I wonder how appropriate this turbo is for a 4AC. I had a Mazda MX6 Turbo with an IHI turbo, it would not start to produce boost untill 3000 RPM and thats with a 2.2 liter engine. It's only going to downhill with a 1.6 liter.

this thing looks real small for a 2.2...the inlet for the hot side is the same size as our oem downpipe

I don't know what turbo you have there, but that number you give is the model used in the MX-6, 626, and Ford Probe 88-92 (all the same car) and you said that it came from a Mazda 626. Those years have a 2.2 liter engine, the previous model had a 2.0 liter, and the I think the next model had a something bigger. From my experience with my MX-6 I would not put the turbo that came out of those cars in a 4AC.

ok so the turbo your talking about came on the 626 mx6 tbird etc and is labeled IHI RHB5-VJ11
mine that is for sale is a IHI RHB5-VF



49mm inlet
36mm outlet

44mm hot side inlet, three bolt flange
4 bolt exhaust side

Quote :
IHI RHB31
The smallest turbocharger we’ve seen fitted to a production engine is the IHI RHB31. This turbo is used on various Japanese Kei-class cars including Suzuki and Daihatsu.

We’re told this particular turbocharger comes from a Suzuki 660cc engine which, like all Kei-class engines, is limited to 47kW. Experience tells us this turbo can be wound up to more than 1.0 Bar of boost and about 75kW – but don’t expect it to last very long. These very small turbos aren’t particularly durable, despite having a water-cooled core.

The compressor inlet of this little ‘un is less than 30mm and the discharge nozzle measures 26mm diameter. A 2-bolt flange is used at the compressor inlet and discharge nozzle – there are no slip-over hose joints. The turbine wheel is fed exhaust gasses through a 24mm diameter passage in the triangular mounting flange. Three bolts attach the turbine to the exhaust manifold and four bolts connect the dump pipe.

The extremely compact dimensions of this turbocharger allow it to be mounted in very tight spaces. If you’re keen, you could probably squeeze a pair of these turbos under the bonnet of a N12 Nissan Pulsar/EXA turbo. Alternatively, you might have a small-to-medium size motorcycle you want to turbocharge...

IHI RHB5 VJ11
Another IHI manufactured turbocharger is the RHB5 VJ11, as fitted to the Mazda F2 2.2 litre engine. This engine is employed in the Mazda MX-6/626 and the Ford TX-5 cousin.

Despite displacing a considerable 2.2 litres, the F2 engine has a relatively low power output of 108kW. Not surprisingly, the F2’s turbocharger is quite small in comparison to other engines of similar capacity. We suggest the effective limit of this turbocharger is about 140kW.

The IHI RHB5 VJ11 draws induction air through a 45mm compressor inlet and blows it out through a 43mm discharge nozzle. A slip-over hose joint is used at each side of the compressor. Exhaust gasses enter the 44mm turbine passage and the 4-bolt mounting flange measures 74mm square. The dump pipe is a 5 bolter.

Note that the IHI RHB5 turbo is factory fitted to various engines and there are several subtle variations. These variations might come in handy if you want to mix and match IHI parts to create a unique compressor/turbine combo.

IHI RHF5 VJ26
We’re not 100 percent sure on the origin of this turbo but it appears to be from the Japanese-market Mazda Familia GT-R (essentially a STi or Evo equivalent of the Mazda’s Familia AWD turbo). The turbocharger is identified as an IHI RHF5 VJ26.

In factory form, the Familia GT-R’s 1.8 litre engine is rated at 154kW and the turbocharger is sized to give rally teams scope for more power. Two-hundred kilowatts is reliably within reach of this turbocharger. Note that the core features a ball bearing for enhanced boost response and strength. The core is also water-cooled.

The RHF5 VJ26’s compressor inlet is 45mm diameter and the discharge nozzle is 43mm (the same as the above RHB5 VJ11). We were unable to measure the diameter of the turbine passage because the exhaust manifold was still attached but we can tell you the 4-bolt flange is 74mm square. Note that this flange appears identical to the RHB5 turbo sampled above. The dump pipe also needs 4 bolts.

This is a great, medium-size roller bearing turbocharger. It’s a pity there aren’t many around.

Yeah, if it's not a 626 turbo as originally listed then what I said does not apply. It seems that the VF series are mostly off of various 80's and 90's Subarus. There should be a one or two digit number that goes after the VF that should from which one should be able what Subaru it came on originally. I would want to know that to see what the power characteristics of the original engine were if I were thinking about buying this.

mx_masta is correct. VF48's and most any of the VF's that you find on eBay that are still RHB5 are going to be from the 1.8L engine. The exception is ordering from outside the US or buying the 30 series which are RHF5 or RHF55

Ok is off of a 1.8 subie

That looks like a reasonable candidate.
