New rumor: 1.6-liter turbocharged engine one year after initial introduction

In any case, the article also mentions that the new turbo engine will be fitted in the new Subaru Impreza WRX STi as well, producing 270ps. BC also claims that the differences between the FT-86 and the BRZ (or whatever the official name will be) will be on the front and rear ends.

Can you send me a larger picture or attach a larger picture? Or... the issue number. Lol I'll go out and get it or someone on here could translate.

Lawl!

Not too small. Nissan was planning to use a 1.6T in the S16. Honda's B16A/B's are animals with a turbo strapped on them. WRC is 1.6T. Formula one going to 1.6L next season.

How much more performance do you want?

I hope Scion/Toyota looks at these forums.

I would hate to buy an ft86 when it comes out only to have a turbo version come out a year later. Im ready to get the best model on release!!!

Turbos. The replacement for cubic displacement.

270hp turbo 1.6l FT86? sign me up.

Saw this car in person at Autoclub Speedway during S2K Challenge. There was some Honda event that day as well. I don't think it went out on the track (at least I didn't see it go out), and I was there the whole day. It just sat there looking pretty for people to check out the nutrition facts and take pictures.

Imagine the Rev-Range of that puppy!

maybe with the impending CAFE laws, etc. our standards for performance are slowly going south...

You own a 2.0l turbo sedan with 3,500+ lbs of weight. What is wrong with a 2700+ lb coupe with a 1.6l turbo? That's 800 lbs less.

again... WRC and F1 have NOTHING in common with streetcars... yes some of the tech can be trickled down but most of it is simply not practical on a street driven production car. WRC has anti-lag. no production car on earth would ever come with that system and have a warranty. the 80's F1 cars had a 12000 rpm redline. you think a production car is gonna have 12000 rpm redline?

slapping a turbo on a 1.6L engine cures NOTHING. you either have no lag and make moderate power or you have tons of lag and make crazy power. in the middle you have a compromise that doesnt spool fast enough, and doesnt make enough power. it's lose-lose.

and for clarification we're strictly talking about a car like the WRX/STi here. if you want to talk about something like the next gen miata or a 2200 lbs sportscar then yes a 1.6L turbo would rock. otherwise 1.6L is just too small...

what's "wrong" with it is the shape of the torque curve. it's either going to peak early and fall off rather rapidly, or it's going to be nonexistent and then shoot up exponentially. both scenarios are not to my liking.

instead, my ideal engine would be a supercharged 2.0L. with the correct engine geometry paired with the newer highly efficient blowers, the power and tq of such a motor would be the happy medium.

its about the SHAPE of the curve, not the peak numbers. its about the area under the curve. its about the real world rpm range, while still having plenty of revs for track days and auto-x. its about torque where you can actually use it on the street. its about how it feels to drive, not the dyno numbers.

I definitely give those guys two thumbs up for the CRZ project, but when it comes to daily drivers 2.0L already has quite the hill to climb. Why give yourself an even larger handicap in a car they have every intention of trying to get more power out of? It's like asking a starting quarterback int he NFL to chop off the thumb on his throwing hand, unnecessary handicap.

If I'm looking for economy then definitely give me a 1.6L or smaller, but in a performance car 2.0 is the smallest I'm going. ***

WRC also has restrictors to choke the hell out of the motors so they don't get too powerful.

A 1.6L Turbo with high (for FI) compression, D4-S, properly tuned manifolds, cam phasing, and a twin entry turbine would spool very nicely even in the 270 hp range. If they got fancy with variable geometry turbines, even better.

I figure for max power of 270 hp @ 13-14 psi around 7400 rpm.

Yes it would have to scream a bit still because it's small.

Alternative is more boost and less revs.

We're probably going to see this turbo 1.6L for sure in the WRX. Whether the factory puts it in the FT86 twins, who knows?

Who said anything about a 12000 rpm redline? BTW, Lexus was going to do it with the LFA, but pegged it at 9500rpm.

And WRC nothing in common with street cars? Seriously?

BTW Evo 4-9 came with anti-lag. I think you guys must have missed out lol!

You better run and tell BMW, VW, and all other european manufacturers this, because they seem to be doing it wrong by your accounts. Granted they do use supercharging as well, but you make it sound like it's impossible. It has been done, and there is more than enough cars out there on the market that says you're wrong, and a lot of them are less than 1.6L!

Thought we were talking about the FT86?
