Another 700r4, plus a turbo addition

[Iceman3005]

Started working on it again.

Got the turbo oil lines finished up, the new fender in, and the battery trays made along with the new batteries installed.

Finished getting the trans and transfer case in today, installed rear drive shaft. topped off the fluids, started the truck and ran it through the gears. seems to shift good. Won't know really how well it shifts until I get it of jack stands and going down the road. Still have more things to get done. Need to finishing bleeding brakes, install front drive shaft, finish exhaust crossover, wiring for torque convertor lock-up, and then run the exhaust from the turbo.

I will probably to a 1 inch body lift to help clear the exhaust, and possibly a suspension lift.

I thought a body lift and raised mother and trans mounts would help a lot where the crossover needs to clear the frame. Oval pipe would do it slick too.

The crossover fits well directly under the converter inspection cover. The downpipe is quite tight however if you're going between the engine and frame.

Getting close ti being done, got the crossover welded up, all thats left is exhuast from turbo back. Took it for a test drive, wow what a difference! Actually will be a joy to drive!

Got the 3 inch stainless exhaust kit in today, also got the borgenson steering shaft in as well. Going to do a 3 inch body lift, that is on its way. Decided to go 3 inch just to make it that much easier to get this exhaust installed. Plus with the body lift, there may be a 40 inch tire in the near future going under the truck. Might be a 22.5 super single? Stay tuned to find out!

Got the borgenson steering shaft installed. 3 inch body lift installed. Stainless exhaust getting fab up. A few other odds and ends to do, then should be back on the road! Front drive shaft is really close to exhaust crossover. So a suspension lift will be next.

This is part of the project I'm really excited about. Scored a factory cruise control harness!

Got the fan shroud plate on, finished lengthening all the fuel lines, and fill neck for the fuel tank. Worked on the cruise control a little bit. Then finish the exhaust.

Exhaust is getting done! Found a hole in the radiator, so pulled to get repaired.

Close, just need to order hangers and finish the tail pipe!

What size is your piping? Was the downpipe custom made? Looks like you have a lot of clearance between the frame/ cab/ exhaust crossover.

 

[Iceman3005]

I did a 3 inch body lift, there wasn't enough clearance between the frame and cab for the exhaust. Yes the exhaust is a custom 3 inch from the turbo all the way back.

Ah, that makes total sense now. Ha ha. That’s why you had so much space there!

 

[Iceman3005]

Well basically I have this project done. Well kinda, the trans I installed is slipping in 2nd and 3rd gear so another trans swap is necessary. The trans was free so not really out much, just my time. Also the turbo is not spooling like it should, it had over 200,000 miles on it so not surprised but that was pretty much free also. The exhaust has a few minor things, nothing major. Tires are junk so I just ordered some new ones, next will be to tackle the rust and new paint.

Well, the 700r4 failed miserably! Pump died, 4th, 3rd, and 2nd failed. So I upgraded to the 4L80E. To much power with the turbo and the injection pump turned up.

Nice. That’s a much stronger transmission, and now you have more tuning ability that you probably will ever need. Ha ha

 

[True Knight]

Also, let us know what you think of the new trans controller. The technology has come a long way since I did mine in 2011.

The DSL-1 looks like it’s been upgraded quite a bit since then too.

I rebuild 700r4's to handle extremely high HP numbers, but to get it to handle the torque I am putting out would have required almost $3000 dollars. Getting tired of the 700r4. The 4l80e can handle 800 ft lbs of torque with no modifications. with a few mods it can handle well over 1000 ft. lbs. of torque.

So the 4l80e I basically got for free, the tci controller was about $800, $100 in fluids, $300 to lengthen, shorten drive shafts, $150 for the transmission / transfer case adapter, about another $300 in tach, wiring, and other misc. things. So total was $1650.

If I had to get a used 4l80e they go for any where between $500-800, so it still would be cheaper to go with the 4l80e upgrade. Rebuilding a 4l80e should only cost about $2000 with a new torque convertor, at my cost. Plan on another $500-1000 if you have to pay someone to do the labor.
