right now i have a chipped ECU from Ash. still havent gotten the tuned chip yet to see how much power it produces. my 94 is obd1 so i got a cable and program from one guy off these forums a while back. its like a version of conzult. ive used it to hook up to my friends 300zx with success.
when i had z31 suspension i did not have camber adjustment. i found through driftday that the evo 8 camber plates fit and ran with a set of tein's to put on my uhhhh....frankenstein suspension setup. you might be able to find a way to mount the camber plates to the J30 struts. i never tried it.
