Sure it can do it, but it's safer to not. Throwing a rod at 7k is no fun. replacing a shattered piston skirt at 7k is not fun either.

Oh, and please show me someone with shattered pistons that wasnt melted from a bad tune or done in by a broken timing belt

RE: Which setup does it give more stress on engine
high rev's make more stress. with the question this thread was about, the bigger turbo would be making peak boost at high rpm. maybe no one here has done it to our cars. this thread was a general idea. i was simply saying what is generally true about engines. high rpm's can cause a multitude of problems.
I explained my reasoning behind everything i said. argue against that. engines wear, wearing creates larger tolerances. at high rpm's, larger tolerances ca be detrimental to an engine.
Besides, our engines weren't designed for super high RPM's. there is a reason the hondas spin to 8-9k without problem. their meant for it.

if you believe this, dont ever go with anything above a gt28 family turbo.

The engine will wear regaurdless of what you do, but not excessivly like you are claiming. Running the 1.8t to 6-7k on stock parts is like chipping the stock turbo. Sure, it seems like you could hurt it, but your not.

Your the ONLY person saying ours arent. That is either ignorant or nieve, ill let you pick what you want me to call you. The only reason the stock rev limit is set to 6800rpms is because there isnt any power there or above that. Hell, they could of set the limit to 6200rpms and thats still more than needed. Just because there is a limit doesnt mean the engine isnt capable of more. There are 100's of people running 7200-7500rpm limits on their cars now. All you have to do is 1) get a turbo to warrent it and 2) ask the tuner toset it there.Hell, there are even people with 8k limits and still on a completely stock head. And before you ask, yes, they do take it there and often.

Sure, it seems like you could hurt it, but your not. faster parts wear more. you simply cant argue that. im sure our engines will last a while runnign 6-7k on stock parts. but going above 7k makes lots of wear, expecially at higher boost. i didnt say your engine would blow up!!!!

So im ignorant or nieve... our cars are tuned for lower RPM. the valves, heads, valve springs, and cams are allll meant for that range! they arnt designed for those high RPM's. sure, they can go there, but they wont perform their best!

Listen: this arguing is getting pointless. This thread was made about a general idea. thats what my answers were for. i didnt say that everything would blowup like a hand grenade if you went too high! He asked which would wear more. put more stress. BOTH DO IT. BOTH STRESS IN DIFFERENT WAYS. get over it. i have not once come here and said your ideas are wrong. i havent called you ignorant, nor have i taken what you have said and made it an extreme and said you dont know anything. cmon now. you are talking to me like i have no engine experience, and frankly, thats disrespectful. im playing nice, you do the same.
