The 5th on a wrx is shorther than a uk 5th, the uk car had the longest gearing of all the impreza's followed by the wrx, then the sti and the shortest is the type r/ra,

SUBTYPER

So the WRX gearing might be a good compromise for a V4 Type R

Sideways, the way forward

Ahem!! .... P1

SUBTYPER

I thought the P1 was manufactured by prodrive and not Fuji Heavy Industries

Think it could be an option on the LTD.
I took my Typre R ltd out on Sunday to test this gearing matter. I was flat out at 8000 revs in 5th gear and was hitting 155 ish. No way would it get to 174 mph.
On releasing the throttle slightly I could hear a slight knocking from the front of the car the oil pressure started dropping and then the temps rose from 80 deg to 90 deg so I stopped the car. checked under the bonnet all ok but on restarting the car the knocking was much louder. I wonder what this could be.

All the 5 gears on Uk cars and STI Type R/RA's are fairly evenly 'spaced' with similar drops in revs when you change up. The final ratio is set buy the Diff/4th gear, with 5th being a Drop down..

In 5th The UK will produce 100mph/4000rpm (Approx) 25mph/1000
In 5th The V3 onwards R/RA will produce 80mph/4000rpm (Approx) 19.8mph/1000
In 5th The P1/STi 4door will produce 90mph/4000rpm (Approx) 22.2mph/1000

The V Limited had a taller 5th but the same first four gears as the standard R/RA. This means you had a more severe drop 4th to 5th than before but got the better cruising of approximately 90mph/4000 rpm.

I had my own 5th Changed over on my V4 TypeR for the 0.738 gear from a UK V4 Box. This replicated the V-Limited gearing on my car and gave me better motorway cruising, the one drawback to the car. (Oil starts getting too hot at 4000rpm).

Still the same ballistic close ratio gearing to 4th gear, but a 500rpm bigger drop going into 5th gear, than all the others.

Jonfelstead did the opposite on his V-Limited and retro fitted the higher 5th gear as he wanted an even spread for track days.

SUBTYPER

So Hol are you saying because you changed the gearing on your car you noticed the oil temperature increased.


Ooooops Bob sounds expensive. hope all is well for you and its just a loose nut or something.

No

But I could go 90mph and not 80mph before it started to rise over 95deg
According to Mr Defi!

SUBTYPER

Right got you matey. i am thinking about adding a Oil cooler to my setup. its just finding a kit or a sandwich plate or something to get it sorted. i have also been told i would need it temperature controlled as too cold an oil can cause problems aswell. Any ideas anybody.

bob

Sounds like an engine rebuild needed. Would say Big end as usual.

SUBTYPER

Wow time to change the internals and go for some big power to get up to the 174mph

SCOOBY_TYPE_RA

I find all this information very interesting, but my V-LTD will cruise at 150mph along a straight stretch (1 mile) of road near me. Upon putting my foot down I can reach 160mph and there is more to go before running out of room to allow for safe slowing down, but on every occasion I never notice noises or temperature increases.

SUBTYPER

You wanna take it easy Scooby Ra. last thing you want is the big end going and it always seems to happen on letting off the throttle. Wonder why that is or if its letting off the throttle gradually or just shutting the throttle completely. Has anyone seen the Modified oil pumps would that make a difference

SCOOBY_TYPE_RA

Your advice is much appreciated matey, but I don't often take my baby to those dangerous speeds mainly because I have a big problem with front end downforce. My 22B bumper somehow lifts the car at high speed on uneven surfaces and handling is impaired compared to my previous 99 type ra.

Another observation is that my type r v-ltd feels more stable at high speeds setting the dccd to the third setting. Steering is harder and more responsive.

type R's and Ra's dont do over 140 mph. type ra's do 140 mph max and then allow speedo over reading. type R's do 130 mph then allow speedo over read. my dads 22b over reads by 8mph @ 80 mph!!

ive been at 140 mph and i have had two scoobys reading that there speedo said 150mph and 145 mph! my car does not do 150 mph! (RA)

p1's etc do 155mph so if ur speedos are reading 150mph etc on ur type r's and ra's then they are well over read or you have major different diffs in.

im afraid there was mate.only 300 made. 2 door type RA's sonic blue. ive seen them!

steering is harder and more responsive but actually the diff is just more locked causing the front wheels to work harder and give less drive to the rear.
i found the 22b to handle **** on certain tyres.avon/ expensive tyres and it handled alot better but still with understeer and oversteer(supposidly set up like this,neutral from standard) but i had no confidence in it!

C 8HEP

there is alot of rumors going round like ater a high spepd run when u let off the throttle ur big end mite go. like, if you dont get a knocklink ur gona blow ur engine up. i drove my ra wiv a naf maf and o2 sensor and thrashed it for a month with no problem. all cars are different and no 2 are the same. drive it how you want if its gona happen you wont eva stop it

C 8HEP

do some research mate into type RA's top speed. off the top of my head they do 19mph per 1000rpm in 5th. so check ur speedo when ur next out.at 4000rpm check speedo(about 72mph.then add 3.5/4 x 19) ur car should either rev to 7750 or 8250. either way u should get no more than 150mph. then allow speedo inaccuracy.

p1 = prodrive one

johnfelstead

I have one thing to say to that, complete and utter bollox m8.

This is the graph of RPM v Speed on an STi5 TypeR/RA on standard wheels and tyres.
Rpm:1000 2000 3000 4000 5000 6000 7000 8000
5th:19.53 39.06 58.60 78.13 97.66 117.19 136.72 156.26

At the test day for Ten of the Best II on 13th July 2003, my 100% standard engined STi5 TypeRA Limited (with the normal STi5 TypeRA 5th gear fitted, the Limited has a higher top normally) produced the following top speed run from a standing start at the 1.25 mile marker on 215/40x17 tyres.

C53 John Felstead Subaru Impreza 158.1MPH

They do corners quite well too.

johnfelstead

19.53 MPH/1000 RPM not off the top of my head.

Of course you dont take account of the fact the Tacho under reads on these cars, by as much as 200rpm @ 8000rpm, some are more out than others.

SUBTYPER

God driving them how you like. Now how many people on here is gonna buy a car of c8shep. LOL Surely if you drive the car and look after it whilst driving it will last longer than thrashing it to an inch of its life. I got a type R sti v4 and it gets driven fast sometimes and thankgod it hasnt let go yet but I put that down to sheer good luck and also warming ehr up cooling ehr down and also using the right fuel and mapping aswell as getting thigns sorted when they fail.

SUBTYPER

also must admit c8shep i am impressed you have seen all 300 Type Ra 2 doors. When most of us on ehre havent seen one LOL (Tongue firmly in Cheek)

bob

Had been driving for about an hour at 75-80 New oil cooler fitted new FMIC and new MAF. just been remapped. Oil temp at 75-80 and oil pressure right up on the gauge. A quick blast to flat out oil temp still at 80 good oil pressure. As I liften of not suddenly but enough to slow down the knocking came but not to loud more of a ticking. Saw the oil temp get to 90 then the oil pressure started to drop so out of gear and pulled over. Engine still running and ticking getting louder. Switched of checked under bonet then restarted the engine to hear the end banging quite loudly.
This is my 5th Scoob they have all been modded but this is the first one to let go. Get over it Bob it happens.

sorry, v1-3 not all r/ra's

ive seen 2 3door ra's.

Please ignore my profile name, I now drive a sti 6 type r v-ltd, my post was reference to my previous car :-)

CyprusScooby

P1's started off as Type-R's manufactered by STi and shipped to Prodrive who stripped them of all the good bits and added Prodrive parts.

And according to the model reports in the definitive book - 'Subaru Imprezas by Brian Long', there was definately no such thing as Type-R RA's. STi made the RA 4 door so as it would not compete with the Type-R for sales.The RA was also made to holomgate the 4 door for rallies for Group-N competitors.

johnfelstead

Prodrive didnt strip any STi5 Type R's, they specified a one off build run at the factory to their own spec (which was based around standard STi5 running gear in a 2 door shell), this was built and then shipped to the UK, the cars were then put to final spec by Prodrive, where they added the P1 rear wing top half plus any options such as 18" wheels and Alcon brakes.

Id agree with that,

and also add that the one off build included the special UK spec loom (with rear wash wipe and the switches the same).
There was a rumour that it was just a UK 'wagon' loom, but I dont think they had intermittent wiper control??
