u can get hondata, but u'll have to convert to obd1
The one i've seen a few ppl use is the aem ems
For cold air intakes there is AEM, Injen, etc. Check out the intake review thread in the product review forum.
I don't want to do a OBD1 conversion, as I don't have the money and need to save it up for the regular repairs and maintenance, as I will be drowning in student debt in a few years for going to medical school.
I will check them out.
if you dont have money dont even do a tune. you wont gain anything with a stock engine + an intake.
If you have the V6 your only piggyback option I know of is AEM FIC-6. You would need to have someone make and possibly wire up the harness for it though -- $$$.
Throw on a set of headers (have someone reweld the primaries, they always crack there after a few years), lightweight crank pulley, Short Ram intake (works best for the J30A1) and be done with it. That will get you the 10-15 WHP without a tune.
You don't need an ECU tune for those minor mods.
