Ok this past summer I broke my final drive or LSD (still need to pull the tranny apart) Im going to repace with LSD and go with a 4.7 final no matter which one is busted. I want to go turbo but wont have the money untill end of next year earlist. So I was thinking is it worth having a Tune from my S200 Hondata system (non-boost) for my car as N/A, I have to buy a Wideband O2 anyway and bigger Ingectors, I already have a 255lph fuel pump and a OBD1 P28 that has been chiped with Type R base & has the 4pin datalogger in it. But is it worth tunning as a 97 JDM B18C-R with only bolt ons? Will be going to a pro for tunning. Then only money I will be wasting (since these are things I need for turbo) is on the tune.
