Can I place the stock 850 in the primary rail since I have the aftermarket 1600

top feed? On the Gothem dyno run 97% on the 550 and then the 1600.

Since I got can I use em?

yep you can. you have to add an oring to the 850's as they are a tad shorter than the 550's. the only concern is that the o ring can pop off and then you get a fuel leak (thats internal) and a big vacuum leak. if you assemble it carefully it should be fine though.



idle will be a tad rougher

what would be an injector I can go to fit properly and would I have to change the fuel rail ther too. I hope the power FC could adjust the rate and this is now a monsta street port that it goes to. Still an idle problem though? Thanks for your help.

you can send your primary injecotrs to RC to be made to flow more if worried about using secondaries in primary rail my milling off an 1/8in or double sealing them with an extra O-ring as Mike pointed out... just remember these injectors are still used when you send them out and get them back...

or i offer an upgraded primary rail at KGParts.com
