There are many turbochargers availale but 7500rpm is too high for the stock valvetrain. 7200 is a safe limit. Here in Greece a very popular turbo upgrate for this engine is garrett gt3071 along with a FMIC 3" full exhaust and bigger injectors you will see 320ps+ without any problems.

Regarding cam timing, can I increase overlap from 3k RPM up to redline?

No. The only type of variable cam timing on the 1.8T is two position.

I suppose it could be called switchable cam timing. Do you have the lobe center angles for each position?

Man it sure gets expensive for more hp. That's going to have to be after I win the lottery.

Yes it's like that thats why almost all of us try to squise every last of horse power without throwing serius money, out of that small turbo and this small engine. Cheesy

Keeping my word, here are my bins, original read and latest tune. Tune is maxed boost, 4bar regulator, upped rev limit 500 RPM, .86 AFR when 80% to 100% throttle, timing advanced over stock at peak RPM but car still has zero individual cylinder retard on Mobile 94 octane.

All stock parts except for regulator. Logs and csv's are a few replys back.

Best Regards
