I'm jealous ... very very jealous 
that engine installation is car-porn on 4 wheels. Keep up the fantastic work.

Almost there, had it for a 4 wheel measurement yesterday, I have a couple a pictures of when I had it on the trailer.
I am working on the lighting and other cosmetic things now, I hope to get it finished in the next 10 days.
Hopefully I will get it to the dyno next week, to get the engine management adjusted, I will get back to you with a dyno plot.

Wow! Great looking car!
Tell us about that exhaust please! I am really curious!
Very quick build as well!
Tell us how it drives, too!

The exhaust is a twin loop muffler, I have chosen this design because of the very high flow combined with low noise. I don’t think that the muffler
that most people on here use will flow enough for a 2,0 litre engine revving to 9000 rpm, the S2000 engine loves a free flowing exhaust, the ideal
setup would have bin a 3” strait through resonator, but that would have bin way to loud, most tracks around here have a 95 db noise limit.
The exhaust I have on is a cheap 75$ Ebay muffler, but quality is acceptable.
I know that some will love the design and some will hate the design, I am in the first category.
The exhaust manifold (Header) is the stock unit, that I have modified to fit, I am a little bit nervous that this is going to rob a lot of power,
because the S2000 engine is very sensitive to the design of the exhaust manifold

Here is another update.
I have finished the build a couple of weeks ago, and I am now trying to get rid of all the small errors I have made, I have had some trouble with the
oil pressure on my drysump, overheating ECU and liquid gasket in the fuel line, these things have set me back a couple of weeks.
It seems that I have sorted these things out now, and I have today adjusted the engine management on the Dyno. The result is not what I have hoped, it
only made around 220 hp, I am pretty sure it is because of the modification I have made to the exhaust manifold, I have added 15 cm of pipe to the
primaries, in order to get it to fit.
I will tray to get one of the good Header builders to make me a custom exhaust manifold this winter.
Here is a video of one of the dyno runs, the sound is not to god because of the noise from the fan, but you get a good idea of the sound and power of
the engine: Dyno run
This Monday I will be at my first trackday at Knutstorp in Sweden, I will let you know how it drives.

That looks great! Very nice job!
Make sure you put the MNR logo on the nose before the trackday so people can check in the pits what passed them so quickly on the track
earlier...
Can you make some trackday videos, too?
Have fun and let us how it drives!

I do not have a bullet cam, so I can not make in car video, maybe I can get someone to film a drive by. Ill invests in a bullet cam later when I have
saved some money up again.
MNR logo fitted to nose
I have also fitted a Sparco steering wheel last night, it is 30 cm in diameter, 6 cm smaller that the S2000, much better size.
Here is the dyno plot, you can see that the power falls off about 500 rpm to soon.
The reason that I have been able to finish the build so fast is because that I have had 9 weeks of work this summer, where I have bin building full
time.
Thank you for the kind words everyone.

Had a great time at the track today. Despite some further problems with the fuel line clogging up (I am a big idiot using way to much liquid gaskets
sealing the fuel level sender) I did get a lot of laps in the car. I must say that I am pleasantly surprised, it did only take me about 20 laps to get
a good feel for the car, it is a easy car to learn and not a lot of over steer as I have feared. The car is very fast, but not scary fast. It handles
the power very well, it dos not feel like it has too much power. It is a lot faster than a Porsche Cayman and a little slower than a Porsche GT3. It
is really easy to control a power slide thru the slow corners in 2. gear and because of the torque the engine has, you can be fast out of the corners
with out being in a low gear.
Only thing a bit disappointing was the brakes, they did not feel good. I have the Raceleda R16 4 piston callipers and circa 245x9mm non vented rotors.
I weighed the car the other day and I was very surprised that it fully tanked weighed 690KG, this is more than 100KG heavier than I expected, with me
in the car the total weight is close to 780KG. With this weight I don’t think the small 245mm rotors are up for the job, you have to use VERY hard
pedal pressure to get a decent stopping power, so much that it is hard to control the braking and it is impossible to lock up the front wheels (with
Proxis R888) witch I feel you should be able to do. I am thinking of upgrading the brakes to some vented 260 or 285 mm Wilwood brakes, combined with
some low temperature pads, what do you think? I am thinking of this kit:
Wilwood

Hey! Great update! I am glad you liked the car! Can't wait to get ours on the track...
As for the brakes, my first call would be Marc. Check it with him before investing in another brake setup. The Racelada are supposed to be pretty
strong, should be no problems locking the wheels, so there might be something else causing what you experienced as weak brakes. I would say try to
fiddle with your current setup before you spend money on another setup...
Not many pictures with your car on track! Do you have any?
Sort the brakes and next time you will be a little faster than the GT3...
Good job!!!

sounds like either, master cylinders incorrect way round or balance bar not adjusted correctly, or moving correctly

Marc, I have the front to the 0.625 master cylinder and the rear to the 0.7 master cylinder like it says in the build manual. Balance bar is circa in
the middle, the rear was not locking up under hard breaking.
The balance bar moves freely in the brake pedal.
There is no air in the system, the pedal is firm.
Would the extra weight from a bigger front brake setup, hurt the handling notably?
Don’t the extra 200kg over a light bike engine car mean anything for the brakes?
With a car as fast as this is, I would like to be confident of the brakes, even on a track with a short strait, the car reaches more than 200 km/h.

I have the long end of the bias bar towards the accelerator pedal!?
Maybe it just because I drive an Astra VXR as my road car and it has extremely good brakes, so it might be hard getting used to the feel of brakes
without a brake booster and lots of grip.
