Pulled the head off, heres some pics of the inside

New injectors are pretty fouled up, this one was in the first cylinder. the others didn't look like this one, the others just had carbon build up.



Gasket came right off, some parts of it seemed like it was falling apart



Pistons looked good just dirty, you can still see the honing in the walls. Makes me wonder how many miles is on this engine.

 

Heres the fluid, it was purple fulid i got from checker auto parts, it was there fleet brand for diesels.



over all took 4 hours to take it all apart, wasn't to bad

 

Time for studs and valvesprings

 

finely got my M122 supercharger in, here's a picture of the charger next to the head gasket, this thing is huge!!!!



I got all my gaskets to put my engine back together, I'm just waiting to get my head back from H&H diesel. I'm having them machine the pedestals down, install the 60lbs valve springs and valve seals. Once i get it back ill be installing head studs, hopefully all this livens up my motor.

 

I am currently in the parts collection stage of a 4BD1T/NV4500HD swap (I actually have all the parts except for a decent turbo manifold) into a 2wd S10. Since these engines are very comparable, I was curious how you view the HE351VE on your 4BT. I bought a HE351VE for dirt cheap a couple years back and was planning on using it with the fleece controller. Since my application wouldn't need a ridiculous amounts of off-idle torque seeing as how my truck will end up in the ~3500lb range, I was going to go for a bit more horsepower than most, highlighting speed mostly. a rough, realistic goal of 250hp is where I am shooting for, maybe more down the line. All insight would be appreciated.

Excellent build by the way. I found you on youtube first and had to find your build thread because of the turbo choice on a 3.9. Great job.

 

my turbo is an upgraded HE351ve, its a 62/70 instead of the stock 60/70. The turbo is fun to drive but it has a huge lag, i can make 40+ psi pretty easy but its not reliable. Its more or less look at me, flooring it in 3rd and 4th. if you had twins or something to light up at lower RPM it would most likely be good. but i think its causing more issues then anything else for me.

I'm actually thinking about selling my turbo and controller for something else lol

 

Slowly making progress with my M122 supercharger, the supercharger is going to be bolted to 1/2" aluminum plate, then the brackets for the engine are going to be made out of 1/4" steel with slots so i can move the charger back and fourth to a line to the pulley.

 

That's just ridiculous :grinpimp:

 

LMAO i think most people think that when i drive by, this supercharger sticking out of the hood would just top it off.

So i talked to Turbo Technologies in Tacoma Wa. Turns out they worked on some GT500s with these and they claimed it can make upwards of 20+ PSI with the right pulleys. here's to hoping lol

 

ha ha that's awesome!

just get the sawzall out and make room in that hood!

what are the two ports on the driverside of the supercharger for? is it liquid cooled?

 

Its the vacuum ports, there's a total of three on the supercharger and another 2 or 3 on the elbow. I'm going to pull them out and tap them for a plug.

The GT500's have a water to air intercooler under the supercharger

 

Will be like a 60's muscle car with a GMC blower sticking out of the hood. Your idea about changing the turbo probably would be good. Go with something less complex like an HX35W or possibly an HX40W. Probably won't need the waste gate. Those turbos alone might be a bit laggy but since you'll have a blower up front that becomes no problem. With the right fueling you'd just touch the accelerator and it's gone. Hope she's got a good clutch.

 

might not look all that cool but its still going to be pretty awesome. the charger is going to be upside down so all your going to see in the hood is a plate and the charge pipping coming out of it.

 

That is really nice build you have there Steed. Did you have it running with the supper charge yet. How it performs?

 

Not yet, I have a machine shop machine shop making my engine adapters and cobra enginnering is making my adapter plate for the charger. It won't be for another two weeks before I get everything from them. I told both companys to keep templetes incase anyone else wanted to cop my setup.

The adapter for the supercharger is going to cost 255, and its made out of 1/allumium plate. The engine adapters are going to be made out of 1/4 steel plate not sure on the cost. Once I have it running ill have an idea on what the boost is going too look like. Jon bond performance might getnthe snout to make a custom pulley for the charger, I have a 2.6 pulley but I'm thinking I might want a 1.8 pulley and a custom crank pulley.

 

Thanks Steed,
Did you change the title to diesel yet? I am in process of swapping a 4bt into my 2008 Wrangler JKU. I live in Denver Metro area with emission test required. I would like to know if you have any problem registering your truck with diesel. Thanks a gain.

 

Na not yet, I was going to but colorado springs doesn't have emmisions on gas but they do on diesels. So its kinda pointless to do it right now. But when I talked to the dmv they told me all i needed was a statement of fact, need the form from the dmv saying what i did to the truck. Then go to the state patrol and get a safety inspection and a diesel emmison teat. Then take all that to the dmv and they will change it over.

 

Good for you, if they don't require emission on gas, you can still keep it registered as a gas engine then. How is the project going so far? any update?

 

Its comming my biggest problem is my turbo lag. Right now I'm working on supercharging it.

Here's the final drawling of the adapter for the supercharger. I should have it running by the end of the month. From what I read it should flow the same as a hx40, around 850 cfm

 

today i blew one of my boost elbows



Now heres the scary part!



Do you guys think this could be from revving the motor up with the 4k governor? I figure its either blown seals or high revving the motor is causing blow by, if its blow by is there a oil restricter i should be running?

 

Are you sure the turbo hasn't blown a seal?

 

no clue, the turbo is new with only a little over 1,000 miles on it

 

Wow, you really ripped through that boost elbow, lol.

Would a sudden decrease in boost, while under load, cause turbo over-speeding, which might cause the oil seals to go? That's a ton of oil in the intake so I feel like you would have noticed that much consumption.

 

Thats a scary amount of oil. Wherever that's coming form, if its in the boost tubes, I'd be concerned about runaway.

Dave

 

I left it disconnected, I'm going to start pulling stuff off and see how much oil is really comming out

 

Turns out since I've been driving around with that boot iff. I don't have any smoke when I come to a stop light. I thought it might of been a bad injector or something. Maybe I was leaking oil before this boot popped.

 

Well i have some dumb luck, the turbo is good. turns out the blow by was caused by a restriction in the turbo oil drain. I must have screwed the line up when i made it, my guess is some of the rubber in the line pealed back when i pressed the fitting in, causing the restriction. I had a new line made, and it fixed my smoke at idle and the oil blow by.

Its a lot more pleasant to idle at a light and not see pissed off people looking at me or worried about getting a ticket lol.

 

Good to hear it's fixed! What made you think to have a new return made?

Its rubber, talking to the local turbo shop it was meant for intake not a charge pipe.

That looks like one of the intake elbows that came with my motor, so I agree with the shop.

 

Just curious, was that elbow plastic or metal. Must have had some real serious boost to rupture that pipe. If that oil residue is in the intercooler you may want to flush that out. Probably will run a lot better without the oil backup.

 

Its rubber, talking to the local turbo shop it was meant for intake not a charge pipe.

 

Yeah, you need at least 3 ply silicone hoses in the high pressure areas. 5 ply wouldn't hurt. A company called Mandrel Bending Solutions sells the 5 ply stuff on ebay. Not quite as cheap as the 3 ply but darn near bullet proof.

 

Following this truck closely. Love the build. Get that supercharger on there and show us some crawling. Not too many hardcore wheelers on here, have you done any serious trails since the swap? Interested in how the center of gravity change makes it feel.
