What did you do on your 70 series today? (55 Viewers)

Hello there, any one know what is the part number for hood fj73 soft top with windshield rest

I found this part number 53301-60171 but I think its not available any where.



please help me to find it.

thank you so much

Rebuilding the front axle on the 78. Those little axle nut retaining screws on the power locking ring were a bear. Broke almost every T20 bit I had.

And what design engineer decided on hard brake lines going to the calipers, good thing I was already replacing all the soft lines anyways.

What soft lines did you go with?

Toyota.

Toyota.

got a part number? I'd rather have soft lines as well.

My bad, I didn’t replace the hard lines with soft hoses. Just replaced all the old original ones. To get retrofit the stock setup you could make some elbows to go into the calipers and source some longer soft lines. It really is a crappy design with the joint attached to the dust cover.

I'm also thinking of replacing my hard caliper lines with soft braided ones. I guess it's as simple as matching the fittings and giving them an acceptable length. I've been told that soft brake lines can degrade and clog on the interior, so I guess there's a good reason but still.

Nice work!

Yeah these T20 little screws can be a pain. When I did mine, I used a manual impact screwdriver (the kind you whack with a hammer) and it worked like magic with no damage to anything.

The reason this happens is that people torque the bejesus out of them when they install them. IIRC, the FSM specifies a very low torque spec.

Cheers!

Played with a hose. Didn't find where water sometimes leaks in when raining.

Not a single drop of water in footwell. Now we are waiting for the rain...

Let Ian, @SNLC, take it for a drive. Trying to determine if I got a bum turbo or not as I can't get the new turbo to hit the number specified by the manufacture, 18 psi. HIs opinion, I need more fuel, and I don't rev it high enough (I drive like an old man), for the turbo to spool quickly. He was driving it like he stole it and hit 16 psi.

Disconnect and plug the wastegate line and see how much boost you get with the wastegate deactivated. If you get more than 18PSI then it means your wastegate is activating at too low a pressure. If you still can't build boost, you can try to increase fuel while monitoring EGT's to increase boost. Your pipe from your turbo to your intake has a big effect on boost. Does it flow freely? Intercooler yes or no? 4th gear full throttle at about 50mph is where I can get full load and full boost. To see full boost you must have a load on the engine, full throttle and siginficant RPM. BJ73 turbo with TD04-12t waste gate wired shut and as much fuel as I can put to it without causing high idle no intercooler 2.25 exhaust: cruise less than 60mph 8-12PSI, Normal accelleration 15-18PSI, full boost full throttle in 4th gear it builds to 22-24PSI....................Comparing it to some other factory turbo IDI engines that are built to be abused without having to monitor the guages: Factory setup seams laggy but has more punch when it spools up. My setup has good smooth power all around with little lag. I believe If I had a larger turbo it would more mimic factory as in I'd have some lag and low end power may suffer a bit, but increased air and boost might help power and decrease EGT's and heat under high load at highway speed above 60mph............................My engine is fairly healthy with new head and inframe rebuild less than 15K miles so it may withstand more abuse than someone with a more worn 3B.

What turbo are you running again? I’ve said this before but my Holset will hit 18psi on normal driving. I rarely ever rev past 2700-2800 and definitely don’t need that to hit 18. That’s only 1/4 turn on fuel.

Gturbo Green wheel. I think I saw 15.8 on the gage and that was at 3800 rpm, I don't think I've never wrapped it out above 3000.

Wastegate line is completely closed off with a manual boost control valve.

Yeah I’m guessing more fuel would help the spool. I don’t know the size/specs of the gturbo other than it’s a ct26 modded.
My Holset is smaller and just boosts like crazy and I’m basically stock. My boost is very quick and I don’t have to push it at all.

Turning the fuel is a quick easy test to see if that gets you going better

His EGTs in my opinion are abnormally low. It’s pretty fast to build boost from 2psi to 14psi, maybe four seconds. It is on full boost by 2500rpms max, full boost for Dan currently being 14-16psi. Does lack power a bit, seems like lack of fuel to me.

I put pedal to the floor and revved it high to see what EGTs do, seems to stay under 700* when you give it everything it has. Should be able to hit 1200* when giving it everything it has. Idle EGTs seem under 200*, very low to me, I shoot for 275-325ish at idle when tuning.

In my quick assessment, it needs more fuel.

Sweet 2002 HZJ78 with 1HD-T/H151F swap in for some maintenance before heading to South America.

I can attest to the fact that adjusting the fuel screw is directly correlated with the EGT's. I tuned mine until I can only put it to 1200F and beyond if ambient outside temps are around 85F and above, and I hold the throttle pinned for a long time. I also saw a slight reduction in power when I got to this point, and my boost is now 1-2 PSI lower overall (still hit 17-18 PSI max).

For me, this was the sweet spot between performance and safety/longevity.... play, test, play, test until you are happy with the results.

Sounds for sure like more fuel. 700 is really cool on fully mashed. Should have a lot more go juice in it.

I need to turn my fuel up a little more as well, I’m pretty cool overall on egt.


This is just cruising and giving the pedal a slight mash.
