now i know this may be really hard to explain as none of you are actually here, but i was just wondering about a couple of noises my car has developed(1990 Sil80 CA18DET)(i have had the car two days, so it may be that i'm just being more aware of the noises), anyway

the first noise

when i am coming on boost at around the 50km mark, and it gears up (i drive an auto) it lets out a small sound as it gears up, it sounds sort of like a small amount of boost is being let out, was just wondering if that was normal/not problematic (I have an aftermarket BOV, think it might be boost leak?

the second noise

when the car gets turned on, i noticed a strange almost electric sound, like a fan (no it's not the pod filter or anything), and it gets faster the more i put my foot on the accelerator, however it seems that it only develops after the car gets warm, when i drive it cold it's not there...the noise isnt a belt clipping anything either i don't think as i revved it while a friend looked under the bonnet and nothing, seems to be coming from under the wheel arches?)

the final noise

when idleing there is a sort of ticking noise, that almost sounds as though something on the car is being tapped in with a hammer, at times it gets fastish, then slows down again

Also the center console and footwells seem to get very very hot, i don't know if it's just engine heat or what? anyone got any ideas?

the final two noises i was thinking maybe its a low speed fan or something? i'm not really too sure? just wondering if anyone has had similar noises/ if they are normal or troublesome, or something i should get checked out? i've driven the car all day today, and none of the noises seem to be affecting how the car runs, or anything like that, so i am thinking maybe i'm just being paranoid..

Thanks heaps for your help and i hope it is just me being paranoid:)

      NC MX5

      By The Bogan · Posted

      Purchased a NC MX5 a while ago Basic suspension mods done, BC coils and Whiteline sway bars  New DBA calipers, discs and pads Added some 17 x 8 Konig Decagrams with 215/45 17 PS5's Added some typical NA bolt on's, i.e. full exhaust and intake  Added 0.5ltrs with a MZR2.5 swap, nice bump in torques  Found a detachable hard top which is locked in for a colour match with my local paint shop in Feb 25, this also includes some PDR as it has received a few love taps from parking in the local shops when in the hands of my Minister for War and Finances, me, I park nowhere near other cars and typically park on the street The little thing is awesome, I drive it everywhere, it handles like a dream whether I'm up it or just cruising  But now,  because I'm a idiot, I keep looking at turbo kits....... did I mention I'm a idiot Why is dose so appealing  All of the NA 2.5 glory, well.......until sometime in 2025 anyway....🤪

      How "plug and play" is the Haltech Pro for R33 GTST

      By Murray_Calavera · Posted

      I would not be surprised if you are the only person on earth that has the interest/desire to do that lol.  The Haltech base map is a really good starting point, the car will fire easily and drive very well, even on mild boost levels. To me, following your advice sounds like some sort of ancient Chinese water torcher lol (this is not an insult Josh, never change <3)

      Those car show concepts from the 2000's and 2010's like the Floria and IDx were brilliant and should've gone ahead, at least one of them. But neither Honda nor Nissan are thinking about affordable performance any more, which is truly sad.  Even if Toyota's liquid hydrogen ICE development reaches the point where it's commercially viable and the infrastructure to support it, Honda/Nissan would have to wait until Toyota allow fee access to their patents to offer it with any smaller performance models they released to take advantage of it.

      A sporty manual RWD coupe with a IL4 Honda engine would only be a good thing I assume we won't see anything released for a few years though, unless informal talks and designs have been going on for a few years,  and due to the current, and future, emmisions and safety requirements, I assume anything "sporty" they would do would be at least some hybrid thingie And hopefully anything they are thinking of has nice lines, without lots of plastic and fake bits hanging off it like that horrendous FK8 that looked like it was designed by a 13 year old The other issue of course in the current market is cost, currently the type R is around $70k, a twin is around $50k Meh, I'm old and grumpy and would rather buy a older model car and waste my coin on that than buying anything currently available new
