Fuel economy is… well, not very for people on budget. Also the engine cut the power when the engine is still gaining power and have a worrisome reliability.
You should take a different design path for the engines internals or change the engine “behaviour” in order to have the power at eariler RPM to avoid an early engine brokedown.

Try to fix up the issues with engine [/quote]

Okay, now you’ve bumped up several quality sliders. The reliability is better but now:
this is clearly no longer a poor man’s engine, with a production schedule of 468PU.
the power curve is still a problem. That massive swell of torque just at the top end makes for the worst if all world’s: bad drivability, very narrow power band, and the other preexisting issue, bad economy.
To solve all your problems, I’d back off on the turbo. Make both sides quite a bit smaller. Make sure it doesn’t spool so late. Reduce the Max boost, so you don’t have to toss up between your parts hitting a torque or rpm limit or abuse quality to get a decent reliability. You might lose a bit of Max power but your car will end up overall faster, lighter, more reliavile, cheaper and more economical for it.

Well now you have knock, but your power band, cost and economy are all getting better, try adding 1 tick to your cam profile or dropping the turbo compressor by a tick.
Also if you are using a huge intercooler drop it to a large.
