Cheap Turbos From eBay On A 350 Small Block Engine - Cheap Ebay Turbos

For the carburetor to work correctly under pressure, you must add 1 pound of fuel pressure for each pound of boost to open the needle and seat. To do this, we used a boost-referenced regulator from Quick Fuel.

There are several ways to boost-reference the fuel-pressure regulator, but inside the hat is the most effective.

For the baseline, we wanted to use only parts we could make ourselves or buy off eBay. Solomon and Toki developed this adjustable wastegate controller that is nothing more than a brass block with a nitrous jet. The larger the jet, the later the gate opened.

To use the new gates, we wired the internal wastegates closed and proceeded to add more power with less boost.

This is the wastegate that saved the day. The Ultra-Gate 38s from TurboSmart are designed for entry-level turbo applications and fit the 1.50-inch outside diameter opening on our manifold. They are fitted with a 7-pound spring.

We also added a TurboSmart adjustable wastegate control. It's not that the nitrous jet didn't work-this one was a lot faster.

Overall, this was a pretty good system for the price. The placement of the turbos above the valve cover facilitates good lubrication, and it was easy to mount and route the piping.

The guys from Westside decided to go to Irwindale for some eighth-mile passes. Using the original tune-up, the car ran low 7s with the mph in the 90s. This was during a test 'n' tune with little time for tuning and no scientific way to know if the engine was lean. The mph indicated that it was. When we upgrade the fuel system, we should see 6s easily. That's 10s on the street using an iron-headed 355.
