1990 Pickup: too old for upgrade?
Hi,
So I bought the 1990 pickup with 275,000 kms (170,000 mi)
First Question: Can I "upgrade" the breathing (air intake, maybe exhaust) on this old engine without the extra hp blowing it up?
I'm looking for a few more ponies without compromising my fuel economy, or costing too much.
