Driving back home to PNW from NorCal where she’s been resting @ mum’s the past año.

Temp pass seat delete for first born’s comfort.

269.xxx on clock; avging ~25mpg @ 65mph— not too shabby for original 22re on 33x9.5s!

Found a welder en route to fab up new exhaust due to rot and preserve what’s left of my eardrums.

Thanks for the past 15 years, here’s to 15 more?

Cheers mates

Hey yall, just getting back from a trip sorry to those I have not replied to. Here is the Lid Im getting rid of its in pretty poor condition but with the scarcity of parts out there I figured id give it a shot before chopping the remaining windows out and taking it to the dump. It's gotta go. Local pick up only. East SF Bay Area. Come n get it. DM for setting up address and pick up time if interested.

LIDAR scan

The laser is tied up for a few days so I did a Low Res LIDAR scan of the OM617 Valve Cover.

This model is a bit difficult to work with. Our laser system is designed more for this kind of work and I will be able to fine tune models prior to export into CAD.

Transmission plates

(limited me to one pic) some parts ive developed so far. This began with the transfer case cover which has now turned into a Research and Development of a short throw shifter setup for the split transfer case on the W-56A from the 85 Toyotas, since apparently there is no off the shelf kit for this transmission anymore. Ive made a bunch of stuff like this that has been a life saver. And I wish I had this stuff 10-15 years ago when I built my last diesel Toyota (86 turbo 4wd pickup)

As I build out the models for the 4runner im taking a significant amount of dimensions. Ive noticed that I cannot find a legit dimensional drawing anywhere for example the solid front toyota axle. I.e. dimensional positions of shock mounts, tube diameters etc. Being that im building these models in solidworks it is possible that I could in theory produce engineering drawings (to a degree) for this stuff. It would me nice to know for example the angular position of the leaf spring mounts against the yoke flange of the differential.

The only problem is that, as most good engineers will tell you..Building out dimensional engineering drawings that are actually useful to the people that will need them take a significant amount of effort and time.

Im also considering videoing my shenanigans with the 4runner as I go through this mess.

Side tangent-

My background is machining, prior to engineering and when I reverse engineer something at work I approach laying out every part from the position of a machinist (22 yr old engineers with 6 months of experience either love or hate working with me).

((The forerunner picture))

I got offered 3,000$ bucks for a 1989-1988 Toyota 1st gen forerunner. And it would be my first car. With only around 120K miles on it. I don’t know much other than that and I should hopefully be able to see it soon either this week or today. But my father keeps giving me crap for it.

Should probably add that it is the old V6. And it is a 5 speed manual as well. Which is a bonus due to it being a V6 and getting more horsepower and also it being a manual which is more fun at least in my opinion.

I’ve worked on motorcycles before and I know old 1990’s motorcycles compared to a 4 runner are completely different. But I always have a lotta tools so it would make it easier. I just want someone’s opinion other than my father’s and my buddies.

Need Advice Going to need new rear leaf springs, what is stock ride height?

31x10.5 r15 tires and complete unloaded and leaf springs are flat btw

1986 with the original suspension that I don’t think has ever been touched except shocks and alignments.

I need advice on suspension, I’ve been waiting to take it out on someone mild trails for off grid camping and exploring BLM land but desperately need better suspension, should I go with new stock ride hight or a +2 I just don’t want to crank the torsion bars so much I don’t have any downward travel if I get a +2 leaf springs.

What does everyone have that has more suspension travel and a softer ride off road?

Wiring harness to fuse box

87 4runner

Anyone tell me what these wires go to?

Wiring harness towards the fuse box driver side, they appear to go under the seat

There were two sets and they were taped together with electrical tape. I assume the previous owner did it, but who can say for sure.
TIA

Here is where I am as of today. This is the exact suspension fitment my 85 is running with 35x12.50x15s.

Ill begin modelling the axles and suspension very soon, then for the engine.

4runner CAD

In short, I am engineer. im looking for cad files for the 1st gen 4runner. In the process of restoring my 1985 SR5, and building it up with a turbo diesel and fabricating many parts from scratch. I am slowly collecting all of the CAD files that I can for this chassis and body.

I have access to a $100k+ laser scanner at work, and the operator is training me to use it so that i can tinker when they are off to not interfere with their schedule. Its a two fold benefit because the more I understand about it, the more i can help them. I plan to use this on weekends to take a full 3d scan of the body etc to use as I design parts.

My goal as I collect all this is to essentially create a repository somewhere essentially public to give back to the 1st gen community because this stuff is either non existent or people just do not share. Which is unfortunate.

Part of this is a project so I can grow and learn new things as an engineer, but also to improve the prototype and design process for stuff for my own truck.

Im designing a new short throw shifter for my w56-a for the transfer case, and plan to take REALLY good scans of my transmission for this job. I have a machine shop in my garage at home and build everything myself. The engine is an OM617 and will have very detailed scans as well. The intent is to be able to build extremely accurate models for ideas I have.

If there is interest ill make posts as I progress through this.

Thanks

Lower Power- Stumped

Post image

88 22re

A few weeks ago, my alternator died on my way home. Pushed through a misfire for about 2 mins for a safe place to pull over.

Replaced the alternator, but the truck has been noticeably down on power since. Acceleration and top speed are noticeably slower than it was before. The exhaust also got significantly louder, I don't know if or how these are related, but it's worth mentioning.

Found badly leaking injectors, again not sure how that's related but anyways I sealed those up and the truck is stil| down on power. Fuel filter is new and pump seems healthy. ran some fuel/oil additives and cleaners through following the directions on the bottles.

I've spent the last week making sure the exhaust is sealed, 02 is sealed, there is no catalytic converter, I've disconnected the battery to reset the ECU multiple times. The truck is still down on power and has no codes.

I'm waiting on a timing light to check that, but I really have no idea why the alternator has caused such a cascade of issues.

Any ideas?

Need Advice Front end lift on an IFS

2 Upvotes

Hi there everyone. I know this has been asked probably a million times over the years, but I can’t seem to find a concrete answer to this.

I’m wondering what is the point for upgraded torsion bars. Is it only worth it if you have a heavy winch etc? My truck came with cranked torsion bars on 33s. Terrible ride, poor off road capability. I’m considering doing a body lift because I don’t really want any excess wear on front end stuff.

However, I would prefer to leave it and do upgraded torsion bars and shocks if that would actually fix my problem, being the poor ride. The truck mainly just sees the road and some occasional bumpy stuff.

Thanks.

small thing but i really like when mats cover this much

Do you guys actually notice the extra coverage on truck floor mats, or only care once the carpet needs cleaning? I feel like the edges and area around the pedals get dirty first. Curious what you guys think. Is more coverage actually worth it, or is it not a big deal?

Rear shock mounting

I have a first gen 4runner with a body swap, so I know that things are going to look a little unusual. I'm having a hard time getting Bilstein 4600s installed in the back cause I can't seem to get the bushings compressed far enough to slip the cotter pin in. Does this look like the original mounting locations, or some weird junk done by the previous owner who did the body swap? It didn't have shocks when I got it so I don't have anything to compare it to. I don't have a stock 4runner for comparison so I'm just guessing at this point. I think it's an '85 or so.

85 4runner. Was an automatic but swapped it to a w56 manual. Bought it in AZ then moved back home to Maui. Still have to wire up the reverse lights and do an sr5 cluster swap but it gets me up and down the mauna just fine.

Tow hitch options?

I’m looking to put a 2 in receiver on my 86 for a motorcycle hitch carrier. I currently have the stock bumper but not afraid of changing for an aftermarket on except for the tube frame bumpers, not a big fan of those.

What does everyone else have?

Went limp recently, towed and shop says knock in the engine, who knows what it could be. Perhaps they dig in and it’s nothing or it’s whatever a 22re could cost - maybe 7k?

Any advice from those out there who have had similar experiences with the 22re and what a point to move on, engine swap, estimates, etc. anything will help at this point!

Appreciate the help. Also, no, I’m not mechanically inclined nor do I have the time anyways.

Thanks!!
