Purchased the car in June 2000. Car ran great for many trips, up and back to uni.
In the way of speakers I decided to go with 7x10's. I already had one working Kenwood left from the Corolla days, and I ended up buying some Boss 7x10's aswell. These sounded pretty good and were pretty cheap too.
So I had my speakers but where to put them? My 'rolla had a parcel shelf (a very weak one) that held my speakers. The Supras didnt come with parcel shelves, but only with a rear hatch cover which I didnt have anyway. My first main task was to build a shelf.
I headed up
to WA Salvage to get some quality wood. Nice thick stuff. 9 bucks or something.
Make a few measurements, find a big bar of wood lying round to use as a pivot, and assemble. Easy really. And out of all of the mods, Im probly most happy with the way this one turned out. Perfect fit!
Heat and Starting
Around about the same time, intermittent starting problem. Car will just 'click' from the starter and will not turn the motor over. However, car will either start with jump from another car, or a hit to the starter = temporary fix :)
Take car to Lakeside Radiators in Joondalup to get radiator flushed. Reported 80% blockage in one of the tanks. Flushed okay, and car runs cool as.... for a week or so.
Supra comes off the road straight away to fix problems mentioned above.
We took the head off and had a look at the Head Gasket. Looks like a small blow near one cylinder. Blown Head Gasket alright.
After buying all this stuff, me and my Dad set out to complete the task.
We put everything totally together
minus the exhaust that needs to be welded to the turbo exhaust at a later
We think to ourselves what it could be and are stumped. Must be a dodgy head gasket. Head on down to Odin to try and get a refund on the 'dodgy' ACL head gasket. While we're waiting for the head gasket refund under warranty, I decide to buy another Head Gasket. George recommends another (cheaper) brand that should be just as good.
Purchase and take home. We then put
everything back together and make sure that we have done everything right.
Park the car in the garage and pull the head off. Damn, this is starting to annoy me.
Anyway, me and my Pops gets the head off and jeeez. Talk about a blown head gasket! The metal that lines the bore part of the gasket has been blown so hard that its curled up, and is bent. Even under 60lb-ft of torque of the head bolts! Good head gasket my ass!
Head on down to Odin and have a cry. I have a letter waiting for me from AAA Gaskets- the maker of the first gasket that I had thought faulty. They conduct many many tests to find faults in their gaskets. In the letter was a list of the tests and the conclusions of each. Apparently it looks like the gasket wasnt torqued down enough, and wasn't sealing properly. However out of good will they attached a brand spaking new head gasket! Just what I wanted! How did you know!? Heheh. George at Odin: "umm... you better turn your boost down.. I dont wanna see you in here buying another head gasket :)" (or words to that effect:) Hahaha turn it down? I dont think so! Seeya later!
Go home and have another think. If i were to put the engine back together, would probably have the same problems? Yep, would do. The compression ratio is just too high (head had been shaved), and would just blow again.
I made a call to ACL gaskets over east and have a GREAT chat to a guy that is full of info that I need. He tells me of a part that they sell that will decrease my compression ratio! Just what I need! Everyone else had told me that I was a retard and no part existed!
Order the Steel Shim and get it in
from Marlows a week later. Put it all back together as per instructions.
Finally get it all back together and
start it up again. Vrmmmmmm....
After running for about 20 minutes on the freeway, temp starts to creep up. Going to have to get me a 3-core radiator or something else that'll be nice and cool....
Therefore, next task- built a turbo heat shield. Successful. No melty after 10 minutes..... Only melty after 30 minutes. Make another heatshield for the alarm (no its not possible to move it), and Im yet to find the alarm soft at all.
