RPMS!!
 

Lets just say this is going to be a 2.0 N/A boxer motor. With that being said how high do you guys believe this thing will redline at?

realistically, 7000...
hopefully around 7500...

but cheap cars have cheap engines. the engine in all likelihood wont be a rev monster. with DI added, and if the long stroke seen on the FB20 is any indication, my guess is that they want more torque. high rev low displacement 4 cylinders usually have peaky power. nobody wants that. both the S2000 and now Civic Si went with a displacement increase to deal with that. what i personally want is a flat tq curve.

over 9000



:D

yeah maybe with some formula atlantic steel cranks xD

Well, to reference another lightweight, 2.0 N/A car that doesn't focus on power but is performance-oriented:

But they started out at 6700 iirc and were recently bumped up to 7200.
(O/T) Also, it has an oil pressure gauge! How great is that?!

I hope its at least 7500

7500. The heads are suppose to be designed by Yamaha.

^Unfortunately, unless you have a source, that's entirely rumor for now.

I'd honestly be happy with a wider torque band and less expensive motor, I don't see a good reason for it to be any more than 7000.

High revs are nice, but at the end of the day it adds cost and I'd rather it be strong from 3-7k than 4.5-8k haha.

its been confirmed that Yamaha will have a hand in the head design. (I mean its not a toyota sports car without them)

here a quick link but look around and you can find mentions of Yamaha in almost every bit of info that mentions the engine

I'm going to predict an 8K redline but power peaks out at 7,600.

sorry to dissappoint u guys but... look at this spy pic of the FT86's interior, you can see the 7K mark on the rev counter...in red :cry:

Could be true, however we aren't sure if that is the production gauges.

that pic is from the older subaru impreza with its end chopped off mule. not the current one seen on the nurburgring...

Thanks, guess I'm just keeping my hopes down with so much "information" being flung around...

i'm glad some of you got my "over 9000" reference. i really think it will be between 7500 and 8000. i've said it probably 10-15 times on here by now, but i hope it has torque characteristics like the k20 in the civic si.

I would like to see 7600, anything above that I currently have doubts on for the production engine.

Why are we talking Redline? the Rev limiter is where the fun ends ;)

2000 Celica, 7800rpm Redline.... 8350rpm Rev Limit :thumbup:

What Tq characteristics? To feel torqueless? That's a terrible wish upon any car for that matter.

WTF? If it does not rev till 8.000 RPM I am not getting this car. I want a naturally aspirated high revving engine. If redline is at 7.000 RPM, than give me a turbo. Or I may simply get the new Porsche Cayman S (988) if I find the cash.

I really hope you're trolling.

He is. Just read his post history if you want any idea.

was it you that hates the k20z3? haha, i've had this discussion before with someone on here. if you'll look at the torque curve for the k20z3, it's pretty darn flat. i've driven a few of the newer Si's, and i've never had a situation where 140 ft lbs across most of the rev range has been a problem. and yes, i know what torque is. my MR2 makes 250+ ft lbs to the wheels. :)

Here in Qatar, the NA subaru impreza (EJ204) is redlined at 7600rpm. This from models from 2006 till now :D

So I guess a performance FB20 would at least have a 7600rpm :)

Looks good on paper and sounds good in application. I like it. :happy0180:

Maybe, but the butt dyno tells me the Si in stock form is gutless. I was hellbent on getting one, got the financing done, found the one I wanted in stock online, went to test drive it and it just felt like a dog. Tried city, highway, on/off ramps and it felt like I was driving a Saturn (engine wise, the fit and finish was obviously much better). I couldn't wait to get out of that car when we got back. I hope the FR doesn't feel so gutless. It may have similar stats when its all said and done but I better be able to feel the car move.

kinda sounds odd but that gutless feeling is almost a characteristic of a flat curve. a flat tq curve will put you back in the seat smoothly unless its a boatload of tq. thats why i drive a speed protege. crap tune makes it feel like a beast dd but the miata feels dirt slow and its my fun car

That's when I went 2 blocks down the road and bought my first 350Z. :thumbup: I know, apples and oranges, but you can feel the dynamics in that car, right down to the shift knob. I hope the FR captures that, even if the engine itself isn't on the same level.

The amount of torque a car makes isn't a problem if the 6 speed is geared properly, which has been Toyota's problem in the past. Just look at the 2000 celica gt-s, horrible gearing :(

yeah, the first few gears were way too far apart.

Why? I have plenty of miles on 8000+ fuel cut cars.

:thanks:

+1

My current honda's 'long stroke' K24Z redlines at 7100rpm. My old honda's 'long stroke' B18C redlined at 8100rpm, and still had 200hp.

Redline aside, I don't want a car that I have to rev to 4000+ rpms every gear in daily driving. That's how the celica gt-s was for me and I did NOT enjoy it.

I'd love a high-revving car that you have to shift all the time . . . if it has a sweet gearbox. But I get what you're saying.

Honestly, it's the gearbox that worries me the most. Toyota makes horrible gearboxes.

Me, too. The ones on the Lotus cars are so bad, I think Lotus more or less gave up on them and will now make their own.

Maybe we'll get lucky. That interview with Tada said that, aside from being a flat-4, the engine would be all new. Maybe the gearbox will be new, too.

Yes...it has to be a special engine to match the special lightweight chassis and weight distribution.

Anything missing from the formula will result in "just another car"

Aisin can make a very nice trans. They make the S2000 transmission which is the best shifting manual trans I've even driven.
