Jpet runs 7.50 x 16s on Bam Bam.
The one thing he has mentioned not liking is the larger lug size on the 7.50s, making for fewer total number of lugs and therefore fewer edges to grip over the total circumference of the tire. He has made up for that by cutting them with a hot knife in the pattern of a BFG Krawler.

Interesting about going to the 1503. Did Ken give you the numbers on turbo performance? Has he ran one before? There was a crate 1403 for sale local this spring that I though about. Was think using it with a T19 and 3.6 Rockeater Dana 18 with 5.38's.

I would really like to run a 35" tire and an NDT just looks so right but I also want the CJ-2A to perform well offroad as well! Maybe I need to go with a 35" Super Swamper tire instead, I just don't want a 12.5" wide tire, I would really like to keep to a narrow 10.5 tires if possible! I know there is a narrow Super Swamper as well, I think it's like 9". I need to go look all that up!
Yeah that is what we were calculating! I actually have a V1903 that I will probably be putting up for sale sometime soon. I would worry about the 1403 with no turbo, I think that is only like 23hp I believe. -Grant

Hey smfulle I was just looking there are two types of 900-16 tires, an 8-ply tire and a 12-ply tire, do you think the 8-ply tire would be flexible enough? Thanks Grant

Not sure. Like I said, limited experience and knowledge. I guess you could be the tester.  Bigger tires also need bigger horsepower. Just another thing to consider. The skinny swampers are pretty stiff as well. Check with Rick G. He has skinny tall Swampers that don’t flex much. |

Hey 2Aer's
I finally have a solid plan on my CJ-2A build, and yes I've changed what I was going to do with my 2A about 10 times now but I have the majority of the parts arriving this week and next. My question is should I archive this thread and start a new one since I'm radically changing how I'm doing my build? I would love everyone's input and feedback! Thanks Grant

Okay so here is the finalized build plan . . . for now  . Going with a new diesel engine combination of a Kubota D1503 Turbo Diesel with a Jeep AW4 automatic transmission. Also I found out that a Suzuki Samurai is almost identical to a CJ-2A frame so instead of building a frame from scratch, I went out a bought a 1988 Suzuki Samurai. I'm going to be using the frame, axles, suspension, steering, fuel system, and transfer case from the Samurai. The main goal is to build a very light and fuel efficient CJ-2A that handle anything I throw at it! Here is the break down of parts that will be used to finally get my CJ-2A built: Engine Kubota D1503 3 Cylinder Turbo Diesel Engine. Yes it's a 1.5L 3 cylinder turbo diesel. It's a TINY engine that doesn't weigh much and it's quiet as well. Currently the D1503 has 45HP/100ft-lbs torque. Only 18" inches long and 325lbs. With a water to air intercooler setup I will be able to push the engine closer to 65hp and around 130ft/lbs of torque. Transmission AW4 automatic out of a Jeep Cherokee. Getting a custom output nose cone built to take a slip yoke into it. The AW4 is only 25" long which makes it one of the most compact 4 speed automatics. Also they have the advantage of being dirt cheap as well. Transfer Case Suzuki Samurai divorced transfer case. I've got an upgrade case that has a 1.70 to 1 high range and a 6.5 to 1 low range so I will be able to crawl! This is one of those weird scenarios where the 1.70 to 1 high range is really going to help my D1503 turn my 32" tires. I will be able to drive 55mph at 2500rpm but I can cruise in town at 45mph at 2000rpm all day long. Axles Suzuki Samurai Axles with 3.73 gears, front is disc brakes with manual locking hubs, rears are drum breaks for now. Debating upgrading to rear disc brakes and upgrading the front locking hubs from the Aisin hubs to a set of Warn hubs to make the CJ-2A look more authentic. Suspension Going to be using a Samurai Suzuki kit that allows you to install Wrangle YJ leaf springs onto the Samurai Frame. This will allow me to have great articulation and help support the D1503 diesel engine and AW4 automatic transmission Tires This one I'm pretty proud of. I found a 32x9.50r15 tire that only weighs 36lbs called EFX MotoVader R/T. Compared to the 59lb 33x12.50r15 Mastercraft tires that are on the Samurai currently these are much lighter. These tires are actually designed for a UTV/ATV but are rated for 1200lbs each at 14PSI which is more than enough for my 2A. They are light and very flexible which should be great for off roading. Also I will be using my original CJ-2A wheels. I found out that both the Samurai and the CJ-2A have the same 5x5.5 bolt pattern which is really nice. Fuel System I'm going to attempt to run both the Samurai fuel tank and the CJ-2A fuel tank so I will have a 20 gallon fuel capacity in total. Not completely sure this will work yet but it's something I would like to be able to run. I'm sure I'm missing some details but I'm hoping to start working on the whole thing within the next week at most. It's going to be an odd build but I'm going for light, flexible and fuel efficient. I'll work on posting pictures later this week of all the parts I have, which is going to be a ton so fair warning! Let me know what you think! -Grant Edited by DieselJeepGuy47 - 08 Aug. 2019 at 2:37pm |

Yeah I'm really excited about it. I'll admit that I noticed today the new tires I got are not DOT approved, so I won't be able to drive it on the road but I can change that down the road. There are several DOT UTV tires available that are super light and flexible which I think will work great on our flat fender jeeps. So here is the 1988 Samurai I picked up, noticed the massive 33x12.50r15 tires on it. They weigh around 60lbs just for the tires and make steering a challenge!  And here are the new tires mounted on my original CJ-2A wheels. Not how much skinner they are compared to the above tires. Also MUCH easier to move around and lift!  I'm hopefully going to start taking apart the Samurai within the week. I can't wait to yank that body off and get my CJ-2A body set onto the frame! Thanks Grant

Nice tires. Are you worried about side-wall thickness?

Honestly no I'm not. These tires are rated at 1200lbs at 14psi and they are 8 ply tires as well. Also these tires are actually designed for the bigger four door UTV/ATV so they should be fairly well suited for my little CJ-2A Jeep! -Grant |

UPS came today with a bunch of parts but these seats are the ones I'm most excited about! I found these seats on Facebook of all places, but I can't get anyone to tell me what they are off of and I have found no marking or part numbers on them either. They are super small and light weight and they fold down as well which is very nice.
   Now first let me tell you I'm 6'5" so a CJ-2A is a tight fit to begin with! But I really feel like these seats are going to give me the most comfort for the small amount of space I have to work with in the tub! I also enjoy how they fold down flat as well. I've been debating making a waterproof canvas cover that I put on the CJ-2A when I'm towing it trails etc so I have less wind resistance on my trailer but also so I don't have to worry about the 2A getting wet if it were to rain where I'm traveling too! Let me know what you think! I'm really hoping to have my 2A at least moving under it's own power by late fall and ready for the trails by 2020! -Grant

Grant !
Good to know there is someone else out there that changes their mind as often as i might. On a good note, you can comfortably sit on the patio in those seats and admire your new Zuke. So, what do you think of your Matori diesel in your Liberty ? I ask because I have many times thought of slipping a Matori 2.8 cr TD into my '46 with trans and transfer-case too. Would the length be too great ? Had you considered a Matori swap and why would you decide against it ? thanks Len |

Hey Len, So here are my thoughts on my Liberty CRD. I love driving it and I love the way it tows. The fuel economy is outstanding, I can get close to 30mpg easily if I keep my foot out of it, 28mpg all day long. I think it's WAY too heavy and the complicated computer controlled engine makes it difficult to transplant into our flat fenders. Also it's way too long. Part of what makes the engine so good is the 5 speed automatic mated to it. It has the right gearing for the diesel engine. I really have a love/hate relationship with my Liberty. 95% of the time I love it, but in terms of ease of working on it myself, I really can't stand it. The engine is almost too big for the Liberty, you have to take so many components off just to get to what you are working on and when you get there, you have to be part contortionist to get said part off. I've seen this swap done in a TJ Wrangler where they used the entire wiring harness and everything and the length was tight for the TJ Wrangler which is a 96.8" so getting it crammed into our 80" wheelbase just doesn't seem feasible! I've actually considered swapping my Liberty drivetrain into a JKU Wrangler, in Europe the 2.8L diesel engine came in the JKUs, so I've considered sourcing motor mounts, wiring looms, and ECU from Europe to swap into a 3.8L Wrangler Unlimited four door. It would be so much easier to work on and would give the Wrangler the performance I would be looking for in a daily driver! The entire time I've owned my CJ-2A and my love of flat fender's from an early age has been how light and nimble they are off-road which is what I used to help me plan my 2A build! My goal has always to find a diesel engine that was lighter than the original Go-Devil! -Grant

Hey 2Aers,
SO I'm changing transmission . . . again. I'm collaborating with KubotaSwappers to develop a Kubota adapter to Ford 6R80 automatic transmission. I posted a video about it last night check it out! So the 6R80 is just a hair shorter than a Chevrolet TH350 3-speed automatic however the 6R80 is a 6-speed automatic with a deep first gear and two overdrive gears as well. So the currently plan is to have the Kubota D1503 3-cylinder turbo diesel mated to the Ford 6R80 6-speed automatic then connect that to the Suzuki Samurai transfer case which has a 1.41:1 high range and 2.27:1 low range through the 3.73 geared axles on the 32" ATV tires! I should be starting the build in the new 6 week and will hopefully have it running around January 2020! Let me know what you think!!! Thanks Grant
