ST Super charger help, HELP Options

[SinisterSinner]

does anyone knows where to get or if there even exists a supercharger for the 94 celica st? or at least one that could be modified to fit it

I think that because of the expense of supercharging an ST, it isn't really going to be worth your time. The gains you'd get by supercharging the 7A are going to be pretty nominal, and considering we're not dealing with a lot of HP to begin with, IMHO it's really not worth the effort if power is your goal. Now if your goal is just to build a fun project, then go for it. Just don't set your sights high in terms of any significant HP gains.

Mstoochn is right, if you're going to supercharge a 7A, your best bet is to retro fit the head with a 4agze head. That will lower compression and net you better gains than just straight up trying to supercharge the stock 7A, although IIRC you will run into some interesting challenges with fitment, and possibly with electronics as well, as I believe the stock 7A ECU won't really do much for you with a charger setup.

If you're looking for more power w/an NA setup and you really like the idea of the supercharger, your best option is going to be to just do a straight 4agze swap. Again, for the money though, you'll still net more power by building up the 7A with a turbo application. Or better yet, swap in a 4age head and THEN turbo it (7AGTE).

Really, it depends on what your goals and motivation are.
