I don't know how to tell if it's a .63 or .48, without a code. It's a 5 bolt housing, but Precision does offer a .63 with a 5 bolt housing. ATP also offers a 5 bolt option on their GT30's. The threads related to the .48 all seem to be 3076 turbos making around 340 - 350 whp. This is a 3037 that made much higher than 350 whp. It was making 380+whp at only 20 psi. It could be a .48, but it doesn't seem to have hurt performance. That hp was with the MAF and XEDE tuning. I think an AEM EMS with speed density could make more hp.
