354bhp e6 what's the next limiting factor for more power?

I ran 1.6 bar with similar mods to yours and after around 5000 miles fried my piston rings and suffered head gasket creep. Like previous posts have stated it is all down to each individual engine but before you push it any further I'd change your rods and pistons if you can afford it as it's far cheaper than a total strip. After that slap a 9 turbo on with the 20G billet wheel, I have done this and get 440bhp at 1.6 bar.

Yer I'm still undecided on how far I'm going with this car as I wouldn't mind a white 7 do i do pistons/rods or a full on 2.4 Stroker and transfer the engine into the 7 when the time comes. I originally wanted a 80 series but I want abit more scope for power so may go for a gt/gtx30 make my own exhaust mani and vband the downpipe etc. With being able to make all the fabricated parts it would seem silly not to go bigger as itl only cost me turbo,lines and injectors

Seems you've got your head screwed on fella, good luck with whatever choices you make.
