Converting to parallel twins
I am a new owner of a montego blue fd and i am absolutly thrilled with it! I am performing some simple mods such as a RE-Amemeya intake, 3" ss downpipe and midpipe, Racing Beat dual tip exhaust, Apexi Power FC and an Exedy clutch. So far, pretty basic stuff. This winter I will have a chance to do some real power mods but i want to keep the costs down. I heard that you can run higher boost if you conver the turbos to parallel and run 4- 850cc injectors. Any truth to this??

You'll need an upgraded fuel system to run higher levels of boost (above 13-14 psi), no matter what turbos you have.
You do not have to go non-sequential to run higher levels of boost, but the turbos will probably last longer, due to the primary running much less often and the secondary not having to be pre-surged up into operational speed.

So if i were to run around 15psi, the 550cc injectors plus a set of 1000cc's would be alright if i converted the turbos to parallel? Obviously a bigger secondary rail and fpr and pump would be included.

that should work. the pfc will of course need to be adjusted for the injectors, and if you throw in an IC and tune it, youll make some decent power. but you don't really need to go non-seq. unless you gut the sequential actuators and such out of the turbo manifold, you wont make any extra power, and you will want a catless exhaust for a decent spool rpm with non-seq. if the turbos are transitioning properly, you might as well stay seq.
you would probably just want to go right to some 1200's instead of 1000's though.

so i think i will stay sequential and kick the boost up a little to maybe, 15psi. get a set of 1200's and tune the pfc to accomodate the whole setup. I do have a catless exhaust, 3" ss turbo back to a dual tip racing beat so i should be alright there...thanks for the advice.
