my friend gave me this turbo with a T04 .60 stamped on it that he took off a john deere tractor i think. it has some minor shaft play, and does need to be rebuilt. but if its worth it, then i could be boosting my gsr during the summer!

i was just wondering if it useable (once rebuilt), and what kind of performance i could expect pushing mild boost, with stock internals... or if its even worth re-building.
anyway, questions, comments, opinions welcome. now on to the pictures

 

Dont even bother. The exhaust housing is a massive divided T4 and will take all day to spool on your GSR. Unless you have a rotary, just toss it on Ebay and find yourself something else.

 

thats exactly what i said! i had the turbo stashed at a friends mechanic shop, and one of the mechanics said it was "the perfect size", so i took his advice, and thought i'd ask here before i did anything else with it.

would it be too difficult to attach a different exhaust housing?

Its a little more involved than that. The exhaust wheel is another issue. The housing is large and the wheel inside is large as well. Most times, turbos that come from Diesel applications, especially heavy truck and tractors, are nowhere close to suited for our engines. Sure, they're all turbos, but they're set up much differently for a large displacement diesel than for a sub 2.0 litre 4 cylinder.

It probably sucks to hear this, but it wont work. Also, you can tell the mechanic that he doesn't have a damn clue what he's talking about

 

i did.. he insisted that because a huge air compressor can easily spin it when aimed right in there, so could my car. i tried argueing with him, but... oh well.

not only that, but I doubt it's safe to rev that thing to our 8krpm redline whereas the motor it was built for huffs to like 2400rpm on a good day.

Lol, shooting it with compressed air. Sure it will spin, will it spin fast enough to make boost? haha. I wouldn't listen to him.

it spun decently fast... i mean you could feel the boost, but nothing too impressive. felt like normal air flow lol

 

It's not boost until it's above atmospheric pressure. You felt the compressed air from the gun

Yeah, probably more than fast enough to gall the **** out of the journal bearings and shaft without lubrication..

+1 vote for clueless statment of the year.

 

find some cheap t3 and put that t04 compressor on it

is it really that easy?

 

lol no

what's incorrect about it? You get a turbo that is made to spin at a certain internal rpm based on the flow/load of the motor it's mated to, you could easily overspin the turbo and get surge or increased backpressure in the turbo manifold.

The velocity of the gases exiting the engine at 8krpm is significantly different than that exiting at 2krpm.

care to explain why I'm wrong?

that turbo on a huge diesel will flow the same amount at 2,000 rpms (flow is relevant to compressor speed) as it would at 8,000 rpm on our motors

Think in terms of gas volume based on displacement and the answer will be clear.

how is it not that easy? swap turbine housings & wheels and have a diesel shop balance it.

Interesting.

 

i knew i shoulda researched FI more. i'm so lost... in my own thread!

The RPM of the turbo is what will give you boost pressure. Bigger displacement engines can spin a turbo faster with less RPMs because they physically move more air. Smaller displacement motors have to spin faster to spin the turbo's at the same rate of speed.

And those parts just grow on trees? Even the smallest .58 divided housing and t04 turbine wheel is too large for any street car, not to mention that compressor is only enough for ~300-350whp (s- or v-trim). Its not easy because you basicly replace 75% of that turbo in the end to make it a t3/t04e, and at that point, it will have cost more than a off-the-shelf 57trim t3/t04e (and make LESS power).

THe retard who told you it was a perfect match was only looking at the compressor. The cold side is great for a fast street car Honda (350whp), but the turbine sucks - it won't spool til 7k rpm on a GSR to make that power. 1k powerband FTL. But wait, there are guys that run straight t04b turbos. They are called diesel truckers and broke-*** HMT nogs with &gt;2.5L of displacement. The Honda guys who run turbos that spool up that slow make &gt;650whp (very different turbo).

BTW a diesel works with larger turbine housings because its always WOT. They can generally produce a couple PSI at idle, and a large turbine doesn't hurt spool time because they are always spooled up. Since they suck at upper RPM, the larger turbine also minimizes losses from backpressure near redline. A gasoline engine does okay at higher RPM's, so the turbine can be smaller to help midrange.
