VF36 wastegate pressure = ? Anyone know?

Post by free5ty1e »

As I've asked here on NASIOC, anyone know what a stock VF36's wastegate pressure would be if I use the actuator that came with it?

Seriously, as I'm getting close to installing this thing, I realize I have absolutely no idea what my minimum boost will be. It may be that I will have to adjust the actuator arm such that the wastegate is always open until I get my FMIC and Walbro installed in the '91 (once it runs again, of course)...

Hey, I was about to post a new thread when I saw this one. How is it that you use the VF36? What did you have to change, if anything to make it fit?

I was wondering if I might be able to use this EWG housing to convert a VF34 to twin scroll?\\

It seems that if you wanted to do the swap the easiest way is to get the twin scroll header, uppipe, and downpipe. if you wanted to use what you have so far, you would have to modify a wrx/ss/sti uppipe right after the header and buy all sorts of flanges and get a bunch of welding done.

the oem or aftermarket headers and other parts i listed would be much easier I believe.

This isformation is based off images i have seen online, i have never seen a twinscroll turbo personally.

From the pictures I've seen, it looks like the downpipe would be the same, but the uppipe would be different. If I think about it, all I'd have to change would be the uppipe. However, I don't know this for a fact.

The downpipe flange is very different.

You need to swap to an 06/07 WRX/Sti oil pan, the full header and uppipe and the downpipe. The whole exhaust system is different, and the oil pan is different because of the twist in the exhaust pipes. Its not cheap. I put this exact set-up on my 05 STI.

And dont forget the 1mm hole banjo bolt for the oil feed line, or you will blow the seals out in a month or so I understand.
