318 TBI Performance

New to the Forum...

I have an '88 D100 with the dreaded smogged 318 with TBI. 150 HP is just not acceptable. What can be done to this motor to get reasonable hp gains without going through the headache of a carb or engine swap? Cam? Port the heads? Valves? Etc...

I've searched all over looking for ways to do this and found some comments saying that the TBI 318 doesn't support mods and some saying to swap in a 360 TBI system.

Not much can be done really.
You might try removing as much smog stuff you can and see where that gets you.

I have a smogged '90 TBI. Basically what Dodgedude94 said, just try to take off as much smog gear as you can without screwing over the computer ;P

There are just so many hoses and vacuums on that thing that it's beyond ridiculous. I tried getting rid of the MAF, but that didn't really go so well for me. Just try different combos is all I can say, see what doesn't affect the performance too much if it doesn't work/isn't there.

So, I'm finally ready to pull off the smog equipment. Are there any good write-ups on what has worked best?
