Truck Turbo

[FATAZZ]

Holset T04 off a Cummins truck, would this work on my rb20det?

[R31Nismoid]

its is very unlikely..

well... i mean, it would work. As in spin around.

But just not make any boost till maybe 10,000rpm

[boj01]

Depends on the ratios. I've seen diesel truck turbos produce 240kw@wheels.

hahaha.. i would love to do this to mine.. lol. just then i could say that my car is powered by a truck turbo :) thats awesome!!!

[Wazz]

would be a bit laggy.. better off putting one on a rotary or a rb30det but than again to see someone do it to a rb20 would be rather different as people normaly ignore the rb20 poor ole rb20

rofl truck turbos don't work? Of course they do...there are plenty of people running TD06 on these forums. In fact Roy has one on his rb20

Mate of mine put an new turck turbo on a GSR, didnt boost in 1st, started to boost by about 7,000rpm in second and mate about 185awkw, which lasted for about 2 weeks before it blew.

He now has a turbo suited to the motor and goes about 10 times better...

i personally wouldnt go near a truck turbo...

Little bit different tho isnt that Duncan??? Im not trying to be smart either, I just thought his would have been as any of the TD range on cars would have been changed to suit cars not trucks, even if their orginal reason of life was for trucks.

Anyway I still say they are turbos for low RPM work, and need big mofo engines to get them to work how they were designed to. And after you have to get manifolds etc made up, its probably cheaper buying a 2nd hand bolt on.

yeah don't worry about me, I'm just being a smart arse There are plenty of good, cheap car turbos out there, I don't see why you would bother with one not designed for a car.

Turbos are pretty much banded by CFM so if the volume of air going into an RB20 is XX amount to make the power you want and the velocity/volume of gas coming out is sufficiently matched to the turbo and the rev range you want power then it will work.

Now whether it will be laggy or give good response due to the construction is a different matter. Being off a truck it will probably need a large volume of flow to be happy, as truck engines tend to be large capacity long stroke slow revving things with the deisels have especially high compression ratios for compression ignition (no spark plugs). Also, being off a truck the rotating components may be of sturdy construction as response is not as important as longevity. May not be the case but something to think about.

also be careful as diesel exhaust temps are a lot lower than petrol temps, this being the case, diesel turbos can die pretty quickly as they are not designed for the high petrol temps ...

just my 2c worth

Truck turbos ule:thubsup:

I have a sneaking sus[icfion that a Cummins turbo will be too big...lol... sure would look tuff though:)

See HPI / Mart8in Donnon could only get 210rwks out of a TD06 on an RB20:(

And momentarily, until I looked at the time stamp, I thought "What alcohol soaked hour of the evening was this typed?" But it looks like he's just off to work LOL

yeah, but didn't the owner just want to stop at 200rwkw and not push it further for durability reasons?

so the boost was only 15psi just enough to get it into its efficiency range.

it doesn't say whether its a 10cm or 8cm housing like yours Roy?

:headspin:

Weak sauces:) My car loved the flogging it copped in April. Weak sauces, the ol Rb20 will put up with war more grunt:)

Yeh, feeling a little dusty from last night, so sorry about typos:(

[DoughBoy]

Been floating down the Dang river again Roy?

[FATAZZ]

is there any places in sydney that recondition/modify/high flow turbo's?

[GTRgeoff]

I love the smell of exhaust in the mornings.......sniff.........the smell of trackdays!!

[FATAZZ]

what could i use off this turbo to make it work on my rb20? i got this turbo for free,so its either modify this or get a rb25 turbo n hi-flo it.
