Angel is hard to see best pics I could get blended them so the transistion would be a direct angel , but after running this 60 - 80 miles I pulled the head to take a look and the high presure injector had washed the carbon trail off the cylinder
At the ridge area about 3/8 of ridge was washed off of 360 degrees, left side of block were talkin about.
my thoughts are it is not pushing squarely on the top of the piston and it has to be harder on the rings / cylinder wall ? causing a hotter spot on that side. and the problem with timing would have to long gate the pump holes for more advance
whats your two cents on cylinder wall and could be or not on damage ?

THIS ATTEMPT AT CONVERTING A HOT PLUG TO DO WHAT DIRECT INJECTION CAN DO DOES NOT WORK

DON'T TRY THIS AT HOME

I just read the whole thing, that's an amazing work, actually you can use an arduino to control your glowplugs, variable vane turbo and other features you need and plan to add, I used one to make an auto glowplugs controller and so far so good :D, I could help you a cent on the electronics if you wish, just PM me.

Thanks! I was trudging along pretty good on this build until i bought a farm. I have my own business along with helping my dad with his businesses, and we had another kid so time has been the one thing i dont have enough of the past couple of years. I still have everything, plus i acquired another TD trooper that i plan on putting a 4jb1t motor in. That one would really benefit from the vnt turbo. I will indeed pm you about this!

Its funny, i actually thought about this thread just a couple days ago. Recently i sent a turbo center cartridge to get 3d scanned using a laser, i had the thought of sending one of my heads in to get scanned, from there it could be easily edited using computer software. Casting would still be the most difficult part, but not necessarily impossible. As of right now its still all dreams.

I moved away from "300hp" and would now rather have the most efficient powerplant i can get, along with having the ability to still get parts.

Wow, almost EXACTLY 2 years since i last updated, and 6 years since i started this. We bought a farm in ‘14, life and work got busy, then crop prices/ag market took a dump and things struggled a bit. Then July 26th of ‘18, my brother-in-law passed away. He was the owner of this trooper before me, and 1 of only a couple things left. My wife had a lot of memories with him in it, so its a put a big push to get this done.

Last year i picked up a 4jb1t from downunderyank, and am beginning the building process of it now. Thanks to 2sk8 i ordered the thermal ceramic coating and dry film lube. Im going to push this engine to 250hp so i want as much help/protection i can get.

I bought a 12mm pump head for extra fueling (stock is 11mm, c223t is 10mm), undecided on injector work yet.

I want to make clean, smoke free power so im going with a compound turbo setup. Calculations show ill need 38lbs/min of air at 40psi. The first turbo is a hybrid of 4 ihi turbos put together, ill detail that build later, parts are still coming in for that. Secondary turbo is a borg warner efr 7163. Both turbos will be ball bearing with a lightweight, titanium-aluminide turbine and should spool up quick and produce clean efficient boost all the way up.

I know the axles arent the strongest, but im not offroading or racing it, so with some throttle management i think it will hold up fine. Ill post some pics up soon.

Please keep us posted, this sounds like the ultimate 4JB1-TT build.

Thanks Jack, i will. Theres lots of other details that i need to mention, but its getting too late to write a big, long, pic filled post. As much as i know im going to enjoy this build, im looking forward to ending this now 10yr old project.

I like the idea of the twin turbo set up. The last MaxxForceDT had a twin setup and (the little bit of time when they do run decently) the response is just as good as a VGT...

Halden you are correct. Properly sized they cant be beat both in responsiveness and overall power. Sooo many people hear “twin turbo” and think your shooting for 1,000hp and drag racing. I could easily bolt on a larger, single turbo and still hit my hp goal, but i wanted it to be a clean, fun, and spirited driver, 3 words not normally associated with a trooper haha! As far as i know itll be one of the most powerful 4jb1t’s ive seen on a forum.

Anyways, heres some tech info for anyone else wanting to put one of these in their already diesel troopers, or pup if it would fit. From the factory they come with 12v glowplugs. Even though im modifying the engine a good bit, i wanted to maintain a seamless, factory feel, and i couldnt stomach the thought of cutting out the old wire harness and butchering-in a manual 12v system. So i spent a whole saturday researching glowplugs. I ended up having to download all the glowplug manufactors product catalog for austraila. Bosch listed this as the factory plug:
A904F51F-80EE-446F-B472-B154B81394AB.jpeg

Going further into the catalog, i found all the physical specs:
CE7F162C-7F59-4B17-9857-C7576B0B2878.jpeg

I know you cant see what all the numbers mean, but it tells you the thread pitch and size, overall length, heating element length, voltage etc. now that i had all the exact specs, i knew what to hunt for. I finally ended up on denso’s website, and downloaded their catalog and found exactly what i had been looking for:
79D4A1EA-8DD6-4712-A415-AD20653DE96A.jpeg

A denso dg-241 has the exact same specs, only it is 6 volts instead of 11. I could only locate them in the UK, and they are a whopping $35/ea. I ordered one to double check, and it fit perfect. Ill probably have to make a new bus bar, but ill be able to utilize the wonderful Isuzu QOS.

Up next will be making sure the idle up system is transferred over, and ill be happy.
