Seems hard to find kits for pre 96 sti. Bought an Autobahn 88 kit for a 96 up and modified it to fit. Mods were , remove turbo shroud cut turbo end of intercooler pipe before weld on 1st bend, enlarge hole at air filter where it enters firewall . Shorten small diameter 1st pipe so it matches to second pipe ,all other bits fit ok. You will need to run a pod type filter though.Also replaced std turbo to intercooler pipe rubber rt angle hose with an aftermarkrt item ( sparco ) as this has no bov outlet .This kit has a bov fitting on inlet pipe.
