I've been using an air fed full face mask, in theory I reckon it's a good solution as long as the air compressor is somewhere it isn't going to suck in the fumes. Nothing in your eyes and even without a perfect seal it'll be a constant positive pressure so nothing bad should get in. I got mine from Trademe years ago but it looks like this aliexpress one: https://www.aliexpress.com/item/1005009111590394.html?spm=a2g0o.productlist.main.14.1c2451ddUQCma8&algo_pvid=6ceaa51b-9928-40f0-b692-a2a0430484b8&algo_exp_id=6ceaa51b-9928-40f0-b692-a2a0430484b8-13&pdp_ext_f={"order"%3A"37"%2C"spu_best_type"%3A"price"%2C"eval"%3A"1"%2C"fromPage"%3A"search"}&pdp_npi=6%40dis!NZD!270.93!124.63!!!1064.15!489.51!%402101ef5e17737153286372035e2d33!12000047955162547!sea!NZ!774595986!X!1!0!n_tag%3A-29919%3Bd%3A46ab3cd8%3Bm03_new_user%3A-29895&curPageLogUid=YtHvr7LWr5nX&utparam-url=scene%3Asearch|query_from%3A|x_object_id%3A1005009111590394|_p_origin_prod%3A

Finished one half with the redesign, looks very similar but started from the beginning and changed: Much thicker flange. Removed injector cutouts. Removed cutouts in flange. Changed the loft/air flow a bit. Made the walls of the 'runners' much thicker, 10mm at the base and 6mm at the top (except the bit where the silicon hose clamps to). Did a test print in low quality, still took my old printer 10hrs but it gets the job done.

My dad has one of these, he had it reflashed by some mobile tuner guy. I think he used Prestige/Llama facilities when he was in Wellington. Something around $1k from memory. Everything was stock and apparently a pretty big jump in power, I drove it and really liked it. I can ask for more details if needed. Main thing I don't get is how its all over by around 5500-6k rpm, really feels like it should be a more rev happy car. Not sure if it's a limitation of the turbo size, or choked by factory intake/exhaust?

Bit more progress:

So this thing, I some how messed up the clear coat and after about 6 months it started cracking like crazy. So I parked it with the plan to sand back, since then I've painted half of another mx5 and that has not cracked so I'm confident I can get it right. Have mostly sanded back again, not the most fun job so I decided I should get back to the ITB thing. Last time I had it running with the first test of the 3d printed adapter and running on the speeduino. As above I accidently shorted and messed up the speeduino. At the time I built another one of the later 04.3d which is a nicer layout but uses smaller resistors and some other differences so I couldn't use the part as planned to try figure out what was wrong with the 0.4.3c Since then I think I might have figured out what is possibly failed on the original one but need to buy some components. For the adapter I wanted to redo it with a few improvements: - remove the cutouts in the flange. - thicken the flange from 10mm to 12mm. - change the intake ports to be oval instead of having the injector cutouts (since they won't be there), so it's a smoother air flow path. So here I am reminding myself how to use Fusion:

So when I bought this around a decade ago it already had the snorkel installed. A while ago I noticed rust staining coming from under it at the centre point, I assumed the bolt hole had started to rust and there was also a dent there. HoOooBoy did I underestimate it... I tried looking around for a good condition guard but had no luck so decided to try save it. Patches welded in, of course I ran out of gas half way. Spent lots of time making it flat again then primed and blocked (around 9:30pm in the dark because who has time anymore?). EDIT: I also trimmed a decent about off the lower section to clear 35's, added a lip for strength etc. 2k blackest black that ever blacked: Fitted again and it makes the 35 year old tired paint look terrible so will repaint the whole thing at some stage.

I've never heard of these having weak rods, this is very good info, I will now share it on every corner of the internet.

Really impressive work, nice.

Blue one must have been John Raptis' one? He'd been building that for ages. Love the in-car footage of yours.

Looking into "gen 2" Mivec loom pinout and was really hard to find anything useful, even trying the Wayback Machine on Archive.org to try see posts from the dead forum Mivec.co.nz Eventually found some references to Evo 5, FTO mivec, galant etc etc which has the same 4 plug ecu. Most of the wire colours don't match but it looks like Mitsubishi use a pretty universal pin layout. Like a 1994 mivec FTO v6 uses 2 pins for mivec solenoid, and one of those matches the 4g92 pin (35 but will have to double check). And all seem to have the same pins for injectors (1,2,14,15) TPS always seems to be pin 84. So will see how far I can get making a temp adapter to try run the still complete on the floor 4g92 mivec on a speeduino.

Also, the damn oil filter really didnt want to come off. Broke my filter grabber jobby thing: Tried stabbing with a big screw driver, nope just tore it up. Tried big ole pliers. Repaired the filter grip tool thing enough to get one more use out of it and finally gave way.

@Adoom lathed one of the ca18det conrods to match the thickness of the mitsi rod. Ive fitted the 4agze piston temporarily to see what it looks like in the bore. Much chunkier than the mitsi one! Fits nicely on the crank. Might need a little clearance, but depends if I change to ARP bolts. As expected the crank counter weights touch the Toyota piston skirts but I wanted to see what it looks like anyway. I scribed a mark to confirm where it touches. So ill bite the bullet and die grind a little off and test again.

Oh and yes that is a pink unicorn napkin.

4agze piston measures the same as the 4g93t, which was expected since they are both 81mm bore. Toyota have discontinued the rings so will have to get something else.

Bit the bullet and bought some new pistons from Toyota, thanks Mark if you happen to read this. NICE. Skirt on the 4agze piston is shorter, pretty sure the pin bore is lined up here. Made a rough template from the 4g93t piston skirt and lined up like this as a really basic estimate. Doesn't look like much need to be ground off at all! Top is meat. Much meat.
