I pretty much know how a fc3s is modded for the power a person wants to reach here in north america which is the usual haltech and 1600 secondaries(low impedence) with the fuel rail and other things here n there.Now in Japan there running 1000cc secondaries along with a high flowing pump and a pfc for the most part. how did they get the 1000cc as the secondaries?i also seen some were using 850cc high impedence for secondary injectors.I seen on border racing they make some kinda kit to adapt the 850cc high impedence(not sure if top or side feed)+fuel rail for the 850cc,is this what they use?souls car even had 4 1000 injectors,but never got any info on what fuel rail he was using..



thanks..just curious

rc engineeering can make a 550cc injector and bore it out to 1000cc. blitz also sells brand new 1000cc injectors that are drop in. they are VERY expensive though......

the 850's that border sells i think are fd injectors, they make an adaptor to fit the whole fd rail in there

Thanks for the info,smetimes i get bored cuz i read the same mods for every car in north america..just wanted to know what rest of the world was doing..



thanks..

Do the RC injectors still work on the stock rail?I was thinking of using my 720's as primary's and bore out the secondary's to 860's.



Luis

Yes if u bore out a injector it will still work on the stock rail.

whats the advantage performance wise between top feed and side feed injectors..



thanks

probably a custom rail...
