1993 HDJ80 - 5 Speed / 1HDT / LOCKED / LHD - slow build

EGT and BOOST gauges hooked up, I think they are calibrated well. I’d love to hear numbers on the 1hdt and what I should be looking out for! Everything on mine is OEM For the most part.

EGT probe is pre turbo. Boost vacuum hose was tied into the hose coming out of the ‘turbo’ crossover manifold.

Initial tests show:
Idle after warmed - EGT ~360F / BOOST ~4.6 PSI
110kph @ ~2500RPM - EGT ~600-800F / BOOST ~10 PSI
During acceleration onto highway - EGT ~1000 - 1200F / BOOST ~12PSI
Short burst of full acceleration - EGT ~1100 - 1400F

id love to hear any thought on these numbers and any recommended adjustments.

Awesome rig! My FJ80 has cracked fender flare seals as well. What brand/product did you use to replace those? I am looking to redo all my seals soon. How do you like them?
Thanks!

Thanks! I sources mine from Delta Vehicle Designs. They are OEM Toyota seals. They fit and work great so far!

Took 20 minutes today to adjust the injector pumps timing on the 1hdt. 1mm was recommended and it seemed to work a treat. EGTs are down and low rev power is up. No more / less smoke than before. Yellow is the old mark. Blue is new.

I finally took on the Big End Bearings (con rod bearings) this week!

Overall, it was a pretty simple job. The most annoying part was getting the oil pan off and cutting the FIPG. One I was in the motor, i just took my time and did everything by the books. I replaced them with ACL tri-metal bearings.

I followed some instruction I found on here from @bonznfc and followed some other tips and tricks i found in my research Along the way.

The old bearings were COMPLETELY SHOT! I cannot believe how bad of shape cylinder 1 and 6 were in (I just clocked over 290k km). Doesn’t look like these were ever swapped out. Overall, its great to knock this off of the list. Ill run this oil and zinc additive for 500 miles and do another oil / filter change when everything is broken in.

since I have no plans to upgrade the bumpers, I beefed up the front and rear recovery points with IronMan points. I painted them black....

First of a few posts reguarding the new rear tire swingout.
I went with an old Summit Cruisers Kit because I LOVE the OEM look. Plus it’s a million times stronger and more capable than a JDM swingout... PLUS it’s on the drivers side, which is correct to me.

This was my first time ever doing any kind if welding or metalwork. My buddy showed me the ropes and insisted we did stick welding in order to learn the craft. SO FUN! We did it all in his backyard and the local Home Depot parking lot.

thought it would be kick ass to add out own touch... a 2in hitch receiver to hold a cooler or bike rack... NO TOWING!

Pt 2 of the tire swingout... still fabbing and tweaking our own little touches...

for the hitch so it is centered on the car:

Part 03 of the tire swingout:

now just waiting for Steel It to paint it!

 

[BryceDP]

Finished the swingout. A little bondo and steel it: amazing kit @summit CRUISERS Jr

Also fitted a front runner awning!

Really impressive work. Am I reading right that you see 4.6psi of boost at idle? Also, I'm always a little suspect of in-motor bearing replacements. It looks like your bearings were pretty rough, you said #1 was really bad specifically. How did the journals look on the crank?

the crank looks good and healthy. These bearings are known to fail and corrode like this on the 1hdt

retrofitted some One Stone Armrests... love the OEM look and quality.

all that was needed was to reposition the Windsor run lip with some new holes... I took it a step further and bolted it to the door. No rattles or squeaks over here!

i had some spare Trek Pak laying around and decided to get things organized.

Very cool I like that. How do they connect together after you cut it to size?
