No, I don't have a sub... yet! Just thought I'd see what could be achieved with these before going all in. Part of me is wondering if these can be sorted to perform well then there's a chance I might not feel the need for a sub as well 🤔 (Well, it's something to experiment with and learn form anyway 🙂)

Or should that be "Shertainly!" 😁

I fitted a Pioneer head unit and did a bit of DIY fabricating etc. Not too sure about the Wood grain on the headunit blanks. They're made of Oak. I might sand them back and fill them so they're just smooth. The phone holder bracket fits into my phone case of Sat-Nav using Google Maps. It's a piece of Ali plate that's screwed ro the side of the headunit into some unsued mounting holes. 'No interior trim was harmed in the making of this' 😆 The USB was because I wanted to have my iPod in the central cubby plugged in with no trailing cables through the cabin. It's an ebay cheapy but does the job. I didn't want to chop up the standard wiring to make the factory one work with the headunit, so it's now redundant 😕 But things are hidden and kinda clean looking so I'm happy 🙂

Certainly! Here you go... 😆😆😆

Was wondering about some enclosures in the voids where the rear speakers are... I'm not expecting anything mind blowing, but think the space could be well utilised for some improved 'sounds' 🙂

It's not a magnetic holder if that's what you mean? https://www.quadlockcase.co.uk/ It's a twist lock/un-lock mounting built into the back of the case. I'll pop my phone out of it and get more photos 🙂 You don't have to have a full case, there's a mount that goes straight onto the back of your phone instead...

Fancy a visit to Oulton Park at some point over the coming months to help build some confidence? I know I could do with it!! 🙂

😆😆😆

Yeah, they were stuck behind me 😳😆

Yeah was great to meet you all! I really enjoyed the driving, even if I was a bit panicky about losing it due to 'wobbly sidewalls'. Hoping my new wheels reduce this somewhat. Thanks for the 'lap' Lauren, it's given me more food-for-thought regarding suspension etc 🙂 I'm looking forward to trying a few track days next year 😀

Having explored the 'potential damage' due to failure in my own mind (and posted my thoughts), I think it's also important to consider the likelihood of failure and adopt a pragmatic/realistic stance on it. Regarding modifications I understand Toyota's attitude is that warranty etc remains valid on any parts not directly affected by the modifications. To my mind valve springs are unlikely to have had any extra stresses effecting them due to forced induction. If anything it would be the running surfaces of the top of the valve stem/follower/cam lobe due to higher cylinder pressures during initial opening... maybe... 🤔 High engine rpm is more likely to influence stress/strain on the springs due to faster load cycling and the potential for valve bounce. I understand that fitting stronger valve springs/double valve springs is a way to reduce/eliminate valve bounce at high rpm, but this is more the preserve of highly strung race engines (10k rpm or higher?) as far as I'm aware?! Realistically I think it's pointless worrying too much about the situation until the bulletins/letters are released by Toyota/Subaru. Yes the likelihood of failure is a concern, but if you're personally that worried don't thrash you car for the next couple of months and see what the manufacturers have to say...

In my limited understanding and own thoughts regarding this, a failure could vary from little impact to quite catasrophic! (I've had some training in early failure detection and oil debris monitoring for Gas Turbine lubrication systems, but only training). Firstly I imagine there have been some impurities in the metal, or problems with heat treatment, which would instigate a crack and eventual failure. (Ever seen a broken suspension spring? You can normally see where the failure originated when you look at the jagged surfaces of the failure point). Depending on where the crack/failure is in the spring may mean it just stops holding the valve closed meaning no compression and no push on the piston. This could also lead to valve-piston collision (if the engine is an interference type). If it's just a small part of the spring (half a coil maybe) then this could break free and float around, get jammed in othe moving parts causing significant damage (wedged in other vale springs and mashed, getting jammed under the cam lobes, interfering with variable valve timing/lift parts and jamming those, floating round in the oil system and jamming other moving components). It's really not a good situation however I think about it 😵 If Toyota/Subaru are going to replace them FOC then I say don't hesitate!! Sorry to be alarmist, but I feel it's not something I'd be putting off! I'd say it's more likely to occur with higher mileage due to the strain (stress over time) of repeated compression-extension cycles. It quite a complex thing to analyse/predict, which is why I think the recall covers so many vehicles...

I hope the unforeseen events aren't of an unfortunate nature! 😕

It's worth checking though... If May's the cut-off for build then your car might still be affected. If you think about shipping times, and UK spec additions/modifications carried out at the docks before delivery to dealerships 🤔

Might be batch number controlled... A few suspect items in the batch and you recall/write off the whole batch as suspect 😬

Cool! Will be interesting to see if the parts compliment each other 🙂

Oh ok! Yeah I've heard of this being used for cleaning deposits off of Gas Turbine engine compressor sections whilst they're running!! Although they tend to use de-ionised water these days... First I've heard of it for piston engines, but every day's a school day 🙂

Yeah, Mach 3? Venus? Wilkinson Sword? 😆😆😆 Or is it a toffee hammer?

I broke my wrist back in August and am finally back to 'health' today. Managed to get copies of my x-rays at the checkup today too. Anyone else got any metalwork or scars? 😀

'Walnut blast'?!! What's that then?

That looks really cool! 😀

Thanks for all the replies and explanations. I intend to follow the well trodden NA path... (for now). These just seemed to be an oddity in my understanding of how changes in the inlet can manipulate performance. That said the other NA 'bolt on' inlet tract mods I know of get their gains because the manufacturer deliberately de-tuned the engines before putting them on sale.

Welcome aboard 🙂 Reckon you'll collect early enough to make it to the Evo Triangle as Lauren suggested? 🙂
