so i wanted a poor man's mid engine. so here it is.
i spared expenses on every corner

update. fixed fuel economy. but reduced power. increased reliability

so basicly how it goes. fix one thing, another one suffers

fuel mixure and compression is on minimum
0-100 4.2 seconds but hey! what do you except from a "budget car"

Why don't you post that here: viewforum.php?f=35

Instead of filling general chat with off-topic threads.

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.

It's like Peugeot 607 in hands of typical polish; cheap to buy, but it's pain to service.
Try to fix up the issues with engine

better ?

Okay, now you've bumped up several quality sliders. The reliability is better but now:

1) this is clearly no longer a poor man's engine, with a production schedule of 468PU.

2) 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.

Sweet baby Jesus why are you using single point fuel injection. Put multipoint in there for instant gains.

Very nice torque curve.

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.
