I was just wondering that with the hp gains from bolting a turbo (intercooled or not) would put a major strain on the chasis and exactly what kind of rigidity issues would need to be addressed to prevent structural integrity issues. I'm looking at getting a turbo for my Lancer in the next year or so, and I want to get an idea of what all I need to do before I start heading down the forced induction path.

 

There really aren't any issues with the structural integrity of the car until you start making alot more power, then subframe connectors and a roll cage would be a starting point, the drivetrain would be of more concern than anything else, as a side note intercooling a turbo motor is advised to prevent engine knock which can kill a motor.

 

A couple people running as much as 7psi on non intercooled T-28 setups are still running extremely cool. I'm wondering how summer heat will effect this, but I can't forsee there being any problems unless they up the boost a bit more. The T-28's seem pretty efficient at the boost levels between 5-7psi.

EDIT: For some reason I edited out any relevant content that may have been in my original post. Oh well.

 

There should be no chassis strain. The lancer chassis was built a lot better than the mirage.

Besides, no street-driven 4 banger will have tremendious TQ like a big block V8.

As for heat, if you don't live in TX or AZ, you should be fine. Now, if it gets to +105 degree w/o IC, I don't know.
