Is this a gt47-88??? Hey, i am not able to get measurements at the moment since i am away at school right now but i bought a turbo off a member here who said it was a gt47-88 well some people say they think the compressor wheel is to small for a 88. I was just wondering if anyone could help me out or at least tell me what to measure. I think its the air side of the compressor wheel diameter? I know its a t6 exhaust flange, 5" v-band exahust, and a 4" compressor wheel outlet. Any opinions are greatly appreciated. Thanks, Tim

Here are my pics, some of them have a yardstick next to the turbo:

Simple way of telling, a true GT47-88 is a 6 blade compressor wheeled unit and 10 blade turbine wheel unit. I'm pretty sure I know what unit you have since I just talked to Jose. He said that unit uses a 7 blade comp wheel and 11 blade turbine and is not a GT47 like the one you see in PSJ's album. He said it probably has the larger 1.23-1.45A/R housing off a DD.

I just had my dad check and measure, The compressor wheel has 7 blades and the turbine has 11 blades.

Its a TV based turbo off a Detroit diesel. Manufacture date would have been around 1981-1987 or so. Pretty old unit and doesn't spool to fast. As for GT47....I would tell him he is false advertising that turbo. Nothing GT47 about it...other then its big.

Thanks for the support, well he responded to my pm's and he said that he doesn't have the money to refund me right now but he is going to contact who he bought it from since he was told it was a gt47 88. I really hope he is not just going to give me the run around either. So i guess we will see what happens i just cant afford to loose $1300, that would probably cancel the build since im still in school and need to pay my next tuition fee soon.
