    That will be me, I've moved to Sawston :p There is another white Altezza in the area though so could be either of us

    Well as the Altezza has become less of a daily it has been time to get a second car. Although I did get some new wheels which I fucking love:

    RE-Amemiya AW7s by Desmond

    Now I know RX7 purists will tell me to fuck off as they are wheels for RX7s but I don't care, let me be happy.

    The thermostat seems to be stuck as it takes about 25minutes to get to temperature, I'm creaking on full lock so probably worn ball joints and these tyres are way too wide for an NA 4 pot so I'll give her some TLC over the coming months.

    Now as I was after a second car I was thinking practical, 4 door, plenty of space. Like the Impreza wagon I had, which was NA so low maintenance and plenty of room. But unfortunately I have also been watching way too many Hot Version episodes on the Youtubes and got hooked on the Techno Pro Spirits MR-S... so meet my new car, nicknamed "The Banana Shitbox"

    86285822_2550932488368659_3806230314414505984_n. 85189995_162904641825887_2136776101257543680_n. 83904310_811741722677244_5216502157703905280_n.

    As you can see she isn't a show pony. The most serious concern is steering vibration on bumpy ground. It might be steering rack bushes but I'll jack her up when I have time and see if I can find out for sure. It also came with an engine management light which no one has been able to read as its a Japanese import, but using the bluetooth adapter, Torque pro and a custom string I managed to read the fault code of an O2 sensor.

    The car itself is pretty standard, although has a J1 front/rear lip and sideskirts and an Abflug(?) rear wing. Also has a reeealy old HKS sticker above the exhaust, so having a HKS backbox could be cool. Again, need it jacked up to really see what I bought for £900.

    I know the Mk3 MR2 is hated but it is like a go cart to drive with amazing handling, and at that price it is a 7/7 from me.

    More woes.

    Was swapping out the thermostat on the Altezza, took a bit of time to wiggle it out but got there in the end. Was bleeding coolant, had the engine running with an easy bleed funnel to get it up to temperature and then poof, engine died. EFI fuse has blown like it did on the drift day. Now whenever the ignition switches on the fuse blows instantly.

    Electrics are probably my worst skill so learning stuff as I go. I ran out of fuses so waiting for a bunch to arrive and then I can start troubleshooting. The plan of attack is:
    - Unplug everything in the engine bay, see if fuse blows. If it doesn't, plug stuff back in one by one until it blows.
    - Fuel pump. Test resistance across terminals, turn on ignition with it unplugged.
    - Cry
    - Highlight everything on a wiring diagram that is remotely connected to the EFI fuse. Learn how to use a multimeter and try to find a short.
    - Hire a priest to spray it with holy water

    On the MR-S front, there is a aux pulley with a fair bit of play, a slight clunk when pressing the belt (probably tensioner) and the belt itself has split. Also ordered a replacement timing chain tensioner in case that is what is making the clunk (I'm hoping it isn't rod knock).

    This week I hate cars and am considering becoming a cyclist and swearing at drivers as I cut them off.

    Electrical problem on the Altezza solved, was a short from a plug the I had cable tied out the way when ITBs went on:

    87066456_601015867127089_2496510016371032064_n.

    Knocking on the MRS identified... is indeed rod knock. Pulled the pan off and there's a lot of play on cylinder 4. Need to get a 12 sided socket piece then will get the bearings out and see how bad the crank is. Might try and clean it up and put new bearings in as a short term fix. If the crank is shot will be cheaper and easier to get a new engine in.

    After not driving the Altezza for a few weeks, I forgot how great it is to drive. Just need to get the hardrace RCAs installed and correct the ride height

    Having owned a few sxe10s and zzw30s myself I can see you like underrated Toyota's
    Get a 2zz in the MrS, can be done nice and cheap and it completely transforms the car.

    Have you driven a 2ZZ MR2? With the bearings needing to be replaced I expect the engine will be a ticking time bomb so it will end up being a simple 1ZZ replacement or going 2ZZ. My "issue" is that the 2ZZ seems more like the 3SGE and needs to be revved to get it going, whereas I like how the 1ZZ had a lot of umph low in the range. But that might be because the chassis is so light so light? I'm new to the ZZ world so probably need to go and experience it.

    The techno Pro Spirit MR-S has the 2ZZ and it sounds like it has ITBs on the Hot Version episodes.... I think it needs extra firewall clearance to fit but that would be a lot of fun....

    And I bought this as a cheap daily so I could keep the Tez in the garage :cry: I have no self control

    when I was in my early teens some one on our street had an MRS in that exact colour with the same wing. I thought it was the coolest fucking thing ever.... still do. Shame to hear about the engine but think of it as a chance to add more personal touches. I've seen one with the 2ZZ swap at our local (manchester) cars and coffee and the guy seems to think it was the best move ever and I've got to admit it does look right at home there.

    Well it has been a while, not a lot has changed on the car considering how much time I've had.

    First up: Tail light covers. They are cheap fiberglass ones so are not the flushest of fit but I quite like the change for now. I tried painting them myself with rattle cans... now have much more appreciation for car painters.

    tezrear.

    The front right wheel has an air leak from the barrel, bit of a pain as that is tyre off and re-sealing. I don't want to split the rims just yet as I'll get them fully refurbed at some point, and considering their age I don't want to fuck anything up.

    Next up i an NRG steering wheel. The DW suede one got trashed pretty quickly as I use it daily and it ended up being gross. I couldn't justify the cost of a Nardi, I don't feel like they are worth it? So wen't semi-budget and got a leather one that will last longer with my sweaty hands

    118849428_399411594373288_9212799583998587248_n.

    The next learning curve for the Altezza is getting a gauge installed in the dash somewhere. Being on ITBs and Link ECU I want to keep an eye on some parameters, particularly AFR. With a Link lambda controller already in place, the best solution seems to be a CAN bus gauge. Went for AEM as it seems like a decent option for the price compared to plug'n'play gauges for the link ECU. The basic setup is:
    - Spliced AEM harness to separate power from the stereo or something, and the CAN+/- to the ECU.
    - The CAN wires will be spliced in to a Link plug int he CAN socket on the ECU.
    - In the Link ECU, replicate CAN IDs, frequency etc to match AEMNET IDs. Link only use 6 CAN channels and bundle different parameters in to each ID whereas AEMNET seem to use a separate ID for each parameter. So I can get 6 different data channels out of the ECU which is more than what I need.

    118711120_1101269143650263_3053030705834239278_n.

    The pain here will be the wiring, and as the ECU is in the engine bay I need to feed CAN wires through the firewall.

    On other news, the MR-S battery drains within days due to the immobiliser, so got a quick disconnect switch for the battery rather than fixing the actual problem. Other than that, it drives great with new shocks, OEM wheels and fresh tyres
    Goody.


    And now for the reason why car progress has slowed down... this is Elphie, she still needs to learn how to pass me the 10mm socket
