So I am puting 3.73s in my car after that what should I do LTs and a Y pipe or 1.6 RR, LT4 KM, and LT4 springs. Which will give me the more horse power and which one is easiest to do??

Thanks

 

If I were you, I would do the valve springs and rocker arms first. Not sure if it would be a tie for hp, given your mods, but if you got original springs on a 94, they are shot anyway, so new ones will wake up your car, especially since you are doing a gear. Then maybe do a converter, then heads/headers/cam.

 

1.6 RR, KM, and springs are easier...but yield less hp (maybe ~10)

LTs and Y-pipe aren't necessarily hard - just time consuming....but very doable. Depending on your luck, certain things will slow you down.

 

I agree you could probably use some new springs anyway if they are original - I've just always liked making the motor breathe easier before anything else.

 

I'd do the exhaust first. You will see more gains from the RR that way when you do get to install them.

 

The best gains will come from the exhaust work but will be more difficult to do versus the rockers/springs swap which will be a easier but most likely not yield as high of gains.
