danutt 4 Report post Posted March 6, 2006 got a 318i its auto but im keepin it ive got a pod filter in the bumper as a cold air intake better exhaust which is less restrictive im looking to do sum more to it just you know for a lil more byte would changing the intake to a short ram with a heat shield be better? headers or cam gear? does advanced timing help that much or should i retard it for torque down low? considering taking the cat out this week would that help?sound nice?too loud? WOF? or is there a power gain of sum sort sum help or answers are gladly appreciated thanx :mosh: Quote Share this post Link to post Share on other sites
E30stz 0 Report post Posted March 6, 2006 A manual 318 as oppose to an Auto 318 produces much much better performance as far as I've seen. Headers and cam gear would be rather pointless I believe as the cost involved doesnt justify the output you'd be getting. Quote Share this post Link to post Share on other sites
smithy 0 Report post Posted March 6, 2006 a 318 =105hp if u get a 2.5 straght six 325i=170hp not much point in spending alot of money on 318 but if u put a turbo on and did some internal work port and pollish ect u might get some HP but still might be less than the 325i and also get a manual Quote Share this post Link to post Share on other sites

*sic 1 Report post Posted March 6, 2006 cai in bumper has a chance of getting wet now its winter, short ram and sheild would be the win. headers first. cat out! Quote Share this post Link to post Share on other sites

kerrynzl 3 Report post Posted March 17, 2006 Advancing the Cam improves low down torque[bMW Vanos retards to help starting,then advances for low RPM,then retards at about 3000 rpm] short intake runners & exhaust primaries are for High Rpm [high rpm=less time between pulses=short runners] most hp gains with headers are through open exhaust [they usually have different duration on the exhaust cam lobes to help scavenging] Get a bigger engine, its pushing the same weight car so it shouldn't use much more gas than standard.

E30stz 0 Report post Posted March 17, 2006 (edited) what do you want .. seriously ? a fast auto ? quick off the line ? something that sounds good ? something that can overtake ? something you can have fun in ? please specify. If your wanting to pull out more performance .. your not going to be able to feel much with having a 318 auto engine. If you answered yes to many of those .. your probably best finding a Auto 325 Edited March 17, 2006 by E30stz Quote Share this post Link to post Share on other sites
