What turbo(s) bolts up to Legacy turbo headers?

Jessie James · 02-28-2001, 07:01 PM

Any recommendations on a turbo unit that will bolt up to the Legacy turbo headers?

I've heard that only the IHI units will, but not Garrett or practically anything else. If that's the case, then what does one do to use that turbo? Make an adapter plate or get new headers or...?

Off topic - who the heck is IHI and do they have a web site?

But you'll need an RHB5, and I don't think they make them anymore

I have heard that any of the WRX IHI's will pop on. Might need a new down pipe.

Anyhoo its a snap to put on a different flange for whatever turbo you want, but the IHI's are top drawer parts.

I am pretty sure it is just a standard IHI turbo flange that is used.

Are these flanges easy to replace? Or does one put an adapter between said header and the turbo?

The Legacy header and down pipe will bolt directly on to a WRX turbo, the down pipe will will not bolt on to n/a mid pipe. There will be clearance issues at the intake.

The older RHB5 had a circluar opening 1.771" with four evenly spaced bolts around it at 2.228". The RHB7 has a rectangular opening with a split inlet (like a CT-26) with bolt centers at 3.248, and 2.755". I haven't seen one of the new VF series. Anyone have one they can measure?

JC Sports kits will bolt right up.

blaster88 · 03-01-2001, 05:21 PM

If you can get one.

Replacing the Flange should be easy for any fabrication shop. I recently made a whole crossover for a EA-82T in my garage.

Also SVXtreeme, only certain CT-26's have the split inlet. The MR2 seems to be the only one with the split inlet. The old Single turbo supra used a CT-26 with a single large opening. There are also other differences, but I doubt anyone cares. What came with the RHB7??

I am sorry, but Kevin, the JC Sports Kit will NOT bolt right up to the legacy headers. The JC Sports IHI turbo (which just so happens to be the legacy RHB52 turbo) will bolt right up, but the overall kit utilizes the stock EJ25 headers and a custom uppipe and downpipe; you should know this. As for the downpipe, I have my doubts that the JC Sports uppipe places the turbo in the exact same location as the legacy headers, so that would be out as well. I did not design the kit, nor have I seen it, so I may be wrong on the downpipe.
