i'm looking to get some inforamtion on doing a engine swap 3.0 to 3.4. i have a 90 4runner with the 3.0 in it with auto. the motor i have is out of a 96 or 97 truck that was a manual. looking to keep it a auto. just have question on what i should do and so information on it cause i'm lost

 

First welcome

second Search. Youll find typing that ? into the search bar in the top right corner of the page you will find more info that your ever gonna need Try that also search the forum as there is an entire section dedicated to lifts, motor swaps and the most misc stuff you could imagine. Try that first and if you have a more specific question after... lets hear it.

Welcome again and good luck with it

 

ok thanks i really don't have a whole lot of money to do this

 

thanks

i got the motor from a friend that they had sitting there for cheap

 

Yeah money is always the kicker. Save your money (that motor too if its yours now) and wait till your truck needs it. That and research the crap out of the swap you want so you can do it when it comes time too. Nothing like saving money and taking pride in your own work (its not rocket sience just time and that $$$). Lots of info here and the web on all types of swaps. Take your time and dont rush or youll make folish and dumb mistakes (take it from me )

 

yeah the motor is mine now i got it for 600 dollars with the wiring harness and payed 200 for the rest of the stuff that he thinks i need.

 

Good deal on a 3.4 hope you got the comp too??? Another place to check out on the web is Offroad Solutions tho they are no longer in buisness they have great info and lists of whats needed still on there web site. check em out if youve never before.

 

ya i got the comp too. my friends work for a wrecking yard in spokane and they take care of me. they told me to try this swap in my 2 door 4runner.
i look on there web site and it help a little but not much. i was looking for someone that had got the same stuff that i did and has info on what they did

 

If you want to keep it auto then I would sell that engine and buy an auto. You will create way to much work for yourself. And yes it does cost a bit. Save lots O money. Just my opinion and there is bunches of info. Here is some links to get you started. Best of luck.

does anyone know about what year of wiring harness to use. i found a 96 and 97 auto

 

You would want to use the wiring from the 96 or 97 (same as the engine you have) and then make sure it matches the transmission. So wiring from a manual. Now if you go on TIS and download the diagrams you will see there are slight differences in wiring from each of the years. I don't know specifically for your years. My 2001 engine harness doesn't match what they have and I would frown upon making more work for myself. My opinion.

 

ok thanks i think i just might get them both to have and choose from
