Fuel system question....

ok, so the sl can use a tt fuel pump without any problems(right?), but what about tt injectors... will my car run too rich if i put in 360cc injectors?

why would you want to put 360cc (tt) injectors in your sl? your car already runs quite rich with its stock injectors (210cc or 220cc, i can't remember which). the only reason to upgrade injectors on a NA motor is if you have gone Forced Induction. if you don't have turbos or an sc, then don't worry about it. and don't worry about the fuel pump either.

adding more fuel to your motor won't make any more power w/o adding more air.

I am planning on doing the tt conversion, but i kinda wanted to plan out stages to do it in.... i know i could do the fuel pump, and still drive the car, i could probably switch the front motor mount bracket, but i didnt know about injectors

While the injectors physically fit, they are a different type of injector and will require resistors put inline with them. You will also need an AFC.

well, i ran my injectors for probably 6 months, driven daily, without resistors and had no problems, however, i still would not recommend doing that for a long period of time. Find yourself six 5.6-ohm resistors and solder them into your fuel injector electrical wires. There's probably a diagram of where your wires are located on www.bobthregreat.com

And yes, as talskinyguy said, you will need some sort of air-fuel controller when you add on the injectors.
