Hi guys,

im thinking of buying a blown turbo. Its 34N1 1441-AA403. It can pump 500ps. Is it worth it to get it high flowed? Im looking into making 320kw@4wheels. Or should i just save up and go for a GTSS? Im thinking if im getting it highlowed for the blown turbo i will put in a journal bearing instead of a ball bearing for a quicker response. Where can i get the turbos highlowed with journal bearing? And how much? Is it worth it and the effeort of getting the turbo higlowed? Differeces in perforamnce compared to the cost of highflowed and a GTSS?

My rig is actuall a 260rs which is basically a r33gtr. Will be using the rig only on the street though. Appreciate for any opinions or comments.

Journal bearing is LESS responsive than Ball Bearing.

As far as i know journal bearings are used for high speed applications. And its more precise in terms of the siiting of the shaft and the bearing itself. In a ball bearing it will have a minute play in the shaft due to the ball bearings.

These guys will do it. But make sure you explain to them the benifits of journal bearings, as they might try to sell you those overrated ball bearing units. Also try to stay away from steel exhaust wheels, get ceramic, much lighter for faster spool. :laugh:

plain incorrect......

GARRET have marketed it quite well but at the end of the day it is just another way to get the same result. If journal bearings are still the preffered choice for all jet fighter turbines (due to same performance better reliability) i will continue to take the debate with a grain of salt.

i dont care either way as we sell large amounts of GARRET and Journal type turbos :ph34r:

as for your hi-flow dont bother, i would just save up and getting GT-SS's as they are small enough to get the 320awkw you need with excellent response..

Not quite ;)

I was talking specifically about the turbo's he wants to sort out.

Not a blanket statement that takes into accounts airplanes...

LOL!!! yea thats what i thought too. All high speed turbines and jet engines uses journal bearing like my irrgation pump which is a groundfos. pulled it aprat the other and its got a journal bearing at the bottom of it.

Now what the maximum limits in terms of Hp or kw can i get the car into with stock internals? Long term realibitlity. Cos thats whats going to govern of which turbo to get.

Im cureently looking for parts like :

800cc injectors

bosh 044 fuel pump

FRPs

AFms

havent decide which turbo yet?!

      Feedback on Carbonetics: R34 GTT cooling panel

      By IM-32-FK · Posted

      @DraftySquash @Duncan he's not talking about the part that sits against the radiator support, he’s talking about the lip that sits towards the front outside of the car. anyway I had a look at other cooling panels and came across this one https://justjap.com/products/carbing-radiator-cooling-panel-plate-nissan-skyline-r34-gt-t?variant=37829684134087&currency=AUD&utm_source=google&utm_medium=organic&utm_campaign=Advanced feed&utm_content=Carbing Radiator Cooling Panel Plate fits Nissan Skyline R34 GT-T (Coupe)&srsltid=AfmBOoonzPDKqe9NgKi5U0AkFc2XvbXETGmNWvfNcyBT5DUZagMYHg9DZ70 if you take notice it’s the same shape.  well thankfully the justjap listing has a description and it says : - Nissan Skyline R34 GT-T Coupe (M/T -07/2000) this means it’s specifically for a s2. S2’s have different front bars to s1 so that lip with the 3 holes are *probably* mounting points for the s2 bar. im not 100% sure but im almost certain it will still fit a s1 bar

      Everyone is too used to learning from places like HPA "how to tune" and what to expect at what point, rather than being able to see "The computer says I'm in cell with Row = 8, column =4, and I can see my fuel is lean, so lets add more" Everyone wants "real units", which helps for someone picking it up for the first time and seeing how bad the tune is if they're not used to touching it.   However, I think for most of us who want to play with it, you're 100% right, we're only needing to learn about it for OUR CAR. Which makes it great, and we don't need to care what the real values are, we just need to know which cell it is, that's causing the lean or rich point, or that we want more ignition timing or less. But again, everyone wants everything super you beaut and nearly self tuning, with VE maps, and a billion compensations...   Though then there's me over here when I'm doing reverse engineering work just reading data in hex format that most people couldn't work anything out from. Yet I can see what's going on.
