Default Ihi Rhb525 Vi55

I just bought a turbo on ebay and would like to get some more info on it but can't seem to find much, even on IHI's site. What is this turbo capable of and will it work on an EJ22? Was it worth the 165 with shipping I paid? Should I get a bigger one or another one and twin turbo it? The inlet on it is pretty small and I'm not sure if that's an issue when it comes to air flow. Any help or advise is greatly appreciated.

Hmmmm... not too sure about the ole e-bay turbo's...

Do you have all the piping etc. for a turbo on your car, or do you just have to turbo itself? Is the engine just an EJ22, or is it EJ22T?

Did you already recieve the turbo, or did you just win the bid, or buynow?

I have the turbo sitting in front of me but the only camera I have is on phone and we all know they don't take good pics. I'll take a few and put them on my cardomain site since I don't have one of my own. The engine is an EJ22 no T. I have an intercooler on it's way and as far as the piping goes I don't have any of it. I do have a BOV and boost controller. I'm still deciding on which turbo timer to get. The exhaust is going to be done by an exhaust shop since I really don't wanna get into changing the front engine cross member and pay out the a$$ for a new header. I'm not looking to spend a lot on this project I just wanna be able to climb up a mountain in 5th at 250+ feet per minute at 75-80 without having to dump it into 4th gear. I do live at near 7000 ft and most of my driving is at this elevation or higher. The lowest elevation I drive at is about 4400 ft and that's in SLC Utah. I guess what I'm really needin to know is if this turbo will boost to 6-7 psi without problems.

wrong flanges for subaru uppipe and down pipe, regular rhb52 would work but this is different. And twin turbo is a biotch.

I'm not worried about the flanges cause I will buy the ones I need and have them welded on when the exhaust is done. There isn't an up pipe that will bolt right on to the header that's on there now. I'm also gonna havta have a downpipe made cause I'm having the entire exhaust straight piped with no more cats to deal with.

I guess best way to test it would be to finish the project, and have it tuned, you'll know how fast it's spooling and where the power is then, hopefully it's at around 2.5-3k rpms.

Just be careful til you get it tuned.

neither the dp or up are suby flanges ... 3 bolt dp...suby only has 4 and 5 bolt patterns the turbo is not for a subaru the exhaust housing is not for subaru, y not just sell it and buy the proper turbo.

less fabrication.

I still don't know if this turbo will produce boost on an EJ22. I would go with a bigger turbo if I thought that my engine could handle it. The block has about 87k miles and the heads have 267k miles. It is still producing great compression and pulls about 20 inches of vacuum at 6700 ft elevation which to my understanding is pretty damn good. No oil leaks and decent lower to mid range power. The car has never had good higher end power for climbing at elevations above 5000 ft at speed. It is a 4 bolt UP and DP flange. Besides, I'm not going with a stock UP or DP. I'm going to have the entire exhaust custom built.
