Which 2.5L did you use? Old ver or New ver? Old 2.5 spec is 165hp @ 5600rpm / 166tq @ 4000rpm. While new one is 170hp @ 6000rpm / 170tq @ 4400rpm.

My friend own Si, but it sure doesn't look fun in the 5" of snow...

i used the 170hp version. i bet the Si doesn't like that much snow, especially if it's lowered, haha.

Wanna elaborate on that...???

one very important thing to keep in mind is what kind of fuel is being used. the K20 requires premium, while the Ford, Toyota, and Subaru engines i used all run on 87 octane. i will happily pay for premium if the performance lines up with the K20 as opposed to the others.

This motor will definitely run on premium to get the compression and ignition that is required to make torque numbers anywhere near what we are talking about. Still I don't see torque getting much higher than 150 lb-ft at around 4500-5500 rpm.

I used to own an Si (prev chassis, EP3) and it had a kit, was lowered, etc.

On winter tires (and a mildly raised suspension), that car was awesome in the east coast winter. AWD is great fun, but FWD is just as confidence inspiring in horrible snow. It's the tires that matter.

I think NESW20 has got it right. Have an RSX-S now with the K20Z1 (US Spec engine) and I'd say the FT-86 would be awesome with a similar, high-reving power plant. Would like more torque though, that's probably the chief complaint with the RSX-S at 143lb-ft. This engine is slightly more powerful (211hp) than the K20Z3 in the current Civic SI (not by much tho).

Related question - I know the concept car was a 6-speed manual trans (loved the graphic-matched alum pedals, hope those make it to production), but do we have any info on the automatic? I wonder how many speeds we're expecting, and if the interface will be wheel-mounted paddles or tap-shift.

As you probably know, the only significant difference (at least, that I am aware of) between the K20Z3 in the Si and the Z1 in the '05 and up RSX-S are the cams. The Z1 used the JDM Type R cams.

As far as the tranny for the FT goes, I'm pretty sure Toyota will come through with the 6 speed tranny like in the concept. It's not that uncommon to see in a low 20k car nowadays. Whether or not it will be the same model as the concept, though... only time will tell.

Nice one, best joke I've heard this month.

Marine engines work all the time at maximum torque. At this rev point, they have a given max power. They don't even throttle them to alter speed, they change the prop pitch in the pods.

It was quite funny though.
Try to read more and stay in automotive fields, it seems you know more on those...

PS I don't mean to offend you but misinformation is flooding the Internet so please don't add to this phenomenon.

Thanks

horsepower is simply a function of torque and RPM, so it is entirely possible for an engine to make max torque and HP at the same RPM, it just depends on the shape of the torque curve. the engine would need to be fairly peaky for this to occur, but it's possible.

you're the one that made an absolute statement that isn't true...

This is an interesting thread for sure. Honestly I don't care what they put in it. If I don't like it I'll take it out and put in something that I feel suits it better. Now if the chassis isn't to my liking I'm gonna be upset

But to the topic. I don't think any current toyota 4 cyl suits this kind of car. It makes a ton of sense really.
