all this talk about megasquirt this and 2270 that, i'm getting really sick of my stock 2.0. i've decided to set a realistic goal for myself and strive to reach it. i plan on doing a pretty much stock rebuild with my 2.0 with the following exceptions.
96mm p&c's more aggressive cam msefi some mild porting that's about it really. nothing fantastic. just rebuilt heads and engine with some minor changes. just wanted to get some opinions on what kind of power this setup might make. i'm keeping my heat exchangers unless i find some cheap ss ones. now i have to start slowly buying all the parts since i can't afford them all at once.

yes, you have it right. when we talk about "gears" we are really talking about "gearsets" (drive and driven). (except for 2nd, which in our cars, 2nd is part of the mainshaft and not as easy to change, and definitely not possible to 'flip.') go here: Charlie Davis' Gear Ratio Page it has all the possible ratios, their names, and their tooth counts. have a look at the current 3rd gear: in a 914.4, that's an 'N' gearset, 1,261:1 look at a 4's 5th: ZD, .7097:1 when you exchange the drive for the driven cogs, you get the inverse of that: 1.409:1 that's a lot shorter than the original 1.261:1 note that in some competition rules, you get charged a LOT of points for non-stock gear ratios... read your rulebook... |
