Not really. It was a old a motor when i got her, she wasnt in her prime (194k) cheap and easiest mods are-
-Advance the ignition timing (requires higher octane fuel)
-WAI or CAI (intake)
-Exhaust (no bigger than 2 inch on a n/a 1.6L)
-Header (obx has them on ebay, if you get lucky enough and find it, get a hotshot)
-Jwt aluminum flywheel (pricey like close to $400 bucks i think)
Little mods like a short shifter, polyurethane motor mounts, help alot too.
As far as short shifters go, i got a B&M its great i love it, some people like the "nismo" ebay ones, some dont.
polyurethane motor mounts, they only make them for the SR20DE (fwd) they fit, i had them on my 1.6L, search my old threads, its in there. Polyurethane motor mounts cause more engine vibration, but you'll like it. It reduces engine movement to almost zero.
Then more serious mods for the 1.6 are - ( i only call them serious cause they're over $500/each )
-Jwt ecu reflash (easy to install)
-jwt cams (S1 series i think?)
If your looking for a header, I bought a SS OBX one on eBay. I decided not to use it. It us BRAND new Uninstalled with gaskets. Ill sell it to you for cheaper than you can get on eBay. PM me if interested. Otherwise ill have it up on eBay shortly.
