Cool, get them to tell you the exact spec of the turbo too.

If it still doesn't boost next week give me a call and I'll have another look. The last time I saw it the waste gate wasn't working so we stopped looking for any further probs

When you get your turbo back, if it still doesn't work I'll lend you a boost leak tester.

A large boost leak will often make less noise than a small one. I had no boost once and it was a loose hose on the intercooler.

Rob,

Yeah they are going to tell me spec of turbo mate as im interested. if you could take a look that would be great you can pick your bits up then aswell cheers Rob. i do have a leak tester that i made to go on turbo i can hear i lititle leak somewhere but can't work out where. i put 10psi in an it slowly goes down to 0

Nope, not a boost leak then everything is pointing at it being turbo related.... as long as there are no collapsing hoses, exhaust leaks before the turbo etc?

s2erst

compression test done right this time an the readings are 190 190 190 190 please tell me thats good

GVK.

It's good compression (healthy engine), but whether too high for your intended spec I don't know.

Its a lot more promising than 250 psi, when you do compression checks a nice consisten result across all 4 pots is definitely good news

s2erst

well the first one was about 185 not much difference bit gutted if i cant get as close to the 400bhp i wanted

SiZT

Is this the part when we find the wastegate penny hasn't been welded up? Hope you have some luck with it mate

s2erst

its been welded up mate

Just got off phone to cr turbos they have told me turbo is not in bad nick just a little play in bearing so they are now putting a 360 thrust bearing in an they also told me that it is a real garrett not a fake lol. i asked them what turbo is rated to an was told it will take up to about 450/500bhp so happy about but still dont know why its not boosting. i asked them if they had any idea an the kiddy said he had same problem an it turned out to be the manifold where it wasnt air tight an mines not either an its only happen since fitting new turbo an manifold

A 500 hp turbo on a Zetec will start boosting very late.
High HP turbos take alot of air to start boosting.
Hondas rev to 8000+ rpm, zetec's do not.

s2erst

he said it will be ok on mine

Canada1

Just trying to help you out.
A 500 hp capable turbo will not be anywhere near full boost at 3000 rpm - compressor surge may also be an issue with a large turbo.

Good Luck!

s2erst

dont get me wrong mate im very greatful for the help. i spoke to the bloke i bought it off an he said it came on full boost at 3k so ill be happy with that

creator

As perry has said mate,this turbo will be nowhere near full boost by 3000rpm
Also with it been a journal bearing an not a roller bearing to.

If you're reving it up past 5k and it's not boosting then you need to be looking at the inlet and induction system. A bypassed and blanked off external wastegate should have that spooling if the turbo isn't too big for the engine. Either it's not spooling which means the problem is on the exhaust side, or it is spooling but the air it's producing is not getting to the inlet manifold, which means split pipes, intercooler etc...

s2erst

Right thanks to crazycage i have now got my car boosting i have taken intercooler off an piped turbo straight to throttle body so i think my intercooler is fucked. thank you everyone for helping out im very greatful

Bomber

Good news!

s2erst

About time i had some good news mate

Jamie_EscortSport

good to hear matey! can now enjoy it

s2erst

At last only been since Christmas that i haven't driven it

Canada1

Great to hear!

Fix that intercooler or get a different one.
Let us know how the boost situation is.
When does it make full boost?
Curious to know.

Cheers

s2erst

im going to get a new intercooler i think. i get my turbo back on monday so will let you know cheers

crazycage

glad you found the problem mate

s2erst
