ThaiFiesta Posted January 17, 2018 Share Posted January 17, 2018 Hi, I'm looking at upgrading from my Mk7.5 Fiesta with a tuned 125PS 1.0 Ecoboost to the new Mk3.5 Focus with the 1.5 Ecoboost. I can see online that Bluefin and Pumaspeed do plug in tunes, but there don't seem to be many plug on or bolt-on swap out hardware options. What have people done to enhance their 1.5 Ecoboosts?

D13 HPD 95 Posted January 17, 2018 Share Posted January 17, 2018 They are still a newly released engine so many people haven’t had access to them yet to see if the bolt on mods work try speaking to Jason Tierny at pumaspeed he will give you the low down on what they have managed to get fitted so far 1 Quote Link to comment Share on other sites More sharing options...

The coolant system diagram I've seen shows the intercooler and engine coolant circuit linked - is that correct? Quote Link to comment Share on other sites More sharing options...
JW1982 Posted January 21, 2018 Share Posted January 21, 2018 Yes , the 4-cilinder 1.5 ECOboost has a watercooled intercooler. The 4-cilinder 1.5 ECOboost engine is expected to retire soon. On the new Focus MK4 (which will be released within a few months) this engine will be replaced by an all new 3-cilinder 1.5 ECOboost. Knowing this very few manufacturers of aftermarket parts develop parts for this engine. 1 Quote Link to comment Share on other sites More sharing options...

Hi iantt, do you think that a change of the front heat exchanger for a better one will not help? Or actually the most important is the IC core inside the engine? Cheers for your opinion. 1 Quote Link to comment Share on other sites More sharing options...
