Safe limit to push a K03 GTi

[xxx_mojo_xxx]

What's the safe limit to push a K03 engine before you're asking for trouble. 

Put in another way when can you start expecting to blow up the engine or chewing up a DSG gearbox?

This is assuming none of the engine components have been upgraded (apart from the DV valve).

i dont think there is a limit, i think you just upgade to KO4 when you run out of ponys.

Are you suggesting you simply replace the turbo with a K04 and continue to push more bhp out?

Surely things like piston rods, valves, cams, etc. have an upper threshold after which you are seriously degrading the lifespan of the engine or running the risk of blowing it up?

^^ not really sure, but i think jonny is running about 400bhp on standard internals but big turbo.

Wow, and is that his daily run about too?

Yes but on standard ED30 internals.

I thought so...on a standard GTi I think the limit would be significantly lower.

Plus, a DSG gearbox would probably be beyond it's limit at 400 bhp.

So, coming back to my original question - anyone got an idea?

didnt know there was mucho difference, also jonny is dsg i think.

How far beyond 300bhp do you want to go?

The difference is not as much as people think, apart from the low CR.. 10.1:1 compared to 9.8:1 of the ED30 the rods are basically the same apart from a larger pin.. Thats the only thing that would affect the bottom ends strength..

I think generally people are a little too scared of 'pushing' the limits.. K04 on a 2.0T FSI is not a problem, its really not..

I know im running an ED30 motor, but im running 22psi on a 3076R.. Thats be proven to be over 400WHP so high 400's crank.. The same as been achieved on AXX motors without problems IF the tune is right.. You could throw a rod on a K03 turbo if your tune is sh*tty, thats a fact..

Also there is this fear surrounding the DSG box, show me one that has broken (anywhere in the world) due to too much power or torque..

To answer your question, if your running W/M injection and every single bolt on going 300hp is achievable on a K03 turbo, any more than that and your kidding yourself..

^^bacillus is KO3 and running 300 on a DD RR, he is even on standard intake!
