R33 Standard Turbo

[zero'sR32]

hey guys... im relatively new to the skylines scene around here

ive got a rb20det with a r33 turbo in it... i was just wondering what exactly the r33 turbo is... stats/ figures... brand etc....

ive tried searching thru the forums and found nothing... maybe im just an idiot but yer... just a general qs...

thx... would be a good help...

It's a T3 Hitachi/Nissan hybrid. Ball Bearing, ceramic turbine wheel which starts failing at around 11PSi

its not a garret? i thought it was...

its compressor wheel is steel, while its exhaust wheel is ceramic, just like the rb20 turbo. this means that at high boost it can generate too much exhaust heat and the exhaust wheels can delaminate and separate from the shaft. That's why people say generally they have a maximum boost that should be run through them without damaging the turbo...

on an rb25 engine, its good for 11-12psi max

on an rb20 engine, its good for 14-15psi max

its a great little upgrade on the rb20 motor as it provides more high rpm pull without getting too much lag down low

PS welcome to SAU

I've seen them fail at 10psi and seen them NOT fail at 13psi plus 100hp bottle. You just need to get a good one. The advice about 12psi or so being safe is probably sound, though.

or be a man and ditch the hitachi special

ive run mine at 1bar for almost a year now, including a lot of track work and hasnt failed me.

the S1 turbo has steel compressor and the S2 turbo has nylon. same specs though

Not this argument again... i cant find my keys!

thanx guys... clears out what i wanted to know... atleast its better than the stock rb20det turbos... mines running stock boost atm but i got 3 stage evc set to 8/10/12or14(not sure) and everything is fine when i drive it... only problem is a bit laggy... kicks in at about 3500 rpm or so... but fun cause its so loud!!

Is the r33 turbo rele ball bearing? i dunno why but i thought it wouldnt be, plus i think ive heard otherwise at some stage or another, just looking to clarify

[izataskyrine?]

eh ur turbo kicks in at 3500rpm? my HKS GT2840 is boosting from about 2000rpm why so high?

because if you read the first post yo would see he has the rb25 turbo on a rb20. rb20's don't spool as early as 25's.

and yes they are really ball bearing. it is slide's highflowed ones that aren't. the only difference is the spool up time. once they are up and going they perform just like a ball bearing.
