My initial thoughts on this would be to make some clear (as to not detract significantly from the look of the car) body panels to improve aerodynamic efficiency... but I have a separate thread for that http://www.6gc.net/forums/index.php?showto...mp;#entry928769
I post here however to discuss engine mods. Any ideas or thoughts on this? I was thinking of maybe advancing the ignition timing a bit to burn hotter, increase hp and hopefully mpg, but idk. Does a good CAI help? or a larger O.D. exhaust? What have you guys done? --------------------  |

Anything that helps the car breathe better increases MPG. Turbos, intakes, larger exhaust, clean throttle bodies...
Iridium laser cut plugs are great too. Areodynamics is a waste of time for how little you'll gain in the end. Realistically, you'll gain more from just lightening the car. CF hoods, CF hatch, strip the interior... lol. -------------------- 1994 Toyota Celica GT-S 5S-FE 190k Miles. Project car 1992 Toyota Celica GT 5S-FE 170k Miles.

I don't know about you but i'm not very keen on gutting my car haha. I know that making these things breathe better produces power power power, but I guess I'm curious to know if anyone has tracked the mpg change after making those mods. Or at the very worst, if you have those mods, post your best mpg up here. I know mine at 100% bone stock with the exception of the wheels ( which are a mathematical OD match to stock tires) gets maybe 31.5 - 32 with 80% highway and 20% city if I stay WAY out of the gas. Normal driving at 50h/50c with the occasional lead foot puts me at 26.5 - 29.5 -------------------- |
