Quantum turbo kit on 1NZFXE NHW20...Prius?

[JustDidIt]

Been on the forum for a while snooping around. Trying to find ways to make the lil Toyota hybrid a bit quicker. Yes, i know, if i wanted a race car, i picked the wrong platform to start from. I'm not looking for TONS of power but if I made 30-50 more hp, I'd be happy.

Started out by first making a custom MAF housing so I could create a different rather short ram intake. I got improved throttle response and really just a bit more noise.



Next was a full custom exhaust by first grabbing a DC header from a Yaris, removing 1 cat, resonator and all factory piping and going the 2" mandrel bent piping thru a couple Magnaflow mufflers. People were/are still quite surprised at the sound. Been told it sounds a bit deeper than a VQ at times.



After that came many suspension mods... really to many to list. Lets just say its definitely not stock and no longer handles like a typical Prius.







Always wanted to do the infamous Prius piston and 1NZFE intake camshaft combo. But from other sources the Prius ECU is a tricky one along with other Toyota's but has to contend and play nicely along with the High Voltage ECU. According to Toyota techs, if I added the Otto style 1NZFE cams to my Atkinson style engine, the HV ECU would read the lower RPM of the 1NZFE cams and throw a CEL within 5 seconds. I believe the code is P3191.

I then decided to get a "piggy-back" fuel controller that would allow for 30% more fuel by adding an additional injector pulse so that I could run E85. I purchased 1ZZFE injectors to help with the additonal fuel as they are supposed to be rated at 255/260cc and the 1NZFE/1NZFXE are supposed to be rated at 200/210cc. The kit allowed for manual control of the E85 ratio. The 'free' kit i received was faulty and I never got any type of timing control to help with advance the timing...so that died as well.





So I stuck with just monitoring with the Torque app. 40.1MPG is with heavy 19" wheels and "spirited driving".



Fast forward to the new year 2017...

A auction for a turbo kit that came of the Quantum hydrogen prius recently came available. The kit sat for months and never sold. I msg'd the seller when he first posted it for sale and asked questions about specifics and information. The seller knew little. After quite a while i made an offer on the auctioned item that was a 1/3 of the asking price and the seller accepted.

info on the original Hydrogen setup..back in 2006.

... about 10% of a Fuel Cell vehicle...We are just below 6 figures...

Hahahahah!!



Quantum apparently made about 30 of these cars. They were sold for around $95,000 as a government funded project. More recently, the kits are being removed and people are returning the cars back to stock. Thus, where this kit came from.

..and before I knew it, it arrived. The little Garrett GT1241. Tiny little guy. At some point, i'll prob need to make a new turbo header manifold and increase the diameter of the exhaust runners...but...one thing at a time. I need to get it running first.



Apparently running hydrogen thru the 1NZFXE made the engine lose so much HP, they had to turbo the car to get it back near OEM specs. The 1NZFXE is supposed to be rated at 74HP and the turbo kit with hydrogen managed to get it back to 70HP.

My idea is to run a low amount of boost that the Hybrid Synergy drive doesn't freak out. I then started looking into some sort of piggy-back system. After reading on here and all the mixed reviews, I found a deal on a Power Enterprise Camcon but was too slow on the draw and lost out on the deal. I then started on the wiring pin out for the ECM as they are different than most typical 1NZFE but was able to get thus far so that when another system came available, i'd be ready.



Then...another deal became available...and with my wife's blessing...i bought a Greddy E-Manage Ultimate for cheeaap. So now, i'm looking at the additional pins I need to figure out since the Greddy EMU has so many more wires. Even contemplated buying a 1NZFE boomslang harness and just swapping wires so I don't have to cut my own harness. This setup is still being determined. I've picked up a set of 2 step colder NGK plugs. I'll still need to pick up 1ZZFE injectors. From research, I'll need to boost fuel pressure and run a return line. I'm also looking at possibly having someone local to the Dallas Texas area install the Greddy EMU and tune the car....still TBD.

This is where I got a lot of my inspiration..a turbo NHW10. 1st Gen Turbo Prius.

But this is where i'm at on the install... its like it was practically designed for a Prius... oh wait... it came off a Prius. If anyone has advice... I'm all ears.
