    You can run 1.9s on a N/A but youll make less power than with getting the split ratio.The 1.9s will give you only bout 10hp whereas the split will net 15-20 horsies.So you decide.

    Hmmmm well I do plan on top swapping but I have no clue when... Maybe I'll just go with the split ratio for now then sell them or trade them if and when I decide to top swap

    Thats a good idea.But since you said youll top swap eventually then go with the 1.9s.They are suitable for supercharged cars and net you 20+ hp once you're supercharged.

    ER's dont net that kind of power...

    16 WHP from ER rockers.

    1.9's are 13 WHP.

    1.9's are for the blower cars.

    IMO, get the ER rockers with a HV3...and a 3" DP...it wins...for an N/A car it makes a TON of a difference...maybe a shift kit and a custom tune and new mounts next. Should easily run high to mid 14's from there...since yours is the freak one that went 15.3 basically bone stock.
