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

      Uncle Duncan Yeap, FI Interchiller  Works well, normal IAT's cruising with the WTA only went from 50°c+ to 25-30°c with the interchiller  Before, when on it hard, the IAT would see 80-90°c, now, the highest has been was around 38°c IIRC IAT is measured under the blower hat I recommend it for the street or strip where your only on it hard for 10 or so seconds, but it wouldn't be efficient for sustained track use as it would heat soak from the AC turning off or whatever it does during WOT to protect the compressor It really needs the AC running for it to not heat soak and keep the WTA coolant chilled My WTA coolant temps when just cruising is around 2°c

      Hey Mark...sorry to interrupt your career change to hair dressing... but...did you ever fit the interchiller to the commodore, and if so how was it? And, who made it?

      I've been pondering this, I really enjoy the convertible thing, for me, it's like riding a motorbike, without all the issue of riding a motorbike, mainly, my old sore arthritic joints getting beaten up, and, being able to do it in shorts and a T-shirt and not needing a helmet and all the other gear required, especially like wearing jackets and pants in the summer, or needing 6 layers of cloths in the winter, or not having wet weather gear handy when your 100km away from home on the bike when it decides to start raining As for the hard top and its Coupe look, whilst I do lose all that open top feeling that I really enjoy, from my experience with the NB with a detachable hard top, the cabin is a much nicer place to be, the difference in noise for one, a hard top quietens down the interior, alot, with the soft top up or down it's pretty noisy, which, after 5 or so hours, can get tiring But, as you stated, the detachable hard top totally changes the look of the car, in a really good way, and for me, the look of a detachable hard top is so much better than the PRHT which looks more like a after thought with its weird bulbous rear roof line For me, the minimal effort of putting in on, or storing it after removing it, is well worth the time and effort for the look alone And yes, I'm sure the next owner will be grateful for it as well.......
