How many RB25's are out there making 600rwhp reliably? I am in the process of getting mine built by a reputable engine builder here in W.A. I just don't want to throw my money away, it will be getting built with good name brand parts (CP, Nitto, ACL etc). Is 600whp too much of a stretch for a 25 long term, block integrity etc? Anything I should look out for, or know before pulling the pin. 

I know about the RBs oiling issues, and have read the oil control thread. My build will get a 9L sump, proper restrictors, strengthened oil pump/collar, good baffling and my r33 already has a accusump setup in it.

Like anything depending on how you drive and maintain it. 

If your stressing about it lasting and/or breaking gearboxes probably best to not go chasing numbers. 

Gotta pay if you want to play

I'd take a responsive 300-350hp any day over a 500hp+ 30year old import as a daily.

Why is WA still imperial not metric? About 450kw, right?

Anyway, assuming it is not racing of some sort, it should be fine for street and twisty driving because you just don't use the whooshy end of the rev range very much at all, perhaps once or thrice a day or week.

Gearbox however is at risk depending how you shift when you are pushing the car hard. Take it easy on full power shifts and you should be fine

Please talk in kW... we aren't American.

If you want to talk in HP, make sure you convert everything else into the useless imperial system.

450kW for a built motor would be a walk in the park, I would be more concerned about your gearbox going bang :)

      Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.

      Strange issue RB25DET wont start

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?

      I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.

      I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
