Thanks Mike, your kind words are very much appreciated.

Sure, I'd love to hear their thoughts. Especially because the same seller is about to put another 1st Gen on BAT soon.

 

My 4Runner has a different headliner fabric in the cabin. But the hard top has the same type, it looks like the PO covered it with grey vinyl.

 

I'm sure that's true, just another sloppy attempt at restoration. I'll be taking it to the upholstery shop when I have some time. For now the roll bar is holding it up .

 

The brakes in this truck were horrible, despite the seller stating that "the brakes are great". So I bought some Wagner ThermoQuiet pads and installed them. The seller apparently did not believe in lubricating brake hardware. The pins and pads were completely dry and rusty. With most of my tools packed up for the move, I did the best I could to remove the rust and apply some lube to the pads and the pins. The caliper dust seal looked very suspect, so I'll probably replace them down the line, after the move.

Pins and pads, with no lube:





Caliper dust boots look a little sad:

Wow, the way that truck was presented on BAT I sure wouldn’t have anticipated the problems you’ve discovered so far! Like how you’re chipping away at everything…no stone unturned. Great work!

 

Wow this is a great thread and very timely! I am putting my motor back together and am about to spray my engine bay with some paint. I will follow and keep tabs on this one for sure!

 

Thanks for the link to this post Leon, very informative and your attention to detail is wonderful.

I really like that you are trying to replace with factory original when possible and to that end i must Google this "Amayma" you speak of. It appears to be a place where elderly Toyota Gnomes recreate parts out of fairly dust that few will ever need but many cannot find. Thanks for the part numbers and pictures as well. I am frightened that the cost of these parts is similar to fairly dust but such is the price of doing things right.

Not much going on, we're moving to Portland so everything is buttoned up until the move is done. I do have about $800 of stuff coming to me from Amayama, so that's exciting.

I made contact with the previous owner of this truck (not the flipper I bought it from). A really nice gentleman, loved his truck, and really took care of it. Too bad the flipper got his hands on it in between.

 

Hi Leon, I checked the Amayama site for a dome lamp assembly and found them. Question is it looks like you have options ordering from Japan and the UAE. Question is, are they all the same units with no differences just being stored at different locations? Cost and shipping to the US seems much cheaper if you order the part from the UAE instead of Japan. Does it make a difference in the part depending on where you order the part from.

Thanks Mike

 

Hi Mike,

Yup, there often is a significant price difference between UAE and Japan. It'll be the same stuff, just a matter of what's cheaper for part and shipping costs. I find it more economical to order many things at a time (to amortize the shipping costs), and it usually ends up being Japan.

 

Thanks Leon for the information.

 

On Amayama an original alternator is about $850 plus another $50 for shipping.....geez I think I will get it rebuilt locally makes a lot of money sense.
Probably gonna be that way with most parts that I need, if I can get it rebuilt locally may have to go that way. Thinking about the Carb on my 22R.

 

Yes, you'll find that Amayama is very non-competitive for items that are fairly common replacement parts (alternators, starters, etc). Those are best purchased at US dealers. I bought a remanufactured Denso starter for about $200 from Boch Toyota.

 

I received the new front calipers from Rockauto. Then I started thinking, is now a good time to bite the bullet and upgrade to larger calipers/rotors, and brake booster/1" master cylinder from a 2nd Gen V6? From what I read, those who've done it report a very significant improvement in performance.

I did something similar in my 3rd Gen (the Tundra Brake Upgrade), and am pretty happy with the results - if nothing else, my rotors have not warped ever since then.

But I'm wondering if this would be a bad move for the 1st Gen, which I am meticulously trying to restore - would 2nd Gen parts be considered a big turnoff for folks? Thoughts?

 

I don’t think so. It’s a safety improvement and invisible to the untrained eye. I have a whole v6 brake kit waiting for me to find time for the project. Maybe now that truck #2 is on the road truck and summer’s over #1 can get some attention. I bought the cross drilled vented rotors(powerstop i think)from Rock Auto for a bit of a restomod look.

 

Makes sense, thank you. So what items would I need for the complete upgrade - rotors, calipers/pads, booster, master cylinder? All from a V6 2nd Gen?

ETA: the more I read, the more alternatives I see - S12W vs S13W (does the latter require grinding to fit the wheels?), T100 wheel cylinders, etc... Any guidance would be greatly appreciated.

 

All the parts i bought are from a v6 second gen. I may have to trim the backing plates to fit the larger calipers(i think i read that somewhere). I did not buy a booster but i bought a master with 1” bore. I assume the booster i have will work. I don’t know about wheel cylinders.

 

I think there are a few ways you can go about doing the V6 upgrade from my research. If you haven’t run across this thread here on YotaTech it’s a good read on the upgrade, with part numbers included…

I can’t speak from personal experience regarding the performance as I haven’t installed mine, but here are the parts I picked up from Toyota:

47730-35090-84 RH reman s13wb caliper
47730-35090-84 LH reman s13wb caliper
43512-35200 rotors
47201-60551 brake master cylinder for ‘95-‘97 FJ80 Land Cruiser
47550-60120 rear cylinders for ‘81-‘96 Land Cruiser or ‘93-‘98 T100

I picked up a V6 brake booster from a ‘94 4Runner from a friend. Toyota discontinued the brake master cylinder that fits that booster. Advics/Aisin BMT-051 is what some have gone with due to the connector plug being on the cap of the cylinder. The Advics/Aisin version of the Land Cruiser master cylinder is BMT-046. The Advics/Aisin version of the larger FJ60 rear cylinders is WCT-011.

Another way to round up Toyota part numbers for this upgrade is to grab a VIN from one of the ‘92-‘95 V6 Toyota 4Runner/Pickups off BAT and plug that in to www.toyota-usa.epc-data.com to find the part part numbers.

 

Thank you, this is very helpful! I've read some discussion about S12W vs S13WB, with some warnings that the bigger S13WB may not fit inside the wheel without grinding the caliper, or using spacers. Any definitive info on that? I'd prefer to not have to do that, so maybe the S12W is a better choice?

Also not completely clear on the difference between BMT-046 and BMT-051 - they both seem to have the connector pigtail coming out of the reservoir cap.

I also see some places like LC Engineering sell the entire combo (minus the booster), though it' a little spendy.

I'll keep researching, thanks for the info!

 

I read the warning on LCE about their V6 brake kit possibly not clearing, but I don’t have any first hand experience. When I was searching for the V6 calipers I looked at Marlin Crawler, Yotamasters and Trail-Gear. I reached out to Marlin Crawler last year and they told me their calipers at that time were S12W. Not sure which reman caliper the others sell.

In the thread I linked above using the S13WB calipers it looks like there’s some trimming of the dust shield involved. Not sure if that’s necessary with the S12W.

One difference between the V6 Pickup/4Runner Aisin BMT-051 and the Land Cruiser/LX450 Aisin BMT-046 is where the brake lines connect to the cylinder. The BMT-051 has both connections on the side, while the BMT-046 more closely resembles the current one on your 4Runner with one on top and the other on the side. Less bending of your 35 year old brake lines to connect.
