1.8 to 2.4 only 30hp?

[Hatch]

Is it just me or does a 30hp gain w/ .6L gain seam like a really small gain for the increase in engine size?

Engine displacement rarely has anything to do with power output or torque. There are too many factors into play when it comes to producing power like the valve angle, aperture, size, timing etc. so you can have a small engine making lots of power or have a big one making average (for its size) power

[SmokingTires]

If you were talking overbore, maybe. But engines are designed entirely different (like he stated above).

Displacement doesn't matter once you get into head design, cam design, and all the other factors that go into the build of an engine.

just curious because with the new celica being rumored to have the 2.4 and the celica gts already running 180 after lift in the 1.8 i dont really see a benefit

Yeah well the 2.4 has something your engine does not. Torque.

[Piddy]

Ya... with the extra displacement you are going to gain the torque that the Celica is missing. If they still put VVTL-i on it... that would be pretty sweet ass... but i'm sure they won't... they like to not make us happy. Like discontinuing all of the decent RWD cars

[Hatch]

it only has 30lb/ft more torque - that could easily be gained with some simple cheap mods w/ the 1.8 - if they put the 'L' in the 2.4 that would be incredable - but you are right - what are the chances of that.

It would be interesting to see a GTS against a TC to see who would be faster in the 1/4, any ideas? my bet is the GTS because of the added boost at the top end.

Cheap mods would never get you 30 ft/lbs of torque. And even if you did get near that, it wouldn't be low-end torque, which is what the 2.4 has.

Yeah it's 30lb/fr more torque but if you look at the dyno graph you're in for a suprise.

So are you going to post it or what?

[EKam]

Well I haven't seen a 2AZ-FE dyno graph before, but I doubt it will be much differrent from the 1MZ-FE's since they both use FE heads and have relatively close displacements.

On the other hand 1ZZ's torque curve is flat across the rpm range and sits way below the hp line which keeps increasing as rpm goes higher.

[SmokingTires]

And what is the suprise we are in for then?

(And I hate that people keep saying lbs/ft. The term is foot pounds. ft/lbs)

[Pineapple]

Sorry its ft x lbs not ft / lbs or lbs / ft. Also ft x lb = lb x ft

[SmokingTires]

Actually, if you read any manual, it will say "ft. lbs." The slash just puts them together. Putting a "x" in there just makes it the equation form.

[Hatch]

So if they both use the FE head would you be able to retrofit the GE head on the 2.4?
