Thread: GT28R Wastegate Vs. GT28RS Wastegate

I'm getting the GT2871R w/GT28R housing in a month or so , but which wastegate is the most desireable?

743347-1, or 743347-2

Are you talking about the actuator? Because if you are your going to have to ditch the gt28r one because the way its clocked it won't fit on a FWD sr20 motor . I am using a gt28rs actuator with a atp extension rod, which you will need and wolla! You will have a perfect actuator.

If you are planning on running higher boost all of the time i usually use the hks 1 bar internal actuator for a s13 and make a bracket to hold it on in a fwd car.

I like the turbonetics dual port actuator. It can be set to any pressure you want. You still will need the gt28rs bracket to make it work.

I will just go with the GT28RS bracket and actuator. I plan on going external at some point so it isn't a big deal. I just knew that one of them didn't work for fwd, just didn't know which one. Thanks guys!

Also, do those have an oil restrictor already? What size oil lines should I go with and what size are the oil feed/return on the DET block so I can order the right fittings. Which oil return flange should I use? What about the coolant lines? I am using all det solid lines right now...

GFD turbo coolant line kit = awesome.

a $4 restrictor fitting should be used. Better safe than sorry, and if the turbo has a restrictor built in, it's not going to hurt the flow of oil.

they do have a restrictor built in but I still run a external one.

Coolant line is solved, but what about oil supply and drain? I would like to get away from the hard lines.
