Waste Gate

[cuzzineddie]

I want to disable my waste gate. What do I need to do and what do I need to watch out for when it is disabled.? Is there anytime that I would want/need it enabled?

It'd probably be somewhat helpful to tell what year your engine is for the techs...

I have a 97 ps. 4x4 withnautomatic trans that was beefed up when rebuilt what they could and new torgue converter that the transmission tech recmended (I don't know the specs of either). I have added a 3' down pipe at the turbo to my stock exhaust system minus cat converter. Installed a LARGE trans cooler that when pulling my 30' fifth wheel seldom go past 170 and just driving stays around 140 verified by laser temp probe on pan (sender in pan) Have installed pyrometer to keed tabs on exhaust temp. have installed K&N air element.
I am just trying the little /cheap stuff before going to the higher dollar items

94-97's dont have a wastegate. There is an exhaust back pressure valve right after the turbo. Its basically a butterfly valve that the computer closes when the engine is cold, this helps warm the truck up. Many people remove the shaft and flapper to open up the exhaust. You will see lower egt's and some have reported more boost and power.

wastegate and ebpv do not do the same thing...i don't see why you would want to disable either...

first take your downpipe loose. Then find the little rod comming from turbo pedistal to the valve, it disconnects on the valve end. next there is 3 bolts with i believe 5/16 or 8mm 12pt holding the exhaust back pressure housing on turbo, remove them and take the housing off. Look inside and there is 2 rivets holding valve onto rod. Take a sharp chisel (with housing in vise or on sturdy work bench), knock rivets loose and pull rod out. to plug the hole i just took the welder and welded a plug in. Any more questions just ask.
