Here is a little about the real legacy RSRA
And here is a real RS Type RA in New Zealand
LEGACY RS type R & type RA
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.
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.
↑close ratio transmission, B-type
↑After minor change model C-type
↑Last model D-type
The engine & Transmissions are the same as RS.

I also added some decals to the instrument cluster which pays tribute to the old McRae 555 Legacy and STI. I have a new Tach which reads higher RPM as in the RA Legacy so I will have to re apply the decals but you can see how it will look.
I have been doing some projects for a local guy that owns a Subaru dealership, I fitted a small block Chev in place of a straight six in his 55
I have some Ideas and a concept to put forward to him regarding his Subaru dealershi and I hope to form a further affilliation with that dealership and hopefully lead to some interesting things in the near future. I will hopefully have some things to talk about soon
The Legacy is almost ready for paint, I fit the doors and new fenders and hood today. The seam welding is all finished and the jack stand mounts are now all finished
We will be making the WRC style stands as pictured, the mounts welded onto the Legacy are for these stands!
We expect moar pics!
First Mods: What to do and what not to do

"Isn't it amazing how smart you feel when you just aren't being stupid?"
This week was a big one for the Legacy project, I received all the parts from New Zealand so I now have the intercooler, intercooler cooler and pump ( cooler mounts in front of radiator, all new lines for the intercooler to the cooler, then all new coils, a rear garnish with RA badge, two new Rear bumper covers from Japan, and one new front bumper cover from Japan.
Also a used intake complete with all the fuel lines and wiring loom.
I also bought a six speed trans from a Japanese spec RA with Viscous center diff and Suretrac front and rear diffs. I have already stripped and cleaned the trans and fit all the parts back on it. I also disassemed the pump
For the intercooler and will post pics of these parts soon, the intercooler and intake and pump and cooler were all used, the price these as new parts are extremely expensive, so I had to opt for used.
Here are pictures of some of the new parts, the front bumpers in photo shows one USDM and lower bumper in photo is JDM
Above is the new tach fitted which is the same as the RA has with 9000 RPM
New panels on the Legacy
I will post more photos soon, it has been a busy week and I have not taken as many photos as I should, however I will take some more to update this build!
I have been making steady progress everyday, I gave the Six speed transmission a major cleanup and it looks really good now. I stripped and rebuilt the starter which came with the six speed and painted it again, I even managed to preserve and re use the decal. The intercooler pump has been re painted also and I need to get two metric o rings and it can go back together. I will try and take some pictures on Saturday of the engine bolted to the trans, It looks great.
I spent the last two days working on my intake manifold from an RS Legacy. So after milling of the unwanted mounts and hours and hours with a grinder in hand here's what I came up with.
Here's the gearbox, I am going to mock up and check all the fit of parts so there is still the engine build yet to be done
