Looked a fair bit more than whatever brochure power limit the are quoting nowadays.
Still. Anything under an 8 is pretty good. Considering visibility was not the best, and track conditions appeared to be slightly damp.

Ok cool, does this 8 bit chip Fit in to the early ecus? without soldering? Have Been told on the 89 models Theres a slot You put it in and all you need to do is cut a resister? Is this true? Cheers
Yes, or you can run switch in between the resistor ends. So you can toggle from the chip to stock.

Most are based on the same or very similar maps and re branded.
Two different types; An 8 bit chip or 16 bit eprom board, which is two 8 bit chips mated.
Your BF5 will be an 8 bit, at least from factory, so you will be looking for one of those.
If you want to run a 16 bit board then you will need a Series 2 computer.
I run a VOS 16 bit eprom. cost me $350 from Australia, but has had extensive R&D including Dyno time, Specific for Series 2 RS and GT Liberty/Legacy.
To get the most benefit of the chip you will require basic breathing modifications which you have already done.
Along with this you will have speed cut removal and a revised boost cut limit. I can't comment on boost algorithms or ignition and fuel curves but these will be altered as well.
You could expect about a 20-30kw@wheels increase, and have the mid range filled out dramatically compared to stock.

What impressed me about that car from memory was it was running a OE 5MT.

Thread cleaned.
Back on topic.

ok.
I'll buy "genuine" subaru stuff if other brand stuff is not good enough quality, but I won't pay their markup
for EXACTLY the same product if I don't have to. And their markups are obscene, especially when
there's about 5 different markups on anything by the time we get it.
Agreed.
$1000 for a genuine STI forged piston, which are probably outsourced to one of the many piston manufacturers offering similar but four of.

Are you just a snob or a subaru whore?
There are plenty of reputable companies on the planet not called subaru :
Diesel and turbo would give a warranty BTW.
I think you misunderstood, I'm coming at it from both of your points of view.
-
So even when its most likely off the same assembly line, and through the same distributors, probably came in on the same shipment its not geniune unless a subaru registered mechanic/dealer has added an obscene markup?
I suppose so. They won't offer any sort of warranty on a Turbo that is absolutely mechanically the same that you brought from Kebabhairdriers.com
-
Through Subaru it would be "Genuine"
Through aftermarket then not.
-
These are road cars.
And so should be judged as such.

Not really, more tomato, potato. Totally different.
i.e. my turbo has a rather high boost threshold (~5500 rpm), but its not that laggy at all. If the engine is above the threshold and I am on and off the throttle, the boost response is instant enough for all intents and purposes.
What gearbox are you running?
With such a high threshold you would benefit from gearing it closer, but i suppose you wouldn't want to lose out on Top speed.

Hes running Link G4 boost control so thats no issue.
If you pop in to the shop we can show you a few sheets from people such as vivs car etc as a comparision.
I know vivs car was limited by ingnition break down. We did Jos with an old possum link and got 220kw or so outa his TD05 on about 16psi from memory.
For a street car I would go VF over TD just for the responce. Though a TD turbo seems to make more power on less boost.
I can supply you a front mount kit thats pretty resonably priced if your interested.
440s Will be maxed around 220-230kw
The part that was nasty about your exhuast from memory was how it has the small section just at the bottom of the dump pipe, Though you do want atleast 2.5" from the turbo back.
We can do Exhuasts as well, either custom Fabricate or supply one.
Just remember as soon as you change anything it can throw the tune out, particually injectors, turbo and a free flowing exhuast.
If you are un-sure about anything feel free to give us a call as were happy to help.
Also can you PM me your number plate and your Email and I will send you your Dyno Sheet.
Joe's was a worked TD05 "big" 16g.

Anything from Subaru these days and I yawn.
And when I see Cosworth, I just shake my head. Most of there kit is re badged and outsourced. And their long blocks are hideously over priced.
Far from the rep that they had in the days when cars were analog and had hairy chests.

Redline advertises those as I beam, but in the picture they are H beam.
H beam connecting rods are said to be suited to high boost or forced induction setups.
I beam connecting rods cost more to produce as they require special machining.

Thread cleaned.
Remain on Topic.

Ever wise? I dunno about that lol!
I know of one that is in development at the moment, and that would be Jason Liefting's race car. He would be one of the best (local) persons to speak to about it if you were planning on a dry sump for a Subaru.
Do you know how that is going? I know he's been busy; going over to Australia.
I believe he was going to design a different exhaust manifold, to utilize the dry sump setup.

Interestingly (to me) the Cams of my new RS RA heads featured slightly higher lift than my original cams.
Could be a Series 1 to Series 2 difference.
-
They will be solid lifter heads if they are V5.
-
I wasn't speaking of STI spec.
-
I should clarify, I was meaning V3-4 STI cams into V3-4 WRX heads. And same for V5-V6. But I'm not an expert.
I've not seen earlier versions to later etc.
98 and earlier - V3 V4 STI cams.
99/2000 - V5 V6 STI cams.
Although even standard MY98 heads will flow well.

Agreed, But not for setting a benchmark on the Nordschleife.
