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..

plain incorrect...... broad general answer made with no understanding of the physics behind it.

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?!

    • Hi guys, long time no post as per usual! It's been a busy year so far, the biggest thing being a new job.  After 28 years in the automotive industry I decided it was time for a change.  I was losing faith in the industry and where it's heading.  Now in a completely different industry (electrical) working for a company that manufacture water pump contollers.  Not as sexy as cars but it's an interesting,  challenging industry. I now don't work Saturdays which is a bonus!  It's still 50-55 hours a week but having Saturdays ack after 28 years of working them is awesome!   No news on the GT-R but i did decide to add some more JDM goodness into my life....           1990 300 ZX.  She's not perfect but for a 35 year old car she ain't bad!  Just going to tidy it up a bit and enjoy it.  It's currently auto but will start stockpiling everything for a manual swap. It WILL distract me even further from the GT-R but im hoping not for too long! It somewhat proves a 6'8" freak can fit in a 300 ZX.  Sort of...  I drove it home from the previous owners house in Melbourne via Black Spur and Merton Gap (2 awesome bits of Victorian twisty road) and it was amazing!  Handles so well!!!   I don't think it would be worthy of a full build page but I'll post up some of the upgrades here if anyone is interested?  Cheers guys!
    • End game is to: - Remove all the slop from old worn parts - Adjust setup so that the wheels actually fit and the car is drivable (currently it is not because of the extreme rubbing on the guards).   Progress over the last couple of days, removed the rear hubs! Next steps: - Buy bushings - Replace bushings/bearings on hub - Reinstall
    • Cracked deck  And other cam snap stuff   
    • A few random issues have popped up since my last update. My WMI pressure sensor failed within about 10 minutes of it seeing liquid. It was a 20$ China special, so I'm not surprised. My name brand replacement should arrive today.  My power steering assist also decided to crap out last weekend. The usual, works for about 60 seconds after starting the car then I lose it. I dusted off my old copy of NDS and connected to the HICAS ECU. Code 4 for assist solenoid.... I tested the solenoid and it's fine.  I knew the day where my HICAS ecu would crap out would come, and I welcome it. It was the last HICAS part on the car that is now in the bin. I've ordered an SSR and I will control the power steering solenoid with my Haltech ecu. It will be nice to have proper speed referenced assist again after all these years.
