ROTF lt1fire (Now a L84 Gen V 10 Speed Swap)

[lt1fire]

Reason I don't care about the motor in there is I found a rebuilt 3fe about 10 miles from my house. So I picked it up and i'm slowly cleaning and putting on all my spare parts to it.


After the install and break in period i'll put the turbo on . If I don't like it for some reason there is always my 4bt I could put in or an LS swap

 

[lt1fire]

So for now the plans are.

Get the title and have it shipped.
Install new motor and break it in.
Install turbo kit.
Do rear bumper.
Can't seem to find my skid plate so buy a new skid plate, most likely iron pig again unless there is something cheaper and as good around these days.
Refurb' my toyota OEM winch and install in place of the smittybuilt one I currently have on there.
Install the OEM toyota sleeping platform I picked up from @torfab a few months back.

Drive and enjoy. Will be my DD as I work from home now and i've I have to travel far for work they rent me a car anyway.


Longer run.
Decide if I want to stay yota gas inline six. If I do build up a 2f to install. If not figure out if I want to do the 4bt swap or get a OM606 or LS, etc....
Figure out better CR
Always wanted to do volvo portals at some point but they are hard to find now and if I go diesel then i'm not really going to want 5.99 gears.
That last one may just be a fantasy though lol.
Although if I do need more beef axles I do have a super duty one ton set with 3.73 gears HP D60 front and the rear 10.5 Sterling is locked.

They were for our 68 bronco that was going to be a crawler and then wifey wanted to restore it instead.

 

[lt1fire]

Ohhh completely forgot about this thread for a while.

I ended up selling the rebuilt 3fe to a local because my buddy @mtweller sold me his awesome 2FE out of his 40 since he was doing a 6.0 swap

However plans changed on that also when we pulled the old 3FE out to do the install I decided to switch gears and go with a V8 swap.

 

[lt1fire]

After listening to Tor from Torfab talk about the Gen V swaps everytime we got together I finally decided to go with that. I now have the cruiser back from NC to where I now live in WA. Thanks to @GarnerFJ40 and @SFROMAN for towing it out to King of the Hammers last year and I towed it back up here.
I also have the L84 5.3 V8 and 10 speed (10l90E) trans in the garage. I have the @torfab adapter kit so its pretty much a bolt in affair (except its built for 1fZ frame mounts and this has 3FE ones so i'll need to weld in some 1FZ ones). I have quite a few other parts for the swap ready to go and will be sending my harness and ecu tcu off to swaptime to get that done next week. Then its off to the races, as my work schedule allows for time. Few pics of all that

I'll be keeping track of parts and costs of this with sections for things that are needed and just extra things I did that aren't needed.

I'll be following threads such as for guidance as these gents have set a great example of what to do

Accessory drive:

Let it be no secret, I set out on this project closely following Matt’s project Sparkles Build and the Project Wintergreen build threads. These two trucks and installed methods are pretty much directly copied here. One area where both builds have commented needing improvement is the L86 power steering solution. I too ordered the Tejas Steelworks kit, pump, and pulley. And I was pretty much resigned to the reality of a tight fit to the steering gear box and pump/frame.

Then I learned that Mitch at Swaptime Offers a “swaptime drive kit” for the...

Worked through re-bleeding brakes, adjusting power steering pully alignment, filling transmission @ temp, etc. and the 80 swap went for its first lap around the block . Plenty more to work on, but it has left it's semi-permanent spot on that concrete pad to the left for the first time in ages.

Things 100% needed for swap, somethings for others would be combined as most used engines come with coils, wires, TB and MAF mine didn't and the low price kind of reflects that so they are included in my list. Also there are alternatives to things such as the PS things from other companies may be cheaper or more expensive.

This is what i've got and spent so far I'll add to it when I order some more parts next week and get a grand total with parts bought and parts sold. At the end.
For now it waits and stares at me whenever I open the garage door.

 

[lt1fire]

Been slowly adding to my parts pile over the last month or so. Some things are 100% completely not needed to do this swap and were my own personal preference to build the L84 a bit. Some I needed but others wouldn't as they are normally included in the initial used engine purchase. (mine didn't have coils, plug wires or a throttle body/MAF on it when I got it) But I got a great price on the initial buy.
But in the picture I have (and i'll add these to the list above with prices and places to buy i'll have two lists, things I need and things I didn't)

L86 intake (not needed but it is a great upgrade for the l83/l84 5.3 engines. This with the matched TB has shown around 15HP to the wheels on most documented installs)

L86 Throttle Body (see above, I needed a TB so it made sense to buy the larger L86 one which is the same price as the stock l84 one and then a tad more on the L86 intake. L84 is 80mm l86 is 87mm)

ICT Billet PS adapter with saginaw pump, new pulley, new belt tensioner. (I still have the Tejas one but this puts the PS pump uphigh on the DS of the engine. Easier for installation and you can use this on the L87/L84 due to the different WP design from the L83 and L86)

Full DOD delete kit with upgraded L86 profile cam (this is actually not needed as you can just program out the DOD system and plug the solenoid holes, there are still rare instances of the DOD lifters failing even after this is done and the newer Gen V motors L84 and L87 have all cylinders on the DOD lifters instead of four in the earlier GenV or older GenIV LS ones. This also gives me more power from a better camshaft aswell. I may not have done this to save money but I had the full kit lying around from an earlier L83 motor that i'm at one point going to build for a ton of power and would need bigger cam anyway so i'm using it on this L84. All I had to do was get different solenoid plugs for the newer motor.)

TorFab Adapter Kit (Great kit completely bolt in for a 93-97 as mine is a 92 I actually have to weld in some junkyard frame mounts from a 95 first no biggie)

Torfab Airbox - technically not needed but much better than an open to the air filter or the stock one

Brand new OEM spark plugs and coils with upgraded 10mm plug wires (needed the coils and wires and the plugs were cheap and good insurance)

L84 Oil Pump (basically replacing all critical and hard to get to parts that i'll have to take off during the cam upgrade not needed just for my own preference)

A343 to cruiesr t-casae adapter (needed for torfab kit, if you have a 95-97 cruiser you will already have this piece)

New Fuel pump DeatschWerks DW200

105 steering box upgrade (not needed at all but my box has slightly twisted splines so as good enough time to upgrade as any)

HP tuners module (not in picture as it's with Mitch at swaptime but needed for swap and tuning)

Various gaskets and seals for tearing down the motor and putting back together for cam swap

Mass airflow sensor (OEM L84)

I'm most likely forgetting things on that shelf as its been a perpetual christmas for the cruiser event over the last month, will upgrade when I remember

Still waiting on:
DBW gas pedal
Swaptime harness (Mitch has it and is currently working on it)
Muscle car module from swaptime
New cam phaser bolt
Walnut media, blaster, and cylinder head adapter to clean out the carbon on the intake side of the head. Motor only has 25k ish on it but theses DI motors build up pretty fast, really only down side to it
Fuel lines and two in one FPR and filter from evil energy (recommended by torfab)

Still left to order
DBW pedal bracket from Torfab
Spal fans and shroud from Torfab
Speed Engineering headers they are currenlty out of stock and you can't order till they resupply.
I'm sure various other things i'm forgetting currently

One thing I need to figure out is the oil pressure sensor. The L84 needs the stock one for the ecu to run the motor correctly, this is not so on the earlier Gen V like the l83 and l84. So i need to find a dual outlet block of port for where the oil cooler is to run a stock one and a toyota one for the gauge pod

 

[lt1fire]

Started breaking down the L84 to do the DOD delete

 

[lt1fire]

Tad bit more work today ony lunch break.
Removed the DOD wiring harness and solenoids. Different from the GenIV and early Gen V DOD set up.

 

[lt1fire]

Then plugged them back up with the Brian Tooley Racing solenoid plugs then clamp them down with a washer and the original solenoid bolt.

Now i'm just waiting on my new weighted crank bolt socket to arrive. Can't seem to find where I put mine for a ls/lt engine. Then the teardown continues.

 

[lt1fire]

Not much work done. Work got busy, had to have my niece and nephews for a week and went to KOH.

But the swaptime harness, my HP Tuners module and my tunes and unlocked ecu and tcu arrived. Mitch forgot the muscle car module to add tap to shift so that is on the way.
No work this weekend so hopefully get more work done on motor build.

 

[TXIN]

Cool build,

What year is that 10l90 from? Looks like you're running the E90 ECM?

I'm doing a similar swap with a '25 L8T and an '18 10l80 but I'm going to run an E92. Definitely need to get an MPVI4 as well, it's apparent I'm going to have a tuning challenge on my hands. Despite having done tons of research, I somehow missed that 22+ engines run 6mm injectors VS the older 7.5mm so I'll likely need a full custom tune.

I'll be very interested to see what you do for a shifter. I really want to do a cable shifter to avoid cutting a hole in my floorboard...

Its a 2021 both engine and trans although from different vehicles. Isn't a 25 L8T using the global B stuff. I was told to stay far away from those but i'd say give Mitch a call he straightened me out pretty fast on what I needed. My engine was originally paired with a 8L so we had to change a few things around.

 

[TXIN]

Yeah, it is global B but as it turns out, the sensors are all the same as global A L84/L87, etc.

I Spoke with Mitch the other day about it and basically came to the conclusion that it's all in injector tuning. I could always swap the heads for the older style but I really don't want to open up an engine with only 2 miles on it so I'm going to give it a shot via HPTuners first.

Did you have any issues getting ahold of Mitch initially? I've been trying to get in touch to confirm a few things before I pull the trigger on a motor/trans and haven't heard anything.

I did, however once you get ahold of him he will almost always pick up the phone afterwards. It may be that lots of people call to pick his brain without the intention of actually buying anything within the next year.

I have wondered why the change to the smaller injector size but couldn't get an answer. I think its actually the global B transmissions that are virtually impossible to use in a swap.

 

[lt1fire]

I need to update this thread a bit better later, lots more bought and acquired. Head intake ports have all been walnut blasted (that was actually quite fun and gave me reason to buy a few more toys) its amazing the build up on DI engines with just 25k on the motor.

 

[TXIN]

I have wondered why the change to the smaller injector size but couldn't get an answer. I think its actually the global B transmissions that are virtually impossible to use in a swap.

Yeah, the later transmissions don't even have a mechanical PRNDL shaft. It's all electronic like an 8HP or similar. No one seems to support that configuration for swaps yet...

Part of me actually wanted to try my engine with an 8HP and standalone controller with the DomiWorks 8HP to HF2AV adapter but Tor's kit is too bolt on friendly to pass up, IMO.

I haven't jumped on the 8hp train yet. Ive driven a few performance cars with them and driven a performance car with the 10l80E both good IMHO
