It’s like a restoration Mike. Taking a running/driving car down to the bare chemical soaked shell to bring it back in better form. At least you have the time to work on it. I miss wrenching on mine.
Have time ? What’s this commodity of which you speak? It’s December..our busiest month. The greedy bastards that run the dealership have the sales staff (Me) working today.
I sneak a few hours in obscure times..like this morning.This morning I pulled the rest of the bottom end apart. Looking at the main bearings that showed zero signs of wear, cussing myself for ever pulling the head in the first place.
Now the dilemma arises because of the letter T.
When you buy a 2jzge, you just bought a non-turbocharged version of the engine. Different crank, smaller flex plate bolt pattern smaller diameter torque converter bolt pattern. When you buy a 2jzg
Te, you just bought yourself a Supra MK4 engine. Twin turbocharged, Forged crank, larger flex plate crank bolt pattern, larger diameter torque converter pattern.
The one thing?.....I didn’t know any of that at that time.
When the converter guy built the converter, he called me and had me measure the factory converter bolt circle. I did. Just as he asked. When the converter came, he had built the thing to fit a GE instead. A bolt pattern About 1/8”-3/32” smaller in diameter than my flex plate.
Because I only needed to modify each hole about a 1/16” inboard, I figured I’d just elongate the holes to make it work.This flexplate has already been through hell already, drilled, cut, welded, ground on, and welded some more, I figured what the hell difference would one more set of mods make?
Again, as with everything I do, I start second guessing myself. The holes are now pretty big. I decide to weld washers on the back side to close down the holes and give some reinforcement to them. After doing that.....I look at the whole mess, and decide to just buy a new flexplate to fit the converter..When it gets here, the freakin thing is different,
and that’s when I learn about the differences between a GE, and a GTE. The converter pads stand off more, the flexplate is spaced different, and the crank pattern is smaller...by about............You guessed it...1/16”
When you look closer, the factory drilled holes in this thing...but there is no evidence of anything going on with the harmonic balancer like a SBF..you cannot see an imbalance weight. And there aren’t any holes drilled in that thing, anywhere.
So,...here I am. One flexplate fits, but it’s so freakin heavily modified, who knows what I’ve done to the factory balance. The GE flexplate is unmolested and fits the converter, but it doesn’t fit the engine. Despite that, It only needs the tiniest amount of massaging to get the holes modified so that I could bolt the thing on to the back of the engine.
But both flexplates need to be checked for imbalance now.
Which means I just added a rebalance to the machine bill. To an engine that didn’t need nothing until I got it here.
