Wherever you can find a way to loosen them, it doesn't matter. The bolts are fairly easy to get to from both.

So when i jack her.........does it need to be higher than like an average jack stand? Ive seen pics of people getiing them up 2-3ft, i think people only do that if the motor mounts are bad and if they cant get the LTs in at all. Im going to get a hook up from one of my buddies working at SEARS, i need some jack stands.

You'll need to get it up high enough, but if you can't, jack up the motor. Put the jack on some boards and get some jack stands.

And then when and once i get the LTs in, im not going to get an ORY becasue im just going to get True duals, so im going to need o2 extensions right? Some people say there cars start running like **** if there run open headers, some say it doesnt effect it. I guess im better off just gettin extenisons.

Uh, what? Holes? Running open headers isn't a good idea volume wise and is not recommended by a lot of people. You need to disconnect all the AIR and EGR and get them programmed out of your PCM and get block off plates for the EGR. The LT headers should already have the O2 threads in them..

Im not going to get an ORY, i cant afford it, so will running Open headers make the PCM think lean and rich? Im wanting to run these on the 1st of october, because thats the last race, then on the 8th im gettin my True duals. But if its going to kill my MPG and make my car run funny.....

A couple things. You will need to extend your O2 wires but on our 93's, we use single wire O2's so you can just cut and splice wire to extend your existing O2 sensors. No need for buying extensions. Also, lots of guys with 93's have trouble getting their cars to go into closed loop with the non-heated O2's. Since youre moving the sensor further away from the motor, a heated O2 is needed to get the proper reading. It might not be a bad idea to go ahead and do a heat O2 sensor swap while youre at it.
