Also, keep in mind, these engines stop making power around 5500 to 6000rpm range.  Many many members in the past have come across this even on heavily modified cars.

Dang, so no hope of spinning these up into 9-10 k honda territory?

Nope. Lol.... well maybe for a second.... hahaha. JK. They are what they are.... in reality, half of a small block V8. They
run, and operate as such too. But what everyone here has said is true. You can have a surprisingly quick car on an upgraded Mitsubishi turbo, with just a few supporting mods.

9-10k comment probably said in jest. Peak hp means nothing. Hi revs mean nothing ('cept a quick death)
Ride in a full street 9sec GN, redline 5600rpm
Similarly a G54 makes enough midrange tq, plus has the lungs to spin up a 'decent sized' turbo
A healthy motor + good combination, once tuned.... find traction n go have some fun

Great info in this short thread.  My goals and questions are similar to yours Alrightythen. How much of a difference would Stainless Steel valves, Caravan intake and Low Impedance injectors make for flow and results on the factory TBI set up. I'm sure a ported throttle body would would be a big help also to get more air in since we are trying to get more out.

Caravan intake to me is not worth the effort.

I've read 20 to 30 up, is that too optimistic even with other flow modification?

I run all of that except the low impedance injectors. Ported to 52mm intake/mixer/TB, SS oversized valves, HD springs, 2.25 intercooler pipes and a big intercooler, 3" exhaust, Super16g/TD06, Profec-B. The car is fun at 20psi, but still drives like a Starion and the more mods, the more fussy it gets about how it wants to be driven and the rpm range that it's happy in shrinks.

The last thing I want is a car that is too temperamental to enjoy driving. Sounds like you have a good setup.
