To unleash the true potential of your 2.0T, the K04 turbo that is equipped on the Golf R / S3 is a much more robust choice than the factory equipped IHI (KO3) turbo, which runs out of breath mid-way in the RPM range. The HPA K04 Hybrid upgrade offers a higher operational boost range, while still working with the stock componentry; making for a natural and cost-effective upgrade. This K04 Hybrid conversion allows for a seamless integration, without the need for custom fabrications or aftermarket diverter valves. 

HPA has now developed our own high performance K04 Hybrid Turbo conversion that allows the factory K03 diverter valve to be installed in the OEM location, without a CNC port adapter. Our K04 Hybrid turbo assembly is one of the most advanced units available in North America, featuring many benefits over the competition.

With a market flooded with poor quality aftermarket clones and modified OEM assemblies, HPA has taken a fresh approach to supplying its customers with a K04 Hybrid Turbo for the Gen 1 and 2 EA 888 and EA 113 engines at an affordable price.

Reworked OEM parts result in high costs with no appreciative performance gains. For over two decades, HPA has been building hybrid turbines for the VR6 powertrain, working with the very best suppliers both overseas and domestically. HPA ensures the tightest quality standards are maintained in castings and the assembly of our proprietary CHRA's which feature a larger rotor and steeper turbine fins for increased tq delivery and rpm range.

HPA’s K04 Hybrid uses a newly cast compressor housing to incorporate the factory placement of the diverter valve. By casting the housings, costly CNC adapters and housing modifications are no longer required and associated costs and manufacturing time are removed from the kit assembly. To ensure a good result at first fire up, each HPA K04 Hybrid includes a new diverter valve representing the latest design updates from the factory.

Features:
  • Gain up to 355HP / 347TQ
  • Direct Replacement (in most cases)
  • Compact Design Allows for Faster Boost Response and Turbo Longevity
  • Turbo Muffler Delete for Smoother Exhaust Gas Flow
  • Simplified Design for Ease of Install
  • Diverter Valve in OEM Position
  • Block-off plate for PCV system (TSI)
  • Knife-edged, billet compressor wheel
  • Quicker Compressor Spool
  • Higher Output Across the Full RPM Range

K04 Bundle Options
As the factory IHI/KO3 runs out of breath at 5500rpm, the performance advantage of the K04 can be maximized by adding HPA’s Cast 2.0 Short Runner Intake Manifold. As the K04 pumps more air from 5500 RPM to redline, the HPA intake will support this demand by flowing 12-24% more air into each individual intake valves set. With the 2.0 Intake Manifold’s 42% larger intake plenum, initial throttle demand will be met with greater volume, allowing your software calibrator to develop more low end TQ. Take advantage of HPA’s race developed calibrations to fully maximize the RPM band of your 2.0T.


NOTE: IF INSTALLING ON B7 AUDI A4 - SLIGHT MODIFICATION MAY BE REQUIRED TO THE DOWNPIPE.

Needs editing
Format: Kindle
Cute storyline and promising characters, but the lack of editing is painful to read. I would love to read an edited version.

Baby bumps and bodyguards
Format: Kindle
Dark, emotional, and unexpectedly tender, Not Ready is an omegaverse romance that delivers found family feels, fierce protectiveness, and a very pregnant heroine who refuses to break. Vale’s on the run from a stalker, but lands in the arms of three private security alphas, cue the swoony tension, fake marriage twist, and slow-burn heat. It’s a little gritty, a little soft, and a whole lot addictive. If you love protective alphas, high stakes, and heroines with quiet strength, this one’s a must-read.

Strong Omegaverse Comfort and a Attention Grabbing Plot
Format: Kindle
Jillian West never misses when it comes to Omegaverse, and Not Ready is no exception. This story was the perfect blend of cozy comfort and emotional depth while still delivering a strong plot. Vale is such a powerful heroine, she is strong, capable, and determined but I love that she still allows her pack to love and take care of her. It’s that balance of independence and vulnerability that makes her so relatable. The relationship dynamics were amazing: Bishop is steadfast and completely head over heels, Mercy is skeptical but protective in his own way, and Holt is the hesitant one whose slow fall is so satisfying to watch unfold. The romance hits that sweet spot between insta-love and cautious build, keeping me hooked the entire way through. And that ending. Oh my god, the cliffhanger! I need the next book in this duet immediately.

Interesting
Format: Kindle
So I will say I enjoyed the story, for sure had its moments where it dragged but it was a great story. I really liked that omegas picked their alphas/make the pack. Normally the Alphas make it and the omega fits in with them which is great but I enjoyed this new version where all the power basically went to the omega. It was a nice change of pace. I can admit some of the weird bedroom stuff with her being pregnant was odd, it’s really not hard to do stuff when pregnant (I know I’ve had two and it’s normal and even encouraged at the end especially if you want the baby out). But I like the story as a whole and will read the second, I do hope the next one isn’t dragged bc it stopped being action or tense after she met her alphas and I don’t think it was brought up or properly done when they tried to do it. More sweet after she left.
