Thoughts and opinion?!?


I want to build this jeep as best as i can however i do have a budget i must keep in mind. Personally i think Steed speed is artwork and their price reflects it.

Antone have a used manifold they want to donate to the rolling coal foundation?

I had thought one time of putting a 4bt in an old CJ I had but decided to go a different route in jeeps. Maybe I will if/when this motor goes...hopefully a looooong time from now! Great build!

What transmission you gonna run behind it?

I am using the stock AX-15 for now. I plan on upgrading the transmission down the road, after my funds recuperate from the engine. There are guys out there running AX-15 with the cummins and have had no problems. I will try it until it proves me otherwise.

Finally the Cummins has made its way to my garage. Its overwhelming just how big and heavy the engine is.

Well i have gotten a lot done in the last week. First started off by getting the 4BT onto the engine stand. This wasnt easy by myself.

The first order of business was to ***** the engine and make sure it was exactly what i ordered. I am very happy with the overall engine. The only thing i dont like is a large dent in the oil pan which looks like a casualty of shipping..

This stock setup will push my down pipe into the firewall. My options are to cut and weld my firewall to make the down pipe fit, which i am not oppossed to, just takes longer.

My second option is to purchase a used 5.9 6BT manifold, cut off one port on each side and weld it shut. Then flip it and use it as a high centrr mount. I have no prices on used 6BT manifolds. There are plenty people who run this setup and have zero problems.

Third option is from a company called Steed speed performance. They are a Canadian company who cnc mills 4BT manifolds out of stainless. As yoy can imagine they are pricey. About 620 here are some pics of their manifolds

I finally decided to buy a 5.9 exhaust manifold and cut the two ends off and weld the ends shut. I talked to a friend of mine who is a welder and he explained how to weld cast. I did manifold with a mig even though i should have used tig. ( but i aint got one)

The first picture is showing my final ground weld on the rear port.

The entire piece above.

And the front weld ground smooth.

I am very happy with how it turned out. Hopefully no cracks!!!!

Next on the list was the turbo. I managed to break another bolt off.. This time the bolt is in the exhaust housing of the turbo. Awesome. I know right.. so. A simple job of clocking the turbo has now gotten more complicated.

The first picture shows the compressor side of the turbo removed and with the orginal paint..

The second and third show what a little paint stripper wire wheel and a lot of elbow grease will get you. I got the compressor side clocked but cannot get the exhaust side to move. I beat the sh*t out of it with a dead blow and i honestly dont think it budged..

I forgot to post the pictures of removing the stock exhaust manifold. Removing the old bolts was a pain. There are eight bolts and three bolts broke off in the head.

After grinding the broken pieces of bolts flat i center punched them and then drilled them out followed by a tap to clean the threads in the head.

After getting the manifold cut and welded and the cleaning out the old bolts i moved onto clocking the turbo. Since the engine was originally a low mount turbo i have to rotate the cold side and hot side of the turbo.

forumrunner_20120726_194003.jpg

You can see that the discharge port of the turbo is pointing down and need to be 90 degrees from where it is now..

So i was able to remove the cold side and rotate it properly. However the hot side which is the exhaust side is so heavily rusted i cant get it to budge.

I have tried penetrating oil for two days, light heat from a torch, smacking it with a dead blow and cant get anything. Anyone have any suggestions. This is one of the last things to sort before i can start taking the jeep apart.

I am currently soaking the turbo in a solution of Acetone and ATF mixed 50 / 50 . Anyone with ANY ideas would be much apperciated. I cant be the first person to have a rusted compressor housing.
