Help ford people

[Dinkbuster]

Want to turbocharge a new to me ford 8700, the tractor gas 12k hours on it so will be getting an overhaul too, question is can I purchase a 9700 ford overhaul kit to make to engine turbo charger ready? I’m bombarded with information, it sound like bolting on a turbo isnt the answer so would the 9700 overhaul kit bring my 8700 engine up to par for a turbo? If that makes sense

Why do you want to turbo the 8700? If you're determined to have a 9700 engine with a turbo, the best way to make that happen is to go buy a 9700 tractor.

Sure, you can add a turbo, guys on this forum have done that on various tractors, but like you are finding out, there is more involved than just adding one. Are you wanting to do this just to have the experience of doing it? Are you just wanting the little extra hp? Do you actually need the extra hp?

None of your concern, thanks for the help

Do you need the extra practice typing, while offering no help? Do you actually need the practice typing?

Seemed like a valid question and comment

Why don't you give this guy's videos a watch:

FWIW Tractordata says the static compression ratio is higher in the 8700. 9700 kit
is turbo friendly but what other engine features does 9700 have ? Your question and
usual opinionated responses(sigh) are similar to people wanting to turbo a 966/986.
Extra power is extra heat,how is that going to be dealt with ? Otherwise,go for it.
What cool story ever started with " we wanted more power but just rebuilt it to stock
specifications" ?

Wasnt a valid question or comment, I didn’t ask if anyone thought I needed more power I simply asked how to do something, then to suggest I go and buy a completely different tractor was asinine

We just see it differently, its all good

And its the way it is on forums. If we were standing around BS'ing about it you would get a respone or 2 just like it.Might need to lighten up a little bit.

I don’t know what Ford changed between the turbo and non turbo 401 6 cylinders, however I do know some of the main internal component changes they did to the 4 cylinder engines built during that time
The main difference is the pistons and rods
Non turbo pistons have 1 1/2” diameter wrist pins and straight cut rings, the rods are the standard diesel rod as used in all 3-4 cylinder engines at that time
Turbo pistons have 1 5/8” diameter wrist pins and use a tapered top ring
The rods have the larger pin diameter along with a oil feed hole up through the center of the rod to lubricate the pin as well as helping cool the bottom of the piston, due to this added oil hole in the rod a different rob bearing is used that has a hole through the shell to match
Other changes were exhaust valves of different materials to handle higher exhaust temps, the blocks are drilled for external oil cooler plumbing, the oil pump has a different part number so likely a higher volume for all the extra oil circulation
I don’t know if 401 6 cylinders are exact copies of the 4 cylinders with 2 more cylinders but the components I mentioned should be researched before any overhaul kits are ordered

A turbo can be added to a non turbo engine for a little extra power if needed on occasion, but for constant use such as tillage upgrading the engine to full turbo specs or replacing it with a 9700 engine is advised
