Hi I am new to this forum.
I have a 1990 Toyota 4 Runner which I have owned since it had 50000 K on the clock. It now has 427000 K 0n it. I have done a restoration on it and have been over it end to end. Unfortunately it is fitted with a 4YE engine coupled to an Aisin A340H auto trans. Consequently it does not have a lot of get up and go.
I have completely rebuilt the engine and the auto trans. The engine had crank grind, new pistons, Rings & bearings,Timing chain and Cylinder head rework.
I was amazed to find that after all those Kilos the cylinders had no wear. No lip and in fact in places you could still see faint traces of the original hone marks.
I know there will be some that will tell me to do a transplant but I am one of those that likes to restore to original. That does not mean that I am not prepared to make some modifications that may contribute to an increase in power. At the moment it does nought to 100K in 6. That minutes of course !
Any un rude suggestions will be appreciated.
