26-28psi stock turbo on E85: FMIC necessary?
^^ I disagree. The stock FMIC is very good for the stock turbo. I upgraded to the 3" ETS simply to fill the front bumper but I didn't see any gains from the upgrade. I wasn't heat soaking the stocker so there's next to no gain from the bigger unit.
If you are running E85, meth, or race fuel odds are you will see no gains from an aftermarket FMIC unless you are on a BIG turbo.

That's not the right way to think about it.
You actually need a better intercooler with smaller turbos, which you try to push hard, because they are inefficient and produce a lot of heat when pushed to max. Unlike for example a 35r that'll keep IAT's in check even at high boost.

I plan to switch to E85 soon and maximize the stock 9.8 hotside turbo's potential (for now, possible IX turbo or Green down the road). My car was in an accident recently and needs a new FMIC ASAP. BUT just because I have a good excuse to upgrade doesn't mean I should. I know pushing a stock turbo to the limits of its efficiency range usually means high intake temps, but many claim that the stock FMIC is good to about 400whp, the highest I would go.
I'm sure it won't hurt intake temps or do any harm in general, but will it be the most efficient, and still provide the fast spool I am after with this setup for a stock-based turbo?
Should I upgrade?

On e85 you really wont have to worry about knock, and itll lower intake temps by 10-20percent. I would still recommend a intercooler.

I have a gt3076r with stock intercooler. Right now the Intake air temps are around 150-160degrees at only 20-22psi. Doing a 2nd to 4th gear pull, the car will instant heat soak by the time 4th gear is done. Youll have to lower timing a bit to kill knock.

Somewhat off-topic, but a good DV should also be on the list for high boost. A leaky DV at high boost is a great way to cause a turbo to work harder than it needs and at the same time recirculate hot air. Its worse than a boost leak because the leaked hot air gets sent right back into the intake system.

Thank you guys for the input. I am somewhat ashamed to say that even though I started this thread, in the meantime I decided to postpone this next E85 stage and focus on autocrossing in STU for awhile, so E85 fuel mods and the intercooler are not allowed. Once I am ready for more power though, I will be making the leap and following your advice. I already have a lot of the parts just waiting. E85 seems like an excellent option for a BSP Evo without spending a ton on a build.
