I hear what you're saying Logan. Having spent time/money taking the handling, brakes, and engine ancillaries to a good level I'm tempted to do something similar to Ian (DaOne). That'd be a forged 2.1 stroker from EngineTuner (which seems like the keenest deal around and one I'd like to know more about), a Harvey or AFP 20g and a fuel pressure reg on top of what I have already. Big thanks to Ian for letting me drive his car last night; was amazed at how tractable and well mannered it was low-down, and of course impressed with its top-end.
Don't think I want the alternative of installing a s/h block and flogging it, at this point in time. Or the soul-destroying faff of replacing the trick bits.
What I want basically is a good road car that can do a few trackdays and the Nurburgring next year. I had the road and the 'ring in mind when swapping from coilovers to the Ohlins + mild-uprated springs. Have found my best so far combination of struts/bars/geometry in an Impreza - the handling at Mallory was spot on, as were the AP brakes. I still like the classic Impreza. So long as I can properly understand the failure and avoid it next time I'd like to take it one step further, a fairly logical step. Am not interested in chasing endless power hikes (seriously; the bikes I ride will always be faster) but I'm thinking high 300's bhp is a sensible-ish place to take it. Transmission is the one thing that may remain a concern (less so if I don't sprint it) and if that goes it would mean spending 2 grand on a 6-speed.
Logan - how fast was the spin that was implicated in your big-end failure? (and surely the roll could equally have starved the pickup?) The sages on 22b are pointing at the the oil temp, oil age and 100+mph right-hander Gerrards in my case; noone's commented on the spin yet.
Big end failure, det or oil surge? (long post)
2.5L bottom end and 20g will transform your car for not too much (ask anyone who sat in my car a couple of years ago). Std. internals will be good for whatever you can get from the turbo, just shy of 400BHP with possibly 380ft/lbs on Tesco 99. 10% methanol could see a few more 10's of both. Sti4 heads are good. I'm surprised you don't have an adjustable fuel reg.
Sort parallel fuel rails and you must get a fuel swirl pot sorted. The difference a decent fuel supply makes is enormous to reduce worrying about starvation and subsequent det.
Decent Exedy clutch (see APT) and the box should be OK for 350+ certainly with no drag starts.

Keep the classic Andy, a well sorted one looks fantastic and has the mechanical integrity to back the looks up all day long.
I don't know enough about your circumstances on the day to know for sure (who does?) but I would lean towards oil starvation/surge as the most likely factor. Age of oil and temps would have a bearing (if you'll excuse the pun) but surely this is no more complicated than that?

I slid broad sideways at circa 80-90mph for a few seconds, this is what did the engine the second time.
The first one (standard engine) was overheating the oil on the Nurburgring, funnily enough catching a 911!!!! Oh dear!
As for thinking about Enginetuner, I would consider what if you have issues etc, it's a hell of a long way away to take the car back there!! Maybe something to consider??!!?
Good luck with it Andy.
Gerry - if 2.5 blocks are still available at reasonable money then it's certainly an option, but I would think its torque will stress the gearbox more than a 2.0/2.1. Also a bit concerned about the all-round practicality aspect as a road car - the erratic oil consumption of some 2.5 builds, and going further along the continuum of bigger power, more fuel and mechanical stress. Yours was a track car primarily, after all.
Logan - did you have baffled sump when it slid, and do you know the oil temp when the first one let go? Damn 911s, eh!! Enginetuner is indeed a long way; will talk to Gary at APT, Bob at BGV and others. Already talked to Zen, whilst at Mallory in fact, but they're chocka with work as usual and Paul looked dog-tired the last time I collected my car from him! (presume from late nights on the racecar after long days on customer's cars)

Andy, When my car went 2.5L/20g in 2004/5 it was primarily a road car that did the odd sprint and track day. It was my daily driver as the other car was a Chrysler Grand Voyager which was too juicey, big and boring. It was another 3-4 years before I flogged the Chrysler and stripped out the Subaru.
2.5L on the road with 375 is great. Oil consumption was a pain but it was being lost externally rather than burnt or blown out. 2.5 has always been a cheap quick power hyke and you have the supporting mods anyway or very nearly.
300+ BHP will consume fuel at a similar rate regardless of engine capacity.

Nope, as I was told at the time running on list 1a tyres it should be fine....bugger!Andy916 wrote:

No idea on oil temp, as the car was completely standard bar a catback exhaust at that time....best time I had with the car when it was like that.
Sounds a bit like my first scoob, a '95 WRX, with just a Magnex decat and that's how the engine stayed, more or less. Did a Bruntingthorpe day soon after getting it, loved it. Met Gerry that day and bought his STi backbox to quieten it down a bit. Over 2 years I did suspension and brakes, lots of trackdays, even ran slicks briefly and the oil pressure was fine round Coram at Snett for example. Ran it between 100k and 130k miles and was still going ok when I sold it.

By comparison the current one has been endless work and not many miles...
Gerry, you're tempting me on 2.5's. Now, a fresh build is the thing to do and I'd normally be REALLY wary of s/h engines, but this one may be worth a look:
http://bbs.scoobynet.com/private-sale-c ... aking.html (breaking as he's failed to sell it intact: http://www.pistonheads.com/sales/1198144.htm). Built by Howard at Autosportif, apparently. Deal would be EJ257, AFP 20G, MAF and copy of map which would then need to be tweaked. Claims to have done road miles only and seems genuine looking back through his history on SN.
Andy
Apparently 'sold' means that someone on SN has said they'll have it (not quite the same as sold, as I've found out multiple times, on SN). It's all still together, can be heard running (not sure if car is driveable though) and he'd include the 20G as part of a package. A test run with boost would be ideal, I presume, rather than just hearing it run statically. Guy is in Crawley.
