Anyone have weight as well as power and torque figures for a 22R?

I am building a buggy and I want to keep it light.

Also, I am not familiar with the Yota EFI system. Is it easy to swap into something like a buggy? Just an O2 sensor or what?
And how much more power will the EFI really net me? Worth the extra expense?

Power and torque figures for a 22R?

<font color="yellow">About 110-120 Hp and 140 lb. Ft. of torque. But that's off the showroom floor or fresh rebuild.</font>

<font color="yellow">It's a lot more than just an O2 sensor. There's a mass air sensor, knock sensor, throttle position sensor, the ECU (computer). and so on... You will need the whole wiring harness for the engine, and a lot of time. It's not HARD. It's TIME CONSUMING.</font>

And how much more power will the EFI really net me? Worth the extra expense?

<font color="yellow">That depends. Anything you will use a rock buggy for (or even a sandrail) will likely involve serious off-camber angles. Toyota carbs (while better than some others) hate being off-camber as much as any carb. I love that I can stop my truck on a 45-degree angle in the middle of the winter for five minutes to watch a buddy try and make the mudhole I just went through, and count on my EFI to kick over every time. Fuel injection isn't a power issue, it's a driveability issue. I don't think there is an excuse to run a carb on a vehicle that didn't come with it - not if you're going to offroad it in hilly areas, anyway.

As far as horsepower, you can get HP from a carb on a built engine far more cheaply since you don't have to worrry about injector and overbore throttle-bodies and such, but what good does that do if the engine won't run when you leave pavement <IMG SRC="smilies/question.gif" border="0">

i hate carbs.

ever since my first one i have hated them. they don't start and get screwed up all the time. well mine did.

any way after the first time i have only had efi vehicles. no problems with it ever starting. except when i blew the turbo out of my saab.

the swap is pretty staight forwrd from what i've read. you might just try to find a totaled pickup or celica w/ a 22re. then all you'd have to do is wled it in. <IMG SRC="smilies/usa.gif" border="0">
