  1. That stuff is so thick, I managed to pull most of it off by unpeeling it off at one corner, and just rolled up into a... roll when it unstuck off the floor. Hah. (On a hot day)

    Thinner stuff is definitely total win to do it on a cold day with an air powered chisel, smashes the shit out of it in big slabs.

  2. i dont really like the quad headlight. to meny people do them id rather be different

    In relative terms (compared to other people on the internet) yes, twin headlight is a popular mod. (because it looks about a million times better)

    In absolute terms, 99 out of 100 people on the street probably havent seen a twin headlight KE70 before.

    Definitely quite pricey for a swap though!

  3. A car with a good factory gas tank position is an MR2.

    It has it dead centre in the car, just underneath the gear lever.

    Long and narrow tank as well, so less susceptible to fuel surge.

    So despite being pretty much as close to the driver as possible, I've never heard of a crash involving gas tank rupture making the driver explode.

    I guess if you're in a crash bad enough to damage the tank, you're likely a pile of mush before you catch on fire anyway :D

    I must say it gives me the shits, where a good shunt in the rear of my car would likely make my gas tank go pop.

  4. So the top two covers off, intake cam out, all headbolts undone?

    I took one off two weeks ago, lifted straight off by hand.

    Maybe theres a bracket or bolt that you havent noticed thats still done up.

  5. Man it really is a mix of emotions reading KPRs build threads...

    The fabrication skills and smarts are equal parts stupidly awesomely impressive and mildly depressing.

    Impressive because they're awesome, depressing because it would take me a billion years to make something half as good as the stuff he bangs out!

  6. My motor since being rebuilt has spent a shitload of time idling with no load on it, running stupidly rich, and all sorts of other unsavoury activities.

    I took it out for its first good run pretty much straight to the race track, and beat on it till it broke (loose valve guide)

    Apart from an error with machining, there were no discernable problems based on having had the engine idling for long periods or otherwise.

    Beat on it to redline every gear, synthetic oil.

    I've got the head off at the moment, and there's no damagey looking wear patterns on the bore, or anything like that, everything seems fine, despite having done the worst possible thing for a new motor, according to current wisdom.

    I guess a compression test would perhaps show the true story though. (Or pulling the pistons out, but CBF)

  7. Breaking in an engine seems just like choosing an engine oil.

    Everyone's method is divergent not inclusive.

    As in, "I did this and it works fine, therefore its what you should do"

    Doesnt mean that doing something else wouldnt have acheived the same result.

    What happens to factory new motors?

    They dont get any special oil or run in for 1000s of kilometers in a particular way.

    What I would be interested to know, is who has run in an engine and then had it FAIL, or glaze the rings or whatever, what were the symptoms, and how was this diagnosed as the issue.

  8. I'd say turbo bluetop is best gains for dollars spent and ease of conversion.

    So long as you dont mind munching the odd T50.

    Beams is a lot of work into an AE86.

    As a general rule I'm a fan of spending the $$$ on bolt on bits, that way if you blow your motor up your not thousands of dollars down the drain. Just stick another block in there and you're good to go.

  9. Car was having issues with brake bias being too rearwards, so am going to use a Load proportioning valve from a Toyota Estima as a brake bias adjuster.

    These are normally connected to the rear suspension, so that as the static ride height of a van lowers (with more weight) it adjusts the lever which adjusts the rear brake bias.

    Safety wise it's better than the wilwood equivilent because it takes a pressure reference from the front brakes, so if you've got no front brake pressure due to failure etc, it will send full braking power to the rear instead of limiting it.

    So it just needs a threaded adjustor made up, instead of the lever pivoting it. Factory parts / being cheap / pick a part FTW!
