The CR-Z modifications thread. Theories, ideas, and discussion.
The CR-Z modifications thread. Theories, ideas, and discussion.
The title pretty much says it all. I've found myself wondering for the past few days, wondering about what the future holds for CR-Zs and Honda enthusiasts. The car has just been released, and there's been a lot of buzz surrounding it for years. I'm looking at the big picture, which is the fact that this car is going to have a following, Hondas in general are pretty good at keeping enthusiast's interest for 20 years and beyond regardless of the model. The CR-X is 25+ years old and still has a large following, and people still manage to do stuff with them that blows people away on the track, the shows, or the message boards. When it was released way back when, it took a long time until we started seeing some of the stuff we do now. Just like the CR-X, the Civics, Integras, and all the others, the CR-Z will take some time to depreciate and wind up in the hands of the enthusiasts who build them for their own purposes. In the meantime, shops and racers with sponsorship backing, or the average Joes with above average bank accounts will be doing their thing showing us what's possible. There's threads here that already show, the aftermarket and the shops are working on this already, and it shows promise. But what exactly will we be seeing? Suspension, wheels, and cosmetics are a given. But what about performance, bolt-ons, forced induction, swaps? Are these cars even going to be reliable??? I don't think anybody has even stopped and wondered, will they be plagued with problems, recalls? So that's why I figured I'd start a thread like this, pretty much to serve the purpose of discussing modifications and ideas, what might work, what might not. My opinion: Bolt-ons galore for the first few years, no swaps yet. The car should work well hopefully and sell well also. The car is incredibly advanced in terms of electronics for someone to swap something like a K in there. How is anybody going to get all the fancy gauges and dash instrumentation to work in conjunction with something like a K series? That's a huge issue, unless you gut the car of it's powertrain and wiring to swap the K in with custom wiring and aftermarket gauges. Who has the guts to take apart a completely new car in order to do that? Let's see it happen! |
Re: The CR-Z modifications thread. Theories, ideas, and discussion.
i think installing a K-series into it and getting rid of the IMA would free up[ some weight and add some power. the bay should have enough room for one, if you relocate the battery and move the radiator up a little. then add a kpro, as well as suspension and more weight reduction. that's my idea of a sick ass cr-z

turn the battery voltage UP! LOL

Re: The CR-Z modifications thread. Theories, ideas, and discussion.
installing a K would be pointless. buy a brand new sport hybrid for ~20K then get rid of what makes it, it. and spend more money on another engine? ....yeah sounds great.

Re: The CR-Z modifications thread. Theories, ideas, and discussion.
Honda is working with Bisimoto on modifications for the CR-Z. dont believe me?
http://www.youtube.com/watch?v=EQvo9hwZdUY and http://www.youtube.com/watch?v=FdsFsPsD8l8 I heard Hondata has one that they are working on as well. The future is NOW! |
Re: The CR-Z modifications thread. Theories, ideas, and discussion.
The CR-Z has the L series 1.5liter. Torque biased low rev engines, moreso in Asia where they sell with the CVT versions. The Fit is the only USDM with the 1.5liter while the Civic hybrid and the Insight use the 1.35liter. The Fit aftermarket is a couple turbo/superchargers(max daily boost is around 0.8-0.9 bar on stock internal with 10.4:1 Compression ratio on Vtec versions), a few lower compression pistons, some chrome stuff, suspension. Not alot. If the CR-Z brings the aftermarket they'll probably be swapping stuff. If Hondata builds a tunerbox for the L15 they will probably be happy campers.
And although the Fit freaks probably think their hatchback looks better, the CR-Z looks a lot better IMHO. But don't say that to the Fit freaks :beer:. |
Re: The CR-Z modifications thread. Theories, ideas, and discussion.
Here are a couple of Japanese modified CR-Z's racing and a stock CR-Z racing the drift king.
http://www.youtube.com/watch?v=OeICaOu-WRw This is the 1st video I have ever seen of CR-Z's racing. They look pretty good. Just don't expect record beating lap times. I also heard that someone is making a supercharger for the CR-Z. Can't remember who. OH, NOW I REMEMBER! HKS is working on a supercharger for the CR-Z. http://www.youtube.com/watch?v=XQydT529Nfc for more info and specs go here: HKS Working On Supercharger |

Lets work with what we've got, a small 1.5 Liter engine AND an electric motor....the 1.5L engine is easy, but I have no experience with electrical motors, I think we also need to look into how we can generate more power from that... any hackers in the house? lol |

On the flip side, a more powerful electric motor could also provide more regenerative braking, assuming that the current one is maxed out under hard braking and assuming the battery could handle a faster charge. Or at least, that is what I gathered from my wife the last time I said "I don't want a hybrid, I can't mod one". Never try an argue with a mechanical engineer about what you can and can't do to a car... |
Re: The CR-Z modifications thread. Theories, ideas, and discussion.
To increase the power for the electric motor you either draw more amps and run high Current(C) ratings which would stress the battery pack or you install a larger pack. Assuming the batteries are high current already.
As an eg for upgrading the (Electric) Motor side of the car: EV components sells lithium phosphate packs for $44 for a 3 volt(nominal) with 40 amps at 1 hour (C) Current. They can maintain 200amps continuously or burst 2x or pulse 3 times that amperage. The CR-Z uses a 108volt(as an eg) pack and with 36 LiFePo cells it could generate 27.5HP continuous, burst 55HP, or pulse 80HP @95% Efficiency. All with 5x the capacity. The Motor would need to be reworked and the cells alone would cost $1500. It would take some work to convert the pack as the cells are much bigger than the D cells used in the IMA system and the voltage range is little bit different. It would add about 70lbs to the appox 50lb used by the NIMH pack. But considering they increase the HP by a good margin, the power to weight ratio is still much better than before. And since that 27.5HP is at 2krpm that's 72 ft-lbs + the 80 something ft-lbs from the ICE for 150ft-lbs at 2k rpm. It's a lot more electrical engineering than mechanical though. |

wait wait wait.... why would you wanna swap a K-series into the CR-Z, that defeats the whole purpose, if you wanna do a K-series swap buy a crx, civic, or integra and have your fun there...i don't know if i'm the only one that feels this way, but if i'm buying a CR-Z (which I am) and i'm planning on moding it, I wanna work with it's current system....i mean thats part of the challenge right? having a 500 Hp car that gets 40 MPG's... what i'm saying is simple if you bought a hybrid, keep it a hybrid.

Increased power out of an electric motor only involves adding more windings to the internal coil. Doing so would increase power draw (amps, not voltage), and probably require reprogramming the computer since it controls / balances the throttle plate and electric motor together for power delivery. This assumes the battery system is capable of supplying additional power as is, otherwise additional mods would be needed.

It's not the best setup, but it's still useable. Doesn't the fit have a similar set up? What about the first gen CR-X? Those have both been put to good use on the track. |

I'd also rather see what's possible with what the car already has, but some people are set on wanting to tear that out I'm sure. If the stock powertrain has potential someone will find that potential, if the chassis can be used for a swap someone will use it for that swap too.
Anyways, I'm glad this thread is going somewhere! anyway like J_Marc said, i like the input coming into this thread, keep it up!.... we got a lot of great info on how to increase power from the electrical motor... can't wait to see what the future holds for the hybrid tunning and racing genre.. |
Re: The CR-Z modifications thread. Theories, ideas, and discussion.
And to the people who think the K swap is pointless, there is one circumstance I can think of that would make it worthwhile, which is if you live in California. Hybrid vehicles are not subjected to smog checks.
K swap a Civic, try and get the car through a ref, still have to smog it every 2 years. K swap an Insight / CR-Z, mod to your hearts content... |

YES we all want to stuff a K series under the hood. most of us who have been doing this a while know..swap that single cam for a dual cam. sure u can boost a single cam and all that. but u dont get the kind of power you would get from a B or K motor with the same type of mods. so if u want to try to make the hybrid engine push out more power, have fun doing that. sounds expensive and i dont think you'll get much out of it. cus the rest of us are gonna put a K series under the hood and have PROVEN power that we know will put out big numbers. sure, the K dont get 40 mpgs, but that's not why we want a K motor in a CRZ. we want P O W E R and a light car. its the CRX all over again. going back to the roots of honda. BTW...the HKS video looks really fake. |

swapping a K-series is taking the easy way out, where's the challenge in that? |
Re: The CR-Z modifications thread. Theories, ideas, and discussion.
if i have my way, i will have three of these in the next 5 years.
1 k swapped time attacker 1 hybrid time attacker 1 daily driver cvt flushedtough, slammed, lipped the hell out. :thumbup: |

He is in the right thread, if you go through it again, the thread is about ideas, theories, and opinions about what could be done with CR-Zs in the future. Whether it's working with what the car already has, swapping something, tuning the suspension or whatever.... The thread never really was about getting 40 mpg's, I don't think any enthusiast in this thread really cares about mpg that much, if that were the case we'd all be leaving this thread. If you want to talk about getting the most mpg's, do like I did and start a thread. As for the roots of Hondas being about working what we have, that's hardly true, some people did go that route, but there's been swaps since wayyyy back, and that goes for Hondas/imports/sport compacts in general. As for swapping a K being the easy way out. It probably won't be easy and there will probably be plenty of challenges to be had to get it working. Buying bolt-ons and calling it a day would be the easy way out. |
Re: The CR-Z modifications thread. Theories, ideas, and discussion.
:agree:
^^he's right. its understood if you want to keep things stock and save money with the mpg advantage, but not all of us think with money in mind. we get a thrill out of building a custom machine, and when were done putting our foot to the floor and feeling our work come to our expectations. if thats not being enthusiastic about hondas, i dunno what is. |
