    So I've had an Alto Works around the track, all of my suspicions are correct. The cars intercooler is far too small, so Robert is going to make me a charge cooler when he fixes his Lotus

    So when that eventually arrives, my mapper has a new file to load on. So the car makes 15psi of boost at 2800-3000rpm and then (because it's limited to 64hp) pulls the boost off really quick, so basically the new map is going to change the target boost to 15psi all the way up the rev range. But I'm expecting the turbo to struggle higher up in the rpms. With a good intercooler and an exhaust modification I should manage to get about 85hp, maybe 90.

    BUT YOU'LL BLOW UP YOUR ENGINE

    No

    So cylinder pressure is complicated, so rule of thumb is that high boost at low rpm is what bends rods generally. This is because you have high cylinder pressure occurring for a long period of time. If you increase rpm, you shorten the time the high load is applied. The theory is that if the load is safe to be applied at low rpm, that same load can be applied at high rpm - however you can't rev to infinity and there are many other factors. but you get the gist. I really don't think I'm going to do any damage with the standard turbo anyway, that's a given! lol

    some pictures of the practice session:

    Road class car, no modifications allowed except induction and exhaust are free, as is suspension as long as it's using standard mounts. Good fun on a damp track, I'd have like it if it had been raining a bit more, the car is very controllable.

    The car ran absolutely fault free - as expected.

    Happy new year to anyone reading this on the day!

    Got myself a mushroom filter so I can hear the pigeon/dose/whatever you want to call it. I don't think heat soak will be an issue, but I will fabricate a shield to replace the standard airbox.

    2019 plans maybe get a bigger intercooler and fit a fan to it or something, it's barely suitable for the 64hp it has as standard! (one of the many limiting factors to Kei cars)

    I've also got myself an English Kenwood radio, had to make some modifcation for the wiring using Vauxhall/Opel/Holden wiring kit, but they're all pretty generic. I'll upload a wee guide later for that.

    Brilliant, the modifications are endless

    HKS have a gazillion different types of exhaust for them, CUSCO, KC-Technica have just about any part you can think of listed for them too!

    the downside is I have to pay 20% plus customs to import any parts and the postage is horrendous However BC Coilovers here in the UK can make me suspension at a reasonable cost so may go down that road in the future.

    Maybe you'll like this. It's a pamphlet I took from Autobacs a few weeks ago in Japan.

    Small update while I'm still waiting for the authorities to register my car.

    The final piece of the puzzle to pass its test was completed a few weeks ago by a company called Lockwood International, based in Leeds. they did a cracking job replicating the standard dial face. My importer (BHP Imports) installed the dial face for me.

    So, this is the ONLY Alto Works with a MPH speedometer display anywhere.

    Here is a picture of it installed, I think the needle is slightly off but that's an easy fix!

    Maybe be able to pick the car up in the next few weeks.

    Oh yeah, 2Sexy will dominate Moog's new ride! Power to weight means throttle response, need hell sticky front tyres but (RE003 overpowered)! Maybe slicks? Also for Moog, early Hyundai 2.4L Sonata Auto's have a early counterweighted crank 6 bolt SOHC 8v 4g64 which can be combined with the 6 bolt 4g63 DOHC 16v head/conversion pistons to make 500HP+ pretty cheaply!

    Daihatsu's term for Toyotas VVTi, looking at some Sirion Rally2 stuff from UK(ecu/exh cam for 81kw)! Maybe even Blitz 5psi supercharger kit from Yaris, same design eng just 1.5L for $4500AU!

    Nice! right width, wrong length!

    I've no experience with DVVT :O

    Unfortunately not as the speedo operates on the canbus wires. We've tried a canbus chip but can't get it to work.

    we have removed the speedometer face and sent it to the professionals at Lockwood for a custom mph scale

    Can't you do that conversion yourself?

    So... a slight update which proves just how slow it is to get a car road legal.

    Having problems with the speedometer just now, as it MUST be in mph to pass the IVA test. All the traditional chips and signal changers don't work. huzzah so it's needing custom stuff... that's been one month and 2 days. Everything else has been done, I'm literally just waiting for that conversion to happen then we're good to go
