stay with 19s unless you are doing cam to go with those heads , not to mention a MAF ..... stockers should be more than enough AFPR is all you will need ......

19#ers are good up to 270hp or so there about, with an AFPR.

I heard stock injectors are good up to 350 flywheel horsepower.... but that is pushing it. So that is like 290-300 RWHP?

I wouldn't say the 19lbs will take it easy in the upper rpms but if you add an AFPR and bump it up a bit you will be fine...even in the "outrunning the injector" high-rpm phase...

Just to let you know the 93 Cobra has similar modifications done to it as your car has and it comes from the factory with 24lb injectors/matching bigger MAF...

You dont need them but when you decide you need replacements you could go one size bigger! If you have the stock cam I would sure like to see some 1.7 Cobra Rolling Rockers. Of course I am sure you know that new heads would make those bigger injectors really purr.

so will would a set of 1.6 or 1.7 rockers be better with stock cam and thumper ported heads?...thanks for the help ill prolly just get the AFPR for now and add the 24# injectors later on down the road when i have money and if i add a 75hp nitrous system

Well if you get the thumpers with the gt40 spring upgrade the 1.7's would be fine...that is what I had on my stock headed/springed heads so they would be fine with your stock cam with thumper heads/upgraded springs...

i would get the 24s and upgrade your MAF while your at it if you got the cash.

i would go with 1.7 rockers too with the stock cam and those heads. you will see more performance out of the cam and see what you want with those heads.
