thought of getting a 3071 or 3076. Would a 3071 be more responsive than the 2540? I didn't realise 2540's had such a bad name for themselves before i got it.

      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

      S15 Spec R

      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!
