350 to 6.2 swap Qs...school me

[FRIZZLEFRY]

So I have had the diesel bug before

And after hitting the Rubicon with some Cummins 4BT powered rigs,and a friend picking up a CUCV with plans to ditch the 6.2,I could have the oppertunity to scratch my itch.

I have done some searchin n readin and re readin some PMs to tRusty from 2005 and just wanted to make sure I know what I think I know .

I have not committed to buying it yet,but I need to do my research so that I can make my decision.

So what Im looking for is what I need to do this swap,what I need off of the donor truck,and what I need to look at once I get the 6.2 prior to install.It is said to run but I most likley will not see it run in person if I do go pick it up.

What I have now is a 350/465 and hydroboost.

What I will need is the 6.2 with all the accessories on the front of the motor,a flywheel for the 6.2,the fuel filter thingy on the firewall,glow plug relay,and run 12v to a fuel solenoid thingamabob to make it run.

And what I can think of that I need to look at before install are the glow plugs and harmonic balancer.

Am I missin anything?

I dont really need a new motor cuz my 300k++ mile 350 rocks.But the idea of a stupid simple,mechanically injected,rattly,stinky powerplant is somewhat appealing

Help a Toyota guy out

Diesel rad, hydro boost brakes, second battery and tray...I think you covered most everything else.

If you can't hear it run first, by all means pull a few glow plugs to make sure they're not mushroomed. Check the oil, it should be black as coal even it had just been changed. The main thing to check of course is for antifreeze. Balancer, you're looking for cracked rubber, chunks of rubber missing etc etc.

There is a fair amount of good info you could read through in the diesel forum here. Quite a bit more active in there the last few years now.

You will love the diesel with the SM465 off road. I wheeled that combo in Moab and was completely astounded at how elegantly I could crawl that thing. The 6.2 is governed at both ends. Top rpm and idle. If you are in gear at idle and try to pull it down with the brakes it'll just add a little fuel. Basically if you have traction, it'll crawl anything at idle.

Welcome to the dark (black oil) side!

Haha!Thanks for the reply Rene I was gonna reply back to the 2005 PMs I still have of yours but I cant right now

I cant really use the radiator out of the CUCV as I am limited by the opening on my Toyota.The 22"x19" big two core aluminum rad I am running is pretty much the size of the opening in the bodywork.

The only thing I can really improve in my cooling system is to build a shroud.Maybe a fat oil cooler on top of that to help out?

So how much hotter does a 6.2 run than a gas small block?

Dont welcome me yet.I still gotta see what he wants for it

 

[AJMBLAZER]

Not much hopefully...because they all suck and are based off of the old Oldsmobile engine and they break and they have no power and they suck...


Remind him that it sucks...

Well, the good news is it'll run way cooler when crawling. At or near idle they use very little fuel...which makes them run cold. My K5 that didn't have a T-stat used to drop down to under 150F if it idled for more than a few minutes, even on the hottest days.

Where they do get warm is when you pour the coals to it for an extended time...like a long up hill section. More fuel = more heat. If it's just a trail beast you'll likely be just fine. Maybe a couple of good electric fans? Oil cooler will definitely help as the 6.2 is already set-up to use one.

Wait this thing is going in a 'yota? I was gonna suggest a cummins swap but that would be sick.

Does the yota have electric fans? If not I'm sure you could throw a flex fan on there.... those things suck some power but, man do they move some air. I'm sure theres something you could do for electric fans also... maybe figure out a way to send some more power to em.

you'll need a diesel flywheel, depending what tranny it's attached to now.

i just wanna throw in my two cents on how awesome a 6.2 powered toyota is.

as to the engine sucking..... i have been a proponent of the 6.2 since i bought my M1009. Not quite on par with a 4BT but a helluva lot lighter. and tis a V8. They have potential, visit marinediesel.com to see their "tigershark" which is a 400hp marine version of the 6.2/6.5 family. I think it puts out around 700lbft of torque as well. wouldnt imagine the fuel economy is great, but the lifespan of the engine would still have to be decent for a marine application.

Me, like having my 6.2 engine that will let me drive around the world a few times, getting great mileage, even if i am a bit slower than most and like rene said, as a trail rig, with a manual, the thing will climb trees.
