Suggestions & Opinions: Comp-R HX32 T28 7cm Hybrid Turbocharger
Comp-R HX32 500bhp 7cm T28 flange quick spool turbo. Not HY35 HX35, GT2871R GT28 | eBay
This popped up on my fb feed
Hx32 with a t28 flange? Sounds pretty good to me.

Compressor Racing Comp-R HX32 500bhp T28 Turbocharger
HX35 compressor, HX30 turbine, and a quick spool 7cm T28 flange turbine housing!
You guys asked for it, so we made it! After the huge success and proven performance and reliability with our previous Holset-based hybrid turbocharger, the RS341, which was in essence an optimised HY35, the way the ultra-rare HX32s from Holset Aftermarket rocketed off our shelves when we luckily managed to source some, and the fact we get asked if we have any HX32s for sale on an almost daily basis, we decided to produce another custom unit.
As anyone who's tried to source one by now, a Holset HX32 in any spec is a bit of a unicorn, known to be amazing, but finding one is next to impossible, as very few were ever made, and only for a few unusual OEM applications.
What a HX32 is, is very similar to the also hugely successful and popular in tuning HY35, but with a smaller turbine wheel (and usually smaller turbine housing, but not always) for even faster spool.
Basically, a HX32 is the compressor side of a HX/HY35, which is capable of 500-600bhp depending on which wheel, and the turbine wheel of the HX30, a turbo known for it's very fast spool, but limited by a slightly too small compressor to around 360bhp.
What we have here is basically our version of the HX32, using OEM spec Holset wheels (HX35 compressor, HX30 turbine, etc), of the best, well, most useful to the tuning scene, we've ever seen. What this turbo is, is this...
One of the smaller of the HX35 compressor wheels, still huge at 76mm (same as a GT3076R), with a 52mm 7 blade inducer, happily capable of 50lb/min+, but not so big it's a serious mis-match to the turbine like some 'specialist' hybrids out there.
The conventional quick spool HX30 65mm turbine wheel with a 52mm exducer (bear in mind a '560bhp' rated Garrett GTX2871R has a much smaller 54/47mm turbine wheel, this is not a restriction to the big HX35 compressor!).
Conventional HX30 oil cooled journal bearing core.
And a T28 flange, 7cm (A/R ~0.50) quick spool turbine housing.
This size (ie single scroll HX30 turbine and small housing) is well proven to hit full boost around the 3200-3500rpm mark on typical 2ltr engines, so this turbo is ideal for the guys that want the 400bhp+ people fit HY35s for, but want faster spool than the typical 4000rpm full boost performance that the common 9-10cm T3 flange HY35s give on 2ltr engines.
This turbo is suitable for anything from big power 1.3ltr+ engines, to typical 1.8ltr-2.5ltr 400bhp+ petrol engines.
Bear in mind the turbine is bigger than the standard CT15B turbine wheel on the 1JZ-VVTI engine (60/48mm) so won't be a restriction even on 2.5ltr 1JZ and RB engines.
And of course, two of these units would create a BEAST on 4-5ltr V8s as twin turbos!
Just like 99% of turbochargers in existence, HX32s were intended for diesel use too, and with this spec would be suitable for 1.9ltr-3ltr diesels, and the huge compressor means it's capable of big big torque.
SPECIFICATION-
Just like ALL HX32, HY35, and HX35 turbochargers, we HIGHLY recommend using an external wastegate with this turbo on spark ignition engines to prevent boost creep.

SPECIFICATION-
- Large alloy HX35 compressor housing (8in dia), with 4in anti-surge MWE ported inlet, and 2in (ID) v-band outlet
- 7 blade HX35 compressor wheel with 52mm inducer and 76mm (same as GT3076R) exducer capapble of 50lb/min
- Oil cooled journal bearing HX30 core with 360 degree thrust bearing and heavy duty shaft
- Quick spool 7cm HX32 turbine housing with a T28 inlet flange, 2.5in v-band outlet, and internal wastegate
- High flow 65mm HX30 turbine wheel with quick spool 52mm exducer (GTX2871R is far smaller- 54mm/47mm)
- Stunning looks, performance, and loud jet-engine spoolup sounds!
- Both compressor and turbine housing can be rotated 360deg to the core to fit any application.
- Comes complete with actuator, bracket, and gaskets.
Just like ALL HX32, HY35, and HX35 turbochargers, we HIGHLY recommend using an external wastegate with this turbo on spark ignition engines to prevent boost creep.
For me, it's always been about the turbochargers, and nothing personal. But like any human, we have our limits.

Sounds like a magical unicorn turbo. Would be interested to hear what people say when they try it.

The castings appear to be decent, quality really depends on where he's sourcing his internal parts from and the quality control during assembly. I'm just worried there's a large mismatch between the sizing of the turbine and compressor wheel. Could lead to funky performance.
