That's the plan Scarr, we're making 348bhp from just 18psi at the moment, with very little heat, fantastic spool, and it drives like a factory car, because it IS a factory stock turbo.
A kit is currently being developed and thoroughly tested, and once it's all finalised and tweaked, it'll be put into production and sold as an alternative to the current line of ko4-023 hybrids.
For those wanting slightly less ambitious power, the kit will also allow fitment of a tfsi ko3 turbo, which should see power around 280-300bhp when mapped to suit, and would also allow a direct swap out to the 350+ capable ko4 at a later date!
