MotorTrend Review (EcoBoost)

[REX-RACER]

Only the exhaust manifold itself is built into the cylinder head. The turbine housing bolts to the manifold. All it would take for a turbo swap would be to have an adapter that bolts to the exhaust manifold with whatever style flange you need for your turbo.

Don't expect to see anywhere near 400hp/400tq at the wheels on a stock turbo. I can see 400tq at the flywheel, but not horsepower. I don't *think* the pistons are forged. I very well could be wrong on that. If they are forged, this motor has big power potential with a stock bottom end. If they are not, I don't see 500whp being achievable without swapping to forged. I would love to be pleasantly wrong though for sure

I dunno, given the 20% - 30% gains places like Cobb, Lethal Performance and others have regularly and safely seen on the Focus & Fiesta ST it seems like that might be a reasonable bench mark. It also doesn't seem like I'm the only one flying this silly notion:

What I'd like to see is a compound turbo setup designed for the Ecoboost Mustang that still uses the stock turbo... Theres a guy on one of the dsm forums who built his own compound turbo setup for his AWD Eclipse using an mhi b16g turbo and a Turbonetics 60-1 turbo and made 609whp 541wtq on a slipping clutch! and kept it's street manners, hopfully Helion will jump on the Ecoboost 2.3 and build us a kit!

Forged slugs aren't necessarily needed for 500whp with a 2.3L as long as the head flows and a great IC or octane boost is in place (E85 or water/meth injection).

You're right about the stock turbo. I don't think the bottom end will even remotely be the limiting factor with this motor: it's that small oem snail that's clearly designed to spool up fast rather than make power up top.

Sometimes you don't really need to see the compressor map; occasionally the dyno says it all. This is one of those times. That dyno screams for a bigger hairdryer (as do most ecoboosts in fairness -- at least it's consistent).

Do you really think E85 is an option? Thus far I've heard "corn" has been strictly verboten in DI/T cars, something to do w/ the high pressure side fuel pump and I also suspect that some rubber has snuck back into to the fuel systems where they'd previously been "hardened". If you have some links to DI/T cars I'd love to read up on them?

I love E85 and run it in my '01 Cobra. There's a station 2 blocks down the street from my house that's selling it today for $2.55/gal! :shocked:
If it's possible to run the eb cars on E85 w/ a tune I'd definitely be in for that but I'd want to see someone else do it in a safe, reliable, non-warranty voiding manner first?! :shrug:

It is not only possible, it is happening right now. Visconti Tuning is doing flex fuel tunes for the DI/T 2015 WRX and FXT; basically, on-the-fly e85 tunes. His website is here: http://store.vtune.us/collections/subaru-wrx-sti-dit-2015

The damn thing is running times in the 1/4 mile as quick as my 1967 Fastback 390 GTA. Of course my '67 was running 3.00:1 gears in the open differential. She was running through the traps in 2nd gear at 5000 rpm, shifting as I lifted, at 98 mph or so. Oh how I wanted some 3.70s and a Detroit Locker in the 9 inch!
