Hey guys so i finally installed my new highflow! drove around probably 20kms-30kms , it was great.. the power is unbelieviable pulls like crazy!! but then suddenly it siezed up! so i had to drive home checked it nothing looked wrong . Now could this be due to starvation from the oil? not much oil is coming in to the turbo? Is there a procedure we have to do before we install back in the turbo?

Thanks..

What sort of hi-flow?

If it was bush bearing, i do believe you cant just bolt on as the stock lines do not slow enough.

Similar to the Slide hi-flows that were being done, that required the oil line or something to be enlarged.

You didnt get enlarged lines or informed to put larger lines on there to start?

Or perhaps they are not needed... but then if others need enlargement i cant see how any other would be different regardless of warranty because its still a head fk to pull a turbo on/off labour wise

Interesting....

recently had head work done, and ended up with a cracked head.

while in diagnosis mode there was too much oil going into the Slide bush bearing highflow, due to tomei restrictors in the head

whilst that was fixed and the correct flow was managed (get a good tuner buddy! BoostWerx for the win) oil was still being burnt

new head was reflowed and ported etc with my stuff moved into it

retuned on dyno, with turbo copping a beating for 3yrs, for 226rwkw

bush bearing turbos arnt that bad. for $600 + a dead turbo its a great deal!

MUST ensure correct oil flow, but even with too little / too much you've got a window of opportunity to fix the issue before all hell breaks loose

good luck with the new oil lines

Ive always done atleast 100k's before i put the foot down to run it in. Bush bearing hiflows are crap though in all honesty.

get a garrett bb item now

BAHAHA its a known fact that bush bearing are far more hardy than BB.... dont post crap.

Don't let sydneykid catch you saying that :thumbsup:

he had a massive rant in slides thread plugging GCG lol.

Will they autopsy the turbo when its out?

Ah now now Trent :P

You know as long as lower shaft speeds and oil pressure is observed then they are OK.

Soon as you go above things (or below) then things start to fail.

Same can indeed be said for ball bearing turbo's, infact BB items are overall more sensitive... fact remains though that anything can be killed. :thumbsup:

On a side note, when are you going to attend a damn cruise?

This is basically what that was:

25-11-06_1316.jpg

The high flowed turbo was fitted with stock oil line and bolted up with a stock oil feed screw. (on right) We did not carry out this installation.

Problem was on the standard oil restriction valve. The Turbo siezed up, without blowing smoke. It needs to have as much oil as possible to flow. Braided oil feed line is required to make this work.

All internal bearing components used in this high flow are original Garrett

soon :) we are revising the DA car into a neat streeter, same running gear but without the big kit, wing etc.... hope to have it completed in about a month.

so do require new oil lines or larger internal banjo bolts for bush bearing turbos??

since ive got one coming from hypergear too..lol

and i was planing on using the stock lines..but new gaskets.. :(

i found out coz it bush/sleeve bearing turbo core..

u cant use the stock lines or banjo bolts..

it requires more oil than bb turbos...

u got get a new braided line with new fittings

dash 4 is size u need..

i got mine made up 2day for 80bucks with speedflow fittings..

which was done by GoGear in Perth...

no im just waiting on the turbo :D

what bolt is that on the left?

is that the one uz fitted to Geraus car??

whats the required inside diameter of the banjo bolt or fittings??

coz my speedflow fitting are the same size internal diameter as the one on the RIGHT(stock)..

but without the restriction in the bolt...

that will be fine, the restrictor on the stock fitting is about 1-2mm and the speedflow one is about 4mm from memory.

    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go. 
    • More so GReddy oil relocation kits, sandwich plates, etc. all use 10AN fittings. And same, I've only used 10AN and my car sees track work (circuit, doing laps, not 10 sec squirt business).
    • street use or race track, what hose size and why? what factors change with the hose size options ?   see most comon is an10. when you see most oem external coolers are closer to an12? does high volume oil pump like nitto need an12 or 10 be just fine
