Nothing special about running E85 and oil. Just a sooner interval as every OEM has suggested since it began in 1996. It's easy to understand why. It consumes more so it's based on how much fuel is burned/used. Fuel consumption is key. E85 uses more. Not really hard to figure out honestly.
One glace at the dyno sheet and I can tell you it needs work. From the looks at it, it has never even been tuned. I would get a good wideband installed ASAP (I recommend this for any Forced Induction Car) and I also recommend a proper tune.
If you stay with 93 Octane, then 60# or 80# injectors will work fine. If going E85, then ID1050X. Yes, always replace the stock idlers as they will fail. Metco makes the best ones.
I would recommend a Return Style Fuel System with proper injectors for your fuel type and power level, a Twin Disc Clutch w/26 spline input shaft, and some good sticky tires.
I could have easily bought another Terminator several times. Still can. But it was time for me to move on to different experiences. I still stay very active around the community and tune them daily. They will always have a place in my heart, but I have no plans on buying another.
