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
i did unplug coil pack when i did it but if your saying it has to be warm an throttle open ill have to do it again lol. i dont have anyone that is clued up enough to look at it thats the problem

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.

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...

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
