200ci I6 and NP435, which bell housing?

[Prizefighter]

I want to drop my 3 speed and put in a NP435 behind my I6. Anybody running this? The tech article talks about V8, but I haven't found any info for doing this with the 200 I6. What bell housing would I need, will the one I have bolt up?

Also, I have a NP205 tcase sitting around that bolts to the NP435. Any thoughts about sticking with my D20, or running the NP205? I want to wheel this I6 beater hard.

My running Buddy put a NP435 in his Bronco it had a mustang 200cid . We used the stock 6 cyl bell housing. Some one else can answer the question about the 205 But I think it works fine just not sure.

Thanks Papitt. I thought I read somewhere that the stock bell housing would work.

3-speed bellhousing will work.

If the 205 bolts to the 435, it won't work with the 20. The 20 bolts to a 2wd 435 with the adapter.

You're right, my bad. I forgot to mention that I am in the process of trading for a 2WD version also, so both would be available.

X2 stock bronco bellhousing. tcase is up to you dont know how much longer a 205 setup is but consider that you will already have a longer setup even with a D20 you could be looking at a extra 5in of tranny/tcase compared to stock. Might hurt driveshaft angle if you have a large lift.

The 205 is beefier than the D20 but the 200 isn't going to break a D20. The D20 has better low range gearing than the 205 which you could probably use with the 200.

 

[bigjhoov]

The 20 setup is only an inch longer at best. Stock crossmember can be used, just redrill the hole. Swap driveshaft slip yokes from front to rear and you're good to go.

Thanks, I think I'll stick with the D20 and good to know it has lower gearing, need all the help I can get. I picked this Bronco up about a month ago, and it could win best beater award. I plan on beating the mess out of it having fun, and having it mechanically sound/solid by Sept.

With a 6cyl and NP 435 your set up is going to be several inches longer than stock. You'll need to do cross member and driveline modifications.

The 6cyl intermediate housing is shorter which accomodates the longer motor. However, when you put the longer transmission (NP 435) behind the longer 6cyl motor your overall length will be several inches longer than stock.

The reason you can use a 6cyl housing with a NP435 in an 8cyl is that the shorter intermediate housing offsets the longer transmission. No such gain with a 6cyl motor.

Since you have the 6-cylinder transfer case adapter off the old 3-speed, they make an adaptor plate to use that with the NP435 to mate to a D20. That would be prefered to the NP205 to me anyway.

The NP205 is a stupid strong transfer case. You pretty much have to do something really bad to hurt one. But it is way overkill for the 200. The D20 is lighter and has taken the abuse of high powered V8s for decades. While the D20 isn't as bulletproof as the NP205, it is highly bullet resistant (just don't use armor piercing and you will be fine)

i just swapped np435 to 205 transfer case in and a little over 3 inches longer than stock on the v8.

i just swapped np435 to 205 transfer case in and a little over 3 inches longer than stock on the v8.

So with the I6 it would be closer to 6" longer. All the more reason to keep the D20

 

[firefighter2134]

yeah. since i have no lift yet my rear shaft is only 30 inches long lol

I think you're mistaken if you're referring to the I6/D20 set-up. I've done three of these and they've all been just an inch or so longer than stock. N major mods needed.

If you're talking about the 205, you may be correct. I have no knowledge of that swap.

bigjhoov you seem fairly experienced at this exact swap so feel free to correct my fuzzy numbers. I believe the NP 435 is 1.5 to 2.0 inches longer than the stock 3 speed? The adapter plate between the NP 435 and the 6cyl housing is an extra inch itself.

 

[bigjhoov]

I can only speak for what I've experienced. These are pics from one of the swaps I did. It was an adapter that one of the vendor's sells that's made from a stock intermediate adapter. The other two used the aluminum adapter and the 6cyl intermediate adapter. I just drilled a new hole on the back of the crossmember mount and another hole on the front of the crossmember. Used four bolts instead of two. Should be twice as strong, right?;D
