I'm pretty sure the biggest restrictions of the 5s are it's availabilty to breathe. That's probably why a turbo adds so much horsepower.
When my car was NA, I never put a header or exhaust on, so I don't really know how much horsepower they actually give. But, from what I've read, adding headers helps the top end out alot, which is where this engine runs out of steam. so, though it may not increase peak horsepower much, it should help out the powerband. The 5s also runs pretty rich at full throttle too. So, I'm sure a piggy back to lean out the A/F under WOT would help. --------------------  94 GT - Sold -------- 69 Pontiac Lemans - Sold 88 Alltrac - Sold ---- 04 WRX - Sold 00 GT-S - Sold ------ 91 Miata - project/drift car 95 GT - Sold -------- 96 GT - New Daily Drive |
