Hey guys I recently came into pocession of a turbo off of a Cummins ISL (8.9L) it a Holeset but I'm not sure of the model. I was thinking bout using this on my Chevelle conversion, but I know its a pretty big turbo. I am just not sure if an LS1 will be able to spool it up. I know that on the Cummins they are doing upwards of 40psi of boost at around 2200rpm. I thought that at bout half the size that the increase in rpms might compinsate.

Any input would be much apperiacated.

Thanks

Just through some quick research I think you might be looking at a Holset HE400 if it is a VG turbo.

Here is a site I found with a little bit more info.

Yeah you forgot your link, but its not a VG turbo. I was more wondering if anyone had any input on if its too big.

you shouldnt have a problem spooling it. really all depends on your setup. i didnt see what motor you are planning on running.just put a boost friendly cam in there and a stall and you should be fine.

Hey I found the tag on the turbo, it is a hx40w. It was hiding under a Cummins sticker. It has a 4" inlet and a 4" outlet. I have done just a little reading about them and they seem to be at least somewhat common on RX7s and Buttstangs, so I think that it will work fine on the LS1.

I have a Cummins 8.3L (500ci) @ work and the Holset turbo on that thing looks smaller than the 76 I have on my car.
