I am very confident I could pop each and every one of those 3 you have had on an Rb25 within a day , given a go at them :blush:

how exactly? without increasing the boost it'd be the same as every other day for the last year

not really worth it but myne made a touch more peak power on 15psi than it did on 13

bolt on ebc so it actually holds 1bar till redline (big difference between getting to 1bar and then dropping boost as revs climb) and then take it to the local circuit on a sunny day. guarentee I'll get you 3 dead turbos before the end of the day.

It's the same bleating you get from some GTR owners who don't know better and it's also actually really a stupid way of increasing performance given the risk.

When the ceramic turbine lets go you can end up 'dusting/sanding' your piston bores with ceramic particles. There are again plenty of examples of 'damn I lost my turbo......wonder why my car is using more oil and compression is down?'. I had some very old GTR turbo's let go.No suprises, it did just that.

I'm not being a kill joy. You can still run a high 12 or low 13 1/4 with just 10-12psi in an R33 or R32 with one of these turbos.

I have.

Want more power?

Go and buy a buy a bigger turbo with a metal turbine easy fix.

I have only heard of this with GTRs, possibly because the twin design is more susceptible to allowing particles back up the exhaust headers. Does it happen with GTS-t's too?

The gtr's are more likely to get hurt but, the same risk is there.

So, judging by this thread, it is 100% true that the Series 2 R33 turbos do NOT Have a ceramic turbine, but rather have aluminium?

And therefore can be boosted higher than a Series 1 turbo?

I'm posing this more as a question, rather than a statement as I do not know the correct answer.

If someone can confidently confirm this, please go ahead.

100% wrong. See my first post in this thread (#5).

no they both have a ceramic exhaust wheel. (the back one)

s1 has steel compressor wheel (the front one)

s2 has a "nylon" compressor wheel (the front one) which someone (trent i think...cbf looking) mentioned was actually aliminimum with a nylon component somewhere along the lines

12psi

stand alone ecu with aggressive tune

good tyres

pineapple, camber, castor kit

short shift kit

intercooler

good 3" turbo back exhaust

cold air intake

there wont be much on the street that can beat you in this setup

should make around 190-200rwkw

Hmm not sure about your area you live in Paul, but around here 200rwkw in a skyline just doesn't cut it (for a street car).

i ask how you'd do it without increasing the boost and you say ur gna bolt on an ebc so the boost doesnt drop off, hence increasing the boost :)

probably never get driven with stock turbo again anyway, will have a gt30 within the next few days

If you say 1 bar we mean 1 bar do we not?

If you go around telling people that stock turbos can hold 1 bar all day, then neglect to tell them you didn't mean " 1 bar all the way to redline". They may own a skyline with an ebc and then on your good advice will lead to a nice dead turbo and possible engine damage.

Adding an ebc to 'hold 1 bar' is not "increasing boost" as far as this argument is concerned. It's 'holding boost'.

The GT30 will be fun. :D

I wouldn't bother running more than stock boost unless you get a powerfc or tune your factory ecu as you'll run into R&R issues pretty quick and the car will run like crap.

Since you're in NSW, come down to Sydney .. Toshi can remap your stock ecu for < $500 ie. fix up the AFRs and ignition timing. Much cheaper than a powerfc tune and will allow you to run as much boost as you feel is safe, i'd recommend no more than 11.5psi - that's what mine's set to but I have an R34 GTT.

my car only has pod filter and a boost controller set to 10psi running over a year now. Making 150rwkw at least. Just had 9/12 manifold bolts replaced and turbo gasket replaced due to all of it being broken or cracked etc. Leaking heaps of air. Haven't dynod with problem fixed yet. But yeh. Initial duno was 150rwkw with just those mods. Hope that gives u some kinda indication.

      He obviously had his reason for flipping you off. I wonder what it was...

      I have to agree like, yesterday, I was driving down the warringah freeway towards the bridge when this jackass driving a beaten up Honda civic cut me off so suddenly it made me almost yank the wheel to avoid him hitting my car. Honestly and he had the NERVE to flip me off (or some other gesture Idk). Im a calm guy, but really some people just dont deserve to have a license, let alone be allowed to drive on densely populated roads/highways. If youre gonna cut through lanes at least use the damn turn signal

      Mistakes were made, my R34 Story

      HPA do an interesting video on tuning, and Adrian shows on the dyno, moving from 10:1 to 12:1 (And I think even 13:1) and the power moves SFA. However, a couple of degrees of timing has a HUGE impact. Exhaust side of things will more be the length of the exhaust and how many bends and turns you have. The straighter you can keep it, the better. By a lot. Oh, and getting the diameter right. Bigger isn't always better. Going to big can actually lose you power.

      I have to say, most people I see on the road fit the bill of atrocious drivers. Whether they be cowboys in their dual cabs, bogans in the Commodores, or the soccer mums. Pretty much most people on the road put zero freaking thought into driving. Barely look further up the road then the end of their bonnet, and have never even thought about how catastrophically wrong shit can go, by doing what they all deem as normal driving. Especially their late braking, racing to stopped lights, and sitting half a foot off the bumper of the car in front at 110km/h. Wanna know what's even better? By the time their kids get to be old enough to learn to drive, they've already got in the back of their brain what is normal driving, how annoyed you're allowed to get at people etc, and then their parents who actually have zero freaking skill at driving (Even though they constantly say "I've been driving for 20 years and never had an accident!") teach the little twerps how to drive, or should I say, how to make a car move. Literally watched a parent teach their L Plater, on a 4 lane freeway, that you just slam the brakes on, and push your way over, even with a B Double bearing down on you, and that's how you should drive, rather then, just keep going to the next exit. Same shit happens all the time for side streets etc, watching numpties pull dumb shit turns pushing across 3 lanes of traffic, rather than just go up the road another 30 seconds, and take the next turn that'll get you to the same location... Oh, and the damn right lane bandits. Or the retards driving along with their headphones in, and can't hear the ambulance or fire truck right up their ass about to run them over...   Pretty much, people drive on the road, like ego centric f**ks, and don't actually think how dumb shit their driving is, how it could easily kill them or someone else in a split second, or at the very least, how they're driving is contributing to all the shit they're bitching about on the road, like shitty congestion!
