They look great.
Whats with the rebuilds though? Are the engines a bit crap?
From what I gather, the problem was them being designed to run on 100ron, which is not available in the UK, hence them going pop on lower ron fuels. Funny that the Prodrive mapping (which they presumable did carry out) did not account for UK fuel.Whats with the rebuilds though? Are the engines a bit crap?
Perhaps not helped by an alarming number of Impreza owners that I know who use 95ron - I can't imagine a Japanese engine that wants 100ron being too happy with 95.
I would be very interested to hear an in-depth explanation from someone who knows the full story though.

Remaps weren't available back then, hence Prodrive using fuel broquettes to boost octane rating.Perhaps not helped by an alarming number of Impreza owners that I know who use 95ron - I can't imagine a Japanese engine that wants 100ron being too happy with 95.

Oh right, thats a really dumb problem to have. I love the front of these and they look so much better as a 2 door.Perhaps not helped by an alarming number of Impreza owners that I know who use 95ron - I can't imagine a Japanese engine that wants 100ron being too happy with 95.

I ran my DC5 a few times on 95ron and it was spot on, and i know someone else who did it for years with no problems, and thats a JDM engine designed to run on better fuel than we have? Must be cus it's a honda and built better.

Just not seen as sexy anymore are they? The shape is 90's Japtastic

I don't think they ever were seen as 'sexy', more 'brutal'. Or 'like an ordinary car with loads of bits stuck to it'. But then that was the appeal. However, saying that, they only ever got uglier as time went by, especially the whole blob-eye thing... The only car I've felt scared driving was a mapped borrowed Impreza STI.

It's a 60l tank.
Not quite. 55 litre. It costs now about 74 quid from totally empty to fill up. On average, I reckon about 220 miles. But take into account I barely ever drive economically and a lot of that is done in London too.
http://www.p1woc.co.uk/P1/p1spec.htmGlad they upped it to 60 when I had my Impreza. 220 range is pretty shocking.

220? what a luxury.http://www.p1woc.co.uk/P1/p1spec.htmGlad they upped it to 60 when I had my Impreza. 220 range is pretty shocking.
Just bought a P1, was out tonight for a little spirited first drive my local country roads, what a fun car. Will share photos and experiences once I get it out more. Couple of initial experiences, standard brakes are hilariously weak, need to figure out upgrades and new PS4's goes on Friday this week.

They are fantastic and even though 20 years old are still a very quick road car.The brakes should be more than good enough on standard set up. You must have cheap crap brake pads or seized callipers. The WR models had bigger brakes which give excellent feel and stopping power on the road.
Thanks, I'll have the standard calipers and pads checked, happy to try Pagid or similar with Dot5 fluid first. Yes agree its an awesome car. Took Junior out with me this eve and he loved on par with our other toys. Can't wait using it in the Alps. Exhaust is loud though, its defo not OEM, may need to think of a quite solution.
Put some PS4’s on the P1 today, works great and up the grip level to where it’s unreal for a 20 year old car. Also use PS4 on my road wheels for 997.2GT3RS and 991.2GT2RS, great all round tires and handy on wet TD’s.
Now gotta look into brakes, it deserves some proper stoppers. Did a few high speed runs, it pulls nicely and firmly to 150+ dash speed and sounds brutal :-) But the brakes aren’t up for it.
