customer project: 85 3.4l 5vz-fe swap

[ORS]

as the prevelence of older toyotas with swapped 3.4l v-6's increases, we decided to post a step by step build on one we are doing here in the shop. we have done many variations of these swaps in the past. our present patient is an 85 runner with a live axle, and a 22r engine and drivetrain. we found with these swaps each model and year of truck has its very own uniqueness to it. questions are welcome and we look forward to making this journey with you.

any pics of the jewel?

[quote=Four Runner;961810]Sweet, and oh yeah...



LMAO!! Sounds like a presidential/political quote!! Hmmm, something on your mind right now besides the project/work??

QUOTE]

i tried to sneak that in but your sharp eyes found me out. yes, we are planning to run in the 2008 presidential race. there are injustices done to the off road community everywhere and we want change now. as a reputable fab shop that has a past working for for factory Toyota, we feel we are more than qualified to run as representatives of our community.
not really, but we will be running a 2000 taco auto with twin 85 t-cases adapted to it... thanks for all your interest

Pics?

[Broken wrench]

this is exactly what I want to do with my runner, pics please plenty of pics!!

[ORS]

The moment has arrived: picture time! It excites us that many of you are so interested in this project.

What axles, tires, trans are you gonna be running?

[ORS]

and here are some more of the first step of our build:

[ORS]

We are going to be keeping the stock axles. As of right now we are staying with some 35x12.5 r 15 BFG A/T's. The transmission will be a 2000 Taco auto, with twin t-cases from an 85 adapted to it.

[Broken wrench]

what is the deal with the other front end, was the old one bent?

a quick question about 3.4 swaps.I have an 88 3.0 auto runner,can I swap a 3.4 in and use my auto tranny or is the bolt pattern different?

[thefatkid]

Broken, I'm in the process of doing the 3.4l to the 340h. I have not driven it yet(or started it) but I'm getting close. I've heard of people having issues with shift timing so I'm not a 100% this will work. It does bolt up though. I've tried to rewire the tranny as much as possible, to be correct for the 98 year. I hope to be running by the end of the month so I'll post up more then.

ORS is sick. Their 3.4l swap parts make things soo easy. I'll recommend them

Yes, you can use the 88 Auto, BUT... your going to have to use a 3.4l auto tranny ECM. If you run a manual ECM, you'll have mis-fire and timing problems.

If you are doing the 3.0l to the 3.4l, they will bolt up to the stock tranny. Whether it's an auto or a manual, they will bolt up. The only difference is in the ECM. If you don't swap them out for a 3.4l ECM, you will have mis-firing and timing problem's.

I know it sounds easy, but there are a few more thing's that you have to do to do the swap, but the general consenses says that it will bolt up to the stock engine mount's and tranny pattern.

Also, Marlin Crawler make's a whole crap load of bell housing's... i am sure they have something along the line's of that swap

Sweet...

Anychane you can host the photos elswhere with the img links, so they are fullsize in the thread and I can see more than 1 at a time?

[ORS]

Yeah, check out pirate forum, it has all the pics on it.

They only make 1 bellhousing, RZ series motor to R series tranny.

We just finished mounting the battery tray on the front clip over the weekend. After that we sprayed the whole thing down with some bed liner for durrbility and longetivity... not to mention it gives the engine bay a clean look as well. Stay tuned: more coming soon!

[ORS]

We have more updates on the 4Runner! Over the past weekend we stripped the firewall bare of its bedliner paint job, and any one that has done the same knows, it was a job and a half. with that done we placed our new F-clip on and re-spot welded it using the same welds for cleanliness. After that we re lined it. Now the only hurdle between the crossover stearing is to apply seam sealant to the seam and to spray it with bedliner.

[ArkieTaco]

I wish I had the time and money for this. I love it.

[ORS]

It is time for another update on our 3.4 swap into the 1985 4Runner! Since you have last heard we have finished painting, sealing and routing/attaching the wiring to and through the clip. we are really happy with how the project is coming along, although being shorthanded and busy these past few weeks and not being able to dedicate more time to it. Here are more pictures for you all, hope you enjoy them!

[exacto]

if you were to use photo bucket instead of ttora's picture upload, then the pictures will be bigger and you dont have to click, but thats only a benefit for us, the readers...

[ORS]

After finishing the front clip it was on to Marlin Crawler's crossover steering kit our customer wanted to convert to. This would have been much harder than it was if the engine had already had been in, so we did it before we are putting the engine in. We first cut off his old power steering box mount, then ground and buffed it down. First we had to remove the old steering system. With that removed, we preloaded the bearings then bolted up the Marlin knuckles (which were not only prettier, but twice as thick too). Then we installed and adjusted the tie rod, followed by the draglink. After that we welded on the stout frame plates and bolt holes so it could accept an ifs steering box. After everything was checked the box was removed and everything was painted black to match the rest of the engine bay. The list of prep work before the engine gets dropped in is getting smaller and smaller. Till next time, let these pics hold you all over.

[ORS]

Sorry for the long wait between updates. Our supliers were back-ordered on some parts that were vital to progress on this project. We have just got the dual t-cases assembled and mounted to the A340 auto transmission. We used a Marlin R-10 transmission adapter which allows us to clock both cases 10 degrees for some additional front output and drive shaft ground clearance. This will all be mounted with a R-10 x-member from Front Range.

We fully rebuilt, cleaned, and resealed both transfer cases. Here is what you are looking at:
-A340 (01 Tacoma)
-Marlin trans adapter with R10 (rotated 10 degrees) option
-gear driven reduction box w/ 2.28 gears and Marlin 23 spline inputs shaft
-MC07 standard rotation adapter
-gear driven transfer case w/ Marlin 23 spline input and 2.28 gears

There are lower gearing options but we think this will work very well behind the auto and an engine w/ power.

[ATLRoach]

What are you guys using for engine mounts?

[ORS]

We will be using our performance 3.4L engine mounts and fabricated frame mounting brackets. Stay tuned, more pictures and text coming very soon!!!

[wslytoy]

YAY...... photobucket haha!

I love yalls buildups, very extensive and informative. Do a 2.7 swap and post plenty of pics .

[Hayes]

wish I had those funds...boo for brokeness!

[ORS]

The engine is mounted in the engine bay! Since our customer was wanting both a dual case setup and an engine conversion into an older truck at the same time we had to mock up brackets with the engine and transmission in as they will sit (and yes, bolted together). We set him up with some of our ultra stout performance motor mounts as well. With the mounts we made some custom frame tabs to ensure the best fit possible. This was not a simple or easy process. Careful measuring and examining went into checking many clearances: Exhaust to firewall; trasmission tunnel to transmission and bellhousing; fan to radiator; oil pan to steering, axle, and suspension, not to mention getting the engine straight after appeasing all of the previous gods. After tacking the tabs we unbolted and removed the engine and transmission. The motor mounts' frame tabs were then gussetted and the welds were finished. After that came a thorough frame cleaning and painting, including the motor mount tabs (read more on the transmission/t-case/crossmember install coming soon). We also heat shielded the E-brake and speedometer cables where they run close to the exhaust (the old 4 cyl bodies were the worst), thus protecting them against melting/ becoming brittle.

Now here is the most important part: pictures!









coming out

going back in



done!

[Broken wrench]

now make me a set of those motor mounts so I can start my project!

[obex26]

And what is a ballpark figure of what YOU guys charge to do this. In same truck and configuration as you are currently doing?
