Is it possible to run e85 on a stock internal boosted b16a?

 

Yes. Btw you can run e85 in anything that takes gasoline.

 

^Yep. With proper tuning of course. Don't just assume you can put it in and go. I ran my b16 n/a on e85 for 2 years before boosting it. It's still on e85. You can run it in anything boosted or n/a, makes no difference. Just gotta tune for it

 

If you want to covert from gasoline to E85, you will need approximately 30% more fuel volume to support the same power levels, but yes, you can switch between the two.
