New CJ3a build

Well I've been doing alot of research and have come up with a basis for my build. I'd like a little input on this to see what everyone thinks. First thing is I'm trying to build this relativity on the economical side and for practical purpose's. So here's what I'm thinking (or have started): The stock flathead is getting replaced with a 96 ford ranger 2.3 engine that I plan on putting a turbo on. The T-90 will stay and a Dana 20 will replace the Dana 18. I'm using A dana 44 rear axle and a dana 30 front axle with disk brakes, I plan on locking the rear and running 4.88 gears. I'm using the steering column out of a 76 cj5 to complete the power steering conversion. This will all sit on a CJ7 4" lift that will remain under the axles. So far this is all I have planned besides a full roll cage, does anyone have any input to offer on this build, any help would be greatly appreciated.

I've done a 225 buick swap in a 1959 willys cj5 and was looking to go another route that was almost as simple as that so this looked like the route to go. Original plan was to put a 302 in the jeep but i dont want to do all the work that is involved with that swap.

I buddy of mine did a stock 2.3 to 2.3 or 2.5 turbo using a thunderbird s/c turbo. Roughly 200ish horsepower. Runs really well. Its more or less an injected updated pinto motor. Pinto motor swaps used to be very popular into flatties.

Well the motor im putting in it makes 115hp and 135 ft/pounds of torque which is roughly double the hp of the old flathead and about 30 ft/pounds of torque more not a huge difference between stock but the fuel injection will make it much more reliable and efficient i hope.
On the other hand will the stock gears from my Dana 44 in the willys work in a newer dana 44 axle. Just wondering if I can use the stock ring and pinion and avoid having to buy a whole new setup unless its really worn out.

Hey nice to see another Vermonter on here, I'm located in Wilmington. So your going to install a Inline 6 into your willys, I really like inline motors I have a 1982 F-150 with a 300 inline 6 and its a great motor. Well right now the motor im using is a non turbo motor but there are alot of parts out there to turn these little motors into monsters from what I read. I mean i've seen turbo kits for them for $700 and I need to go through the motor anyways, so i'll need low comp pistons and stuff along those lines but to get 200hp out of a 4 cylinder would be fun. I'm also not a huge fan of the oddfire motor not that its not a great conversion for these jeeps but its such a ratty running motor I never really liked how it ran even tuned in.

do what you want, in the end its your rig. its all in how you are going to use and drive it. i always thought no way would i have a 3 speed, just finished working on a customers 77 CJ5 and thought, hell the 3 speed isnt that bad. not everyone is looking to build a mountain stomping, 800hp handling rig that'll do 100 down the interstate. do your research first, double your target budget there's always something else you'll want and need when you get to building it. the T90 is just a pain in the ass with all those fucking roller bearings but can be tore down and rebuilt real easy.

use novak for anything you need to adapt. their stuff just makes projects go that easier.

I really dont want to use the T-90 tranny but its looking like the only option for this swap due to thats the only adapter available. I have a t-150 sitting in my garage that i'd rather use. Oh well I guess

I think the 2.3-2.5 'pinto' style engine would be great in a flatty....

If you looking for more transmission options you might check into the Canfield Industries bellhousing adapter plate. It converts the bellhousing pattern the small block ford pattern.

www.cididit.com

That will let you do a LOT of different transmissions. Being a flatty, I would try and get the shortest trans/t-case combo I could. Novak makes an np435 to D18/20 adapter now I think....

Good luck with your project.

Ill have to look into that cause that would make things much easier for me. Has anyone done this swap on this site and if so how did it go in terms of flywheel starter pressure plate and clutch disk???

Advance adapters has a guide on this stuff. Used to give you all the dimensions, spline sizes of clutches, everything you need. I think if you dig around on their website it might still be there. Novak has lots of info. You can call them, great to deal with.
The Pinto engine was a popular swap for a flatty. And a T150 I believe will bolt right up to a Ford?

I would think that you could use that T90 adapter bellhousing with a (rare) early CJ T98 that came behind an F-head or some of the other conversion options for the L134 (This setup uses the stock bellhousing and adapts the 4speed behind it). I believe that both Herm the overdrive guy and Novak have swap kits/parts for adapting the T98 and NP435 to the L/F134.

http://hermtheoverdriveguy.com/id41.htm

http://www.novak-adapt.com/catalog/kit_1435.htm

*edit* never mind, I looked at the novak adapter setup to the ford motor and I don't think this will work--it replaces the input shaft bearing retainer on the transmission making it T90 specific...

I guess i'll have to stay with the T-90. If I could find a T-90c that would at least give me a little better low gears. I've also contemplated putting a c-4 behind the 2.3 with the dana 20 but I dont know if that will work.

Well picked up my motor yesterday and I'll have to say it seems like this little motor was build for a jeep. I will have to do very little modifications to the stock form to make this work. The only problem I had but solved was finding a 1974 ford pinto bell housing to make the adapter work. But once I get the motor rebuild and all other things in place I'll start to post some pics. Now my next question is should I stick with the stock gearing of 5.38 or go to a 4.88 gears im leaning towards stock cause of the T-90 first gear and only having a 2.46 low range.

I'd vote for stock gearing--and eventually try to find a used Warn OD.

Hey does anyone here know the best way to box a frame? The frame I have isnt in terrible shape and i'm not putting huge power in the thing but I'd like to get the frame a little more rigid is there a good way of doing this??? I really dont want to build a whole new frame due to the fact that the thing wont be a straight off road rig, and the frame I have isnt in bad shape

I'm fairly certain the ford 2.3 ( or your ranger motor ) used a smaller flywheel than the SBF stuff. I also think the 2.3 crank bolt pattern is specific to the motor. I don't think there is room in the 2.3/2.5 bellhousing for a larger flywheel. That is one of the reasons why the SBF adapter plate is so nice, you get to run a larger clutch and more common bellhousing.

this much I can tell you: the ford 302/5.0 use two different weight imbalanced flywheels--I think prior to '81 they were 28 oz imbalance and after that they are 50 oz imbalance---so is that engine internally or externally balanced??? they also come with different tooth patterns(157 and 164) and the starter needs to match.

do you still need that bolt pattern for the flywheel??
