Ok so I have been reading up a little on thermal coatings for engines and I really was only aware of certain things being coated eg manifolds in HPC etc. But some really practical things I am seeing is coatings of internals for improved performance. I have had a look at a few sites regarding coating pistons,Heads,valves even valve springs, Supposedly they trap far more heat into the combustion process and also have a higher detonation threshold due to reduced hot spots. I must admit it all looks great..Just wondering if anybody on here had had any experiences with it they wish to discuss

have had pistons ceramic coated before and with moly coated skirts. and bought HKS step 3 pistons before which have a ceramic crown, moly skirt and some kind of titanium coating on the ring lands. I don't really know what if any difference it made but the theory seems sound.

i have never done this myself, but the logical reason for doing this would be to reduce heat escaping through the head and pistons to reduce temperature.

edit: didn't read the full post, i would also like to hear from anyone who has done this.

      Who has a Infiniti Q60, Q50 (V37)?

      Yep, it was only an option on the Q50 Hybrid.  Same in Japan as far as I know. And doesn't use a centre diff like the Suby's do, so not the same as the WRX.  But it also isn't a reactive AWD like other Nissan AWD vehicles are, eg. Murano/Xtrail/etc.

      You should have got a Maine Coone then. Only thing is they're big. But so cool, and just like a dog. Or, just get yourself a high performance dog. That'll teach you for wanting Parkour indoors 😛

      Are you thinking of Bens R32? I don't remember if his went through the bonnet itself, but it went through the chassis rail. Brad (RISKIN) bought it, and turned it into a track car. It's funny how anti people are of Jim Berry now. I remember when I pulled mine out (during an engine change) and inspected it and found it cracking badly. At that point in time so many people were even on SAU, were so pro Jim Berry, and that was after Bens GTR exploded his quite publically.

      That's one of the reasons I got that breed, they look weird, the other reasons are they small, they are very vocal, and run around like they are on crack, I didn't want a breed that just sits around, these two are like kids on red cordial  My daughter has one, and it's a laugh riot, constantly doing Parkour around the house, sits on her shoulder, plays catch, and constantly runs around the house taking turns chasing the dog around, her Bermese though, just lays around with constant bitch face, and just looks on in utter disgust at the cat and dog playing together

      I'm getting PTSD flashbacks seeing that name again.  With my turbo swift, I got 1,500km of street use on a Jim Berry clutch before it exploded and took out my input shaft with it.
