lt1 info needed Hello guys, pretty new to the ltx motor. I am planning a cam swap for my 93 a4 z28 soon and this is my list of parts:
Cc503 cam
1.6 rrs
Alex spring lt1 springs
New msd opti
Pnp on the heads an intake
taylor wires
Mail order tune
My question is do I need different injectors, if so what size brand? Is a 3600 stall overkill? Anythink else I should get or change while I'm there?

I think some folks missed that.
IMO 22lbs injectors and ported heads/cam do not go together.
I would put an MSD cap and rotor on a stock opti NOT buy a complete MSD opti. Put the savings towards injectors.
Also consider your car is 20years old, it might endup needing a fuel pump to feed this. A perfect working order stock pump could likely feed it but again, your car is 20 years old so sometimes we have to change additional things..

Stay away from the Taylor wires. They fail quickly. Even new ones have been known to arc.
MSD wires work pretty good. Get fire boots for the plug ends.
My '94 ran best with the full MSD opti.

When you do the cam swap, be sure to match the cam dowel pin length of the 503 to your stock cam dowel pin length by either tapping it in with a mallet or grinding it down. It will cause major problems otherwise.
