So after a while, and beeing lurking around other members' build threads.
It's time i've started my own, and stopped stealing everyone else's threads.

My previously driven cars were:

-90 Opel Corsa 4 Speed 1000cc ( Grey :puke: )
-96 Suzuki Swift 1000cc ( red )
-97 Toyota Corola 1300cc ( red )
-90 Toyota Celica 1600cc ( red )

I'll try to keep it short and as updated as i can, limiting to the essential.


The car is a 2011 6MT Milano Red CR-Z, Which i bought used, with just 19.000 Km.
It's my daily car, and my first purchased car.

I've always had a passion for Japanese cars

Here's the only photo i have of it Stock. :iough:


I'll Keep here the current Setup and Mods:

Performance Mods:


- Garret GT25 Ball bearing Turbo @ 8 PSI
- Front mount intercooler
- 330CC Keihin CTR Injectors
- Custom Made CAI
- Hondata Flashpro
- Custom Exhaust Line
- Universal Catalytic Converter
- C-Blaze Trunk Spoiler

!!Everything else is pretty much stock!!

Total Cost, of Tuning/Material/Labour/Hondata
4200€





The car is making 201Hp.



And the end result:

With proper shifting, estimated 0-60mph, should be 5.8-6.2 Sec


Even though i couldn't find the conditions to do it yet, i estimate that this setup, will be able to achieve a top speed of about 280 Km/h ( !! Yet to be TESTED !!) provided enough sraitgh line, which is very respectable for this car.
SEE Minute 1:48 for 6th speed Straight line Acceleration




The car is very fun to drive, and it now has the overall engine power, it should have from Start.
- The current System Allows the Engine to make up to 270-300hp, However Pistons and Rods would have to be improved. For now i'll stick to this build and 200hp


Posting a few pictures of when the system was being built.






After a couple of undecisions, and going from one Garage to another, ended up replacing my exhaust tip, and painting a few accents and details here and there, sticking to this look. Although i have a few more goodies incoming.




Performance wise, like mentioned before, the car is incredibly fun to drive.
Maintaining all the IMA functions and assists, creates a good combination, of an eco friendly car, good MPG, and now packed with more performance.

Out of boost, the MPG is the same, as even though the turbo is small, it was tuned so that it wouldn't start kicking in until the 2500 rpm, allowing you to cruise discretely inside the city, without drawing much attention, but, as it is a small turbo, as soon as you pedal down a bit, the response is almost immedeate, not experiencing any relevant lag.
A small turbo together with the IMA assist, ends up giving you all the acceleration you'll need for a very good experience.

I will post around updates as they come up. Don't want to post a massive build
Feel free to post any questions regarding the build. :beer:

All the close friends that either tried the car, or went shotgun on it, Enjoyed it, a lot.

People who drove it stock, and now turbo ed, notice a considerable difference, even though stock, was already good.

I'm a simple guy, with taste for simple things, and I tell you, with this setup, I get everyday 30 minutes of total happiness going to work, and getting back from work. :D

I've seen some charts of k20 systems, and it looks incredibly similar, aside for the rpm, the horse power on the wheels, and the torque don't differ that much on what I've seen. With this route, at least you maintain the hybrid, and the mpg, not losing the CR-Z identity. just found this ( out of the 140 lbft torque the stock car has, 76 are from the IMA, so i'm still amazed at the 20hp little elctric motor )

If you look at the dyno run, you can see easily that at 2600 rpm, the car has almost it's max torque.

Like I've said in other scattered posts, after 2600rpm, it's all fun and games all the way to 7000.

Driving it daily You notice you always have more battery Because the car takes less time to accelerate, saving your IMA for later.

Even though I don't have any aftermarket visual mods, the sound the car makes, the color, the turbo, and it's uniqueness, makes it almost impossible to pass unnoticed.
It doesn't sound like a ricer, it has a nice tone. It definitely sounds bulkier, and more powerful. Now I can sure say, the power and chassi match together.

I'll be posting more stuff futurely,and more videos when the weather allows it.
Next step will be mounting my spoiler once it arrives, dipping some interior parts, and figure out how to customize the Oem hood, into a vented version of it.

Any questions, just shoot, and I'll do my best to answer them.

For automatic, and considering the clutch limit before it slips. I would go to 190hp, and an even smaller Turbo. That way it would avoid slip, and give an immediate response on the throttle, while keeping the rpm in the CVT sweet spot, below 5600.

That should give you the most efficient/enjoyable performance.

Also let me know if there's any info you would like added. I've only kept it short in order to keep it a light reading.

Thanks. I've seen @numberoneoppa kit and I loved it. I'd probably use the same one he's got. Would love a nice size GT like what your using but I understand I need to keep it safe cuz the trans.

Really tidy execution - well done.
One of the instructions I gave the builder, was that I would like it to look as Oem as possible, so even in a minute, he showed me what was going where.

The turbo is concealed behind the. Engine, and aside from. The custom Cai, there's not much viable difference from an Oem Bay. The intercooler is not visible from The bay, and if you look from the grill, "it could just be the radiator"
.


Whitebeauty, I didn't know numberoneoppa was doing turbo aswell, until Of recently.

I already have 7000km on this turbo, which is a lot for me, since my daily commute is of <30km. So far the turbo Behaves nicely.

I replaced the the oil after 6000km as it appeared darker than usual. But turns out the oil was still great, and I was just being over caring.

I now would love to test my theory, on reaching 280-290 kmh, however without suspensions and breaks, I really didn't find a spot to do it "safely", as even with the turbo it will take a while. But now, at least it has power even in 6th gear

Yeah @numberoneoppa had it in Ayumi and I loved the setup and everything about it... I think he's running a disco potatoe though.

Disco potato is the GT2860R/S, I've got the updated GTX2860R, which is a bit better and can support more power (up to 400hp).

In total miles, I've probably got something like 2000 on both setups, maybe a bit less. It would be a lot more except I have a bad habit of breaking things.

Aceryl, do you have any issues with throttle when tipping in? I get a bit of a stutter sometimes and so far I haven't been able to trace it.

Whitebeauty wouldn't have to worry about clutch slipping, by the way, as he doesn't have a standard clutch in the CVT. I think the GT25 size turbo is about perfect, though. I'm running this one as it still spools up plenty fast but will support me when I swap to the built engine (maybe by the end of the year).

PS: The welds on that exhaust piping are ****ing gorgeous.

What do you mean Exactly with stuttering?

Yeah, the 28 sure has more potential.

When i asked for what i what i wanted, i specificly said between 200-230hp, so the turbo was picked spot on. The only thing that took us by "surprise/naive", was the clutch, not beeing able to handle them.

Sadly most mods get super expensive here, because most of the decent stuff, is imported from US, and it sucks to bring them to Europe due to Taxes.
I would like to go to the turbo's full potential, but it will cost me about 5K extra, with Pistons, rods, clutch, breaks, retune and labour. And since modding isn't very friendly around here, even the turbo is illegal :\ ( crap law ), so spending even more cash, is not advisable here.

Regarding the welding, it sure is beautiful, however, one time, due to idiotness, i launched it cold, and the exhaust line separated from the Weld on a small bump. Turned out, my silencer was too heavy, and had very few support underneath, causing strain on the Exhaust manifold Weld points, which with pressure, and the bump, caused it to "break" right after the turbo exit. ( for a day i had a straight pipe, in my engine bay, the car sounded like a Ferry Boat ^^, it would take "ricer fart cannon to a whole new level" ). So i took that chance, to re do my exhaust line, and shove in a Universal catalytic converter, as the smell from the straight pipe, was a bit too much. Performance wise, it does feel the same, so, win win.

The guys that re did my exhaust, said the following.

-That weld looks amazing, however, as you can see on aftermarket exhaust, there's more "bent/turned" Stainless, rather than welding, as each weld becomes a weak spot.


Whitebeauty mentioned he tried or was in the car with your setup, how much are you running?
I find that for Stock suspension, breaks, tires and 16" wheels, clutch, 200hp is about the "safe" limit.

I wish I had a ride in it... Just had the pleasure of seeing it...

Haha, I promise not to break it this time! I'll have it down in a few weeks but I have some issues preventing me from taking it down quite get (O2 sensor issues and needs a retune). I should have my new boost controller by then, too. Right now I'm at 6lbs. Aceryl, I was at 8-9lbs before, dynod at 218hp. I agree with you that this is the highest I'd go on the stock motor.

Aye seems about right the 8-9. What did you mean before with the stuttering?

I'm satisfied with the current 8, just might need to be, fine tuned.. I was told the tune was a bit rough. But considering I drive normally, I might might save the tune to when I get a new clutch.

Your built engine will be killer. Although it's a bit too much for me $$$$

By stuttering, I mean when I put my foot down suddenly, sometimes the car will just completely cut throttle for a split second then resume accelerating. It's annoying. I am still getting a few sensed knocks so it could be related to that.

Which spark plugs are you using?

I'm using stock plugs.

The only thing that resembles to what you are saying, is Boost cut. It's the only time that the car seemed like it had a Hic up. i increased boost cut by1 psi Higher than what i was making, as sometimes there's a boost peak and that can cause the car to Hic up. It cuts throtlle, then it resumes again. At least that's what it sounds from my understanding.

is that it?



PS: Spoiler arriving Today. Was actually pretty fast. less than a week to get it from the US, looking forward to getting it installed, and to make sure the Fiberglass has no cracks...
