man i have a good freind who put a turbo on his 02 si. it was a greddy 6 psi kit specifically for his car. he was running the emanage. he has about 30,000 miles. it has ran good for months. but here recently he got his oil changed and some gas station and on their old school lift he broke his down pipe. he drove home on it and pulled it to the mechanic who put the turbo in it in the first place. it sat at his shop about a month. mechanic welded it up test drove it. on the way back from the drive. it broke a rod! i dunno what caused this if anyone knows let me know cuz i dont understand.
