Putting On A 2nd Hand Turbo

[Birnie]

Hey everyone,

Just got hold of a 2nd hand turbo (HKS 2535) which seems to be in good nic, not that i'd realy know but it looks good and bugger all play in it.

It does hae the usual black crap over the exhaust blades and some discolouration in the compressor blades but no chips or anything.

To people have have bought 2nd hand turbos before, were you confident in just whacking it on or did you get it checked out by GCG or cleaned/balanced before hand??? (or anything else i haven't thought of)

Any help appreciated.

Thanks.

for piece of mind i would have it serviced, saves you the hassle of getting it re done and possibly damaging your car once fitted and run with no tests. worst case they can say that its either f**ked or its fine, then u strap it on and give it a boot full!

Once they pull it apart, you need a rebuilt kit anyhow, so then you've rebuilt it

If there is minimal side-to-side shaft play, and no forward/back, then it should be ready to bolt on and enjoy, it might not last as long as a new one, but then it might last 3-4 years without a problem.

Thats just the nature of a 2nd hand turbo

if it looks and feels good do it.

bolt her on if she shits herself. rebuild it..

either way turbos go. so more than likely it will go later on.

a blown oil seal will cause low oil pressure in your motor. one track day with the blown oil seal WILL result in a spun bearing on a tired motor.

Thanks guys for your replies.

I think I'll just throw it on, when i figure out how, and see how it goes and keep the standard one the shelf for emergencies.

Not if you reasonably proficient in checking the oil level before/after/during a track day etc.

Only takes a few secs, and you'll soon know if its eating oil.

If its eating enough to the extent you can see it out the rear, then other people will generally tell you as no-one wants to see a car fail

its still very risky. noone will be able to tell unless you're on the track and by the time you've done a lap it could be too late.

when you get your turbo re-fitted, go for a drive, keep your eye on oil pressure, give it a little hit here and there, try get a mate to drive behind you to see if you get any blue smoke out your exhaust. then stop and check for oil in your cooler piping too.

But that could be said for any turbo at anytime if you think about it dude, its not just because the turbo is second hand.

Its a risk every day the car is driven

yeah i know what you're saying but with a 2nd hand turbo you dont know how bad the wear is if an oil seal is blown. for example, my car would drop to almost 1 bar of oil pressure! (i took it off the road as soon as it did though).

that was after weeks and weeks of driving with a known blown oil seal, out of nowhere i had almost 1 bar of oil pressure.

on a friends car.. he was running quite rich as well as having a blown oil seal on his turbo, driving behind him it looked black. we only found out he had a blown turbo when we were replacing his fmic.

so with a 2nd hand turbo where you dont know the condition of internally, its hard to really trust if its in good condition. so like i said, look for warning signs, and dont ever take chances with low oil pressure or YOU WILL GET STABBED.

If you guys are still reading....

Getting close to putting it on.

Got hold of the right-angle pipe coming off the turbo which i think is the last bit i needed.

Braided oil lines.. i know these get mentioned for after market turbos. Mine came with 1 and was wondering if that's all i need...ie, do i re-use all the other lines from my original R33 turbo?

use the one that came with it if it was being used previously with no problems.

its hard to tell if the water lines will fit on, but from what i can see, i dont think they will - the fittings look different and the standard ones arent flexible enough to bend to where you'd need them. get some made up - allow around $80-$100 for each one you need made.

you might want to turn the oil drain pipe the other way, it should be curving towards the block, not away from it.

If that's a hks 2535, you have to use that line or get a new braided line. The stock line won't bolt up.

Just out of interest what is oil pressure is normal for a warmed up car? Mine runs at just over 2 bar when its warm, much higher when its cold. Is this OK?

[SECURITY]

sounds about right.

2bar at idle, around 4 bar when cruising and 6+bar when higher up in the rev range.

Excellent - thanks for that
