glcoupeguy Posted October 19, 2009 Share Posted October 19, 2009 sorry about making two threads but this seemed best as its a separate topic. i want to advance timing on my EA82. i have NGK platinum plugs with a blaster coil, cold air intake and 2.25 catback exhaust. how far can i safely go?

torxxx Posted October 19, 2009 Share Posted October 19, 2009 none of that really affects timing. Higher octane fuel would allow slightly higher timing. So would removal of any/all carbon on the intake/heads. You wont be gaining really anything by just turning your timing up. You would need longer duration cams (valve timing) to gain more power if any. EA82 is a very weak engine power wise with not many options to get them over 100 hp. and as for advancing your ignition timing, turn it up until it pings on acceleration. There is no "set" number for these engines. each one is different. my carb'd EA82, if I get anywhere over 10 it pings like crazy. SPFI runs at 20 BTDC so you might be able to hit 24 or so but they also are prone to detonation. Just remember detonation = holes in pistons Link to comment Share on other sites More sharing options...
bheinen74 Posted October 19, 2009 Share Posted October 19, 2009 Are you using premium gas at all fill ups? If not, just doing that wll do more than increasing timing, which should be set at factory specs, +/- 2 to be safe. Most people want more performance, but arent willing to pay the price of premium gas. higher octane does not detonate as easliy, and is safer for your engine. Use premium if you don't Link to comment Share on other sites More sharing options...
glcoupeguy Posted October 19, 2009 Author Share Posted October 19, 2009 (edited) the car hasnt seen anything lower than 92octane in months, the oil is always pretty fresh, its been seafoamed twice. im thinking every pony counts because the car is so light but im running out of ideas. i do have an EJ20 for the car but that probably isnt going in till spring (the car is mostly a toy to me so im not extremely worried about ****ing it up + i have another engine sitting around) Edited October 19, 2009 by glcoupeguy Link to comment Share on other sites More sharing options...
torxxx Posted October 20, 2009 Share Posted October 20, 2009 turning your timing up is going to give you about 0.2 HP... pointless imo I don't think anyone's gotten the N/A EA82 much over 110 HP. maybe 120 hp but you are putting tons of money into an engine that was never designed or capable of making that much power. Put a EJ22 in it and be done with it If you wanted to make the car fun, pull out a front CV axle, take it apart so you just have the outer DOJ (goes pretty easily, take the boot off the big side, take the snap ring out around the big cup and pull) stuff the DOJ back through the axle. Now your car is RWD. take the rear diff out and weld the hell out of it. Now you just made a fun EA82 car. Link to comment Share on other sites More sharing options...
GeneralDisorder Posted October 20, 2009 Share Posted October 20, 2009 Yep - advancing the timing isn't going to do squat for you. And you should be using the LOWEST octane fuel that the engine will handle without pinging. You are wasting money and losing performance by buying high octane fuel that your engine doesn't need. 92+ is for Subaru's with Turbo's.
