I don’t think they make mustang motors. All I see is focus, fiestas, and f150s
Not sure about the 2.0 short blocks, I've been told the enclosed block is stronger, but runs hotter.
I think you'd be hard-pressed to beat Jessie Ringley at EMS. I've run both engines in a racing environment. It's not even a contest, the 2.0 is far and away the stronger option. Whatever cooling issues that the open-deck is meant to solve is minor compared to the blowing the side out of the block.
Based on what I’ve read the 2.3 RS block is the same as the block in the mustangs. Most people who have gone big power with these cars have gone 2.0 block due to it being better for reliability and can handle more pressure.
From ems, is there much of a difference between the budget build block and the other shortblock?
I can't tell you; You'd have to talk to Jessie. His budget block looks like it can hold 500HP with good reliability, though, so it really depends on your goals.
For $300-$800 more 200 more hp seems like a no brainer… thoughts?
From what I have read on ecoboost engine building sites, the ones that offer the 2.0 blocks are using factory ford oem blocks with 2.3 internals. The prices seem to vary depending on which piston, rod, bearing, etc they are using. And I think that is just as important as which block they are using. My theory (and that's all it is) is that if you put cheap 2.3 internals into a 2.0 block and you run it with the same tune and manner as I do... you're still going to have problems. My internals may not come out the side of a 2.0 block, but they will come out somewhere or at least lock the motor.
Personally, when I blow my open deck, I'll probably end up with at least the 10mm head studs & H-beams, but project creep is a shortcoming of mine.
For me... spending the extra money and getting better internals would be the wiser thing "for me" to do, because of poor engine management (knock and excess heat) and mismatched bolt-ons (DIY and eBay).
Yeah but that’s if you wanna risk another engine again. I think it’s smart and will be more rewarding paying for the higher dollar for the better reliability and power output. This is the functionfactory performance spec of the ems shortblock. https://ffperformance.co/product/en...0-ford-mustang-ecoboost-ffp-spec-short-block/. Thoughts?
There are a lot of unhappy Function Factory customers and Sithiro is, shall we say, a bit free-wheeling with the truth. It appears their special spec is actually Jessie's lowest spec with a $1500 upcharge. Just get the engine from the guy doing the work.
