Even if its not efficient around the HP range, the tQ is there. Hondas make hp, Toyota makes tq. Thats what it has watered down to over the years. Toyota is capable of making a decent power with a small displacement. The celica was 1.8 I believe and making around 180+

 

Yes that is true, and will most likely always be cause of how vtec engages. But I still personally think that the tC was made to look good, not necessarily perform.

 

Good point man.

But the K is tourque defficient and has very high compression. 2 specifications I personally shy away from.

 

Oh how I wish I could afford to swap or even turbo my Civic.

 

2.7 sub 200hp motor is horrendous, 2.7 is out of bounds for a 4-cylinder motor anyway, it should certainly be bumped up to 6 with that type of displacement. At least the tq will be very close to the hp but still sub 200 for both. The tC was never designed to be a performance car, more of something that's all show and no go...it will remain all show and no go.

I don't see the 1AR being as efficient as the 2AZ for boost, the compression is actually increasing instead of decreasing from 9.4:1 (2AZ) to 10:1 (1AR).

 

tC was designed for aftermarket support. Its not fast bone stock but with aftermarket support, which it has plenty, it can be amazing fast.

 

Nah, I'd say that 300hp on a SOHC is pretty fast.
But I'm also a Honda person.

 

It's 9.8:1 (2AZ). 9.6:1 on mine since I'm an 06.

 

Correct you are, my memory < looking it up

Still the idea is to lower compression not increase it.

 

Agreed

 

The tC (2AZ) was NEVER designed for power, just because support is there does not mean it is safe.

It doesn't take much lurking around to find various threads that clearly depict that it isn't for power. Toyota with their failure of the SC shows it wasn't intended to make power.

The platform simply isn't made for it, platforms that are can handle slight detonation with no problems, the 2AZ cannot.

The tC is meant to be all show, that's what is meant by tuner. This is evident when Scion introduced the Spec tC, it had a solid glass roof in case someone wanted to add a carbon fiber roof; it had cheaper seats, in case someone wanted to swap seat; cheaper steering wheel so it can be swapped; cheaper wheels so they can be upgraded, you see it still came with the same motor and transmission though right, because it wasn't meant to be changed, there was no option for it come come motor-less.

It isn't to say there aren't some heavily modified tC's out there, Scion sponsors some of them, PTUNING, Dezod, Descendant, etc have some out there as well but they're in a position to handle scenarios when something goes wrong. The run of the mill tC owner cannot fork over the money for a new motor when a rod is thrown clear through the hood.

Don @ Dezod synopsis of the 2AZ:

Inevitably, the rule of thumb, to ****** a line for the Notorious BIG, "Mo power, Mo problems", this is especially the case with the tC. Someone can do everything right, as far as forced induction is concerned and take the car to be tuned by the god of tuning and still walk outside to a blown head gasket.

Just look at the Toyota lineup that uses this motor, it isn't meant for power at all. It's meant to get you from point A to point B safely and reliably, not quickly.

 

my tC was designed for power...lulz

 

1200whp FTW lol

 

yellow gold? you monitor must be off cause this "cement" doesnt look any yellow/gold on my monitor.

 

lol maybe your monitor is broken

 

no, but it is calibrated for design and print, lol

looks more like a slate grey, maybe with a small tinge of bronze if anything is there.

 

wat

 

tC with too much power is a torque steer monster of death! - I know.

 

lol.

 

I don't know why the continual speculation and dreaming... you'll all know what it is later this week.
