The Stock turbo is only rated up to around 30 psi. After that the unequal drive pressure(60plus psi of exhuast back pressure to 30 psi boost) forces the exhuast turbine harder and harder into the thrust bearing then it squeezes all the oil out, over heats and self destructs. Here are pics of my trashed turbo

That damage occured on a full throttle run with peak boost of about 33 psi with a 1.0 exhaust housing. The turbo probably died a slow death but that run was the grand finale.

I bought my HX50 for $155 used on ebay. It will need a compressor wheel and I will have to built a mounting kit for it. Nobody really knows if a H2E mounting kit will work with it but it doesn't matter I am not paying that kind of money for a mounting kit.

Good rebuilt stock turbo's can be bought for $500-700 from Ron's turbo shop on ebay. Thats where my current turbo came from. Beans D66 is also a good option if you don't plan to go over stage 2 injectors but at the same time it still has the stock center section that still makes me nervous. The D66 has a larger compressor housing and compressor that helps even out drive pressure to an acceptable level but still move more CFM. It actually moves more air than a H2E will from what they say. But the H2E has been proven to be nearly indestructable at those power levels.

 

Ok, rated for 30 PSI. Good info but do you think I will ever get that high with stock injectors?

 

You should never see 30 psi with stock sticks. But it may be nice to plan ahead for PMS, and that usually brings new sticks.

 

Yea, know what you mean. We do a lot of overtime in the summer so after the bills are paid I just might be able to get some DIY stage 2.
