Ok, so my mechanic tells me I should be on the lookout for a replacement for my K04s which is letting a bit of oil through, and I've stumbled upon this website:
Hybrid Turbo Upgrade VAG 1.8T 225BHP Stage1 - FR&R Tuning| MAHA Dyno Rolling Road Tuning| Stage 1, 2 & 3 Engine Performance Upgrades - (Powered by CubeCart)
which looks to me like an upgraded K04? Is that right? Should be a straight swap job?
So this website says:
Stage 1 - good for 260-280bhp
Stage 2 - good for 280-300bhp
Stage 3 - good for 320-330bhp
Stage 4 - good for 340-360bhp
So if I were to for instance need a new turbo tomorrow, and then go and purchase maybe a stage 2 turbo, and then bolt her on. What would I expect if no other mods were made? Would I blow my engine to pieces, or would it be strangulated by poor air flow in/out etc. Ill effects of this would be?
Only reason I ask is if im on the lookout for a new turbo, something uprated might be quite nice, but I really am an engine novice so I'd like it to be a straight swap etc , and if this requires strengthened engine internals, I'd probably not bother. All the nice upgrades will come in time (and money) and I think a nice round 300bhp is the long term goal.
Any help/thoughts/advice on this much apprieciated. Cheers
