Sounds like heresay to me. Plenty of people with RB26DETTs running more that 300kw (at the wheels) without issue: you just *must* make sure that all the ancillary systems are in place to support that kind of power and all necessary modification have been made.

If your really concerned, source an N1 block which has thicker walls and different oil galleries designed to protect the block from cracking.

Get Zoom, 08/04 mag, has a Phat 350Z 334kW twin-turbo on the cover blue 350Z.

It has an article about RB26 tuning, and they are saying 400kw@rw is what you can get on stock internals, then you'll have to start uping the internals and start looking at some other things as well.

RB26's are very strong engines, it wouldn't be so well known if it wasn't.

Up get take the RB26 over 1,000hp and over 700kw@rw, companies can sell 1,000hp RB26's wouldn't be cheap at best though.

Ha biggest crap i have ever heard.

Teh GTR Block can NEVA crack :)

All serious now, mate there are guys making well over 900 HP and the block hasn't cracked.

Oh and if you go to supra forums dont type the word GTR.

The Supra Boys seem to get a a bit of bullshititis and upset.

Must be because they worked out they bought the wrong car.:)

Hi guys,

I've seen plenty of supras making more power than gtrs with stock internals, they are doing 9s (street tyre) in the US the record is 950rwhp on stock internals, there are countless making 700 to 800hp, I've never heard of a GTR doing this on stock internals or not even near so come back down to earth NISMO 400 R N1, In my point of view the supra has the upper hand as you can do much more to it with less money. Its not hard to see that the market has a wider range for the Skyline/ GTR within Australia as.

my friend has cracked his block...i'm pretty sure he told me he was running 500+whp though.

i have been told to be wary of the engine twisting when making in access of 450hp? i think getting stiffer engine mounts would help. there's also something that looks kinda like a shock absorber which kills or minimises the twisting.

Yes, Nismo makes a series of mounts for the RBs, and there are "anti-twist" bars. Of course the best option would be to get an N1 block...

      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.
