Hello. Think its finally time to get out of the past with, retire my 01 integra, and upgrade to something newer. I think the key thing i'm looking forward to is the 1.5T engine. Just wondering how the reliability would compare to the larger displacement, naturally aspirated engine options... could anybody possibly chime in and provide some insight ? The body styling is already a big plus for me so it really comes down to motor choice ;)

Sadly it's hard to say definitively which engine will be more reliable in the long run since the 1.5T is a new engine. That said. It's still a honda engine, so reliability shouldn't be an issue. Afterall the 2.0L is the one that had the recall already, not the 1.5T.

I do know there are some long term maintenance cost associated with turbos after the first like 3-5 years, but not sure how this engine compares, i hear about VW owners complaining about it though. Again, honda might have worked around that issue.

Obviously a turbo has a few more moving parts, and turbos can go bad and need to be replaced. But i think it's a safe bet to say honda has spent many years building, testing and refining it's new turbo engines to be just as reliable as their N/A engines have been, that's why it took so long for them to jump into the turbo game like other automakers. So it's really a toss up. Test drive both... if you can live with the lower trim levels of the 2.0L go for it and save some money, put that money into mods or upgrades. I personally loved the new 1.5T and it's torque and power is excellent for this segment and price of car, not to mention the extra 1 or 2 mpg the turbo gets over the 2.0

That is true.. I guess it also comes down to how you treat it as well, i.e giving it cool off time, warming up, etc.

That was super informative though, I really appreciate that.. Kinda makes sense as to why I'm now seeing an Oem boosted honda engine.

Any idea how the torque curves look comparing the two (1.5t and 2.0) ?

Honda was conservative in limiting the boost to 16 psi with their turbo (Fiesta ST makes 22 psi), but it's still boosted, which puts more strain on the parts because of increased power. The magazine reviews of the 2.0NA with the 6MT gave the combo high marks.

One thing for sure is within the warranty timeframe you won't have to worry but i'll be very concerned about it's reliability with a lot of miles (high mileage range) when off warranty.

How long do you plan on owning it for?

That's a bit more than I was expecting, I was thinking it would have been in the 9-11psi range, but thanks ! Know of any articles that may provide an insight on differentiating the power bands ?

Yea that makes sense.. I would probably be keeping it long term, in the range of 6-8 years perhaps ?

Do you think engine internals would be first to show problems or turbo ?

When Honda quotes the 2.0 NA at 158 hp (6500 rpm), and 138 lb-ft torque (4200 rpm), in order to see these figures you have to wring it out. With any well-tuned turbo (including Honda's 1.5 T), you should start getting boost lower in the powerband (~2000rpm).
