So where are we at, Took the twingo to the Cliosport Festival. The drive up was stupid with accidents and diversions along the way and took about 4.5 hours. Drove up with @Jezer101 and met up with @Ricardo for a night in the hotel. Got up the next day and met up with the rest of you reprobates The car performed ok throughout the day despite the heat so was kept in low power mode. Intake temps stayed only a few above ambient but the coolant wasn't as happy. It would regularly rise to 100-105 and require a cool down. By the end of the day you struggled to get a good 2 laps in before having to cool down. Upgrades are on the cards to address that, I also have a turbo that may be starting to weep a little when up to temperature. First job when home on the Sunday was to give it a once over, no oil in the boost pipework or catch tank. Nothing to note in the bores and compression still the same as it was. Spark plugs looked good too. Though no oil has been spotted in the downpipe I'm still leaning towards it being the culprit of the smoke . Only real casualty was the loss of a turbo to downpipe bolt. Anyway @Brigsy has donated me an ali rad so that can go in soon and hopefully help with the cooling and ill try and find myself an undertray which I hope will keep air going through the rad rather than under it.

It's been a few weeks since blyton now and thanks to @Brigsy its had a pmt ali rad upgrade and mocal thermostatic takeoff and setrab external oil cooler. Temps now stay pretty solid in the 80s even with 28/30 degree ambient. I've done some constant silly pulls and can get it to the low 90s where it still stays solid until I drive sensibly and drop them down a little again. I'd defo say that's a win so cheers Jon It's defo getting tight in there now. Next news is the turbo is on its way out, it was a second hand unit when I fitted it and as seen at Blyton it's starting to pass a little oil when warm. Still undecided on which route to go yet as currently the car is fantastic, I worry that a bigger turbo will make it useless and break more things. Will have a think on that. I did a little Q&A video so popping that up and a turbo noises vid too. Give us a like and subscribe, it'll be much appreciated
So a small update, the car is currently off the road. Turbo was whipped off and sent to TurboDynamics for a refresh. I also included a spare stock turbo just in case they needed any spare parts to work on mine. The report came back and it wasn't great tbh. There was some forward an back play in the turbo which has written off the comp and turbine wheels, bearing housing and backplates. The oil feed in the thrust bearing was partially blocked which likely caused the issues to start and probably came from me running the Turbo after the rebuild. Oversight on my part, not sure why I didn't fit the old turbo or an inline filter like we would on the old Renault 5 GT turbos. For some reason it was fitted with a TD04L turbine over a TD04 item, even though the wheel is a tiny bit larger it has an extra blade in it and would of probably caused my top end restriction and lower peak figures. TD couldn't think why it would of been used as it adds restriction rather than reducing it. Out of all of it the only parts being salvaged for use on the new unit are the bearing housing from my old stock turbo and the machined compressor housing (which wasn't done to a high standard either so is also getting reworked) So all in all my still boosting fine turbo that had a bit of play and oil loss is a write off lol On the positive side, (after a little bum and wallet raping, though still loads cheaper than an off the shelf hybrid turbo) ill have a newly assembled 19T Hybrid with nearly everything new, built up with cut back turbine blades and upgraded thrust bearings. TD04 11 blade TD04L 12 Blade Thanks for reading
Adey, I need to say, never thought to remove a turbo leaving the turbine housing in the manifold!! I imagine, depend of the engine, would be easier or not. But good idea anyway I like those houses in UK, with a place to work in your machine, a little garage in the house.
