However, i do plan on eventually getting an overdrive unit for the TC which will give me a "5th" gear, at 0.75 ratio. this coupled with some big tires will allow me to keep the RPMs relatively low and still keep up on the highway. Im not sure if I want to splurge on the overdrive before I install everything, or later down the line. I am kind of thinking later on down the line after the patrol is up and running.


They say that engine rpm doesn't matter. It's all about how fast that output shaft is making the gears in the Spicer 18 turn. This is all independent of what your engine is doing and is solely based on how fast the vehicle is moving. Well...not solely...as bigger tires and alternate differential gearing could raise your top speed without effecting the transfer case. But anyway, I hope they're just being overly cautious. My feeling is...if you're on a smooth freeway, is the higher gear speed really going to be that damaging? I wager not. But anyway, I hope it goes well for you and I look forward to seeing your results when it's all said and done.

Oh okay I see what you're saying. Well yeah I'll just have to see what happens. It wont be driven on the highway all the time, and the Dana 18 is supposedly the best/strongest transfer case ever made! Haha

the transfer case has been rebuilt and is ready to go. this was MUCH easier than the transmission!

Image

I should be receiving my flywheel today. Once I have that, I can install it and the clutch, then the transmission, then the TC. Next step would be dropping into the patrol for test fitting!!

I got the flywheel in yesterday, which means I was able to get everything bolted together! I had to finesse the trans and TC a little bit with an angle grinder to get it to fit, very close together!

Image

Image

I also had to relocate the shift stick pin screw. You can see the original spot for the screw right behind one of the gussets in the transmission. so I stuck an old screw in there with some loc-tite, and drilled and tapped a new hole on the right side of the shift tower. this will make it much easier to access the screw to install and remove the shift stick pin.

I just ordered all my new brake parts for the patrol for my disc brake conversion. I will be using the following:

Front brakes:
1993 Toyota 4runner 3.0L calipers and pads
1993 Toyota 4runner 3.0L rotors

Rear brakes:
1993 Nissan 240sx calipers and pads
1995 Isuzu pickup rotors

I wanted to go with 240sx rear calipers because they are pretty cheap, easily found (at least when you are in the drifting community :) ), and have built in e-brake cable attachments. The Isuzu truck rotor is 0.1" thicker than the rotor on a 240sx, so hopefully the 240sx caliper/pad combo will still drop onto the rotor nicely. If not, I may have to turn down the rotors a bit.

The brake conversion will start once the drivetrain is complete and installed in the patrol. I want to get it running first, then I will do all the axle work (SPOA swap, disc brake conversion)

The post you have all been waiting for...THE ENGINE IS IN!!!

Image

Image

Image

I wanted to line up the shifter with the OEM shifter hole in the floor board cover piece, but I wasnt able to push the engine back any further due to exhaust manifold clearances. At least it left me with a bunch of room to work on stuff at the back of the engine if I ever need to!

Image

These are the exhaust manifold clearances I was talking about. The driver side manifold sits a little further back than passenger side, so it will probably be a super close fit. I think ill try to find a set of low profile block-hugger headers.

Image

Image

Even though I wasnt able to move the engine back any further, all the weight is still over or behind the front axle, so it will work for me!

Congratulations! :clap: :clap: :clap:

You move fast, since I was expecting this update for next week! Your confidence in the process is also great. I would have done a dry test before attempting to rebuild the transmission and transfer cases, but you did the opposite and with better results and less time involved.

Everything looks like they belong in there.

Thanks a lot!

One thing I forgot to mention is I did have to beat the firewall sides in a bit on both sides. The passenger side was basically clear of anything on the inside, so I was able to beat it in a lot. The driver side has the throttle pedal assembly right there though, so I couldnt beat it in as much.

today I was able to add a transfer case mount bracket onto the trans crossmember, as well as run the fuel lines. Tomorrow I should probably get some yard work done though, so not sure if I will get any Patrol work done....hooray for responsibility!

well after I finished some yard work, I got a bit of work done on the patrol. I made the throttle bracket, as well as ran the main power wire. I think since the engine is in, I will start on all the electrical items and get it cranked up!

Look like a tight squeeze with the steering column for the exhaust on the driver's side.

I ordered a set of block hugger manifolds, we shall see how they fit. I think they will be ok though.

last night I was able to finish what I believe to be all the wiring for the rear of the vehicle. taillights, rear interior light, fuel pump, electric speedometer. installed, loomed, and held in place. I also made and installed the hard section of clutch line and bled the clutch. it works great!

i got the exhaust manifolds in! They fit pretty well, but I did have to trim the side of the engine mount on the passenger side a bit. I will probably pull that manifold back off and trim it down some to give me even more clearance. Unfortunately some of the spark plug connectors are a tight fit, so I will order some new plug wires with 90 degree ends on them and that should fix it right up. But at least I can start on my exhaust routing now.

Once again, you move fast with your work. Congratulations. :clap: :clap: :clap:

We knew that the fit was going to be tight, and it seems that you have the minor issues sorted out. I will consider modifying the foot well on the passenger side, and install a removable access panel to help you with the spark plug on that area.
