antil33t 90 Report post Posted January 4, 2010 When I did my engine swap, I removed my AC, made it a bit easier to get it in, and the AC pump was seized anyways. Now my whenever I drive at 100kph the heater goes cold is there any differences between AC and Non? do they have a more restrictive grill or something?

e30ftw 410 Report post Posted January 4, 2010 Haha. My e30 had AC that I removed all piping to the firewall etc, Made no difference from what I remember. 9 Months off the road actually. Epic. Quote Share this post Link to post Share on other sites
Forrest 35 Report post Posted January 4, 2010 I just removed all of mine, all the hoses, condensor etc all the extra shiz inside the heater box so it is now totally goneskies. I am expecting 500hp on the dyno next week. Quote Share this post Link to post Share on other sites
e30plz 1 Report post Posted January 4, 2010 Yeah removing it doesn't really make a noticeable difference. Nice to think it's making your E30 lighter though. Quote Share this post Link to post Share on other sites

e30ftw 410 Report post Posted January 4, 2010 You can actually think of it this way, Removing rotating mass off the crank (i.e shaving down the flywheel) all makes an improvement to engine response. Works front and rear of engine. But front doesn't have as much things to delete, Except power steering and A.C, I guess you could remove that pulley that runs the A/C and P/S belts off the front dampner, that would be another subtle reduction in rotating mass on the crank.. But it's F all so don't expect a miracle lol. Quote Share this post Link to post Share on other sites

Remove that too yo' cut the springs while your at it Quote Share this post Link to post Share on other sites
e30ftw 410 Report post Posted January 4, 2010 Um no. There is a second piece which only is needed for PS and A/C belts. If you have ever taken the front of an m20 apart you would know this. And the Alternator/ waterpump belt runs right off the crank wheel. Sorry bud. Quote Share this post Link to post Share on other sites
