chevy 4.3L swap

runnerboy97 · 04-30-2007, 09:01 PM

i did a little searching couldnt find much info. a guy i work with has a 4.3 out of a boat, stand alone harness, would it be worth considering to swap into my 88 4runner, the 3.0 is about to die for the last time.

Do it, I have considered this swap many times. The power and torque you gain is a good reason to do it.

colsoncj · 04-30-2007, 09:43 PM

4.3s are a good swap, but im partial to a 302. however, cheap deals lead to engine swaps

so go for it

runnerboy97 · 05-01-2007, 05:53 AM

is there anything in particular i should look for in this engine that i would want to make sure i get from the donor source.

I'm an S-10 owner and visit this site a ton http://s10planet.com/forum/showthread.php?t=7561

That particular thread has some decent info on blocks n such. They'd be a real decent source of info for the 4.3 swap over there. Might be worth a snoop.
I considered stuffing a 4.3 in my '92 Toyota as well. May still be an idea.

Theres a little info on swaps in my FAQ page....

Heya John! I'm looking for a 4Runner to put my 4.3 into as well. I gotta vortec 4.3 with tranny and computer still in the van. Let me know what you find and maybe me and Philip can come up and help you if you decide to go this route.

Is there a difference in the marine applications?

Yes they are different, also I'm not so sure I would want to put a used marine engine in my vehicle. Marine engines even when properly maintained get pretty abused.

cootees · 05-01-2007, 12:43 PM

Jon, If you do decide to go this route PM mrgtstr on TTB. He is doing the 4.3 voretc swap in his 1st gen runner.

4runnerx3 · 05-01-2007, 03:38 PM

Make sure you know the rotation of the marine engine before you install it.

runnerboy97 · 05-01-2007, 09:24 PM

the engine is only a couple years old, came from a boat that fell off the trailer and was totaled, i know the guy so i know the history of the motor, maybe 25 or 30 hours on it.
thanks for all the info and good links, i've got some reading to do now before i make any further decisions.

Stomis · 05-02-2007, 08:27 PM

Hmmms 4.3 vs chevy 327/350... Same mileage but your going the path of less power...

runnerboy97 · 05-03-2007, 06:23 AM

my thought is anything is better than a half dead 3.0, price is also driving this. i can probably get the 4.3 for really cheap, in exchange for some work.

callmej75 · 05-03-2007, 06:26 AM

I would also check that rotation thing John...if there is a difference there then that may throw you into some obstacles that would be unnecessary. I don't blame ya for ditching the 3.0...

4runnerchevy · 06-02-2007, 05:09 AM

This kind of swap was made for a Toy. I have done 2 and am on my third for a friend. I highly recomend it. I had to deal with Cali smog laws so it was important to get all the smog parts from the donor as well as the usual wiring and ECU. Good Luck !

90inworks · 06-03-2007, 12:49 AM

how much would a 302 swap cost i wouldnt mind doing it for my senior prodject

HA try again, the 4.3 will give you better gas! its probably because of less power though

Not as much an urge to just goose it.
