Just bought this ....

[John Laverick]

1998 Subaru Impreza WRX STi Type R

Loving it so far [although I've got to stick below 3.5k revs to run the engine in]

[mjrc]

looks good! rebuild engine is it?
dont know about the tinted windows in the back... either all windows, or my favorite, no tints at all

[Col 666]

Very nice, just be careful what fuel you put in it! Unless its been remapped for UK fuel always use super and if driving it hard stick some octane booster in there too.
Here's my old Type R-

My big end's went after 6 weeks resulting a very costly rebuild Superb car though, a bit of a handful in the wet as they are very tail happy, completely different to all the other Impreza's I've owned...enjoy!

[Stedman]

Very very nice. Is that an NSX in the corner aswell?

[John D.]

Both Scoobs are How do these compare to a P1? Bit less supple for the UK roads?

That is an NSX lurking in the other pic I'm sure.

[shalmaneser]

I LOVE the look of these 2 door (3 door?) Scoobys. Both looks awesome.

[John Laverick]

Thanks for the comments ... I personally don't like the tinted rear windows either but I believe they come from the factory like this and the tints can't be removed?

Yep .... it's just had a bottom end rebuild due to No. 4 Big end failure 2 weeks after entering the country!

I'm aware of the fuelling issues and plan to get it mapped on UK fuel a.s.a.p.

Yes it is an NSX lurking [the previous owners housemates car]

Lovely looking Type-R not seen one in grey before,are you going to remove the WRX sticker from the boot lid? For me it just looks tacky!

Yes ... and the ones from the side also!!

Octane boosters have no effect whatsoever.

Good man

If you dont mind me asking how many miles has it got, and how much did you pay?

80k and just under £5k ... the mileage was a bit higher than I'd hoped but my theory is the re-built engine should give some confidence!

Good price, these are really coming down!

Where do you get this pearl of wisdom from??
I have owned 5 Impreza turbo's over the past 10 years and have a far bit of technical knowledge of the fuelling that they need.
In japan they have 100 octane pump fuel, as I assume you know we only get 97-99 octane. The import scoobs dont like running on normal unleaded as it causes pinking/detonation and can destroy engines pretty quickly as I found out!
When using octane booster it brings the octane rating up about 2 points to match the japanese fuel.
I had a knocklink sensor fitted in the type r and when running normal unleaded it used to flash up warning me of pinking under hard use but with the octane booster no warning lights displayed no matter how hard I was pushing it.
This was using proper Millers Oils Octane booster none of the rubbish that halfords churn out.

What?

Octane boosters, give the fuel a higher octane rating, reducing the chance of DET. In what way dont they work?

I think I already know the answer to my question but I'll ask it anyway for piece of mind. I driving my car VERY softly until I get it mapped [under 4k and no full throttle] ... assuming I stick to this its not really possible to get detonation damage is it? My understanding is detonation usually occurs under sustained full load at high revs?

I was told a knowledgeable person who works in engine development that these octane boosters you see in Halfrauds and other motor factors don't have any effect, at all.

Although Col says that he has had success with Millers, so it seems there are some that work.

Your right, driving like Miss Daisy will be fine although its a nightmare when its so short geared eh?! Just keep it off boost and short shift unil you get it mapped/run in.
Detonation usually only shows up when your really ragging it.

Yes it is a nightmare … it’s restricting my top speed to about 60 / 65mph!!
