Ratty2Austin Posted November 14, 2005 Share Posted November 14, 2005 welcome to the board! a good suggestion, from my experience- start with general clean up, tune up (plugs, wires, cap+rotor, disty advance check/adjustment w/timing light, oil changes (all fluids+filters, dont forget the fuel filter near the tank, not just the one up front) and then some fuel system cleaner (not STP brand) and just a tip, many of us have discovered.. that OEM parts work the best (dont go cheap, its not worth it) especially when it comes to the plugs+wires, ect... synthetic oil will work well, by reducing friction in the engine- also reducing the running temp. but it may cause it to leak- so only use it after a reseal! when you drive the car, it helps to bring it close to redline occationally when driving, this will cause the fuel/air/exhaust to flow faster thru the motor, and "clean out" some of the carbon and crud buildup on the valves, ect.. hope some of this may help.. then the big mods come later, (or sooner, if you want to skip the above mentioned and go right for the "EJ22 swap, see the conversion forum for that) Quote Link to comment Share on other sites More sharing options...
Subarian Posted November 15, 2005 Share Posted November 15, 2005 The age-old questions are "how fast do you want to go" and "how much do you want to spend?":grin: Quote Link to comment Share on other sites More sharing options...
northguy Posted November 15, 2005 Share Posted November 15, 2005 Welcome to the board. If you want power, look at a transplant. If you're happy with the power plant you have, follow Austin's sage advise. He's been around ea81's enough to steer you in the right direction. Also, look at Mcbrat's homepage. You'll be impressed.

Phizinza Posted November 15, 2005 Share Posted November 15, 2005 The age-old questions are "how fast do you want to go" and "how much do you want to spend?":grin: For me it isn't "how fast do I want to go" its "how quick do I want to get to that speed" Think about it, whats more fun, driving 120mph, or getting to 60mph in 6 seconds? I've seen a few subies with super charges. Well, I've seen one in person, and I've heard of another. the one a saw was in a buggy with a EA82t (with out the turbo, and the fuel injector spots welded up.) I can imagin that would be fun. So, I'm not sure about all of you, but acceleration is my drug. I don't suggest trying to mod out the EA81, its just not worth the money EJ engines are the go. All you need is an adapter plate and it fits right on the older style gearboxes. The hard thing for some people is the wiring loom. But theres so much writin up about the swap on this forum. And if you have any problems, just post a msg! Quote Link to comment Share on other sites More sharing options...
Jerry DeMoss Posted November 15, 2005 Share Posted November 15, 2005 I for one love the ea81 engine.You can get pretty good power out of them for what they are but they won't compare with a ej22(legacy motor).A good place to start is put a weber carb on it.Larger exhaust.
