I'm having a hard time deciding on my next upgrade. I have a 22r with a webber carb, it runs great but I would like to get a little more out of that engine. Would it be better to make it a fuel injected or add supercharger w/the existing carburator?

 

If you want more power, things like a more aggressive cam and a header will give you that. If you want LOTS more power, do yourself a favor and swap that engine.

 

Yeah, to really get power, you just need to get rid of the 4 cylinder. They just don't have it. Low end torque, yeah, but highway power? You can spend a lot of money and only see minor improvements. My 86 22RE, which ran really well, with 200,000 miles, was not faster than my rebuilt 22R on my 83. That's with a slight performance cam and rebuilt carb.

 

20R head...

+ cam + header =


Run the 20R's timing cover and you get a dual-row chain.

I pulled mine out of a Corona at my local Pull-A-Part, did a no-no and bolted it right to a tall deck 22R I had and she's been rolling ever since.

I love it to death. It's got gobbs of high-end power (it's actually red-line limited) and I beat it like a rented mule daily.

...And I mean I flog the ever loving wee out of it

 

What do you want out of your truck? It can only give so much...

 

EFI or Carb, and how to modify it largely depends on what the truck was from the factory.

I think it's just too hard and complex, with not enough benefits to convert a cab.

Specially when each has their strong points, and drawbacks.

If I wanted EFI out of my carb truck, I'd just go buy a EFI cab or truck and start from there.


If it was a carb truck, as previously stated, I'd throw a 20R head and possibly cam and headers on it.

If it was EFI. I'd think long and hard about higher compression pistons.

They are just like adding a Turbo, only there are no more moving, complex and costly parts, and there is NO lag. (TMK) They instantly work with EFI and its knock sensor.

You just need to run high octane for the rest of its life...

The same thing you'd have to do if it had a Turbo.

 

Thanks for the information. Lots of good knowledge here. My main issue for wanting more power out of the engine is simple. The larger tires and the lift makes it hard for the truck to get up to highway speed(70+). As far as off-road, I can't ask for more because it does great.
An engine swap is not a immediate option, the engine that's in the yota has less than 8k miles. It has a cam/headers/dual chain/webber 32/36.
What would be better to its(highway) performance?

 

Maybe regear to match your tires better...

 

:CaptainObvious:

 

Yes, but this is what so many newer people miss. You put on bigger tires, and it's the gear ratio making your truck a dog. These engines just aren't big. They work on the gearing. Bigger tires means your gears aren't right anymore, so regearing is the best way to get your power back if you went with bigger tires. My truck is not a rock crawler. It's a DD and road trip vehicle, that also goes offroad. Because of that, I stick with 30x9.50's, so I don't need to worry about changing my gears. Once you're up to 31's, you really start noticing your power going away...
