Has anybody done a conversion with Toyota in a yj, or would it be easy a Chevy.

If Toyota what kind of engine, tranny and tc do I have to buy?

If chevy, what kind of engine , tranny and tc?

Not much money though.
 
Chevy is an easy swap, but any conversion is expensive. It's the small stuff that adds up. Once you source and engine (bone yard 350 w/ 3 wire FI) then select the trans and adapt your transfer (Novak Adapters), you need the following:
Block hugger headers
Cross Flow Radiator
Drive shafts
Motor mounts
Accessory pulleys
Power steering
Wiring Harness
O2 Sensors
Cats and exhaust
Fuel Cell
High pressure fuel pump and regulator
Oil, lube, Trans fluid, etc
Fuel line
Trans lines
Cooling fans - electric or mechanical

If you want to cut cost you can go with a first gen Chevy Small Block and throw throttle body injection on it or leave it carbureted. But carbs suck off road compared to FI.
 
What kind of Toyota motor are we talking about? A older 22r or 22re or one of the new 5.7 V8's that come in a newer tundra?
 
USMCvet is correct, unless you have a lot of the components already it can get really expensive starting from scratch on a 4x4, if you have some of the components then that should drive the decision on which way to go, of course you might have deep pockets, I don't know.

What year/motor? Did you blow up the other motor?
 
22r or 22re.

And yea, that's why I don't want to go Chevy, + everyone goes Chevy, I want to try something different.
 
No. My 4 bangers is still running, but I want more power. I wonder what other engine can I use with the same tranny and tc that the 94 YJ brings, It's a 2.5 stock.

Go find a 4.0 from a wrecked jeep. Way more power than the 4 cylinder. Just realize extra power can cause broken parts. Well, its a combination of hp and your foot.
 
Ok. Then I would need everything, my foot is always hungry for speeding. It's my first jeep, I guess I'll have to learn how to control my foot. I used to drive over 100mph in my other car.
 
The dana 30 and 35 under your jeep arent known for their strength. If you get a 4.0 you will also need a new transmission. The ax5 in your jeep wont cut it. You'll need an ax15 or nv3550. You'll end up with dana 44 axles. Basically you are asking for a sink hole for your checking account. If it bugs you that bad, sell your jeep, take some of the money you would spend on repowering and find a tj rubicon.

Just my opinion. If you wonder why I say this.

I sold her three days ago at a huge loss, I'm still sad. At least my jkur is in the garage.
 
If you want more power you can't just drop in an engine and adapt it to the existing trans or major problems are ahead. Your TJ is set up with a 2.5 and even if you go with a 4.0 you still have to swap in a trans at a minimum and a radiator, exhaust, accessories and the like. It's still a bit of a pricy proposition but well worth it.
