Ok, here's my question. I have an 89 N/A 5spd that I know that I will end up doing a GTE swap at some point in the future. I would like some advice on what would be the best "semi" buget upgrade that I would still be able to keep if I did the GTE swap. I already have a Pacesetter 2.5" cat-back and am leaning toward doing a R154 swap next. Everything else is stock. I just need some advice as to what would be the next best step that I could still use if I did the GTE swap. Thanks for the help.:icon_bigg
