Hi there chaps.

Im after increasing my scooby knowledge and id like to know the difference between the RA R and STI (all classics) and if people actually know the difference?

Are they all the same power/ suspension/brakes?

I understand the RA has light weight bodywork and glass, close ratio gear box and quick rack. What about the type R? Is the track wider or lightened chassis clutch stronger diffs or gear boxes?

Just trying to spec up how much i can get my car to that spec with after market parts and how much ill never be able to achieve with my STI.

So any info, performance stats, or any personal comparisons between these cars would be ace.

Thanks for all the info SN

You would be better buying either typre r or ra the difference is so costly to change a sti.

The light weight body work is a myth. Most imports have an alloy bonnet. That's the only light weight bit.

For factual info on the Ra go to Type-RA.co.uk - Subaru Impreza WRX Type RA, Impreza WRX STi Type RA, Impreza Type RA V Limited, Scooby V. Ltd, visit the WRX forum & Subaru forum

There are a lot of myths regarding lightweight panels,glass and variations of the Ra models...ie mythical 2 door Ra etc

ok cool.

I have the STi for track use everything is going to get upgraded eventually i.e. brakes power suspension.

So how much of a benifit would it be starting with an R or RA, and which one is best to go for? I love the 3dr look so RA woul dhave to be awesome.

Im sure some OE RA bits will fit onto an STI.

Whats the driving experiance of either like?

Do both have DCCD gear boxes and short ratio? Do either have any different diffs or just different ratio diffs?

Can you actually tell the difference on the track between the models?

What Rooferman said ^^^^^

KareenaBaby

type r has the shortest ratio gearing, i sat in one with 350hp an thought it was stupidly fast!

scoobyc

iTrader: (2)

been looking on there and the info isnt 100% clear. will keep looking.

Nothing is mentioned about the weights of the cars.

I guess DCCD and 3dr are the only improvements i would really want. It talks about helical front LSD however im not sure which does and doesnt have. does the sti4 have? sti4 v-limited?

Seems they all (sti) have the same powered engine.

RA Dunk

incorrect, the RA has the shorter gearing

RA Dunk

the RA`s varied in weight between the model years with the lightest of them being the earlier ones, the gearing also varied on them between the model years as well with the earliest ones being very low geared, between a Type R and a RA the RA is about 20 odd kilos lighter due to not having the usual refinements like elec windows, central locking etc etc

Its a minefield mate..........it depends on which version car and the various models.There are wrx sti versions and wrx versions and not inc all the limited runs.

The sti versions of the type r and ra have dccd and are similar(apart from obvious)The non sti versions dont have the dccd and have Abs etc.

The helical diff was only available on the later models v4-v6 and was only on the limited cars.....Ie the sti ra version 4 v-limited,version 5 and 6 limited.

This incudes the sti type r limiteds version 4-6.

Generally the wrx ra(non sti) would have been the lightest of the bunch.

Working out the various models is not something you will learn overnite...lol

nathanstone

only real difference between these models and the sti is the close ratio gear box and dccd. not alot else apart from being slighty lighter. All classics run the ej20 block so have the same engines. Thats how i see it anyway! The RA is the impreza in its rawest form.

scoobyc

iTrader: (2)

So the RA is basically just a STI with a few bits removed and a differend LSD and DCCD?

Lets for arguments sake say im looking at a v4 type R / RA (have a v4 sti)

Does the heilical front LSD make a difference? i have not had any issue with spinning an inside front wheel on the track so i guess not. perhaps on launches.

I would like to see Top Gear Track style time difference between the 3 (sti4, r4 and ra4).

The gist im getting is that the gearbox is the only real difference between the bunch.

Need to find myself a type R with a blown engine and slap a sti in it! Im sure i read someone on here picked himself an engineless type R up for 1k!!

This is the one im talking about.

Wonder where i can find one for a grand!

I could just spend a grand on a DCCD box for my STI tho... That would make much more sense. I wonder if they are a straight swap?

EddScott

I have an V6 RA Ltd. Does mine have a helical diff and what difference does it make.

Gearing is quite low but its not too bad. Bit of a bugger on the motorway but I just drive slower - good thinking time on the motorway IMO

My RA has the same turbo as a V6 STI (VF29?) and its mapped too. Its bloody quick

Speed can be modded
Weight can be modded unless its lighter chassis or something.
Diffs i can live with. v4 STI has LSD rear diff anyway right?
Suspension can be modded unless they have wider track.
DCCD can be gained for an expense. Need to see how the new setup changes the driving dynamic before i do something like that

Should have just bought an R/RA to begin with!

Will keep my eyes open for a buggered type R / P1 i think.. the extra 2/3k just isnt seeming worth it?

rooferman

iTrader: (6)

yes yours is equipped with the helical front differential.

WRX - standard car
WRX RA - less refinements, shorter gearing
STi - go-faster goodies & more power
STi RA - go-faster goodies & more power + DCCD

All the above are 4 door

Type R is 2 dr (276bhp, DCCD)

Quickrack was an option except on STi V6s where it was standard


DCCD isn't a straight swap, you need DCCD bit for the g/box, ECU, wheel & clocks. Depending on where you source it, you may need the whole gearbox/rear diff

Yeah also seen possibly new hubs drive shafts etc. Seem you can get the lot for about a grand.

Something ill have to mull over/reasearch for the future i think.

MY 93 WRX Type-RA Specifications

EJ20 1994cc four cylinder engine fitted with an intercooler water spray,5th injector, closed deck block and close ratio gearbox with ratios of:
1st: 3.454
2nd: 2.333
3rd: 1.750
4th: 1.354
5th: 0.972
Final drive ratio is 4.111:1

Horsepower is 240PS/6000rpm and torque is 224lb ft (31.0Kg-m) @ 5000rpm.
Model code is GC8A47D
Engine type is EJ20G DW1HJ
Transmission type is TY752VB3BA

The MY93 WRX Type RA is the lightweight competition model of the Impreza WRX which was designed for entry into Group N rallying.

The RA is the “hardcore” Impreza, which does away with “luxury” items such as:

Radio/cassette
ABS
Map light
Digital clock
Air con
Electric windows
The cabin sound deadening material was also substantially reduced. The weight saving due to these reductions was around 30Kgs with the total vehicle weight being 1,170Kgs.

Exterior differences on the RA were:

No side skirts
No rear wiper
No fog lamps
No boot spoiler
No underseal
Black non electric mirrors
Black door handles
The MY93 Type RA was only available in white or red paintwork at a cost of 2,108,000 Japanese Yen.

Acceleration for th early ra's as standard with 240bhp was around 4.5secs so goes to show what advantage there is in that short ratio box, even if it is at the loss of top end speed.

The wrx RA's basically were the lightweight version prepared for rally teams to purchase from subaru, as stated above. They came with a 5th injector, intercooler water spray, no aircon, leccy windows or central locking (all 3 of which were factory options so can be found on them, ally bonnet no sideskirts, non colour coded (ie black) mirrors and door handles, less sound deadening (not none!), short ratio gearbox and diff.

nathanstone

from 1997, WRX had the same power as STI? on paper all versions reached a max of 276bhp?

EddScott

I would say this owning a 4 door but I do wonder whether the "2 door tax" is worth the extra. Certainly they stand out more compared to 4 doors because most people will only see 2 doors or 4 doors not STI, RA etc etc.

I think a good V4 STI RA would make a cracking car. My RA is just as quick as an STI if not a bit quicker with the gearing/mapping BUT insurers only have WRX or STI. So my RA is a WRX and about £200 cheaper to insure. Its even £150 cheaper than my old UK turbo

There are 3 different speed steering racks on the classic impreza.

2.25 turn lock to lock rare as hens teeth true quick rack, standard on the 22b and Sti 5/6 RA Limited, optional on the Type R and RA

2.5 turn lock to lock, standard on the Type R and RA

2.75 turn lock to lock, standard on all the other models

The quickest was fitted to the22b, v5/6 sti type ra and limited edition sti type r.......it will have a sticker in the rear window.

The type r comes in both sti variant(with dccd) and non sti version(without dccd.)

Those quick racks use to cost 800 quid at one time you can pick them up new for about 250 now (one thing i may do in the future on my type R as the fast rack isnt as responsive as i would like )
Oh and the rear hubs are different on the type R to any other classic subaru, makes buying brake discs expensive

Tony

Hmm. wonder if i can pick up a quick rack off an RA then. I think i might have something wrong with my rack.

rooferman

iTrader: (6)

The 13:1 racks for £300 are from the newage models and have to be modified to fit.....the classic 13:1 (2.25 turn) racks are no longer available as far as i,m aware.They go for £300 second hand..........

Also the rear hubs are identical on the type r and type ra within each model version.......ie v4/5/6 sti type r/ra all have the R180 rear diff and have the 2 pot rear brakes.

rooferman

iTrader: (6)

Thers is also a 10:1 rack available from the spec c iirc....

TonyBurns

iTrader: (3)

The disc sizes are 290mm but the hubs are different on the type R's hence you buy rear brake discs for them, they cost a fair bit more than the RA's.....

Tony

PS Prodrive do a nice 13:1 steering rack but its about 1400 quid

rooferman

iTrader: (6)

They are the same.....unless the ra hubs had been changed for type r ones on my car....which is a version 5 sti type ra.

They have the same 290mm discs,same R180 rear diff,same drive shafts and the same rear 2 pot brakes.Why would the rear hubs be different on the sti type r when all the other components are the same ....?

The R160 diff is also fitted to the earlier sti type ra which are a cheaper rear disc....???

The Type r was first produced in 1997...........with the R180 rear diff.....
