How will this effect the car with no mods? Im doing this first since I have leaky injectors and it makes daily driving near impossible since it floods so badly. Will having the 4x720's make it run rich or will it compensate enough to keep it at a reasonable a/f? I plan on very soon getting exhaust, followed by BNR stage 3 and some other junk. Thanks for the help

 

A car with no mods would mean you are running stock injectors, so the 1.8 would not be a good choice as it requires 720x4.

Now if you have the 720x4 injectors, then you should be fine.

 

well of course Ill have the 4x 720's, just wasnt sure if having the stock restrictive exhaust and all of that would cause problems. Wasnt sure if the 1.8 would compensate low enough on the larger injectors to keep it from running pig rich.

 

It's designed to keep the target AFRs the same as the stock motor. You'll be fine.

 

Has anyone installed a RTek 1.8 yet? any starting problems with the 720 primaries?
