Synapse Engineering 40mm wastegate

[JNZTuning]

Fit and Finish
The 40mm wastegate flange is a direct bolt on to any Tial 35mm or 38mm wastegate flange which is a huge plus when upgrading from one of those (which was the scenario here). There were no fitment issues w/ the wastegate although it is a little taller than a Tial (35mm in this case).

Installation
Installation was extremely easy. All hardware was included (studs, locknuts, etc). We fitted the wastegate with the supplied stiffer spring which in conjunction with using a combination of the multiple ports on the wastegate eliminates the need for a boost controller. There are mulitple port combinations on the wastegate that will yield different boost settings. We chose to use the combination that yielded 20psi. Once tested, the gate held 20psi rock steady w/o any boost creap issues.

Price
Retail pricing is $285 w/o the flange kit and $325 w/ the flange kit.

Overall Impression
We are extremely satisfied with the product. It is a great alternative to the more expensive brands on the market. The wastegate has several options on it that allow me to say that I would prefer it over the other brands. With the boost control options and the fact that it holds rock steady at your desired boost level it is a huge benefit to the consumer.

We put one on a customers car at the shop (xenocron tuning) and I would have to agree, it held boost steady. I really like the feature of adjusting boost pressure just by switching which port you use.
