Must say this is a great thread!! I want to do this conversion too - 1400 heads and cam with the 1600 block. I already have the EA63 (1974 GL coupe), EA71 (1976 GL coupe) and a twin carb manifold for EA63. Just need to get organised!! Originally I wanted to keep the coupe stock, however I recently brought a 1974 DL sedan. One 'old lady' owner since new with only 85 000 Km, so might as well 'go for broke' with the coupe . Time to collect more stuff - gaskets and such!

If you have a look closely at the stage 1 (72-76) and stage 2 (77-81) they look almost identical due the same glass and basic structure being used, however, all body panels are very different both on the outside and the inside! There is no way you could mount the front end (guards, bonnet (hood?) and grille) of a stage 1 onto a stage 2 (at least not without a lot of fabrication!).

Yes I agree it looks ealier than 1974. The tail lights are completely different on 74 models, they are a little more 'integrated' with the rest of the rear end styling.

In the States only the 4wd versions had the same bumpers as Australian models. I could be wrong but I think all Subaru's from 1975 in the US had to have bumpers able to take an 8 mph hit (or something to that effect). This did not apply to the 4wd versions for some reason. Perhaps there were different laws for 'commercial' and 'passenger' vehicles like we have in OZ.

I have Japanese sales catalogues for 1972, 1974, 1975 (could be 1976) and 1977. All of these feature the RX coupe. The 1972 catalogue is just for the RX rather than ‘full range‘ versions like the others. Lots of racing imagery and photos of the 5 speed transmission and 4 wheel disc brakes. The RX would appear to be the top of the coupe line. The GSR and RX were sold side by side at the same time. The emphasis of the RX (certainly in the pictures) is racing. Options included what looks like an alloy sump guard and lap timer/stopwatch ‘thingy’ for the interior (not sure what it is called). The later 1600 RX (1977 catalogue) has no chrome. Very 1970s ‘sports’! In Japan there was also a sedan called a ‘Super Touring’ which had the same engine, 5 speed and 4 wheel discs as the RX. One thing I have noticed is the RX did not have the plastic cowl vent of the 1400 GSR/GL coupes, just the metal version like the sedans and later coupes (I think these tended to warp in the sun ). According to the specs the GSR, RX and the Super Touring sedan had the same engine (EA63S - From the 1974 catalogue), so the same power and torque. The GSR came in two versions, one with the 5 speed and one with the 4 speed. 1/4 mile time is listed as 16.8 for both GSR, RX and Super Touring. In the catalogues the RX had ‘RX’ stickers and side stripes while the GSR only had stripes. Hope this is useful!

I agree with the 'wrong' comment... Boy the AC takes up at lot of space, half the glovebox and no parcel tray! Still it will be nice to have if you can get it going! AC was never an option on Gen 1s in Australia (other than makeshift retrofit underdash types) Gotta love 1978, in terms of Subaru

When I put an electronic dizzy in my '78 I had to join the two wires that originally went to the ballast resistor together. Car wouldn't start otherwise.

You have the 4 spoke steering wheel? Make sure you disconnect the battery so the horn does not go off first, then push the horn pad down as far as it will go and twist anti-clockwise. It will simply 'pop' off. Then undo the nut in the center and remove the steering wheel. You might need some force for this, I usually find rocking and pulling at the same time works for me. Some steering wheels come off easier than others.

I would certainly be interested in a group buy - Gen 1 coupe x 2. There is an Australian eBay seller that sells rubber for Gen I models. Phil's Rotary's You do have to scroll down the page a bit. I orginally ordered the GFT front windscreen seal hoping it would suit a Gen 1 coupe but it was actually for 1979 - 84 models so I had it replaced with the 1400-1600 rubber. This seal is identical to the windsceen seal I purchased last year through the USMB. (Note the seller also lists front and rear for FF-1) I did ask the seller plenty of questions, unfortunately he did not know anything about them. Basically gets the seals from a 'supplier' and sells them. The point of this? Somewhere out there (Taiwan?) is a company that is making Gen 1 seals. Surely it would be easy for them to make the coupe rear rubber too?

My Dad and I removed and replaced the heads of my 78 wagon (It has an EA81) without removing the engine about five years ago. Yes you need to lift the engine as far as it will go and the battery tray needed some minor modification with a hammer to allow room, but it is achieveable. There is a bit of stuffing around though and if I remember correctly a lot of swearing about Japanese cars being too small for Aussie hands to work on by my Dad!

Nice wheels! The same as mine . Will be going on my coupe some day. They were made by Performance, the same company also makes the Superlite.

I like the white... Only because I want to paint my 74 coupe Orange! I have posted this on another thread but thought I would post it here as well: http://www.claussstudios.com/index.html Repro plastic and rubber parts. May come in handy for the pieces you cannot locate for your FF-1 Kostamojen??

I found the following while looking at Fuji Rabbit sites (There is one on eBay AU now: Rabbit) Repro plastic and rubber parts! Wish this was in Australia! http://www.claussstudios.com/index.html Just checked again and it states they also do 'custom urethane suspension'...

Shame the Konis are so expensive , as they are rebuildable and it may be possible to change/alter them to suit your application. That price would certainly buy a lot of other things for the FF1!

From what I can find out the 4 wheel disc brakes only came on the RX coupe not the GSR. I do not think Subaru exported the original RX (1972) only the GSR which had rear drums.

This eBay link should give you an idea: http://cgi.ebay.com/ebaymotors/Carb-Sync-for-Multi-Carburetor-TRIUMPH-TR6-TR4-TR3-MGB_W0QQitemZ360066179355QQcmdZViewItem?hash=item360066179355

It's just not fair! What is it with New Zealand and GSRs? Seriously, there is a tool called a carb balancer (or carb syncronizer) which is a vacuum gauge that allows you to tune both carbs. I don't think they are very expensive either.

Your rear brakes look just like 1972 JDM Subaru rear discs. Wish I could scan my 1972 catalogue but from your photos they are Subaru rear brakes.

The 1972 Subaru RX coupe (Like a GSR but more 'competition orientated') came standard with 4-wheel disc brakes in Japan. Also had the five speed manual. These brakes are, to look at, nothing like the later turbo models that people retro-fit. The chrome was toned down on this model too. There was no chrome in the window gaskets the windscreen wipers are also black. There were 'RX' stickers on some and a rear badge on others, depending on the year. The advertising brochure I have for the 1974 model pushes the 5 speeds/4 discs.My favourite though is the brochure for the 1972 model it states the following; FRONT ENGINE FRONT DRIVE/FLAT FOUR ENGINE/5-SPEED TRANSMISSION/4-DISC BRAKE HARD SUSPENSION/QUICK STEERING/BLOCK PATTERN RADIAL 155SR-13 (I love the block pattern bit!). Unfortunately the rest is in Japanese so I cannot read it:-\, but I can still look at the pictures!

My 1600 service manual states the following in bold; "The vehicle height can be raised by turning the outer end and inner end of the torsion bar by the same number of serration teeth in the opposite direction of the arrow mark on the outer end surface of the torsion bar. Turning the torsion bar in the arrow direction lowers the vehicle height. The changing rate of the vehicle height is 5mm (20 in) per tooth shifted" I assume the 1400 and 1600 rear suspensions would be the same. Hope this helps!

My FSM states all EA63 models had 3.889. Only the 4WD wagon came with 4.125. Of course things may be different here in Australia - emissons and all that.

Power up! Love the weber manifold (even the advertising is cool). :slobber:

After reading all my Factory Parts Catalogues it appears there a three versions of the EA63 (not including the different states of tune!); From 1972 to 1975 they had dual ports and wet cylinder liners. In 1975 there was a change to single exhaust ports but still with the wet liners. During 1976 and after engine # 914674 the EA63 had single exhaust ports and changed to dry cylinder liners like the EA71.

The two versions of the EA63 have completely different cams. The exhaust valves are on the outside for the dual port heads and on the inside for the single port versions. Not sure which heads are better but I have a 'Wheels' car magazine from December 1975 that states the following differences for the 1975 EA63 single port engine (refers to the dual carburettor models which the US did not get); Compression ratio changed from 9.0 to 1 to 10.00 to 1 Power remained the same at 67kw (92bhp) but was developed at 6400rpm instead of 6800rpm Torque also stayed the same at 107.8Nm (79.3 lb/ft) but was developed at 4800rpm instead of 4000rpm. Hmmm... From all that it appears the ealier dual port motor had more torque down low and was 'peakier' at the top of the rev range as well!?!

You may be better off checking out the following forum; http://www.ausubaru.com/ As others have noted the market is a little different in the US. I don't think they got '92 model Brats (Although I am sure they wish they did!).
