|T in NE said: (quoted from post at 17:08:59 01/04/14) I have a 90. Please, come show me where to find the wastegate. We'll have a look at the boss' 96 as well. All the wastegate does is let exhaust by-pass the turbine so you don't over-speed the turbo. The 12-valves were governed to 2500 RPM, unlike the 24-valve at 3200, so it wasn't as much of a concern.|
I'll be happy to take a picture and post the one from my 97 12 valve.
The best upgrade is an upgraded waste gate. But most people like me put in a restrictive adjustable boost elbow to get our boost numbers higher.
The stock waste gate on 2nd gen 12 valves is set to 19psi on automatic rigs and 21 psi on stick shift rigs.
It is very easy to overspeed a turbo on 12 valves if you block off the waste gate completely. This post was edited by PretendFarmer at 05:13:33 01/05/14 2 times.
