Great fit and finish on this product which I’ve just come to expect from Riffraff! It fixes the leaking EBPV permanently which as a side benefit also makes the turbo reinstall easier than it was to pull with the EBPV pedestal (less clutter). You’re going to want not only standard wrenches and sockets, but also a combination of flex head and stubby ratcheting wrenches to pull/reinstall the turbo and pedestal. I also had a 2” torque adapter set and a 10mm swivel socket which i don’t think I could have connected up pipes without.

It should go without saying that if you’re doing this modification, you’re also replacing turbo/pedestal o-rings and if it hasn’t been done recently, rebuilding your turbo. Take your time and plan on it being more than a one day project. My ‘97 OBS with 275k on the original turbo took me 30+ hours of work to pull, rebuild, and reinstall (reinstall was less than 3 hours). But there was a LOT of cleanup and about half of my bolts required significant work to get out (some of which broke resulting in me replacing a couple extra parts when I couldn’t get them out with an easy out). Regardless it’s not a quick project.

Great high quality part. Tough job but possible for the average Joe

Can’t say enough good things about RiffRaff!
Perfect fit great price!

Everything went according to plan for the most part!!

One thing i would say is CHECK THE SET SCREW BEFORE YOU PUT IT IN!

I kept telling myself that i would during the rebuild and yet it slipped my mind in the 9th hr…. And so after two drives she leaked ALOT!
Down the transmission and down the driver’s side

At first I dreaded a pinched Oring….
But it’s nice to lay midship with 4 feet of extenders and a swivel on 5mm Allen!

And the success is all that much better when it’s just a set screw

All and all I should have set it up in the mill and plunged an endmill to fit a 1/2 freeze plug

Excellent product! The screws on me I should have checked it BEFORE! Hahah

Not the easiest turbo removal, but I am glad to know I will be leak from from here on out.

Good fit and finish, looks great under my new stage 1 KC Turbo I also purchased at this site too !
A whole lot easier to install than the original. Once I finally got entire project finished and allowing engine to idle for a few minutes checking around for possible leaks and such discovered oil running down back of motor all over transmission. Quickly lowered vehicle and shut it down. Inspected with mirror and found the Allen head fitting had oil trail at base. I had seen this fitting upon removal from packaging, but didn’t think or know about checking tightness. While using a 3’ extension, 2 wobble joints a 5 mm Allen socket, it went in about 5 turns until it bottomed out. Snugged it down, cleaned areas and double checked before leaving work, inspected after getting home after 20 miles and no other leaks found. That was the reason for 4 stars. I still think it’s a very nice pedestal. If a friend buys one, I’ll sure to tell him to check that fitting.

10x easier to install then the EBPV pedestal, however strongly recommend ordering the bolts to attach pedestal to turbo as there are 2 different lengths and mine were both same length (my original pedestal wasn't stepped, replacement was and required 2 short 2 long)

Not to say getting the turbo out was easy, but with all the other stuff I was doing, to include gutting the outlet to remove the EBP valve (cost $1.06 for 3/4” freeze plug), this only made sense and eliminated another potential oil leak area. You don’t want to pull this turbo off very often - time consuming and a test of ones patience.

Quality product and fixed my leak

Installed and lined up like it should. Leak free and no more issues with the back pressure valve.
