Engine swap in California?
« on: Jun 28, 2018, 08:44:53 AM »
I recently moved to the Monterey, CA area from Oregon.  Before that, I was in Colorado.  My 1986 4runner (https://www.instagram.com/albinorhino4x4/) is a dream on the trails but I'm finding it a real struggle to keep up with traffic on the freeways between Salinas and Fresno.  I don't even want to think about trying to get down to the desert this fall.  My top speed is about 65mph on flat ground with a tail wind with the pedal mashed into the floor.  The little 22RE has served me very well but it is pretty tired and is going to need some significant work in the near future (especially to pass smog -- probably needs a new cat, needs a new muffler, might need new headers, has lots of leaks, blah blah blah.  Will need a new timing chain soon-ish.  At least the injectors are newer so I have that going for me, which is nice.).

I'm engine swap-curious.  Thinking about either a 3.4l or 2.7l swap.  I do have the 21 spline setup in my Marlin Crawler-supplied dual T-cases which I understand that I would have to upgrade to 23 splines to handle more horsepower/torque.

My main stumbling blocks are 1) understanding how to make an engine swap legal in California and 2) finding a shop that can do it.  While I used to do all of my own work, I no longer can because I have no garage or off-street parking.

I found a bunch of older posts on the forum here and other forums about engine swaps in California but I've come up empty finding anyone who has successfully done it in the last couple years.

So here are my n00b questions:

  • Should I swap my 22RE to something different or fix my 22RE?
  • Can I swap engines in California and comply with CARB?
  • Has anyone done a swap successfully recently and is there a thread on here discussing it?
  • What engine should I swap to?
  • Are there any other things I should be thinking about?  Maybe sell the 4runner and get a Taco to build?  (I Know Big Mike did it but how practical is it to put 35" or larger tires on a Taco and be able to do the Dusy trail w/o significant breakage?  Dusy is my benchmark because my mother wants me to take her on it in the next year or two.)

Thanks a bunch for answering my n00b questions!  :bowdown: :bowdown:

If you go with a 3rz you dont need to mess with the cases. Just put the 3rz bellhousing on your existing transmission. Tons of people have done 2/3rz swaps in California. Search the forum a little.

I've tried searching but my google-fu.  I haven't found anything from the last couple years of someone being successful with getting CARB to sign off on it.  It looks like up until about 2014 it was pretty common to do but I haven't seen much since then in my searches.

How many miles on engine?

Have you ever changed the timing chain?

It's possible with worn out timing chains for the chain to advance 2 teeth on the sprocket, advancing the cam and then you get a BIG loss of power (been there done that)

I did a 3rz swap in my 85 a couple years ago and passed, a buddy of mine passed with a 3.4 last year so yes it's possible. it's best to find a donor vehicle so you can get all the necessary parts and the donor vin#. the 2rz/3rz is the easiest swap if you're coming from a 22re. no need to upgrade case splines

I have a 4.3 v6 that's ca legal this is what you need to know 1 the donor motor has to be the same year or newer 2 youll need all the smog equipment off the donor motor 3 the easiest is find out who your local referee is and tell that person what you want to swap in and he or she will give you all the info for what they are going to look for 4 once you know that whatever shop you decide on hand them that info 5 have fun
