Well, it's been a hell of a long time since i updated the thread on my car. A couple of months ago the car started running rough, using a bit of coolant occasionally and blowing a bit of smoke. A couple of weeks later, while driving to a mates house, i geared down coming of the freeway, and there was a dull thud, then massive vibration through the whole car, and a horrible noise.
My first thoughts were something in the gearbox went or the clutch had destroyed itself, but i still had a working clutch and could select gears. so i slowed down, pulled over, and got the car towed to my mates place. Upon dropping the sump, i was met by something i never thought i would see:
So, not trusting any part of the bottom end from this motor, i have picked up a 50,000km old 4agze bottom end through a toyota employee. I decided that while i was at it, i would give the motor a bit of a freshen up. At the moment, the block is off getting cleaned, decked, bored and honed, so i don't have any pictures, but i have accumulated a few parts for the build. Thus far i have...
Later model GZE pistons, 50thou oversized.
An engine gasket kit with .8mm MLS headgasket
Supertech stainless steel, black nitrated racing valves. They are standard diameter, but have been back cut and undercut to help flow.
Also i have gotten a set of supertech double valve springs, titanium retainers, vitron seals and stainless spring bases.
As the GZE intake manifold it one of the worst designed manifolds ever made, and have some shocking casting flaws, i have begun to clean the runners etc up to help with flow. This picture has been taken early on, but you get the idea...
Hopefully, i will get a chance to keep this updated, but between organising and building the motor for the MR2, building an evil KE20 with a mate (build thread coming soon!!), and leaving toyota in a few weeks to another workshop, it might be a bit diffcult to do. Any thoughts, suggestions, or advise to do with the engine build would be welcomed.
