And here is a real RS Type RA in New Zealand







LEGACY RS type R & type RA

●RS-Ｒ
The debut of first Legacy was the end of January, 1989 (February 1 release). The turbo car was only sedan RS of 5MT at first.
In October, the same year, RS-R is added in accordance with a debut of GT which is a turbo car of a wagon (and 4AT version of sedan RS).
It is written with "a basic grade model of RS which is suitable as the material of a competition car for motor sports" and a new car commentary book.


RS-R、Ａtype
●RS-ＲA
　In November, '89 (December 1 release), pure competition car base for motor sports, RS-RA of a STi tune appear.Therefore the position of RS-R became considerably vague debut two months later.
It is written with a new car commentary book with "the order production RA memory model that executed engine fine-tuning same as the challenge car that 100000km speed records RS-R in a base."

RA seems to mean, 100000km speed record challenge "RECORD ATTEMPT" instead of RA of Rally.
(There is an opinion that RA means "Race groupA")

RS-RA put a fine tune to a rally and a dirt trial competition to be based on RS-R more.

As for the engine, forging piston and high resist pressure connecting rod metal are built in, and, as for the intake port and exhaust port, it is revised gap and polished up.
A crankshaft and the flywheel which got of balance are mounted the car with.If it is a beginner's class level, suspension is strengthened to the rank who can participate as it is.Variable ratio power steering is important, too.As for this, the steering gear ratio becomes quick.

Without close ratio transmission, it was announced as 100-limited model at first.Actually, seem to have continued job-order production of 20 monthly productions.
Long-awaited close ratio transmission was carried than a B type from May, '90, and increased with a catalogue model.

Engine specifications do not change from a latter period model C type, but ECU becomes 16bit, and a torque up in middle low rev .(be said by an emission control that became mild) and continued to exist to the last D type, and handed over a duty of RA of legacy to impreza WRX-RA with full model change-over, and the grade of RA disappeared from legacy.

Above is some info I was given a link to on the Internet.

Ok so here it is...... This is where the project turns
I bought a EJ20 engine that came direct from STI in Japan and was a development engine sent to the U.S.A the project never happened. It was said to be a works WRC engine.
The Subaru Legacy was on the road for three weeks at this point, and we were about to go to Indianapolis for the month of May so I could work for one of the teams for the Indy 500.
The Legacy was going to have bumper covers painted while we were gone, the person that was going to paint the bumpers decided to paint the complete car as he said paint match would be difficult, so after talking with my Dad regarding this he went ahead and stripped the car for painting.....
So I came back to a legacy that looked like this

22B05STI

Once I saw the car stripped for painting, I decided to go all out and Fit the EJ20 Engine, remove the Sunroof as it was leaking.That was really how this build project began, I started to contact people in N.Z regarding parts and continued to research The Legacys and that was when I decided to source parts and build a Legacy in RS type RA specs
I found that Original Group A Legacy roof vents were Available, so I decided that when I filled the roof panel, I would have Bruce Terry from Specialty Metal Fabrication who was doing the Filler panel, fit roof vents also.


Above is the Legacy dropped of at Bruces shop

22B05STI

Here is the Legacy the day I stripped the car out to a shell, I was already partially stripped out.
On A side note, the guy that was going to paint the car had just painted a Mercedes and It was a very very poor quality paint job, at that point I realized he was not a good painter, so I was now searching for a person to paint the car. It was disappointing but fortunate to find out before he painted my car.

22B05STI

Now for the next small disappointment, although not big, the EJ20 Engine the was from STI was not A full spec Rally engine it was amazingly an early RA engine with hand ported cyl heads, as well as a second set of bare heads ( not ported ) this same engine was actually in The Legacy RS Type RA. For this project it is actually much more suitable for my needs and furthermore amazing to have the correct Engine For a Legacy in RS type RA specs. Really it could not have worked out better.

everything i want....you has......=p

what an amazing build!!!!

Once the parts were stripped from the shell I spent several weeks removing the underseal and sound proofing material. This has removed a lot of weight ( the RS type RA does not have the underseal either )

22B05STI

During this part of the project I was working on a race engine for a Lotus cortina and I talked to the owner regarding his company (Kaminari) and he told my about Ray of DRC race craft and his Subframes, he bought one of Rays Subframes when he came to pick up his Cortina so I could take a look at it, which was before the first Sema show and I was very impressed with his work. I plan on fitting Front and rear Subframes from DRC to the Legacy.

22B05STI

Now the thread is nearly up to date, I had a friend of mine seam weld the Shell for me and I will be welding in bosses for WRC style car stands. I have also got one of DRC race craft front Subframes to check fit into the Legacy. This Subframe is actually designed for a Subaru Impreza however it has all the same pick up points as the Legacy.

This build is awesome so far. Thanks for sharing all the pictures.

So new Zealand gets that nice legacy and north America dosent?

22B05STI

New Zealand has so many rare and valuable special models that we dont have here, like the spec c rar, the s204 03 02 etc & the soberg edition impreza, all the rare version Legacys and foresters. The only problem I would say with them being so easy to find is that some very rare cars are used as daily drivers and not appreciated perhaps as much as they should be.

22B05STI

I have all the parts for my Legacy from New Zealand and also now have a Six speed from a 2001 RA Impreza with viscous center diff and Suretrac front and rear diffs. I have already stripped and cleaned the trans and rebuilt the starter that came with it. I have stripped and gone through the pump for the intercooler and cleaned up the radiator(cooler) for the intercooler.
Here's some pictures

This is the six speed RA trans that I am going to use, this is before I recieved it.

The box of parts shipped over from NZ including two new rear bumper covers (obselete in US) thes are shipped from japan to NZ and are different to USDM
One front bumper cover also from Japan to NZ
RS intercooler with all new lines and hoses
A used intercooler pump and Radiator (cooler) for intercooler
New coils. Used intake with wiring loom and hoses same as Rs and RSRA
A new RS type RA rear garnish


Top bumper is new USDM bumper cover, lower one in photo is JDM

New RA tach with higher rpm redline

And cooler painted

Starter repainted and rebuilt
