Cuz it's boxer engine, so it's gonna be hard to figure all out to fit SC in there. Oh it's possible, just a lot of for engineer ppl

as far as turbo'd n/a engines, it's alllll in the tuning (well, mostly). you could run 5psi and blow your ring lands to pieces, or you could 10psi and have a safe, reliable engine. tuning, fuel, and maintenance.

Ehh... yeah, the tune is key, but there are mechanical limits to how great cylinder pressures can be before something gives. You can break a piston even on a perfect tune.

Turbo motors just tend to have beefier internals to withstand the greater pressures exerted on everything.

Now of course, throw some detonation in there and everything from a melted piston crown to a broken rod and cracked block can happen. Even a stout motor can be destroyed in short order with a poor tune.

I'm really hoping that TRD does the R&D for me so I know what the limits are.

On a related note, in a recent interview, Tada, Toyota's chief engineer for the project, claimed 230 bhp was do-able.

If 230 is Toyota's upper target, then perhaps another 10-20% more power could be made before something breaks, given that OEM's tend to stay well below the mechanical limits of an engine.

I am already planning a 2.7 stroked built motor, with big turbo.
My current car is an STI with built 2.35 stroked motor, w/ GT35R turbo.

2.7 liter...that sounds like a Crawford Performance clone.

Hachi Roku n/a guys, do you have something against anti-lag? If you want crisp on/off throttle response AND turbo power...anti-lag might be the ticket.

Detonation: Hrmmm...what kind of modern fuel injection works really well on turbo engines and allows detonation to be controlled? (Clue: Subaru cars have the turbos, Toyota has direct injection technology.) The engine can't detonate if it doesn't have any gasoline in the cylinder yet.

I'm shocked that nobody brought up dry sump lubrication in this thread yet. The FT86 is pretty low.

Anti-lag ain't cheap.

[mojo jojo]

hhmmmm... direct injection twin charge a viable option? VW just did it with their hybrid Toureg

That's not always true. I'm not sure bout US, but in Japan it's pretty much do with how turbo & ECU is set up, so it comes out to be fairly cheap... At the same time my cousin told me that his friend did it to friend's Evo (I think it was Evo VI), he had to pay double of money, due to engine blow, after 6 month. So he had to rebuild it from ground up and took it off the anti-lag.
He said that it was nice response, but at the same time, didn't feel much difference in mid to high range response.

Or just an N/A free-revving peppy engine with pretty much instant throttle response, like the 4A-GE.

Turbos need not apply, could care less really. Its more about the weight, size, and engine response.

in North America anyway, I don't know of too many built up Subies with anti-lag. Can't speak for Evos.

sounds like a great way to turn your engine into mush... what's the longevity of a turbo'd engine with anti-lag?

[TRDMAN]

when you say toyota 1gr are you talkin about the 1GR-FE in the tacoma? that engine is big a hell but its got good power.

[NESW20]

anti-lag will drastically reduce the life span of a turbo. not ideal if you're going to be offering a warranty on a new car.

I predict that if someone has a turbo'd FT-86, they really shouldn't be worrying about a warranty anymore anyways.

A nice roots blower would make the car feel like it just has a larger displacement engine. No lag and a nice flat torque curve. That's what I want, but I certainly won't turn down a turbo or even a centrifugal blower if TRD offers one to save me the headache of R&D.
