DIY Turbo Master

[mfgguru]

Well, I finally felt called to make a turbo master. It's been on my mind for a while, but you know how it is, sometimes you just don't feel like it. Anyway, I used the original wastgate actuator(why re-invent the wheel),
5/16 threaded rod with flat washers,
a 5/16 nut with nylon locking capabilities.
The spring I used was a 5/8 by .080 thickness, 2.5 inches long. I thought the long spring would make for better adjustability and response and allow good movement.
Didn't take very long and was really easy.
When I get to my lathe a work, I am going to make a centering carrier for the top and bottom of the spring to keep it cetered.
Set as it is, it peaks at 11psi and has a sustained pressure of about 5-6psi.
Tools used: Socket set, flat screwdriver, angle grinder, welder, drill and drill bits.
Hope you like, I know lots have already done it.
Cheers,:hat:
Mike
PS: you can see where my vacuum line failed. POS!

Very nice. You made it look really easy. Well done.

OK........I'm impressed. Man, I need to do that also!! I'll get to it yet LOL.

Looks good Mike. :thumbsup:

Nice job Mike. I did the same thing on my truck when I had it. I don't think you can find a better bracket for making a homemade TM.

Man i didn't think of using the existing bracket, i made my own.... Looks good

 

[ghitch75]

yes i'll be doin' that...nice job!!!

 

[DieselCash]

Good job! Cant wait to do my truck.

heres my home made tm and where i put my boost gauge,toggle for high idle

Nice job, Beagle! Neat and clean!

thanks,
also should mention to guys that want to make there own,i used the stock rod,just threaded the end

Its funny you said that putting a thread on the existing rod is what you did. I was looking at mine yesterday wondering if it would work, seeing as I don't have a welder at my disposal. Looks like I got no excuse now. :biggrin5:

i threaded mine 12/24 and put 2 nuts on it, i would go 10/32 ,cant get a lock nut for 12/24

Thanks for all the info. I had a heck of a time getting the old actuator apart - but here's what I got and it still needs a little adjustment. If you look closely, you'll see a rubber hose between the actuator lever and the angle piece - I broke the collar that holds the lever into the wastegate lever, so I replaced it, but wanted a failsafe-so I'm hoping the hose will temporarily keep the lever from backing out.

Looks good I'm new here and I was wondering if any one could tell me? Do I just plug the vacume line that I disconect from the original wastgate

Welcome here and Merry Christmas. Yes that's all I did.

Thanks and merry X Mas Everyone

Nice thread and very nice mod, very interesting! I'm new to diesel's and turbo's, I've read about turbo masters before and I assumed that the waste gate was still "modulated" with the turbo master. After seeing this I think I was wrong. The "TM" simply holds the waste gate open/close at a given amount? It doesn't actually modulate? The only reason you see increased WOT boost pressure is because of the increased exhaust?

Please correct me if I'm wrong. Very interesting!

Thanks for posting.

i did this with mine but i had to weld a threaded rod on, cuz the rod on the WG was not long enough......

Need to know some more about your vehicle, year & model as if it's OBD-II 96+ model year and S or F 8th VIN digit, just plugging it may cause codes.

Hi I'm new and I know this thread is wayyyy old, but I found it googling and the ONLY info that keeps this thread from being complete(especially for turbo newbs) is the answer to poptopjr's questions.

From poptopjr's post:

"The "TM" simply holds the waste gate open/close at a given amount?
It doesn't actually modulate?
The only reason you see increased WOT boost pressure is because of the increased exhaust?"

Now I personally think, atleast from looking at the pics, that the TM holds the wastegate closed until the intake pressures reach a certain point slowing the intake/exhaust turbines down thus causing exhaust pressures to build and forcing wastegate open. Is this correct?

My only other question is this: If the turbo gives random spikes of manifold pressure, would a blow-off valve release during the spikes, or does it require constant pressure to be held in manifold for a blow-off valve to release?

Thanks, and ofcourse I accept any/all flaming for digging this up....ofcourse I googled "how to make a turbo master for 6.5l" and this was a first-page find. You guys got alot of useful info for us googlers that creep around leeching info.
