I figure one of my next steps is to replace or mod my ecu, but I am now stuck on what to do to it, which brand to use, etc. I have done a DC Sports 4-1 header, DC Sports catback, AEM V2 cold air intake, Unorthodox pulleys, I have increased power and torque with these but feel I can still get more out of what I have. Future plans are 70mm throttle body, stage 2 cam, eventually a turbo, but that may be a year or two down the road. Any sugeestions would be helpful.

 

Sorry, I forgot, it is an 05 civic ex coupe, manual transmission.

 

first, your throwing $ away with a stage 2 na that would not work with the turbo, so dont bother.. does that tranny have lsd? it would improve your traction, or thin head gasket, inexpensive and not overly difficult buit will raise your compression a little... but i dont know if the gasket would be good or bad come turbo-time...

 

get an apexi vafc2.

 

Doesn't a thin head gasket throw off your timing? You also have to tighten up your belt to right? Is is good to advance the timing in a 2000 SI and how much?

 

why are you wanting to advance your timing? if you are using higher octane you should advance your timingto use the slower burning fuel, i think like 2 degree's. yes, the gasket does put your cam/crank timing out of sync, slightly... thats why one of my neext installs will be adjustable cam gears. (but for now i have the heads off again, taking to machine shop to install all my skunk2 parts)
