We will get to ECU’s etc shortly… but interested in your view on the EMU as it may be in my future 
So car was then ok for a while… I did some track days and temps seemed ok too, I could keep up with most Exige S’s, so all was good - then I got this…
Engine light etc… so back to EA again who identified a split hose that was causing the error - took quite a time to find it, think a smoke test finally weeded it out. Whilst they had the car, I also had an "Essex Autosport’ Baffled sump fitted which is till on the car now and has actually done a good job.
With the engine light issue solved, the car felt better than it had done for a time… so maybe the air leak was there for a while to a lesser extent. Ran the car for a couple of years in that state, until stories of katana cars having issues with higher mileage started to emerge - even though I hadn’t had any heat issues, inlet temps were a concern, and as I was doing less than 5K miles a year on average, my katana mileage was still relatively low… I started to look at options…
Inlet temps are always going to be a challenge on non inter cooled cars, but with minimal boost it should last ok, this is interesting reading, keep it going
Yes… agreed on inlet temps… mine were ok when measured… but I didn’t want to risk the engine… so decided for another option…
so, with a European road trip of 3K odd miles planned in summer 2014, my AC not working, and very rusty towing eye I started to have discussions with Hangar 111 on their 280s kit with a few options… more on that later or tomorrow…
I had the EMU Black installed on the Monday that they started to enforce the lockdown - and since then have had the whole engine in pieces to find the lift bolts that had made a bid for freedom to the bottom of my engine… it has all been a mess, but suffice to say I’ve not done many miles yet, lol 
Oh no ! what happened ?
Jeez, I feel like I need to make a blow-by-blow post like yours to give the full story, but the long and short of it is that a Lotus main dealer (not saying which on here) changed my cams for me (and I gave him new lift bolts to swap at the same time) and afterwards lift was intermittent. Got the EMU Black to sort things out - didn’t work. Got a shiny new valve cover because… well, because ‘shiny’. Went to fit it and found I had no lift bolts at all and both rocker shafts out of alignment! Ordered new lift bolts and went to fit them… and then spotted one of the old lift bolts on its side, next to the exhaust valves… then wondered where the other one was! 
So I went exploring - and eventually found the other one in the bottom corner of the engine, stuck between the oil pump and the timing chain cover… My hands are destroyed, but I feel good that I’ve managed to find them and put the whole engine back together again before something got damaged - and I’ve renewed all the 16 year old gaskets along the way! (and fitted a Moroso baffled sump at the same time, because I had to take the sump off to inspect in there). Runs like a dream now! 
Phew… good save then… but bad on that dealer - that’s a big miss !
Happy to hear your full story
It amazes me that those bolts can ‘fall out’ anyway, they must have literally been hand turned in a couple of times and that’s it - I’m pretty sure the torque spec for them is tiny. In fact it makes you wonder if an apprentice slipped, dropped the bolts into the engine and just panicked without telling anybody and put the lid back on!!
Although I was in discussion on the engine, I had this pic taken at a track day…
That told me that there were mounting priorities for the car - plus it also needed new discs as the OEM ones were looking a bit worse for wear…
You’re not alone in those thoughts 
Toyota manual says 8NM and no thread lock… I’ve read people advising thread lock as they can work their way out, but to have both of them fall out within a hundred miles (I took it back to the dealer 100 miles after they did it, before I had tried to rev it, just so they could flush the oil to get rid of the assembly lube and check everything was as expected before I gave it some revs, so have no idea if it ever worked before that 100 miles had passed) - well, it just all seems a bit unlikely - but you never know I suppose… 
Anyway, it’s all back together (complete with a small amount of thread lock!) and ready for the next track day - whenever that is!?!
Some decisions were then made - I would get the suspension done and uprated discs and pads at the same time… the engine would follow later. So booked in to Hoffmans for ‘Randy’ spec nitrons, with Eibach springs of course and a full geo and corner weights, EP uprated grooved discs and Pagids. Car stayed longer than expected as the castor was identified as being uneven side to side which was resolved. When I picked the car up, I remember thinking how cool it looked with its new stance. The ride was way better then the OEM setup… I don’t have a pic from that time… but I do have this one whist the car still had its track focused setup…
The rake was only 10mm but looked more… front ride height 115, back 125 - Car weighed in at 908kg with a full tank.
Understeer was gone ! I remember barrelling into ‘Hamilton’ on the Snetterton 300 circuit and felt the rear go light way earlier then before… but it did teach me to drive it a bit differently as I had of course been driving around the previous understeer that had now been eradicated. Brakes of course were way better too…
Great picture!
Fascinating read Thanks.
Great write up and pics
Thanks guys… more to come
Its late 2013 now and still talking to Hangar 111 on options… friend was taking his car to Surrey rolling road near the longcross test track, so I decided to take mine and see what that rolling road would say… turned out it was 211hp give or take, so well down from what I had expected… even with rolling road differences. That and more katana issues being documented, decision was made to get shot of the katana and the car was booked in to Hangar 111 for early 2014…
So early 2014 - car goes into H111 for the work… While clam is off to fit charge cooler radiator, I have a new pro-alloy rad fitted, new AC condenser fitted as that was the issue with the AC. Front towing eye replaced. Obviously I have new injectors, fuel pump, charge cooler, brand new supercharger and associated bits. H111 inspects engine… no bad wear to be seen - Mileage is 38K at this point…They cleaned the valve train check cams etc etc… all seem good. They do find fur in the throttle body from the piper cross - so that’s cleaned and a coolant hose replacement which had not been done by B&C was done in line with a service bulletin. So 280s kit fitted and ready for road testing… something isn’t right… car doesn’t run smoothly at all…
Pic below shows my charge cooler rad
