Scott in Bellingham Posted February 2, 2007 Share Posted February 2, 2007 ok Ive read all the jokes about how this engine is helplessly flawed with siamesed ports and all , but I would like to know what can be done to get more, even if its a little, lowend torque out of the EA82 engine, I have a 87 SPFI EA82 which I offroad and without low gears it needs some more lowend grunt, also I am aware that a EJ is more superior so lets not go there Thank You SJR Link to comment Share on other sites More sharing options...
mcbrat Posted February 2, 2007 Share Posted February 2, 2007 not sure how much of this can carry over to the SPFI EA82 since I'm a carb guy, but this is what I have on my Brat w/ea81 and weber... torque grind Delta CAM recurved disty from RooBuilders (out of business now) Excel Super Coil (big squareblock kind) MSD6A Ignition (multi-spark) Exhaust properly sized for torque and not HP Link to comment Share on other sites More sharing options...

Hodaka Rider Posted February 2, 2007 Share Posted February 2, 2007 FI is better overall for offroad. Try a heavier flywheel. This won't give you more torque, but will give the engine more inertia, so it will crawl a bit better and stall less. Link to comment Share on other sites More sharing options...
GeneralDisorder Posted February 2, 2007 Share Posted February 2, 2007 Cams, and MegaSquirt will get you what you need. MegaSquirt would also allow you to fit a larger throttle body for more low-end. As a side benefit, with MS, you could drop in an EJ22 (or a JDM DOHC EJ20) later on with minimal wiring effort. GD Link to comment Share on other sites More sharing options...
[HTi]Savage Posted February 2, 2007 Share Posted February 2, 2007 Exhust would make a huge difference here. Get rid or the cat and stock muff. stick with stock exhust cross over and run like 2 1/4 or 2 1/2 pipe with a cherry bomb or somthing w low restriction.
