MSR EK 1st build
Hi ,
we like to start sharing our race proyect.
Our first race car is an Honda Civic EK chassis. Is our first full-race build after some street-racer , track-daily tuned cars.
It will be a car for track-days/time attack and therefore we don't need to accomplish any regulation.
Chassis:
Our goal is to get a stiff chasis and good safety/weight relation. Capable of handle with the Dunlops slicks. All the bushings converted to spherical and some invention on the caster/width front vias. The driver position custom to our necessity and thinking on 2 drivers. All can we made on house.
- EK with MSR weld and MSR roll cage
- ATL fuel cell
- Lexan windows
- All camber/toe , LCA and balljoint by Hardrace
- Coilover system H&R RSS Clubsport , GP version.
- Front Legend 2pot calipers with EBC Ultimax 11" rotors and Ferodo DS3000
- Rear RSX caliper with 10.2" EP rotors and Ferodo DS2500
- New brake circuit without crossover or ABS and Wilwood proportioning valve on 1" ITR master.
- Front EK9 sway bar 26mm
- Rear DC2 Spec 98 sway bar 23mm
- All the weldings , reinforced and sway plates by MSR
- Our front bumper with some MSR splitter
- TC rear wing
- Dunlop 200/580/15 medium compound on 15"x7" bronze wheels
Engine:
We are looking for a power range about 200-230HP , thinking is a good number for funny. Since we must not fulfill any requirement for the engine, we have decided to use turbocharger for his better torque delivery. We have realized some Accord-turbo proyect and the results are superb. It's a Honda 2.0 engine with reasonable weight (SOHC) and the strongest tranny combo we can find. In adittion the spare parts are cheap and more realiable than the overvalued B - K series.
Our hope it's to work on E85 and maybe get 200-230hp on low pressure.
- F20B6 stock bottom from Euro Accord LX
- Ported Head by Jaas on stock Vtec cam
- Jaas stack manifold
- CR low to 9
- MSR motor mounts
- H22 JDM gearbox with LSD
- MSR oil cooler system
- Mishimoto Dual core from Accord
- Turbonetics T3/T04E 50trim Stage3 (76/54 comp 56 turbine)
- Some IC
- BOV Forge Motorsport with recirculation system.
- Intake MSR
- Waste Tial 38mm
- No exhaust , only downpipe to air.
- Ectune with PWM
Inside:
Thinking on 2 drivers any moment. So... seat for 2 and wheel for 2 (regulation)
- Dash MSR with S2000 gauge
- Modded steering column to fit our position , down 2" and 8" large
- MSR extensable wheel column.
- Recaro Pole Position with MSR low practicable mount
- Sabelt 6 point
- OMP 350 wheel
- Dash panel by MSR
Need to say we don't have any regulation or restriction to race , cause is an amateur car and the time attack regulation for us is Pro A , without any limit passed.
Hope you like and yours opinions.
Regars!

Re: MSR EK 1st build
Thanks dioxine , making all good our hands are capable.
The idea was to obtain a reliable engine on the 200-220whp with the powerband of a turbo engine. We made some engine builds on B , F , K and H series , and the best result for our K20 N/A model (250whp) is little far from any of the turbo builds with F or B series. Not only on the Hp number but the better torque band. And the ratio of HP/$$ is poor than turbo builds.
So.. the turbo idea was locked.
The other clear concept , is the displacement. For the same reason we jump to turbo-engine , we jump to the maximum displacement. So.. 2 liters is the choice.
Now we have a needing for 2 liters Honda engine , a power target and why not, a budget for the engine department. The tranny section is important too , cause some turbo-b16 racing on the time attack here, have tranny problems. The next upgrade on tranny will be jump to H/F series.
Adding the weight factor , spare parts capable , 3 units of F20-22 engines on the garage....
It's the best option for us.
Regards!

Re: MSR EK 1st build
So far it looks like you guys have done all your homework and all the pictures look really good. I don't see any problems so far.
Everything looks really good, like everything else, you will find out what you need once you start testing the car.

Re: MSR EK 1st build
Thanks man , it's our believe ... jump to the track and solve some dudes like the wheel diameter/width.
Most cars we see on this kind of engine works on 17 tyres and more grip band. But normally they use semi-slick tyres and with our Dunlop 15" slicks we have experienced temp problems (too cold) in some streetcar track-day we participe.
Mostly on rear tyres , and the fronts needs 2 - 3 laps to get hot
Can imagine on 17" , it's worse, we see..

Re: MSR EK 1st build
Big effort... 
Why didnt you put a full width cross bar on the center hoop from one side of the car to the other?
That will help keep the car from crushing on the passenger side in the event of a roll over.
Right now it only appears to be a harness bar and not giving you the full benefit of rigidity on both sides of the car.
Keep up the good work! looking good so far.

Re: MSR EK 1st build
You say the horizontal center bar???
The first use is for harness attachment , cause we using Sabelt short version. Maybe can help on the side crush too , but for the right side think unnecessary cause the car is only for the pilot , no passenger available.

Re: MSR EK 1st build
It seems to be a point of failure in my opinion.
When the driver's life is at stake you cover all bases, and not leave anything to chance.
An added 5-7 lbs is well worth the effort to save a drivers life.
That bar all the way across will be an added measure to keep the right side from buckling.
I see the bar on the bottom but thats not enough.... the middle of the car is one of the weakest points.

Re: MSR EK 1st build
Thiking the X desing on the central arch it's making that work.
To crush the curved part of the arch to the opposite side you need to stretch the arch. Physically the bar matherial can't compress enough to make the inverted curve.
So.. the X brace on the arch not only avoid the compression but stretch too.
Add the harness bar and the lateral platterns still for welding to the car pilar.
Thinking the pilot side can't crush easily than the car can run and hit , i believe.
The passenger side , have the same desing without the harness bar. But you need to crush the arch , the X, the lateral plates and the car pilar more than 1 meter to hit near the backet.
Clearly we don't get opposite to a safer idea than our idea, so..
Even this way... we take a look to it the next day on the box and study the matter.
Thanks very much dirty, I apreciate your contribution.

Re: MSR EK 1st build
Hello from Canada
That looks great! You guys seem to be doing very high quality work ...
Awesome choice on suspension and braking components. I hope all of your brake parts are compatible.
Looking forward to more updates!

Re: MSR EK 1st build
The brake matter is all plug and play for our Eks.
The european EKs with D15-D16 engine have 10.2" front brakes from factory , so , the 11" upgrade is plug and play with ITR/Legend/CTR calipers.
Rear combination is plug and play too. Our EK4 model ( with B16A2 engine ) have rear disc brakes from factory.
So... you can bolt directly RSX/Si rear calipers , here the EP3 TypeR model. These are for 10.2" rotors.
And the rotor from our EP2 (Civic 2002-2006 low engine model) is 10.2" with 4x100 pattern , direct fit to the rear EK knucle too.
taking advantage from the Honda mess...

Re: MSR EK 1st build
Some news...
After 1 month waiting for it, today arrive the coilover system. It's the RSS Clubsport version from H&R.
Liked the good technical support from factory cause they tell us for the car weights and suspension geometry to setup it.
The H&R people thinks 14kg front , 10Kg rear and 4kg front helper , 2kg rear. The strut setup is too set from they , and have one internal regulation.
IT comes all but top hats.
So.. we have old top hats from anohter suspension , the Sunk2 models
The final product
Now we need to find the good height setup and modify the steer rod to work without "bump"
Hope for the Hardrace package and will get all the suspension parts.

Re: MSR EK 1st build
Really nice looking build!
I would agree, not sure why you chose the rally style looking cage design but I hope it works out for you.

Re: MSR EK 1st build
Hi know, thanks very much.
i'd like you explain a bit of the design cage styles and what are the differences for the key points to chose it.
Really , we make the cage without catching any design in particular, only the design we think strongest with the minimum tubes and weight.
And thinking on circuit car, we re-weld and reinforce a lot of parts that in rallye matter you don't weld looking for more chasis flexibility.
Hope your opinion , it's very know-producing for us.

Re: MSR EK 1st build
Last work for 2011...
The engine bay is welded and the new shift column is done.
The work...
Now is time to weld the under-chassis
The shift column is bolted for remove in case of modification. Made in Cr-mo like the rollcage but in 10mm square tube.
Finding now some lightweight composite to close ii.
To have a wheel deep-regulation , will made a new telescopic hub in aluminium.
Regards!

Re: MSR EK 1st build
Hi Mosquito, can you tell me why you build around the shifter instead of leaving the shifter on the floor?, looks really good but what is the idea behind the design.

Re: MSR EK 1st build
Hi lwnslw
The shifter is attached on the ideal height for play it near the wheel. The frame part passing up here is to make a closed fiber/plastic panel and leave visible only the handle. All the shifter frame will be wrapped. In addition , this frame goes to the dash to catch it, because we have no dash subchasis.
For a hardness matter , we want to catch the frame to the front dash tube too.
