I want to improve my performance to my protégé but with out doing an engine swap or adding a turbo so what are my options
my ride is a 91 DX it's STOCK to the bone! and is an automatic

is there any performance parts for 1.8 sohc like: HEADERS,Performance MUFFLERS, and etc input please

 

Since You're DX I'll assume SOHC:

-2.25 Exhaust w/performance muffler. We're running a flowmaster series muffler. The only complete bolt on system is the pacesetter, but it's 2.5 and I head it sounds like ****.

- Cone filter adapter w/cone filter. I've found that complete open element w/no heat shield seems to work best. Other thoughts anyone?

- Timing Advancement Don't know much about this since I've never done it, but supposedly if you turn your distributor a few clicks you'll get better throttle response. You'll have to use premium fuel from now on.

- Upgraded Clutch . Get more friction out of your clutch.



I'll let someone else take it from there.
