Ok im kinda confused...
ive been studying various things about rx-7's and one thing im not really under standing is, from what i understand, the S4 5/6 ports open up using the backpressure from the cats and i read some people saying that taking the cats off will stop them from working. but when i 1st got my S4 the first thing i did was go and get a full straight pipe (starting from the exhaust manifold, no cats or pre-cats) and yet my 5/6 ports still work... at least it feels like they still work because i feel a kick around 4000RPM. so im not sure whats going on with the 5/6 ports. are they supposed ot be working?

If you get a TII your ushaly getting into another used motor. As well Kevin Landers has great prices on rebuilt motors to drop in. Just a few thoughts to consider during this time. Best of luck

You can purchas a drive shaft to convert TII tranny to N/A rear end from cork sports for $300 or you can ushaly find a compleat rear end TII swap from members for around 500$. SonicRat did have one a few months ago he may still have it. Try PM him if you are interested.
The trany cross member and the chasi of the two cars are identical!
Any swap or rebuilt takes alot of work and should only be done buy someone who has proper tools and place to perform the work.
To convert to a stock TII is not that bad. You need the motor compleat with turbo and intercooler. you need a TII ECU or convertable ECU of same year of motor, a TII hood, TII Boost sensor or presur sensor "same thing", TII MAF but not required to run. TII wireharness is not required you can adapt the wireing but does make the job a bit easier. You need to rewire the alternator exciter and temp wire if you use TII harness. a TII TID or make one is required. Thats it from what I can remember. As allways at this point all hoses and fluids should be changed.
But thats if you take this rought. It seems you are not that happy with your model. If thats the case you will be happyer if you get the model you realy want.
