Builds Cruisermatt's FJ62 Build-up (2 Viewers)

[cruisermatt]

Now that we are on the topic, here's some NV4500 tech.

There are three versions of this transmission you need to know about:

1. 92-95 Chevy
2. 96-up Chevy
3. 96-up Dodge

#1 will be referred to "Early Chevy" and #2 will be referred to as "Late Chevy" for clarity.

Early Chevy has a 6:34:1 first gear. It has exactly the same input shaft and front bearing retainer dimensions as an SM465, the one people have bolting up to Toyota F-Series motors for decades. The only difference between the front face on an Early NV and an SM465 is the bolt pattern on the main case. If they were the same I would be able to just use a 3-speed bellhousing and this would be easy. Not the case unfortunately. Two options that I can think of to use an Early Chevy NV:

1. Drill the transmission case for the SM465 pattern (This has been done before, however it was in a SM465-NV4500 swap where they used a Chevy bellhousing. When you drill the case there isn't enough room to bolt bolts from the outside, so you would bolt the bellhousing to the transmission then the bellhousing to the engine. This won't work with the F-Series bellhousing as the bellhousing has to go on before the flywheel)

2. Make a plate to bolt a Chevy bellhousing to the 3FE. The only problems I see with this plan are that then the input shaft would be too short by the length of the adapter plate. And I would like to keep all Toyota clutch components besides the clutch disc.

I think the answer will be a creative to solution to method #1. I would like to use the Early Chevy for the lower first, although any version will be an improvement over H41/H55f.

The Later Chevy is the same as the Early, except that the bolt pattern in the case is different and it has a 5.61:1 first gear.

The Dodge NV4500 is the same as the Late Chevy except for the I put shaft, which is longer and thinner. This characteristic makes an adapter plate much easier, however I would have to find a new custom pilot bearing/bushing and figure out which clutch disc to use and how much to shim the throw-out bearing retainer, where's with the Chevy dimensions all that information has been know for decades.

Decisions, decisions, decisions.

Here's the bottom line: I'm not afraid to cut, I'm not afraid to weld, I'm not afraid to break out Solidworks, and I'm not afraid to use a milling machine.

When you have the right tools sacrificing benefits for "bolt-on" is kind of lame.

Although in the end, this will be a "bolt-up"

If no one has realized yet, trying to improve to the maximum is a bit of a disorder I have. It won't ever stop

I have two primary motivations for this project: Highway behavior and Off-road ability. This just seems like the best option to nail both.

And I haven't even mentioned the very best part, the ability to bolt this up:

I've ridden in an FJ40 with an NV4500. Fifth gear was never used unless you were going 70+ on the highway. And at that point things were screaming. Granted this was in a 40, but I think the H55F is a much better choice. (I'm partial though).

I definitely admire innovation. I'm just content with Toyota's limit. Low first and OD 5th. Boom. Done.

 

[cruisermatt]

How tired was the motor? Mine runs bad-ass.

Also keep in mind that I have 4.11:1's, and going lower.

 

[klinetime574]

The motor was in pretty good shape. I wanna say it had 4.11 and 33's, but I'm not sure. FJ40's tend to be a little bit of every year lol.

Yeah I think with 4.88 and that huge OD you'll be alright. It's gonna be funny at low speed on the street though... Burnouts and lots of shifting!

 

[cruisermatt]

2nd in an NV4500 is 3.5:1, the same as an H42 first. In fact 2-3-4 are pretty much the same ratios as an H42's 1-2-3-4 so at low speeds it will be quite street-able.

Does that guy want to convert to H55F and sell me his adapter?

I called Advance Adapters and it's been discontinued for almost 10 years!

I bet not. Their 40 is perfectly happy as a running and driving vehicle

Funny story about the miles. When my parents bought it in 1995 from a dealer, it was advertised had having roughly 40,000 (if I remember the story correctly), and the truck had cost $12,000. A few years later, my mom was pulled over while driving by a state trooper, and told her vehicle was being federally investigated for mileage fraud. It turned out the Cruiser had maybe 90,000, and the dealer had to give us $3000 back as my parents had no intention of selling it. So nobody really knows. So right know I'd guess around 250k, it runs great, cool all the time

They pulled your Mom over b/c the vehicle was part of a fraud case? Crazy!

You should look into the Toyo Open Country R/Ts. Better street performance than M/Ts but still more aggressive than A/Ts. Significantly cheaper as well...

Dude if you 3-link the front that would be so sick. I want to do that eventually so that 35s will look normal. Im guessing frenched chevy springs in the rear?

 

[PabloCruise]

I want it in chrome, although that might not be cheap.... Looks like an aftermarket future. But my real main priority is getting rid of all the oil leaks and getting the brakes a little tighter. Plans are a rebuilt 3FE, highly possible H42 swap. When I get around to it, a T100 Brake MC to go with the current TLC calipers, and I want to eliminate those backing plates.

Just finding your thread, and enjoying it! What size m/c did your 62 come with?

I use a brass drift, on the nuts

Uhh...

I decided to do the whole thing in white. Anyone think it's a bad idea?

Wow, it is starting to get real!
Looks like you have a great space to work in.
I like a lighter color on an engine rebuild. When the machine shop messed up my 2F oil squirter, I was wishing my engine was something other than black. I think my next rebuild I will go with battleship gray - easy to spot oil leaks.

All the posts you're quoting are years old, lol. It's funny to see the plans I made and kept and didn't keep.

It would be a great spot to work in if there wasn't always non-running sports cars in the way.

I ended up doing the whole motor in black - pics are farther back around December 2014. Believe me - you know it's leaking when there's a nice puddle under the motor. That's why I'm doing oil pan and side cover tomorrow morning.

I don't even remember what stock or the T100 I replaced it with are, 7/8" and 1-1/16" I THINK?

 

[PabloCruise]

I look at all this and try not to think about the day when I tear it out for a diesel swap...

Just send it my way when you do, I will stuff it in mah Ion Pig!

 

[PabloCruise]

And to continue my habit of painting stuff under my van random colors I did up the inspection cover in fire engine red.

I put the tire back under the car, where it will reside for a few months...

I am confused, is it a van, or a car, or a Cruiser?!?
