Another Holset TIII..

[rx2mazda]

I'm pretty new to "this" forum but i have been on the other one for a few years. Anyway..........

Okay, got the holset on and running It was not just a bolt and go affair. For those that are thinking about it, here's the low-down..........

Turbo is a Holset HE351CW off a 03-05 cummings 24V common rail engine..



You have to re-clock the turbo and cut off the WG actuator bracket thats made into the compressor cover. Obvisouly, you will need a TIG welder so you can reattach it where you like. There is a small pin that keeps the turbo clocked where you want it so, you will have to drill a new hole for it once you get the turbo clocked.

For the oil supply you will need a 12mm X 1.5 to -4an adapter for the turbo and then I used my existing fwperfomance SS supply line.The stock T3 drain bolts right up and is good!

If you haven't already, you will have to cut the back "ear" off the tranny. There is also a lead weight on the end of the shifter cable that needs to be taken off.(I don't see any use for it anyway).

Last is a bigger one. The bobble strut needs to be modified. I had mine cut down already for the 50 trim and I was only running the bottom bushing. I still had to bring it down. YES, THE COMPRESSOR IS THAT BIG Jackson gave me the idea of cutting the actual bracket so that you can run both Poly bushings. All said and done I removed about 1 1/2 inches and will run both bushing. Here's how it looks.....




I made a new upper IC hose........

hot out the powder coat oven.......


The compressor outlet is 2.75 so, I am using a 2.75 to 2.5 reducer 90.


Turbine outlet is about 3.85 inches V-band but, a 4 inch v-band will work. I am using a "Jackson Racing" 4-inch v-band to 3-inch DP and then back to my 3inch cut-out......In this pic you can see the firewall clearance, BTW I massaged it with a hammer a little....


Here it is all done..



Anyway, I did drive it a little but I didn't get on it too hard because I didn't have that tranny mount finished and the motor was loose plus, I was low on methanol. I got up to 20lbs and this thing moves. I pulled a G37 on the highway half throttle When this thing spools it sounds like a jet engine I am gonna tune my methanol and fuel tomorrow and get up to 25-27lbs. STAY TUNED!

that is sexy please keep us up dated

[rx2mazda]

Welcome! You'll fit in well, nice work

Thanks a lot!

He forgot to tell you all the turbo mods were done for him you know Way to let us do all the R&D and you take all the credit Haha,JK buddy,glad you got it together
This thing was an absolute animal driving around on the street. It was almost un-drivable with street tires(100 MPH,4th gear,27PSI,and let the tire smoke begin!) We drove it with BFG DRs on most of the time. Lets just say at a roll Evos,Z06s and some bikes saw the taillights of the "Not-Rod" Remember Carrol 400+ WHP and 12.50s or better before you even start to post results

HOLSET POWER BABY!!!

Banshee didnt have to mod the bobble strut bracket. I guess his turbine housing lifts the compressor farther away from the bracket. Might take my motor out, replace the freeze plug in the bellhousing and go beat up on his holset cause he is clutch handicapped lol.

What clutch are you using?

WTF? I have no idea who this guy even is!! LMAO. NO, you did clock the turbo and weld on the bracket but, that was the easy part I did mention the "Jackson Racing"(hint hint) downpipe. My car has so many of your parts I should get sponsorship, DP, Turbo, shifter......

That's probably it cause with the stock housing it sit really low. I wish i didn't have to modify it but, at least if i go bigger in the future i'll be ready

Clutch is TU 4-puck w/yellow plate. I'm gonna try to put my brand new M+H 23 inchers on and make it to the track Friday to see if she holds....

Nice bracket for the wastegate cannister!

I lack the ability to weld aluminum and I didn't want to farm it out so I made this plate from scrap stainless bolted to the "old" wastegate mount.





Concerning the clocking pin, I just removed it. There are allot of guys running these on fords and what not that run without the pin with no problem, and I didn't think it would matter too much. I did not cut the ear off the tranny, but I did have to modify the shifter cable bracket (lowered). I may also be pinching the speedo cable. But hybrids are a little different then the fancy lotus stuff concerning placement. I plan to go solid motor mounts, so I lost the tranny strut.

I'm also using the mitsu waste can, I didn't think the holset can has the ability to regulate around 7 or so psi, which is what I want to run when breaking in the engine and clutch.

Your waste can mount is Much more firewall friendly than mine.

I don't have an exhaust or intercooler pipes hooked up yet so I can't say what its like on a hybrid. Good luck if you make it to the track!

Forgot to ask,

What on earth did you use for the retainer clip on the compressor housing? I could not even find ring pin pliers large enough to buy, I ended up muscling it in with two sets of vice-grips.

Also, did you remove the silencer ring on the compressor inlet? Mines out, I'm all about that "jet engine" sound you describe.

I had to pick up a large 45 degree snap ring pliers from my Snap-On man. That worked perfect and you can actually remove it in the car

Yes,the silencer ring is long gone

Also,about the WG can,I tried a stock TIII can and I could get it to regulate boost hardly at all. I think with using the stock Holset housing you will need to port the crap out of the WG hole and help direct it a little better than it is stock. The way it is now I could get 27 PSI every time.

What are you using for an air filter? I don't see anything hooked up?

Guess I have to start looking for one for the van next year,

It's there, you can see it. It's a little mesh sock like filter that Jackson uses on his go-carts air filters. I want to get a good inlet filter going but for now that will do. It is going to be a pain running a 4-inch tube in that tight area. The heater core lines are right there.

Nice install, looks good!

[rx2mazda]

MBOYEK....that a nice idea with that bracket.

BTW, This thing pulls like crazy!!!! Lag is increase(obviously)over the 50 trim but when it comes on it is angry Once again, the sound of a Holset is ADDICTIVE.

[omni_840]

Nice work! Can't wait to see the number's it lays down

[turbovanman²]

You should post up a vid of it,

[Pat]

Any surge as boost/rpm's come up?
