OK so I have picked up my teddy after throwing it out of the pram, and the Meglio is now up and running. Did 40 miles testing over the weekend and just drove it 30 miles to work.
The header tank, I went to the local scrappy and bought the smallest one I could find but that didnt work so I stuck with the Sandero one. I cut the press-fit washer off the rotation mount bolt and only fitted the powerflex washer (bigger) - as the bolt was double washered basically. That got me a couple of mm more space, I also trimmed the plastic wing bit on the car and angled the header tank down. It's a bit of a nasty job and I will come back to this and make a proper bracket instead of the big zip tie. It is retained at the back on a bolt through the turret.


Also the interim air filter (pending replacement with a proper Megane induction setup) is basically duct taped to the inlet pipe

so thats also on the list of things to change up.
Reverse still doesnt quite engage right so I need to pull the battery tray out and trim it properly to 100% clear the linkage.
Other than those items, its running and driving lovely. The car is totally transformed. The conversion has fixed *all* of my gripes with the original setup and i'm also getting better MPG. Like 30% better. Cruise works, trip computer works, everything works. I really don't know why Renault didnt fit this engine in the first place, it's fantastic for the car. After 30 miles I stuck my boot down and it's REALLY impressive for standard trim, it's a proper flying machine. Absolutely chuffed to bits, it's exactly what I hoped it would be!
Budget wise to date, I have spent:
£1000 on the conversion package
£90 on the decat downpipe
£15 on the header tank
£80 in fuel viewing and collecting the conversion package
£30-£40 on engine oil, box oil,
oil filter. Coolant and brake fluid I had 'in stock'
I bought a Meglio shifter and Meglio engine loom separate but didnt use either in the end so not counting those
£15
eBay cone filter
£70 on having my 197 immobiliser data copied to the Meg ECU, at EFI parts but I didnt pay for that my mate did after I lent him the 197 for a couple of weeks last month.
£5 on a header tank that didnt fit
£5 on a box of rubber gloves
£10 on coolant as I was out of stock
Running spend total - £1260
Sold the box for £100 (Cheap as it had the 3rd gear crunch on downshift)
Sold the engine for £400 (Good money as it was great nick and only 75k miles)
Running total with sold offset - £760
Away it goes
£760 with a bunch of ancillary bits like driveshafts and shifter etc still to put up for sale - absolute bargain! A significant amount less than the belt service, remap and box rebuild the car needed with a significant upgrade to boot.
