Stock R33 Series 2 Turbo

[and3_3]

12psi is fine as long as its taken care of which isn't hard to do.

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

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

Not if the owner drives like a pussy and "1 bar" is just for street cred

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).

[joeyjoejoejuniorshabadoo]

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

[Kinks]

Hundreds of references online point to it being a nylon wheel and having felt a S2 turbo with my hands the compressor does not feel metallic at all.

[PM-R33]

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).

[joeyjoejoejuniorshabadoo]

if he means stock aussie v8's then yeah i'd agree

[JonnoHR31]

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

Then your area is wrong

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.

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.

[ShiftyTys]

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.

[SCR48]

i got stock turbs and running 13psi with a Vi-pec ECU... i should be able to get 15pis should i safely?

[Wacky Dee]

how much did the vipec set you back if you don't mind me asking? what about the tune ?
