Is this yours for sale or just your new kit?
Stock internals are okay with big turbo stage 3 aren't they? It's only stage 4 which requires forged block?
Its the kit ive had on for awhile now mate just got some better pics of the full kit
Stage3/4 can be run on the stock motor just depends on what boost etc how safe its going to be personally i wouldnt run 480-500hp on a standard engine but i do drive my car hard and it will see track, what hp is safe on the stock engine i dont know tsr are testing the kit with stage 4 on a standard cupra k04 engine at the moment
