G'day ppl could I get pointers on a full rebuild of anRB@% GTST Series II engine for 500 to 1000 hp. I'm after horsepower and reliability together I dont want to be breaking somthing all the time lol. How much roughly could the rebuild cost aswell rough figures of what other ppl have spent and the ideas aswell would be helpfull. Im also south of brissy qld so any shop recommendations would be greatfull to.

For a start go to the Forced Induction section and look at the RB25 turbo upgrade thread. You will see what people have done to their cars to get more power. Start at the end to avoid a load of outdated gear.

And there is a huge difference both in power and in money between 500 and 1000hp so have a think about how much power you really want.

LOL, reliability for what use?

You need lots of cubes, lots of strong parts, and some boost.

What transmission and drivetrain you using, that stuff can start eating itself at 400hp, let alone being reliable at 500-1000hp, for "some" reliability I would budget around 60-80k, easy, maybe more.

Your also going to need a "spare stash of cash" for when your "reliable setup" breaks.

And it will.

What can you do? Cmon man, this thread is ultra vague!

Well at the moment mate I'm rebuilding a LS3 engine out of a senator from ground up and my skyline is my next project I was just seeing what other people thoughts were hoping there was people on here to throw out ideas I might not have thought of

Nothing wrong with the RB diff.

Really mate I haven't really had much to do with the RB parts as a whole I been into more V8's but I am really loving the RB's. I have seen the limited slip upgrade for them is that the better way to go?

      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!
