oh yeah the si tranny will be alot nicer than the long geared slow hf but you will need to change your hubs (dx or si one will work) and cv axles or else your cv axles will not lock in it will drive fine but leak oil out the tranny pretty bad plus on getting a clutch make sure it is for the right year tranny because the 88 has different splines on it been there on all this and it sucks but after it was all done it was well worth it
