in my other thread people were telling me not to boost it any higher than 12 on the stock turbo.

curious to know what everyone thinks is an ok amount of boost to push through the stock turbo, because ive herd anything from 10-17

car is currently on 10 but contemplating putting its high boost setting as 15.

stock turbo on mine i had it up to 14psi.....but since after 4800rpm the boost would drop down to 12 and held it flat till redline....

so no point boosting it to 14psi....12psi is much safer and definitely not 17psi

Extended periods on high boost blow the turbo, not just setting it to 17psi.

I could set my turbo's to somehow boost to 30psi, but I might just put my foot down til 10psi then back off... that wont blow the turbo.

But if I kept my foot down at full 30psi boost, that'd blow the turbo.

So your mate wasn't driving his car hard enough to blow the turbo :rant:

Plenty of stock turbos have died at even 10psi when on the track under decent temperature and load .... pretty sure that's how the HPI R34 blew its stock turbo when they did their build-up. 17 is insane and would not last long at all.

so as a daily driver the highest would be 14 if im not flogging its guts out everytime i drive it?

and its safe to say i drive like a grandma with the very occassional spirited drive

*edited* cheers for the advice, just trying to find the highest/safest amount i can put through it when the car wont be thrashed off its guts on a daily basis

My old turbo on my B6T-equipped Mazda could handle 15psi on the odd-occasion. That was even with a side-mount cooler.

Just upped it, flogged it for a few minutes then put it back to 10psi. It happily ran that way for years until the chassis cracked.

And that was a stock little turbo that's only designed to run at 6psi.

off topic a bit, its actually amazing how helpful the import scene is compared to the holden scene towards the new guys.

ive asked several dumb questions on this forum, and had nothing but helpful remarks back.

on other certain forums i wont name, you ask a dumb/basic question and they bite your head off.

so cheers guys.

as i said before i ran mine on 14psi....coz i hardly hit limiter everywhere.....the car ran on that setup for about 2 years without a problem.....till i upgraded the turbine

make sure though you are putting 14psi through a front mount intercooler instead of those poxy little side mount coolers mate

plus i had other mods to go with it like fuel pump, coilpacks etc and a full tune and it made 214 odd rwkw on a el stocko turbo

aren't they around the $1500 mark.

only starting to get cash flow back after a few months without a job. so not looking to spend big $$ just set.

although i can get the labour for pretty much nothing and get things like bigger turbos/injectors for the price of a carton

    • The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.
    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
    • Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.
    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
