hi

i own a 1996 nissan skyline r33 gts-t and i was just wondering how much power can a stock turbo handle?

what mods can i get to make my skyline fast without blowing up the turbo?

i was planin to get a front mount intercooler and a aftermarket computer would the stock turbo handle that?

around 200 - 220kws is all it will take, and not for long!

Mine is at 203kws running at 15 pound right now, I've already got a new turbo though so I don't care if it blows.

It could live on 180kws for a long time, I wouldn't put it past 10psi if you want it to last.

power figures are all depending on other mods as well...

I thought that aswell.... until i saw a bloke have to rebuild his motor because it ingested the busted turbine when it finally blew..

I'll bet you a steak sandwich it wasn't the turbine. Engines don't breath in reverse and any chunk large enough to go back through the manifold after the explosion is not going to have a shit show of getting between the piston and bore

The highest I've seen is 223rwkws and it lasted about 20mins. Mine had 215rwkws on Dr.drift remap using a RB25Neo turbo and it was missing half of the turbine fins when I took it out 3 weeks later.

adrian has made around 270rwkw on the standard turbo

this was with NOS. so i think the question the original poster has, is what boost pressure kills the std turbo

its around 12psi. 12psi is the ok / risk level. it may work fine for years or it may shit a bearing in 20 minutes

ive had mine at 0.85kgcm2 for about 5 years now, got car at 58k and its now got 215k on the clock and still std turbo at 0.85kgcm2

so its luck of the draw

power doesnt kill the turbocharger, excessive heat, shaft speed (from running mega boost) and poor tune (excessive egt's) are what kill the turbocharger

Is that a good idea? What if it fails catastrophically and bits get sucked into the engine?

Edit: Opps I see that was partially answered but still bits of turbine blades all through the 'zaust/cat can't be good, plus also if the compressor side fails couldn't you at least get a load of oil fouling up intake etc

i got my r33 series 2 running on 12psi...175kw atw..but only drove it for about 4 hours on 12psi till my coilpack failed...but im looking at putting a remaped ecu so il be getting around 200kw on my stock turbo, and my tuner said it will be ok.

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
