220rwkw is way too optimistic... if you had a bigger turbz i'd believe it.

But as long as the car feels better, dont worry about high reading dynos. Driveabllity is more important

well yeah, i love the way the car feels now regardless of how many kw it reads. for the first time yesterday i almost lost control overtaking someone

feels great, im happy

wont let me upload the graph at the moment

will try again later

i think what insant is trying to say is the they've bodged up the dyno figure to make it look like a good dyno tune, also the stock clutch is good for about 180-190rwkw, whats it like at 220?

If the dyno used was Bresciani's then my 220rwkw was backed up at Selectmaz very closely.

It may be possible the turbo has been modified without being able to see the difference. looking forward to seeing the dyno plot.

Where the hell were all you buggers all weekend? Phillip Island was awesome.

have you changed the o2 sensor in the last 50,000 ks? goto autobarn, repco get a ford el faclon oxygen sensor, its a standard bosch or whatever brand it is. should take around 1 hour to install at the most. unscrew old one its on the exhaust dump pipe just after the turbo, right behind the turbo heat shield, cut the plug wires off, and replace with new one. The oxygen sensor has two same colour wires and 1 unique colour wire so you can't get it wrong. Match the two same colour wires to the car loom and the unique to unique on the loom. I was getting 250ks to a full tank. Replaced o2 sensor and got around 350 odd

The o2 sensor is only supposed to last 40,000 ks

yeah its around $100 ish. i paid $125 at repco for a AAA brand one i think.

nissan ones genuine are like $250 or something stupid so if you ask for the ford el or as japcab said that place in bayswater

what size is the 31 fuel tank, i think the 33 only takes like 55 litres tops

whereas the aus 31s and vl (im guessing similar fuel tank) took a good 65-70 litres.

does that sound right? the purpose of the o2 is to save fuel by giving feedback to the ecu, without it (as in dead after 50,000 odd or unplugged) the ecu just never goes into save fuel mode, well at least thats what ive learnt and read up on.

    • 2 does "sort of" applies, maybe......but looking at what parts would be needed for the swap to get engineered, registered, and insured, and basically that's everything under the car, the modifications the make it legal would be problematic and horrendously expensive, all for a street car that just cruises around and hits a few twisty roads on the weekends Also, from looking at the NSW rules and Regs, with all modifications that is required just to make the car safe and not twist itself to pieces, and then actually get registered for street use, may still be impossible nowadays As for 1, when you add in a fresh engine, fresh transmission, rear cradle and diff, tailshaft, suspension, brakes, cooling, and all the other fabrication required, your probably looking at up to $100k to do it right, all for a 20 year old MX5 that is over engineered and you would never be able to actually use the power it has on the street, much like your beastie, which I love, but you actually track that thing and can use all of its powers in anger, in a safe environment  Hell, the old Bogan Cruise Ship had more power than I could use on the street, and in hindsight, I went a bit silly on that thing, it didn't really need the 500hp it had for what I actually used the car for, it was fun, but basically unusable on the street if you value your licence  As for cams, yeah, I'll probably book it in for them to get installed and tuned soonish, like next month after MX5 Mania are back at work....... and yes, I've already sent a email to bin the turbo quote and quote instead to install cams and a new Fluidampr balancer that will suit the 2.5 better than the OEM 2.0 balancer that is swapped over for the 2.5 install, as the balancer needs to get pulled to time the cams it's a while your in there sort of thing I did think a bit about flex fuel for a laugh, but being na, and no where really around locally anymore to get E85, I've binned that idea, so no sweet sweet corn smells are set for the car I wish E85 was more of a standard fuel, it's better for the environment, better for tuning, plus that sweet sweet smell we all love As for fitting in the family, that's not needed, as everyone in the family already owns a car that can seat 5 humans comfortably enough, the MX5 is "my toy" As for buying a car that is already built, nah, I would rather pick and choose my parts, I enjoy the process, and in the big picture, the additional cost is well worth the enjoyment, and the occasional frustration, I get out of doing it, albeit with other people spinning the spanners, and me, just paying the invoice 🤣
    • Excuse me, but 2) does apply 1) Would also apply if you consider how much is spent in the alternatives. Also there's the option of 3), buy one pre-built that you can put your family in (it's me, it's my car)   That said, I went on a ~500km drive the other day. I didn't use anything more adventurous than 3rd/4th gear at about ~3000RPM and 50% throttle and I was going as fast as anyone has any sense doing on a public road, with enough grip to the point where I didn't want to go any faster. I was obviously under the limit of the current car etc etc. MX5 with 2.5 N/A to achieve the same speed would be more fun for any road scenario. Maybe consider cams. I wouldn't boost it. The use case is just not there and it won't actually make the car more enjoyable unless you really do plan on wringing gears from 1st to 3rd (at least) at 100% WOT on a public road to 150+kmh.
    • Great if: 1. You had all of the money for everything else that is required  2. Lived in a country where you could actually do this and drive it legally on the road Sadly, neither applies to me As for the turbo, I am having second thoughts, mainly for engineering/registration legality reasons and insurance  Not saying I've finished doing stupid things that I probably should do to the MX5, but boost, and V8 engine swaps isn't on the cards Strange, but true
