Doing everything on your own, it could be done for as little as about a grand or as much as $3000. I would say typical prices for a complete engine + harness & ecu is around $650-$1000 for the older versions or around $1500 for a very low mileage 2003 or 2004 version like what Bevin has.
Bevin's 2003 motor only had 14,000 miles on it I believe, and Dean's 2004 motor only had 9,000 miles! They both spent nearly $2,000 for everything including the full exhaust, interior wiring, and fuel tank with all emissions equipment.
Then, once you have the engine, expect to budget about $500 for misc stuff like a Toyota wiring manual (STRONGLY recommend using a genuine Toyota wiring guide, full color pages!), fuel lines, clutch lines, radiator upgrade if needed, coolant hoses, welding, metal to build motor mounts and make brackets and such, fuel pump if you don't already have an EFI, two O2 sensors if you didn't get them with the engine, etcetera.... I know $500 for "miscellaneous" sounds really high, but trust me, if you've never done an engine swap before, you're gonna find out real quick like that all the little stuff really adds up. How about a clutch? If you got an automatic engine then you'll need to source a flywheel and clutch. I just want you to understand that doing an engine swap is a SERIOUS matter. My advise is to approach this with a serious full-on game plan. I picked up my 3RZ on July 4th, 2004 and took my truck to the inspection station in early October. So it took me roughly 3-1/2 months of working in the evenings to complete my conversion. Bevin got his engine in May of 2005, we started working on it in August, and we had it passed the state inspectors by July of 2006. So for him it was a full year investment. There were a lot of times where him and I wouldn't touch his truck for weeks at a time because we were so tired from all the work. But if you stick with it, the rewards FAR OUT NUMBER the effort!!!!!! :thumbs: :thumbs: :thumbs: :thumbs:
Check this picture out from the last time I drove to Rubicon:
This is from my OBD-Diagnostics software I was using to monitor my fuel mileage during a 160-mile stretch along highway 99 in central California.
23 MILES PER GALLON ON 37" TIRES!!!! My average speed was 65 and I was not drafting behind anyone. Can a less-powerful 3.0-liter V6 get 23 MPG? I DON'T THINK SO!! HAHA I LOVE MY 3RZ!!!
As for my expenses, I didn't keep close track it but I estimate I did my whole swap including getting it passed the ultra strict California Emissions Inspection for around $1,500 for everything including the engine. I did my swap before the 3RZ became popular so I got a lot of good deals.
Good luck! You have to "want" something better than what you've got before you make the first step with an engine conversion. I know there are some reading this who are thinking, "ahhh BigMike is a rookie I've done 12 engine swaps and they were all cake". I am telling you straight how I feel an engine conversion should be looked at. It is my opinion that if you don't have the proper mindset, then you may get discouraged and stop half way and sell everything you've worked on. I've seen it happen over and over. It really is a lot of work and you will spend a good part of a year getting all of the loose bugs worked out before you can truly say it's done.
I am in no way an engine swap pro, but here is where I draw my experiences from:
First engine swap was a 1993 Toyota Levin 4A-GZE Supercharged engine into my 1987 Toyota MR2. I did this back in 2000 when I was 19 years old.
My 2nd swap was a 1989 Toyota MR2 4A-GZE Supercharged engine into a friends 1987 Toyota MR2. I did this sometime around 2002?
My 3rd swap was my 1995 3RZ into my 1981 Hilux back in 2004.
My 4th swap was a 1996 3RZ into Marlin's 1980 Hilux in 2005.
My 5th swap was a 2004 3RZ into Dean's Hilux also in 2005.
My 6th swap was a 2003 3RZ into Bevin's Hilux also in 2005.
