New age uprated fuel rails
 

Currently running 400+ on my 05 sti and I'm now considering of the above. My question is will they increase power or is it just a precaution on running high power.??? Also can anyone recommend me some with full fitting kit etc
Thanks

Precaution to stop cylinder 3 I think running lean.

Not many 'kits' out there apart from Perrin. Better off with a good set of rails, and braided hoses with fittings for a custom setup. Don't forget the fpr as well

So I need aftermarket fpr too?? Any one know where I can get it all from

Cheers mate ;-)

Why does cylinder 3 run lean? I thought it was because it's the last to revive fuel but it is the 2nd to last.

Is it just a safety thing??

Or is it due to the added heat from the turbo?
