hybrids ??

[eyefi]

is it best to hybridise uk or jap turbos, or doesnt it matter?

[Terry S]

doesn't really matter. What ever you have as stock wil be a good base.

[eyefi]

is the uk wastegate larger as standard?

[Terry S]

AFAIK it's the same size as the J spec. It's really not worth changing either way.

Hmmm I was under the impression that the UK turbo's had different wastegates and this is why they don't suffer boost creep like the j-specs - when de-catted.

Also don't the UK's require a UK manifold.

[Terry S]

I know the manifold is different that's why I said it wasn't worth the bother. Still not sure about the WG though. I'll check, although I would always recommend that a bigger wastegate is machined in no matter.

I thought boost creep was prevented by the EGR system, hence the need for boost controllers to raise boost on UK specs. For Jap 1.5 bar is for free.:eek:

[eyefi]

how much can the wastegate be enlarged by? would this also include fitting a new valve (correct term??) on the wastegate?

excuse my ignorance, im not very familiar with the stock turbos, but would it be possible (or worthwhile) fitting an external wastegate if u had a custom exhaust manifold made?
