Not to sound like a noob but Im taking on the turbo project and was pretty much set on getting the hx35 with and external wastegate.

Now a friend of mine was able to get me a turbo off of a 2003-2004 Ford diesel truck. Its a rebuilt factory turbo. not sure if it's off of a 6.0l/6.3l/7.0l/ or 7.3l or if it was a F-250 or F-350

Was wondering if this turbo would be overkill or will it be fine on low boost?

I dont have too many specs on it. from what i got offline, i "believe" its a TP38 (Garrett). I have a few pictures of it and if taking measurements of the inlets/outlets would help any, let me know. I can provide those.


It's also some markings on the side that say ".58 A/R" on the cold side outlet, and ".9 A/R M3" on the hotside inlet. Also, its a V-band style flange

 

 

nothing wrong with that at all. HX35 ARE diesel turbos lol (Cummins 5.9L), a turbo is a turbo is a turbo. Diesel or gasoline

Also take pictures of the fans inside. All we can tell from the pics is the relative size of the housings, need to see the size of the fans (actual #s would work even better :-D)

 

holy **** that thing is huge!

 

hot:



cold:

 

holy amazon snails man!!!

hope your gonna upgrade the whole motor with that fat boy.

and whats with that c clamp... can you say dangerous!!!

 

thats what im trying to figure out. I dont want to go into my motor. I want stock internals so if this is too much, im getting rid of it. The c clamp is actually welded on in a few places and is about a 12ga clamp, looks like it was made on it

 

Im curious to what wheels are in that. Its big but i have seen smaller motors spool larger.

 

well i was comparing the turbine & compressor housing size to other turbos and it looks like the T61/P-Trim that nealco was using had a .96 turbine/.70 comp. so it seems to be a little smaller. would my comp. being smaller cause for quicker spools?

IIRC, the Powerstroke are somewhere near 60mm which should be a decent flowing turbo for a MAX. As far as spool-up, you need to keep the heat in the exhaust before the turbo and keep the hot side tubing diameter on the small side.

As far as diesel turbos, most big units were originally designed for diesel applications. The Garrett T76 in my car came from a Detroit Diesel. You just need to pay attention to the hot side a/r so that you can have decent spool.

 

so i should have about a 2.25"-2.5" feedpipe wrapped in heat/exhaust wrap? and 3" turbo back?

 

well if that turbine's AR is .96... that bish wont spool til quite high in the rpm range lol. But like Sabre said, keeping the gasses as hot as possible going into the turbine is the most efficient way to spool it. So yes, wrap those feedpipes into the turbo. As far as diameter, most people run 2" pipes out of the banks, merge em into 2.5" into the turbo, then out into a 3" downpipe.

 

what are you covering up in the pics?

either way you have to remember that on a diesel 6.0+ liter car that turbo would spool right off throttle aplication. It might take a while to spool on your car but it should hit pretty well. and it should be a pretty stout turbo, i would try and find how it runs in other similar sized cars before you mount it up.

 

yea, thats what i was talking about, after the 2 banks meet should it be 2.25 or 2.5". think i can pull off a 2.25" for a little more pressure in the feedpipe?


I wasnt covering up anything. just showing the size of it compared to my hand. I also have been trying to find someone who has used this turbo on a car but havent found any yet.

 

I PERSONALLY think its too big (the turbine to be specific). But since you have it already, screw it! Put that sucker on and find out for sure how well or not it works on the VQ.

Pioneers are ALWAYS welcomed, and so is the info they bring along.

2yrs ago.... "Rear-Mount turbo? HA! that's only for big V8s, that would NEVER work on a Maxima, bla bla bla"...... hehehehe is all i have to say

 

you better run like 5psi if you install that thing

 

I did some searching - while I wasn't able to find a map specific for the TP38, the GTP38 which is supposed to be just a little bit larger, is comparable to a T61. Assuming that info is true, the wheels would work fine for a maxima. The issue you're going to run into according to what i read is finding fittings appropriate to the strange sized fittings the TP38 uses. A .9 AR for the hot side is larger than I would put on a rear mount setup, not sure if you are doing rear mount with a lot of piping though.

 

yea, thats the same info i found. Thats how i figured it might work on the max.
Its going in the engine bay

 

On my Q45, I'm running a 2" feedpipe for my T-76 with a .96 hot side. I spool at 3500 rpms in 1st gear and at 3000 in the other gears. The turbo is huge; it weighs over 50 lbs.

Here are the pics:






I know that many think that you need to run a larger feedpipe, such as a 2.5", but it is not necessary. I would argue that it actually hurts you in most applications.

The bigger the pipe, the more energy that will be dissipated before the turbo. A small diameter feed pipe keeps the energy within the exhaust stream so that the turbo can exploit it to the maximum.

 

Thats what i though. That's why i was asking if i can pull off a 2" feedpipe. Wasn't 100% sure on it

 

Hmm, what's this? Trying to compete with our 62-1?

 

I got a 60-1 Hmmmmmmmm

 

To op.... that is a nice size turbo. My shop just got one in yesterday for a 2005 6.0 Diesel( over heated & killed the turbo).lol FYI The list price for this turbo brand new is $1300 $900 remanufactured with core return....The thing makes 500tq@2500rpms
The turbo has a built in waste gate actuater What will you use to control it?

To whom it may concern
I have a 60-1 too


oops nope..... Its a t61
Oh & a holset turbo the size of a basketball ......Really.
The holset is just for show though.lol

 

wow, i didnt know that about the built in wastegate. Any ideas on how to control it? Willing to trade for that t61 or holset(if its an external WG hx/hy35)

 

Nope but I will look into it next week. I do know that ford uses a pushrod type solenoid that allows for a max of 28psi. I could imagine a external wastegate should be fine but not quite sure yet.
Oh & sorry but I have similar plans for my t61. The holset is also a "keeper". I will take picks of the holset which is @ least 1&1/2 times the size of a hy35

 

You guys are NUTS with those things and I love it! I was originally going to use one of a 6.5 chevy diesel because I had a remanufactured one of the shelve. That thing looks like of a powerstroke. 2000 or so My dad has a 7.3 and turbo looks exactly the same. Don't count me on it. Im going with a GT35 on my 300zx which is all you really need and it spools so easy.

 

The 6.0 Powerstroke engines come a VNT turbo. That is what the actuator is for. If you can make it work, you would have a turbo that would spool up like a T28 and still make power like a T-60.
