fb sites

does anyone know any good sites for parts or even just info, anything at all for 1st gen 7`s? mainly parts is what i need though.


also thought i would ask if a 13b from an fc can drop into a gsl-se fb that also has a 13b. im not sure what, if any differences there are between the 2.

search for the gsl-se T2 swap in the 1st gen section on the rx7club.com's board.

a 13b from an FC will fit perfectly. all you need to do is to keep the gsl-se front cover, gsl-se oil pan, gsl-se oil pickup tube and the gsl-se tranny. if you choose to go with a T2 engine, you'll have to mess arround with the OMP and also to drill a hole for the oil return line in the front cover, but its an easy task, i have a friend that did a cosmo 13b twinturbo swap in his gsl-se, he took many pictures, i can dig em out if ur going turbo.

if the car is equiped with a 12a, you'll have to buy an engine mount or have one fabricated. and you'll have to buy the gsl-se stuff too.

i did a 13b swap in my 81

very helpful as always. thanks!

i would assume that u need a tII tranny in there also, but can it really go in w/o killing the se tranny? not sure i would want a tII or not, just maybe a later n/a. o yeah, i found a nice gsl-se i should be picking up next week, which is y im asking this. hehe.


also anyone, all 13b`s are a 6 port right, except the 12a`s that r converted to a 13b? just checking!

you'll need a TII tranny.... non-turbo trannys are pretty weak... and I would expect you'd want the rear end as well...

hey soyo, take no offence but.. stay in the FC stuff

you just cannot fit a T2 rear end to the solid rear axle

the gsl-se tranny will hold up ~250hp, if you plan on doing more power, you'll need custom tranny mount and a custom driveshaft to fit the T2 tranny

the stock gsl-se rear axle will hold up just fine, plus its LSD.
if you want to upgrade it, you can get a '94+ miata lsd, those are torsen lsds, with better gearing.

check out this page, its full of good information, i forgot to send you the link previously

the will "X from Y fit on Z" will explain better my points

6 port 13b's : from 84 to 92, all pre-rx7 and turbo 13b wer 4 ports
and if you wanna build a 13b out of a 12a, you'll need to use 85 or older rotor housings, in 86, waterjackets have been modified and do not fit older rotary engines .

thanks once again. what i may do is either build up the stock motor, its an 85 gslse so it is the 6 port 13b, or i may get a 2nd gen n/a 13b, still maybe even a tII, i dont even know yet. but all the info is quite helpful.
and i also finding tons of parts, so all is good and i should have the car in under 1 week! muahaha!
ah, im still going to need some stock exhaust parts, just the part with the cats i think. its all stock, except it has full exhaust, so im going to need some cats on there (temporarily) to pass emsissions. anyone know a good place to find used ones? i can get new ones, but dont want to spend the money for a part that will be on a day or two...i was just going to try over at 7 club.

<== idiot! I wasn't even thinking about an FB when I replied... dang I gotta stop posting here late at night... but yea I don't think its possible for the FC rear end to go on a FB just ignore that part of my post haha

I don't know if a TII engine will work with an FB tranny or not, never seen it done before

[NuTbAgSaN]

ive heard of the tII, i just never bothered to ask what tranny it had!

< understands the effects of posting late at nite.

a 1973 12a tranny will fit on a 20b-re, they are all interchangeable
