I just did the 86,87 computer swap.works so much better .you get to use a scanmaster ,upgraded maf and a TT chip. Don't short change your car do the upgrade.
I did the 86/87 conversion too (same as blacazz) this spring and WOW a discernable difference in how the car performs. Plus the Scanmaster allows you to monitor the systems. Its a little pricey, but in my opinion, well worth it.
