Also ASP will work too I've heard. They make them too.

Heads swap to 3x00 stuff yes, but that will require chaning power steering pump and other stuff. Just swap a full 3400 in if you are going that route :P

The 3.1mpfi made lots of torque down low due to the skinny long runners. They drop in power in the upper RPMs due to the intake manifolds crappy design though.

TB is 52mm but going bigger won't really help with the old school heads and intakes.

the way i see it, bolting on 3100 heads and intakes will just get me to where my malibu is now... I'd rather just work on the stock manifolds to gettem flowing a little better.
im not sold on UDP for a 93 with an older alternator, water pump, etc... but the exhaust and intake definately need some upgrading.

im wondering with the OBD1 system it has if it's easier to trick the computer to squeeze out a little more fuel... i dont know, i havent messed with an older 3.1 in quite a while, and i dont even have the car yet.... stil sitting in my buddies driveway... dead ass battery, first thing i have to buy. I probably need two rear calipers, fuel line, and since it's been sitting so long, the wheel bearings may have developed flat spots....lol, but it'll be fun getting her back up and running.... i love the steering wheel in this car... it's so old school lookin!

You'll not get far with the stock intake. Even porting it won't get it near the size of the large 3x00 stuff, and also it has un-even runners, and bends that you can't get rid of. Personally I'd just drive it and mod the malibu.
