is your valve cover PCV port just open to atmosphere on both side? That seems like a fire just waiting to happen to me.
You’re probably getting some wastegate flex with that mounting solution. My car feels very lazy on just wastegate spring. It’s only like 6psi and I don’t see that until 4K rpm or so. Get some sort of WG control on the car. Also that crunched downpipe isn’t doing you any favors.
The 1.6 has a great oil feed on the block you can use and right next to it is a water feed, which looks like you choose not to even water cool the turbo. Kinda questionable but I’ve seen people do that after cracking a feed line on track.

And/or some sort of boost control as others have mentioned.

Do a test, unhook the WG signal line and see if spool improves. Be careful as there will be no boost control but this will tell you if your losing spool through the wg cracking open early.

Anybody have any logs to post up with their respective setup? have always been curious about 1.6 spool with different manifolds and exhausts despite everybody sh!tting on it for being inferior to the 1.8.
I'd really like to see a journal bearing 2560 vs a BB 2560 as well.
next time i have my car out i'll try to grab a 4th gear log. i've always kept my eye on the spool data thread but it's obviously very 1.8 dominated.
