Okay guys, I have a couple of questions on a motor for my 4.3 swap. I have a 95 4Runner with a 3.0 that went out. I found a 1990 4.3 with harness for a killer price, but here is the question. I want to keep this truck street legal, so what do the Colorado emmission refs look at when it gets inspected. Could I get a newer harness and ecm.

 

Im doing a 22re to 4.3 swap.

But in your case, 3.4 would be the easiest, and would be the closest looking to stock.

 

I can't help you with the Colorado emissions question but I love the 4.3 / 700r4 swap lots of low end torque and it may be easier than the 3.4 swap with the Advance Adapters swap kit.

 

3.4 is easy when you have a 3.0, lots of stuff just bolts in, as a matter of fact im pretty sure it requires NO major fabrication, if any.

 

Not sure if this helps...http://www.liftlaws.com/colorado_lift_laws.htm

 

Well I thought about the 3.4 swap but since my motor and tranny went out I figures I would go ahead and do the 4.3 swap. Personally I dont care much for the stock look. Sorry to all the Toyota die-hards. Thanks for the help.

 

see if you can get a hold of okiyota, he is in colorado somewhere and he had a friend do a 4.3. might be able to point you towards COlorado emissions laws or somethings

 

Well in that case, go for the 4.3 swap!

 

I am fairly new to all this wrenchin speak,but round these parts guys go to painless wiring and they have all sorts of stuff to help calm down the smog police at least from an electrical end.(might not hurt to check out there web sight)

 

I would love to spend money on the painless kit, but I have yet to find the tree with hundred dollar bills. I do know enough about the wiring to tackle that job to help keep money in the rebuild of the new motor and tranny.
