Super 53 question
I’m in the process of gathering parts for a build of my car and found what appears to be a reasonable deal on a Lindsey Super 53. My question is regarding the end of the shaft on the exhaust side. In the picture shown below, it appears that it’s been ground asymmetrically; is this intentional as part of balancing? I haven’t been able to find pictures of others with similar marks to compare.

I will also welcome feedback on the choice of this turbo for my car with the following criteria:
Build is for street/long distance gt use and prepping for time attack here in Ontario. Goal is 300-320 whp with: 1. 87 2.5 with 31k original miles (US car). 2. Running VEMS and a turbosmart Eboost controller, Tial 38. 3. Will be fab’ing a 3” exhaust. 4. Bolt on and being able to use the stock intake is important. I’m already sufficiently removed from stock suspension wise, so I’m building the car to participate in a non-stock index of performance category. |
one of the best turbos that I have ever tested, I think I have the most rwhp @ 16psi with the super 53

and in response of the marking yes that's standard on a lot of turbos and it's part of the balancing i believe |
Looks laggy as hell, from the other dynos I've seen floating around the net you can get the same peak power but a much broader torque curve from a super 48, or vitesse stg 2 sized turbo.

You may want to look at one of Speed Force Racings adaption of a Garrett GTX3076R turbo for your application. If you send him your hot side he can make it a basically bolt on situation. The newer turbos have a lot going for them, i.e. lighter wheels, improved bearings etc that lead to quicker spool and more hp through the entire spectrum.

I’m still looking for a turbo I guess and if I can figure out a mount, I guess I’m leaning towards a Garrett. In for a penny, in for a pound. |

I have heard great things about the GT turbos but have heard just as many cautionary tales about dealing with that particular vendor. Have things changed; can you rely on getting orders filled in a timely fashion?

The super 53 is ready to ship plus you get your 10% off as a lister. I tell you is a great turbo I have probably driven more 951’s with different turbos in one year that many of these guys in their entire life.

I changed my Vitesste stg 2 to a GTX3576R Gen 2.
But the vitesse was a super nice turbo, got changen since im going after 500whp.. |

it ain't happening unless you go the special tool road, I had a comp turbo triple ball bearing based on the Gtx35 on a 2.5L you will need about 29-31psi to hit 500rwhp @ 6000rpms, and then the head will lift inevitably.
22 psi And it Will do the power ;) |
