Me too! I love all the knowledge and skills that come together on this forum. Learn something new every time I sign in. And who doesn't love a little turbo sorting!?! Especially a diesel pig!
J Mack,
On your front shocks, is that a 45 degree fitting going to the reservoir?
Thanks

Hard to get a good picture but the 45° is on the shock and lets the hose stay up against the inner fender and out of the way of the tire..
Thank You! That's what I thought, I'm ready to order mine and I have the same setup as you in the front.

Ha…. That’s a really good question, just finished welding the tubes to connect the air cleaner up to the turbo and ordered a Hallman boost controller today. New turbo is proving a challenge to make boost at low RPM and keep it under 40 PSI at high RPM, if the new boost controller works as advertised then I should be good to go by the weekend..

Everything is hooked up and I hate it, with a hot tune it’s not bad on the low RPM’s but it’s stupid after about 2200 RPM and starts making brake $hit power all at once, like frame twisting, torque steer @ 70 MPH hard to drive power and nothing good will come from me driving it like that.
It has a conservative tune now and the power is manageable but low end sucks so I ordered another turbo and hope to see it next week.

Oh Man, makes 3, no?

The plan is to only use one at a time and parts not on the pig don’t count towards the final budget numbers, don’t think I don’t see what you’re doing here.
You think if you can get me to admit to something here you’ll have an ally when your wife discovers all those “Toyota” farm equipment receipts..
Edit: yes I’ve done the body twice, rear end three times, front end twice, drive shaft twice, tires twice, shocks twice and now the turbo three times all in 3500 miles, as they say owning a pig is tough love.
Thank you for clearing this up! So parts rigs, with parts not installed on the driver pig, could actually be subtracted from the total build budget?

That is exactly how my math works!
I know you'll find that Goldilocks turbo that will be just right. Such is the life of backyard engineering, just takes more time and more money. I've been through two versions of my first turbo, moved on to compounds, and now a second version on my small turbo in my compounds.
It does sound like you are getting set up for some compounds with all these turbos you'll have laying around.

That's funny! I can slip the " farm parts " by my Wife, but the tax guy always catches me.
It's called MUD math!
Did someone say compound turbos! I know the turbo you need might be out there, it sounds like you are looking for numbers that a single turbo may not deliver. Low end power on a low rpm Diesel engine requires a smaller turbo but the big boost numbers your wanting at higher rpm sounds like a big turbo...
Reminds me of this 450 hp 2.0L engine Volvo was working on:
Volvo tests triple-turbo 4-cylinder that cranks out 450 hp
Three turbos! One is electric to eliminate turbo lag at low rpm...

I sure hope the Super HX30w proves to be my "Goldilocks" before I run over budget on this project. I really liked the small B/W VFR-6258 and I think the super is similar but just a smaller map. Compounds are not an option in a 55 with all the other crap I have shoved in the engine compartment so I'll need to find a single that works for me quick or I might find myself looking for a one bedroom bachelor pad instead.
No compounds for this one unless I remove the A/C and one battery, I'm a Nancy boy so the A/C stays and I'll have to make the best with one turbo..
At the end of the day I don’t need compound power for this rig but I did liked the Idea of trying some different turbos to see if a single with a large map could get close to compound power/drivability, the EFR 6074 that’s on there now is close with nearly 45# of boost when it’s turned up but it’s really erratic power at that tune and would suck as an exploration rig. If I built a two wheel drive pickup I would run the EFR 6074 on kill and have fun driving the wheels off of it but it’s not a good match for the pig so I’m getting a smaller turbo and going to detune everything down to a reasonable level and hope to get another 3500 miles out of it before I need to dump a truck load of cash into it. At the rate I’m braking crap I might need to get a real job just to finish the pig..
I ran an HX30W on my 4BT powered 80-series and it spooled up nice and fast compared to the stock H1C. Just make sure you get the smaller 6 cm^2 turbine housing (not the 12). That coupled with 3.70 gears (and 35" tires) really lowered my highway RPMs without affecting performance.
David,
With the 3.70s and 35" tires, how was the low end, first gear performance. I would think the 4bt has enough low end grunt to pull it.

Thanks!!
I ordered a “Super” HX30W and it has the smaller 6 cm^2 turbine housing but a larger compressor wheel. It measures approximately 46mm inducer (intake) and 77mm OD.
It should work well as long as I keep the RPM’s down below 3200 RPM, looking at the turbine map and using 0.019 PHi for the super 30 drive pressure starts to climb faster than boost pressure at about 2800 RPM and by 3200 it’s past max.
Ron, the low end didn't suffer much going with the 3.70's. Overall, it kept the RPM's within the optimal powerband of the 4BT. Oh, I also had a 700r4 autotranny in that setup. It had a nice low first gear and overdrive.
