Yeah, power without control is nothing. Yet power is addictive. Original injectors can take up to about 15psi but that's pushing it to the limit of its duty cycle. But that doesn't mean we can just whack 15 pounds and hope the horses will start pulling from the wheels.
You need bigger pumps and fuel pressure, lower temps, turbo type... etc. And when you have that you might start having erratic idle... and you start getting more stuff... etc and suddenly with that power, your stock clutch will start yelling to you it's quitting... and that's where you need one strong enough to hold it all together.
and ... man... pocket will start shrinking right when you hit the 190hp mark. Believe me, I've been through quite a number of turbo conversions. Depends on how loaded you are cos with a tight budget, you can still stretch the hell out of it but it might still tear up.
If you have friends who've done it, follow their footsteps and learn from their mistakes. You can save a lot there.
I wish you well on your endeavors. Good luck.
