is that turbo bellys setup?Ok so been busy on ebay and bought Millie some new parts.
New cam cover gasket.
Both coolant sensors.
A pack of gasket paper for my throttle body.
And of course the turbo which is a Garrett GT15 44S from a Vectra/Zafira 2.0DTI
Will be sorting a manifold asap.
This will be a time taken turbo build... I plan on keeping the car for a long time so there is no rush.
my main priority is chassis work and preparing the shell for more power.
This will be made harder by the fact that shes my daily, there is no spare car to drive while shes off the road so days off and afternoons will be when work is completed.
Nope bought online from a trusted breakers yard no play in shaft and end float has been measured.is that turbo bellys setup?
I got like 2mm float... Bam.. More float = moor funNope bought online from a trusted breakers yard no play in shaft and end float has been measured.
He didnt say how much float but said it was in good condition will measure end float as soon as it gets here.I got like 2mm float... Bam.. More float = moor fun

2mm is Bella bad lol. To be be honest you need some proper equipment to check it. Just check it side to side. Then in and out. Just be really careful. Don't bash it around. If it hardly move you are Quid's in. Mine never moved really.. Then I upped the boost and the shaft is un balance so now it's shagged.He didnt say how much float but said it was in good condition will measure end float as soon as it gets here.
Ahhh right gotcha...2mm is Bella bad lol. To be be honest you need some proper equipment to check it. Just check it side to side. Then in and out. Just be really careful. Don't bash it around.

I would also say that these rebuild kits are a bit silly? Surely the imbalance of he turbine causes the issues? Well contributes greatly. I think I am just going to buy a turbo from turbo technics.a fraction of a mm play is normal for journal turbo bearings cos they usually float on a film of pressurised oil.
but when clearances wear too much beyond that, say 2mm+ then it starts to have problem with losing oil pressure at the bearing, seal issues and accelerated wear. all leads to smoking exhaust.

At 120kRPM you'd be surprised how much even a mocroscopic amount of alteration makes. Also, the inner bearing races on a ball bearing turbo will not be balanced perfectly etcif ur just replacing seals and bearings, long as you mark the exact turbine/compressor/nut angle and align it on assembly, it'll be as balanced as it was beforehand (assuming it was).
if ur replacing any damaged rotating parts then they'll need rebalancing.
dunno what the labour cost is but if its more than the cost of a used turbo, I'd just buy a used turbo with good condition blades and rebuild it with the new bearing/seals if required.

Dem sounds like magicevery little helps.
aye they spin really fast
if only someone invents a high-temp levetating bearing to eliminate any oil feed & shaft friction.
then join the turbine, shaft & compressor non-mechanically through magnetic coupling (like some aquatic pumps) so no chance for any leakage but still able to transfers torque between the turbine/compressor.
pie in sky idea.

Just got a message saying turbo will be here tomo yay

Erm... when the wastegate is pushed closed and I put my finger over the other end and then release my finger the drop in pressure opens the wastegate...is it a +ve pressure WG or vacuum operated WG system? from a diesel or petrol engine?
wanna make sure the +ve compressor pressure feeding into the WG is trying to open the WG valve rather than closing it tighter.
Always full of ideas hey mate!Just keep holding it there.... job done.
Always full of ideas hey mate!
Houston we have a problem!Yep...it's a wonder that NASA haven't headhunted me for their "special" projects...
Or this if you drive a diesel :
So after cleaning up I decided to have a look at placement, christ its tight!
But think ive found a way it will work.
Only problem is radiator will need moving forward slightly.
And the dip stick is in the way of where my dump pipe would go.
Rather irritating.
You can see in this one the wastegate is resting on the radiator.
Think ill have to get the welder and see what kind of manifold design I can come up with.
Any advice always taken...
You legendyes i took the slam and grille off to show you in detail mate and try a bike pump on the w/g pipe
Yours looked like it was mounted high at jae mate any chance I can get a pic of your set up?Jesus that's loads of room what you talking about

sounds like a vacuum one mate, and there,s no pipe fitting on the alloy compressor housing eh, my 1st two tubby,s were vacuum ones tom, i just fitted a + pressure actuator and repositioned the arm (i had to move the arm on most of mine, after clocking the turbo anyway)You legend
Not got a bike pump but ive got a good set of lungs...
With no pressure wastegate is and stays open if I suck in on the w/g pipe the w/g closes.
