Very nice You forgot the photo with the turbos in view though..

Took me several hours of waiting to get that shot. Animal photography

This must be somewhere around 15?...

Ahhh. I know that one. I've posted it up on oldschool before because a friend of mine in chch owned it for some time. Great combination!

Dylans mate pops his head back out of the engine bay and says "looks like you just blew a seal" Dylan wipes mouth and says "nah, I just had an ice cream"

What was the imps setup in that race? it did pretty well!

Such a fun game stripping down a spares car and collecting all those bits. One of them might just get used in the future and all those times stepping over them, kicking them and moving them will be forgiven when you get to utter the following words... "I knew this would come in handy one day!"

"I had to grab his trousers and forcibly lift his leg up, and he immediately got a totally inappropriate erection" Oh yes. Such mirth. You didn't know which gearstick to grab after that. Oh how we chortled when I suggested you scribble the numbers 1 to 5 on my knob with a vivid marker.

Yeah I've tried that too. Still there. @chris r has messaged me just before and said to recheck my idle bleed screw. He had exactly the same sound. Turns out I'm not the only one suffering from whistling Honda throttle bodies. Loads of threads out there around the world with the same issue. When I rest my ear against the top of the plenum lid the sound is amplified and does sound like it's coming from the tb. I'm going to have another look at this tomorrow.

I had considered that but its really hard to hold it in a place where the noise shows up unless driving it.

No such issues with my airflow optimised Mandalorians. They have helmets on. Very aero helmets at that..

I was starting to think its something like that too. If it was a simple vacuum leak I reckon it would do the sound at idle with the throttle shut when its at max vac on the engine side. I also removed the iacv and blanked it off to make sure it wasn't that creating a sound so I know that's not at fault. There is a thick card gasket I had made for between the TB and the mounting flange. Just a square, one big hole for tb bore and the four holes for the mounting bolts. I wonder if its flapping/whistling where it sits over one of the various bleed ports?

After my last long wall of text I'll try to keep my updates more frequent and smaller. The throttle was a bit sticky and made gentle opening awkward. Parked the imp outside in the sunshine.. Removed the access cover.. Adjusted the throttle stop screw about a half turn in. Just enough to stop the throttle plate from sticking. You can see it here with a mirror... Then wound the idle bleed screw in and touched up the tune around the idle area on laptop from the comfort of the rear seat.. It's now much better in action and way easier to drive off. Although I'm happily getting the last bit of wear out of the old tyres and they always feel super stable and grippy when getting low, like a semi slick, they most likely wont pass another wof test. They have always worn on the outside which I found odd considering the amount of negative camber. I have always swapped them back to front regularly but they still wore as such. I thought I best check the toe angle. I'd previously done it with string. Not the best way and quite a faff. So I made these measuring jigs up.. They bolt in place like so... Making it much easier to check the toe angle very accurately.. Turns out I had set it pretty close. It was a little bit too much toe in so I adjusted it out to suit the specs and I'm happy enough now to get some new tyres soon. Another small job I should have done years ago was to make some form of face level ventilation. My imp gets quite fumy if I open a window. I had asked on the facebook Imp owners group and it looks like its an imp thing that most folks cars suffer with. You have to hermetically seal the back end up of every little hole and gap to try avoid it but its tricky and my imp is possibly worse now with the centre exit exhaust outlets. I just had to do something about it. I got this lot.. Cut a hole here in the plastic ventilation pipe the comes from the fan/pickup and heads to the heaterbox.. Pushed some alloy tube wrapped in gator tape into hole... and popped the flexi alloy ducting in place... I'll look into teeing the ducting off and run some to the passenger side as well. I need some neat little eyeball vents which I'll then fit into my new dash layout I have planned. But even this alone is a game changer. Even just driving up our driveway I could feel the flow of fresh air. Sooooooooooooooo much better. Wish I did this years ago! Final bit for this blurb. From the very first time I started the engine on the bench there has been a little random whistle. It didn't bother me at the time because I was just so happy the engine ran tbh. But now its annoying me. Its not there at idle. Only when you open the throttle a bit from idle will you get a little squeak or if driving and it goes under a moderate load it can be quite loud. Off with the access hatch again and with Hannah driving the car I tried to pin point where it was coming from... Once home I continued the search, checked all the bolts, used bluetack to seal any suspicious gaps but no luck. I've not nailed the spot but I think its around the plenum chamber or possibly something funny in the throttle body. I got annoyed, gave up and we just went for another hoon to the beach for walk.

This is the stuff we've been using the last few years. Is actually nicer in use than Por15 but it still wont stick to shiny new steel unless, as pussycat whisperer above stated, you use some sort of acid etch first. https://kbs-coatings.co.nz/products/rustseal?variant=30214165987381 (really cheap through supercheap on trade account btw) I just use it on rust and for new steel I use Resene industrial 440 epoxy primer.

There's some aussie made alternatives to por 15 that I have found to be better and a bit cheaper. Bilt hamber stuff is great. Wins a lot of comparison tests etc. Unfortunately no one is importing it into NZ. When I moved back home from the UK we brought over a whole box of cans of bilt hamber cavity wax. (dyna S50?) Best stuff I have used yet.
