Damn, did not see myself making a build thread again, but I have started to get excited about the build again after slapping 37s on so why not!

Starting from the beginning. In May of 2014 I acquired a freshly imported 1999 Toyota Hilux Surf, SSRX Sub-Model (Bone Stock). It has the 2.7L 3RZ (yes gas engine). Bought it completely stock with 121,xxx km's. It was originally from Tokyo and I am completely in love. So many cool little JDM aspects to it and it honestly gets all the looks.

The day I brought her home:


4.5 years later, and its been a hell of ride. You would not believe the fun I have had diagnosing every little problem when everything is setup differently than the north american trucks. Literally every wiring harness, every bolt location, everything has been different. I probably would have been better off learning Japanese to be honest, but I wouldn't have it any other way. Its always a pretty serious feeling of accomplishment tackling issues that no one else has documented on before.

How she currently sits (trail shots of 37s coming):

It is hard writing all this now and looking back at everything that has been done to the truck, so I'll give you the short version. Lots of different lift setups, progressively growing in tire size (31, 33, 35....) and lots of really cool trips (I like taking photos too).

Here are the main things (that I think are of actual value) that have been done to the truck:
  • Re-geared to 4.88s
  • Rear axle swap and Toyota E-Locker install
  • MCM Fab Long Travel Kit (Packaged by SRQ!!!) with ADS coil-overs
  • McNeil Fiberglass Fenders
  • Dick Cepek Fun Country's 37/13.5/17
  • Smittybuilt 9500lb Winch
  • Rear drawer system
  • Double din switch panel (Surf's are triple Din)
  • Front tube bumper
  • Non-Center Diff-Lock Transfer Case Swap (there's a long story with this one)
  • Manual Hub Conversion
  • Transmission Cooler, fan, and Gauge
  • Tundra brake upgrade
  • Skids and Sliders

After writing all that, realizing that I've actually done more than I realized to this truck. I will be adding lots of trip and some mod photos to catch up.

Moving forward, I will likely update this build thread with major updates, but I want to focus it more on questions. Please ask about anything I have ever done or why I did things a certain way. Love to lend a helping hand and as I add more updates about past modifications, I hope they can help the community.

What write ups would everyone like. I am going going to do unique ones. Here are some good options I think:
1. Actuator driven transfer case troubleshooting and eventual swap to manual transfer case.
2. Manual hub conversion
3. Long travel with manual hub job
4. Wheel well clearance'ing for 35s/37s

Let me know of any different ones you'd like to read/have, or if you like one of the above!

We've got so many 3rd gen runners all of those would be of great benefit to the forum. Looking forward to seeing them. You've done a lot to that rig.

We do have a tubbed wheel wells thread already.
https://independentoffroading.com/index.php?threads/tubbed-wheel-wells.13/

And the what size tire should you really run.

https://independentoffroading.com/index.php?threads/realistically-what-tires-should-you-run.111/

I’d definitely post up the tire size fitment up in those as well to give people ideas of what goes into fitment.


The manual t-case and manual hubs are good ones to share as well. Never seen a manual hub LT rig before.

Haha yea because its the only one around. Fairly certain I am the only LT Surf with manual hubs and 37s in the world.

What did you have to trim in the rear for the 37s?

are your 4.88 adequate for them?

When should I come up to BC?
I actually haven't trimmed a thing believer it or not haha. I will probably need to cut a little bit but I'm ok with it for now.

And I'm dead serious. Book it and tell me.

I want my up travel back in the rear. I'm gonna be trimming like crazy soon.
Up travel is highly underrated. I have about 6.5" of up travel at ride height now and it's been fucking awesome to not ever bottom out anymore. I used to have about 5" of up travel, but had 2" taller ride height. Even that 1.5" has helped a bunch. Plus having hydro bumps really makes another huge difference. I can't wait for Ocotillo in a couple weeks to really give it some hell.

You don't have to trim if you just extend your bump stops more ;)
GET OUT OF MY ASS. :flamethrow:

I love my rear bump stops and I don't care who knows it! :banana:

Yeah, its not a triangulated 4 link cut into the cargo area for maximum bumps, but its better than stock/ what my previous setup was. I thoroughly enjoy how my rear rides compared to other similarly set up 3rd gens (Few and far between) I can hit nearly and whoop, divot, ditch on moderate trails at 30-40 mph and my rear soaks it up great. I'm now working on setting the front up to handle it as well as the rear. A shock revalve and air bumps up front is in the very near future.

answer me on 4.88s. I need to know for science!

I will make it up there in 2019 for sure! As long as you make it back down here to the red desert
I will absolutely come down one day for sure. Yes the 4.88s seem to be good for now. Better fuel economy with the 37s than 35s. Remember though its a 3rz. So would be a different power ratio than your truck.
