Put a mikuni 44phh on it with the RB header system, lightened steel flywheel. After that you will be saying " DAMN, RX7doctor sure is a wise man",lol. rx7doctor

that kind of answers a question i had. are the intakes for the 13b 6 ports different than the 4 ports or turbo engines?....if i had a gsl-se 6 port with rb intake, could i use the same intake on a TII engine? i guess not?

Proper 6port inlet manifolds should have seperate tracts for each of the inlets on the end plates. I have previously had an aftermarket one that didn't.
I believe you can fit the 2nd gen turbo inlets to a 6port inlet but the air flow gets nasty as the ports don't line up.
Were you after stock or aftermarket inlet manifolds? I use a 48ida on my 6port and use the aftermarket inlet manifold. I wouldn't have called it rare....
You can get adaptor plates that will mate an early factory 13b carb inlet manifold to the later 13bT block - it should therefore be doable to make an adapter to fit any 13b inlet to a 6port ~ with the actuators removed.
My 6port was rebuilt with a late 1st gen centre plate, and the centre plate tracts and the 3rd and 4th tracts in the end plates bridged. Its only being run in, (the carb is set for a stock6port and the timing is at about 0deg) but it seems to show promise.

one thing i missed to ask...
will the intake manifolds, header, etc. work for an 86 and up 6 port 13b, from a 84-85 gslse 6 port 13b? is the only difference between these motors the internals?

If this is an S3 6 port, use 12a end plates and bridgeport it. I personally think the 4 port has far more potential than the 6 port. It's easier to get past 200 hp with a ported 12a than it is 6 port.
The only thing I haven't figured out yet is a good source or choice for the intake manifold. There are, however, adapter plates to go from 6 port to the 12a intakes. Finding one might be an entirely different matter.
