Where the heck is the frp in an 04 o-z lancer i want to replace it to get rid of flat spots (Bad between 1st and 2nd) and in prep for forced induction.

Sorry heres a pic of where it should be that works

its a returnless system so its actually in the same housing as the fuel pump...not exactly easy to just swap out. and you can't use a conventional afpr. you need to use a special design or swap in all the 02-03 return fuel system components.

So what I get from this is just run an extra fuel pump and that should kick in when needed. Via the new fmu

Can you just put in a higher output fuel pump to take care of the problem and run through the stock fpr?

A ha the notorious RRM flat spot from 1st to second.

I am not sure if you can use a fuel regulator as the Piggy is tuned for stock fuel psi.
Pm Boeturbolancer and see if they can adjust the map for you.

the flatspot isn't fuel related. there are 2 reasons for this.

the first reason is that the ignition timing is pulled from 3000-4000 rpm. if you were to graph it, it would look like a U between those rpm. this would contribute to power loss in that range. the 4000-5000 range have a slight dip also, but not as dramatic and more accepted since peak torque is in this range.

second reason is because if you shift at 6000 from 1st to second, second gear starts a little above 3000, causing you to start in the U area where there's a loss of power from timing pull. all lancers have this problem and you can't really do anything about it without an ignition controller or a longer 1st gear.

i remember in wadad's case, it's theorized that the RRM piggy with the RPW header caused a lean spot in this area also. none of us have any hard evidence, but i believe it to be the case. THEN it would be a fuel problem.

as for RRM coming out with a kit, it could probably be adapted from the ralliart turbo kit since they run a returnless system also.
