Has anyone dealt/ have any experience with Fred @ turbologic in port kembla.

how good is his work with hi flows/ custom made turbos etc

Theres a big difference in his prices compared to same sorta job GCG does.

Cheers

That's because they will be bush bearing not ball bearing cores.

Same as every other cheaper hi-flow, they are cheaper due to the core

Confirm what sort of core he uses in the high flow if thats the path your going.

But anyway, GCG are usually overpriced so i wouldnt be suprised if any number of people can offer the same product for cheaper price

Do not hesitate mate, Fred at turbologic is an expert in turbochargers. His work is top quality and very well priced. This is one place that I know of that cheap prices doesnt mean cheap products. he caters for all new and custom turbochargers for anything turbocharged.

I dont know him that well but had to respond to your post as my experiances as a customer at tubologic are worth the effort to let everybody else know about.

good luck

Fred is a champion!

Nuff said! i've used him many times for friends and myself! great work and great service!

He did a repair on my n1 turbos garrett didnt have the stock core parts for a while, so we put a larger core in thus giving me gtrs with n1 covers

thus creating my response machine :)

Ok so basically i was looking at upgrading a R34 NEO GTT Turbo to a HI Flow.

(Yes i am aware there are nummmmmerouns amounts of topics on this to which i have gone through and read, quite informative also)

I spoke to Fred, and he does a plain bearing upgrade using garrett cartridge etc and rates the turbo to be up to 450HP.

Now i had a squeeze at differences between ball bearing and plain bearing etc and came to personal opinion that if you regularly service with GOOD oil and also cool down your car after giving it a thrash, then the plain bearing is fine.

BUT what i would like to know, is how big a difference is the response levels (down low moreso) between the two bearing types.

Thanks heaps guys

Go the ball bearing instead. I'm sure he can do that option. I spoke to him about it ages ago.

I've only ever heard great things about Fred's work.

I'm about to send him a HKS turbo to have the front wheel dressed and balanced.

You wont find a more helpful guy. And he's supposed to be brilliant at what he does.

And yeah, GCG is definitely overpriced.

Thanks for everyones help.

This is definitely not a thread to have a go at GCG because all i have heard is great work from them. so kudos to them.

Just needed an opinion of the work that fred does and also main pro's and con's between ball bearing and plain bearing.

Thanks again

+1 for Fred.

Just expect to chat to him for a while if you have a question.

Did some research on types of bearings, and what 'bearing' (excuse the pun) they have on how your turbo performs in terms of response etc. I would appreciate everyones thoughts as i am NOT an expert and can only research so far.

Is paying the extra $$$ for BB really worth it after reading this?

The type of bearing does NOT affect at what rpm the turbo begins to come on boost, not at ALL. Thats the biggest thing they dont mention. People hear the word "spool" and suddently think a BB turbo will come on boost at half the rpm of an otherwise identical one with a plain bearing. Wrong. No difference at all.

What a BB turbo WILL do is go from say 1psi to full boost faster than a plain bearing turbo once in the boost threshold (the boost threshold is the rpm level where you put your foot down, and it comes on boost, as all engines have an area low in the rev range where it doesnt boost at all), but even according to the biggest promoter of them, Garrett, its only 15% faster, FIFTEEN PERCENT, thats, well, hardly noticable. Think about it, your at 4500rpm, you put your foot down, how long does it take to hit full boost? Blink of an eye? Maybe a second or even two if your car's really laggy. How much has spending maybe double the money buying a BB core turbo gained you? Yup, 15% of one or two seconds, thats less than a blink of an eye, certainly nothing a human being would really notice, and nothing that would make a dent on a performance time.

Dont get us wrong, is money was no issue and we wanted the perfect car, we would say BB all the way, but unless we all win the lottery (and then im sure we wont be worrying about this!) money is an issue, and paying an extra 500quid for something you wont even feel, just because the salesman told you its good, is frankly ridiculous when there are SO many more effective ways to improve your performance or indeed, increase spoolup speed.

Wheel size and type (compressor and turbine), turbine housing a/r, exhaust gas temperature, turbine housing style, and much more all can make a HUGE difference to when and how your car spools up, much much more than what a BB core will do, and usually much cheaper too.

Basically, dont worry what core it has, worry it is the best specced turbo for your application (ie not the huge a/r old junk at the top of this page, for example!).

Data Table: http://www.ian.chisholm.clara.net/dbb/t67p...comparisons.xls

Results: Around 400ths of a second differernce to hit 1 bar of boost between ball bearing and journal bearing. SFA really. Your datalogging may notice it but you wont notice it on the road during gear changes. In Even in circuit cars, there is ample exhaust flow to keep the turbo spooled during gear changes. Spool and response will certainly be noticeable on the street but once its on boost, the difference could be SFA.

The real technology in Garrett GT BB turbos is in their wheel design and housing options.

Ball bearing is a great - but even for a big single - it may not be worth the extra premium for a big single turbo due to the wheel inertia and design providing most of the 'lag'.

In Drag racing, you will not see the benefits of the BB turbo in the 1/4 mile time as your converter should be able to make boost on the line and leave the line with boost. In a manual form, you should run an anti-lag system to get the boost up.

    • We have a huge update coming in the next few months, version 5 of Invision will be released. I'm holding off any changes until after this change as I'm not sure what features will be removed or introduced.
    • Yeah, plenty of air flow, there is a dedicated path that feeds the air in to the OEM intake tube behind the bumper As for a "tangible effect", maybe, but getting the pod/intake air out of the hot engine bay is worth it psychologically to me, even if it gives no performance difference, so the tangible effect in my Lizard brain saysss yessss  In the end, to me a tangible effect isn't always about performance, sometimes it a sound or a look, or even a...... feeling  Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga
    • yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching
    • Quite right, if you make it to that pension you deserve every cent
    • Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
