You finally managed to shoehorn it in then. I take it that means the Octy is back on the road then? 165mph - you bad man!

Nice, that must surprise the hell out of people!

Was it a tricky install to do? Look forward to some pictures.

Cheers, Ed

That dodgy boost guage of yours again James.

Have you clamped the map. How do you stop it chucking overboost codes? [:D]

I thinks it's the most popular conversion choice in the US at the moment.

For those of us who don't know, how does it compare to the IHI [?]

Ok, well its an ATP turbo though. I take it you guys have just made up your own mannifold for it then. What sort of price will the kit be as I'm evaluating larger turbo solutions at the minute.

... s3 pisons 20mm rp ...

Oh yeah, forgot to ask, surely not 34psi on standard S3 pistons?! Thats 2.34bar!!! Was that just bench testing then? I would have thought you would have blown the cylinder head off at that boost!
