Perscitus Posted March 14, 2015 Share Posted March 14, 2015 Myles or someone else from RCE posted this up earlier over @ NASIOC... A Motortrend spy shot of a 'prototype' STI with FA20DIT in sunrise/sunburst yellow, testing at Suzuka Circuit. Supposedly a decent bunch of chassis and suspension upgrades over the current WRX/S4/STI/Levorg. ETA? Who knows, perhaps MY2017/18. https://instagram.com/p/0J0V_XIx67/ Link to comment Share on other sites More sharing options...
NewLegGT67 Posted March 15, 2015 Share Posted March 15, 2015 Me Like!! I don't think I would want the rear spoiler for the street. I'm probably the only person that has Wu-Tang Clan and Paul McCartney on their mp3. Link to comment Share on other sites More sharing options...
BDII Posted March 15, 2015 Share Posted March 15, 2015 That might have surpassed the Aztek as the ugliest car ever. Need forum help? Private Message legGTLT Link to comment Share on other sites More sharing options...

TrueWhiteBoy Posted March 17, 2015 Share Posted March 17, 2015 I like it. More importantly though, I want to know what kind of numbers that engine is making. Link to comment Share on other sites More sharing options...
dgoodhue Posted March 17, 2015 Share Posted March 17, 2015 I like it. More importantly though, I want to know what kind of numbers that engine is making. As far as I know it isn't confirmed, if it has either the FA20DIT or EJ207 motor in it. Link to comment Share on other sites More sharing options...
Perscitus Posted March 18, 2015 Author Share Posted March 18, 2015 Its possible that its either of the two engines, although the EJ207 (which Japan gets in the current STI as-is) wouldn't really require any type of mule or prototype then. Instead of going EJ207, they might as well use the 5th gen LGT low mounted turbo EJ for the 2015 if that was the case. Development done, 3 model years of USDM LGTs for beta testing. There is also the FHI/SoJ statement of having every car using DI by 2017. It wouldn't make sense to modify the EJ so much when they have a new motor designed for these technologies already. My vote is still FA20DIT, since I doubt they'd have an F*25DIT or E*30DIT ready. Link to comment Share on other sites More sharing options...
dgoodhue Posted March 18, 2015 Share Posted March 18, 2015 This is a press release from Fuji Heavy Industries from May 2014 that mentions adding direct injection to the entire line up. http://www.autonews.com/article/20140509/OEM/140509810/subaru-plans-more-u-s-capacity-unveils-new-technology "Among the new products on tap is a seven-seat SUV geared toward the North American market to replace the aging Tribeca. Subaru did not give details about the vehicle but said it will debut sometime between 2016 and 2020. The production site has not been finalized, but Yoshinaga said the company is leaning toward manufacturing the vehicle in North America. The vehicle could plug the gap created by the Camry pullout. Subaru will also convert all its gasoline engines to direct injection, starting the same year. The technology will be standard in a next-generation boxer engine Subaru will roll out." The press release gives a vague release date of the seven seat SUV and rolling out direction injection on the next generation boxer engine (suspected to be new H6) and doesn't give a timeline for adding direct injection all engines. Supposedly the FB25 is already designed for DI. The FB20 (Impreza/Crosstrek engine), FA20 (BRZ), & FA20DIT already have DI. The STi's EJ engine already has the writing on the wall.

derkahn Posted March 23, 2015 Share Posted March 23, 2015 start @ 2:30 ish to speculate on power for the FA20 Link to comment Share on other sites More sharing options...
wankey Posted March 23, 2015 Share Posted March 23, 2015 430hp vs 360hp just by using the same turbo... so by that logic? new STI should at least be at 375hp? Link to comment Share on other sites More sharing options...
jshute Posted March 25, 2015 Share Posted March 25, 2015 Oh god, now they look to direct injection and a new yellow. Come on subaru i don't have the cash for this right now! Sent from my DROID X2 using Tapatalk 2 Link to comment Share on other sites More sharing options...
dgoodhue Posted March 25, 2015 Share Posted March 25, 2015 430hp vs 360hp just by using the same turbo... so by that logic? new STI should at least be at 375hp? The video doesn't really give any technical reasons for FA20 vs EJ25 making more HP. Is the gains just from the direct injection allowing for more aggressive timing? Is DI allow for higher boost? Does FA have better air flow through the engine despite the smaller displacement? Is the FA motor design more detonation resistant and it allows more timing & boost?

Is the FA motor design more detonation resistant and it allows more timing & boost? DI allows for a multitude of benefits: - Higher static compression ratio (off boost) so you can build boost faster - Better fuel mileage since now the engine can run absurd AFR (up to 40:1 on non-turbo applications) in cruise / low load state. - More control on knock, as the ECU has precise control over the fuel amount injected Also comes with cons though: - Carbon build-up in intake manifold and valves (gas is no longer being injected at the intake ports and washing down carbon deposits) - Significantly higher component costs for fuel system Link to comment Share on other sites More sharing options...

DI is only used for when you are on the pedal, the port injection is used when cruising. So you minimize the carbon build up issue. Link to comment Share on other sites More sharing options...
