Hello again, been a while since ive been on here, so id thought id share some updates on my Leon.

I bought my Leon about 2 years ago, totally standard, sorted out the usual issues and started to play, had it mapped at Rtech to 250bhp/290lbft with a stock K03s and all the usual stage 2 stuff, was quite happy with it for about 12 months, then got a bit bored with it, so wanted a bigger turbo and ended up going for a K04-064 from a 2.0 TFSI engine

along with the turbo i fitted a set of DM forged rods, full Supertech valvetrain, Bosch 550cc injectors and a general replacement of worn out parts, i changed the the core of the turbo for a BBT anti surge core also, everything on the car has been done by myself apart from the mapping

it was mapped at rtech again a few months ago and it made 340bhp/340lbft at 20psi, it could of gone more but it was running out of fuel so was capped, if i fit a higher flow fuel pump it will probably push 360, but tbh, its fine the way it is.

anyway, enough waffling, here are a few pictures(hopefully)
big load of parts to fit

standard 2.0 TFSI discharge pipe needs to be used as space is tight on the os chassis rail

By the way, are you done with the build? what other mods you have for it?

Really nice, I've incredible respect for people who take on big projects like this, especially as the car was actually running before you started! (as opposed to some barn-find restoration thing)
