Hi everyone. I have '75 Civic 1200 RS.
I changed strut for new stock parts.
but it shock is too soft.
and I want to improve brake and cam,carb,header...etc.

I'm looking for modification & racing parts
and used Mugen's parts in Japan over 10 years.
but still I can't find out yet.

Now,Japanese parts maker is not line uped for early Civic.
and I think almost not exist Mugen and other makers parts in japan.

Still I lookin'for racing parts of Mugen and others to overseas.

thaks.

p.s.
I messaged from Japan

I said How glad I am ! when I found early Civic loving people in the world.

By Richard Nasr (Admin) on Wednesday, September 15, 1999 - 02:42 pm:

Hashimoto, I have a set of quad Mugen Sidedraft carberators for sale for only $466 US dollars. Are you interested?

If you want to see a picture go to http://civic1200.hypermart.net/mugen.htm

By Hashimoto ( - 203.181.74.215) on Thursday, September 16, 1999 - 12:43 pm:

Mr. Richard,
Thank you for your reply.

I don't have racing parts almost. I have quad
Keihin CV carburetors with intake casting pipe made by Yoshimura.but I dont have air filter for the carburetors. It is my only one race parts. and still I don't change from twin keihin carb.because some problems.

I saw your nice Mugen carburetors.I am interest it
but I think difficult to fit to stock head.
How to fit to stock head?

And most I need is cam. It kind of Mugen or Yoshimura,and as same perfomance cams.

How good it is to hear from Japan that some of them still respect their ancestors i.e. the 1st Gen. Civics...its a Zen thing...you know?

By Hashimoto ( - 203.181.76.31) on Friday, September 17, 1999 - 10:36 am:

Mr. John S.
Nice to hear you. My English is not enough.
But I keep try contact to 1st. Gen. Civic loving people in English language.

Please tell me. What is i.e.?
Did you felt "Zen" thing from Civic?

By Richard Nasr (Admin) on Friday, September 17, 1999 - 06:04 pm:

Hashimoto, if you want a good cam I live 30 minutes from one of the best cam grinders in the world and they make a bunch of different cams for the civic. They are called "Shadbolt" cams. My friend Aaron knows the guys that work there. If you would like a good cam for about $100 in Canadian funds then I can get you a very nice cam.

By DrZOOM ( - 205.205.139.202) on Friday, September 17, 1999 - 08:43 pm:

Cams for $100.00?? Candian funds?? Richard can you post up some specs? I want to see what their like. I`m interested in cams at that price.

By (Civicguru) on Friday, September 17, 1999 - 08:56 pm:

Richard's Mugen carbs bolt straight onto the standard head. There are some firewall clearance problems but a big hammer will fix them. You do however need an offset distributor drive or run the distributor off the end of the cam or use a crankfire ignition system.
If you want a Mugen cam I know a guy who has the masters for the R1 cam. It would however be a regrind and a lot more expensive than the ones Richard can get.

By Richard Nasr (Admin) on Saturday, September 18, 1999 - 10:27 am:

I don't have the specs.. I had one cam from Shadbolt but the oil pump gear died on me partially because my oil pump was messed up. But it was a very good cam. It was somewhat mild. They do a wide rage of cams and actually have a bunch of cams for the first gen civic in stock. The price that I gave you was assuming that you give them your old cam. If you want to see their site go to http://www.shadboltcams.com

By Hashimoto on Sunday, September 19, 1999 - 02:46 am:

Thanks everyone,
Some kindly guys offer to me to get Mugen, and as good as other cams. I'm very happy.

I went to Shadbolt cams page, There are cams with low price. However I can't find spec for civic on them pages.

I would like to know some cams characteristics,specs, and whose impressons, about WEBCAM, Shadbolt, and others.
I think fat base circle of cam better than grinded small circle cam.
Almost racing cam need change to harder valve springs avoid to valve hit to piston on hi rev. Need I change to harder valve springs when I use these cams? Do you have experience of valve kiss at stock spring?

By Hashimoto ( - 203.181.74.214) on Sunday, September 19, 1999 - 04:03 am:

Is firewall as bulkhead between engine and cockpit?
Which do you like modified distributor type? In Japan,I can't see them for EB motor.Is easy to get them? How price? Which easy to install?

By Richard Nasr (Admin) on Sunday, September 19, 1999 - 09:37 am:

You can get a distributor that runs on the end of the cam for $500 U.S. It looks pretty easy to install but I don't want to pay $500 just for a distributor! This distributor doesn't use points. It is converted to electronic. You can get it from King-Motorsports.

By John S. ( - 208.30.162.64) on Sunday, September 19, 1999 - 09:09 pm:

Hashimoto,
i.e. means "such as"...or, "am example of"
How is the early Civic a Zen thing?
Due to its clean execution...the simple fitness of its form.

By Hashimoto ( - 203.181.76.29) on Monday, September 20, 1999 - 09:15 am:

John,
Thank you for your kindness,I think you also have Zen spirit.
and I respect Civic fan in many other country.

By John S. ( - 208.30.162.64) on Monday, September 20, 1999 - 09:39 pm:

Hashimoto,
Is it a problem obtaining stock parts from Honda for our early cars?
What about offical technical information...specifications etc...from Honda (in Japan)?
Are there many people in Japan keeping the 1st and 2nd Gen. Civics in running condition?

By (Civicguru) on Wednesday, September 22, 1999 - 12:48 am:

Yes, the firewall is the bulkhead between the engine and cockpit. The problem is usually clearance between the air filter and the lip that runs across the car near the top.
Angle drive distributors are next to impossible to find. About the only solution is one that runs off the end of the cam as Richard said, or use a crank angle sensor and a computer controlled electronic ignition.

By 2LOW2GO on Wednesday, September 22, 1999 - 09:32 am:

I have just purchased a quad Mugen Carb set-up with intake and air cleaners(still in the box!) It also came with the Angle Distributor. My friend is looking into building a billet copy...i will let u guys know...later Justin.

By Hashimoto ( - 203.181.74.214) on Thursday, September 23, 1999 - 09:53 pm:

Hi, everyone
sub.:Distributor and Quad keihin CV carb
You can get some modification parts, That is lucky for enjoy of car.
If my quad CV with offset manifold is not good,I would like to purchase a quad Mugen Carb set with computer controlled electronic ignition.
Now still I don't have put the carb on motor,I try to change the erectric fuel pomp from current pomp.Because my offset manifold doesn't hit to distributor but hit to current fuel pomp.

By Hashimoto ( - 203.181.74.197) on Thursday, September 23, 1999 - 10:35 pm:

Richard,
$500, It is high in price! more down to cost I wish.
By the way,please tell me size in jets of Mugen quad CV carb.

Civicquru,
I have seen some difference in name of parts,Thank you for your help.I have talking to RaceCraft staff.Is same as you known guy who has the masters for the R1 cam?

John,
Yes I have. and racing parts is almost not exist in Japan for early Civic. Next time, I try to get about offical technical information from Honda Japan.
In Japan,Two of 1st.Gen.Civic's owners club is exist.Them name are "Club SB1" and "CRC(Civic Road sailing Club)". about 20 RS civic is exist.It is minor in Japan. Almost they don't like racing modify.
2nd Gen.Civic is rare car than 1st Gen Civic.Because, I think many Japanese old car fan like before '70's car.

2LOW2GO,
Wow,Is it brandnew? You are very lucky.and you have good friend.
Let me know, impression of his made it.

By (Civicguru) on Thursday, September 23, 1999 - 11:08 pm:

I believe Charles from Racecraft would be getting the cams from the same person I know, but not 100% sure. The R1 may be classed as a mild street cam but it is a big cam. I'm not sure I'd want to use an R3 on the road. I've seen an R4 ... it was almost square! I think It's the biggest cam I've ever seen ... definitely a race only cam for an engine that will do 10,000 RPM or more.

By John S. ( - 204.120.50.1) on Friday, September 24, 1999 - 10:19 am:

Hashimoto,
My guess is, we would all love to see pictures of these Japanese home based RS Civics...I know I would.

By Charles on Sunday, September 26, 1999 - 04:38 pm:

If you look at the Racecraft photo page tomorrow you will see a picture of Tsuyoshi's RS civic. From what he has told me already there are significant changes. When you see the photo notice the front fenders (they are factory flared), they came out with 13 inch rims and look at the bumper assembly, different again. I assume the brakes were slightly bigger, but Tsuyoshi says the factory struts were also shorter! Overall this is one very nice factory civic, maintained in pristine condition.

By John S. (207.160.163.83) on Wednesday, January 17, 2001 - 06:46 pm:

I just saw a set of motorcycle Keihin carbs off of a CB1000(Honda), do you think they might be the same carbs as the Mugen carbs?
eBay# 540287222. I don't need them ,but...

By Tsuyoshi (210.159.218.198) on Saturday, January 20, 2001 - 07:40 am:

Hi John,
I was expected CB1000 carb fit for Mugen manifold.
But CB1000 carbs are not same as Mugen carbs.

Mugen carb is diverted from two set of dual CV carb for Honda N360,Z360,or Life.
They are Japanese old 360cc mini car.

By mariusz (203.134.17.8) on Sunday, January 21, 2001 - 04:30 am:

Hi Tsuyoshi

Are there any performance parts for the city turbo 2 engine in japan. Also do you know of the web site address to the honda city turbo club in japan, or of any japanese workshops that specialise in the city turbo 2 engines, (or kia cars). I need more power for my ct2 engine going in my 1st gen.

By John S. (208.188.193.136) on Friday, January 26, 2001 - 07:59 am:

Thanks for the quick answer Tsuyoshi,
I was wondering also, do you think that Mugen might still have, and/or be willing to part with the custom patterns they used to make their custom parts for the 1st Gen Civics? Such as the good looking finned camcover. or the four carb manifold, etc. I bet they didn't throw them away, you never know they might be willing to sell them.
Also, have you been able to find different jets etc. for modifying the internal specifications on the RS twin carburators. I'd love to have a list and part numbers for all parts available to service these carbs, and/or modify them.

By Tsuyoshi (210.159.218.197) on Monday, January 29, 2001 - 08:11 am:

Hi Mariusz,

Unfortunately,I couldn't found out about City turbo 2 performance parts, and workshops.
I find City owner's club web site but it was written by Japanese.

http://ww8.tiki.ne.jp/~suzuyan/index.html
http://ww8.tiki.ne.jp/~suzuyan/highlow/owners.html
If you want to contact to above club,
please send me e-mail.

I think Charles has many know-how.

By Tsuyoshi (210.159.218.196) on Tuesday, February 06, 2001 - 08:13 am:

Hi John,
Last year I was asked Mugen sales engineer about custom parts for 1st Gen Civic.

Unfortunately,
Mugen already throw custom part drawings for 1st Gen Civic. Therefore they can't make them again.
What a disappointing things!!

I still can't find different jets.
RS dual carbs has #88 primaly main jet.
My friend change it to #100 for Mugen cam.
He diverted jets from some honda motor cycle.
Keihin's Jet No.#100 means 1.00mm diameter.
Motor cycle racing shop was expanding jet size by thin drill. It is rare case.
Have you seen thin drill of millimeter units in States?

Now I use Quad keihin CV carbs with YOSHIMURA's
offset manifold. Quad carbs kit also made by Yoshimura. I'd like to modify jets, but I also have never seen some other jets.
I need some spare parts for repair and modifying.

I have parts list for civic. but RS carb parts
almost not available.

I think time has come that we start a campaign to collect signatures for a petition to reproduction of civic parts to Honda Japan.

Hi Tsuyoshi,
I think what you are talking about here in regards to Honda and other Japanese manufacturers would demand a "revolution" in the way they relate their current "work" ethics and attitudes to the "traditional" ways of the culture as a whole.
Sort of like when Nissan decided to create the "Figaro" and other designer cars. It must be viewed with a greater depth of vision than what the potential for cash profit and market sales might be for their efforts.
Line 2 of the 25th Hexagram...I Ching...
One must not count the harvest before one plants it. Each thing must be done for the reason of doing it, not for a perceived gain.
Another way of looking at it is in a quote from Andrew Carnegie, who at one time was the richest man on the planet. " If you watch the outflow, then the inflow will take care of itself."
(paraphrased )

By Charles (137.219.16.107) on Tuesday, February 06, 2001 - 02:43 pm:

Tsuyoshi,

We have special drills for jets. I can get you one of these drill kits (it is a hand operated unit and very cheap (the bits can be used in a slow speed electric drill as well as long as the chuck can hold them). If you get a spare set of jets you can play around with the jetting by drilling them out and if they are too big you can braze or solder them up and then redrill with a smaller size drill bit.

By John S. (207.160.161.239) on Thursday, February 08, 2001 - 02:02 pm:

I just found out from the Goldwing specialist shop here in K.C. that the standard main jet for the GL 1000 motorcycle carbs is a 120, and they said they can get 125's. Secondaries are 60's stock, but they say a switch to a 65 often works better on the bikes. I wonder what sizes are used in the RS version of the carbs and if this info is worth any thing or not.
