The 2.3 block has 2 major issues that can lead to a cracked block (ECOBOOM) IMO.
The 2.3 is an open deck which is structurally weak, where the 2.0 block has a semi-enclosed deck. The other issue is the external area between cylinders 2 and 3 is thin and prone to cracking once you start trying to push more power.
This is why all the pro tuners limit the stock block to 400hp, but IMO it's still a ticking time bomb. I have heard good things about sending the 2.3 block off to https://cylindersupportsystem.com/ for their CSS system and added bracing, but at the tune of $635 (doubt that includes shipping).
Where as you can grab a brand new 2.0 Fusion block from Tasca for $800 and it's nearly identical to the 2.3 block, but without the inherent weaknesses. You can build it up with all the internals 2.3 internals and all the other parts mount up perfectly.
people have been pushing 700 hp + with these blocks, so they seem to be able to handle anything you can throw at it.
Although, even with a built proof block, the cylinder heads apparently flow like junk which leads to the next major issue with this platform- head lift. Speed Performance has a great youtube vid on this
I've heard that even with advanced porting they still are underwhelming.This is why SP created some super strong head studs that I picked up for my build.
As long as it makes you happy that's what matters. No mod is a bad one if it makes you happy. Also with the Ecoboost you get all the cool pops and bangs.appreciate it man! She will never be the fastest, best sounding, or win any car beauty pageants (especially with my DIY vinyl skills) but puts a smile on my face every time i get behind the wheel! never been on the strip, but my goal is to put down a 10sec run by EOY. Also really want to try some autocross racing, but will probably wait until i upgrade the brakes and suspension
my lord that thing is going to SCOOT. I'm hyped as can be about this build.big turbo kit should be mounted up this week! just need to add in port injection to make her a 550hp monster
just picked up a 5858 to swap out the 6262
Also found another score on Ebay for a full GT brake set for $300.
