Greddy Type RS Hybrid Creation

SHOULD be noted that I WILL NOT BE HELD RESPONSIBLE IF YOU #### THIS UP. DO AT YOUR OWN RISK

Well after finding a Greddy Type S Top and diaphragm among the boxes and boxes of parts, I decided to finish it off and install it on my Galant VR4.

First thing I did was to order a Knock off Type RS off ebay. Since I would be using the Type S diaphragm, I wouldn't have to worry about the diaphragm ripping.

Here is the Knockoff Type RS taken apart.

That diaphragm is literally built like absolute ass. I realize its a knock-off but it would seriously last possibly a month. Also if the Greddy authentic diaphragm is anywhere close to the same design, it would fail epically as well. I removed that crappy O-ring as the Type S diaphragm has that incorporated into the design.

Here is the parts that I had found in the box

Considering that the top was purple and kinda scratched up, I decided to just use the diaphragm.

Here you can see, that the diaphragm fits perfectly. I don't know who said the diaphragms are not compatible, but they completely are.

Here it is right before putting it together.

Now let's see some results!

If you assembled it with both springs, it's most likely going to be too stiff and will most likely surge on you. Those I've had dealings with were assembled using only the larger spring, and worked flawlessly.

Swapping to one spring now. Thanks for the heads up!

You'll still have plenty of adjustability using the screw at the top to get it dialed in.

The two springs are great for someone running a ton of boost, or someone with a ball bearing turbo who isn't necessarily concerned with surge as much as a journal bearing turbo user, but our cars simply do not have enough vacuum to draw open the valve properly and hold it open with both springs installed.
