How did it come out?

Simple math: diesel swap will come out ahead in my version.
Operating cost per mile for gas engine is $3/13 mpg = $0.23.
Operating cost of mile per diesel engine is $3/30 mpg = $0.10
New gas engine cost + Price per gallon/mpg [gas version] = New diesel engine cost + Price per gallon/mpg [diesel version]
Ignore labor and other things for sake of simplicity.
$4500 + $0.23 (x) = $8000 + $0.10 (x), where x is miles driven to break even.
x= 26,923 miles break even. Come to think of it that not that many miles.
Skill.....
You where I got that from? Trying.
Seriously with YouTube university and the help from knowledgeable club members and mud members all you really need to do is try. There's no rocket science behind it.
I'd never rebuilt an engine until I did my 1fz-fe. Seriously never. I followed the fsm (it's like a cookbook it become hard to f up if you just follow steps). If you do that then it's all just time.
Now We all value our time differently and I get that. So you have to figure out what you value your time at. Personally I find relaxation in wrenching. As long as it's not my bread winning job.


My dear old dad (who was a pro wrench) always said that mechanics are born and not made.
Hi Dan,If the R2.8 is CA legal and gets that economy I might have to spring for that swap. Cheeper than buying a new truck i guess! Also interest in a 1HZ swap. Valley Hybrids says its legal in CA......
Joey once told me, "We don't discuss mileage in this house."If you bought a landcruiser for fuel economy, you made a very big mistake. New vehicles of similar size and weight with gas V8 are getting mpg that's not enough of an improvement to use fuel economy as an excuse for an engine swap. It's my speculation that most people who cry about 1fz power and fuel economy could have there purposes fulfilled by a Chevy Tahoe. They already have a V8, get a little bit better mpg and can handle the roads most Americans will drive on anyway.
No swap is straight forward and will end up costing way more than you think.
My interest here is in why your engine runs poorly after a head gasket replacement?
@NLXTACY actually did that rebuild BECAUSE it was cheaper than a swap, which he felt was overpriced. If you can't afford the downtime, pull a junker and rebuild that as time/funds allow, then put it in. Dunno about the FE, but I'm gonna say you can't do a decent new-oem-parts rebuild of an FZ for $4500, much less turn a profit on it, even if you got the long block for free. So there's that.There is absolutely no chance in hell that a swap is cheaper than a rebuild. Nope. Even when you look at an insanely overdone, anal retentive Rebuild like @NLXTACY did you still couldn't get a decent quality swap for the money. If someone says they can do a swap for under $15k I would like to see multiple references and vehicles they have done.
