Engine rebuild project! Share your ideas...

well if you have to use the stock BLUETOP ecu, there's not much you can do to be honest. Yes you could fit slightly wilder cams and time them as good as possible with some cam gears but it'll always be down on potential performance. So what I'd do is have the head worked on (nothing serious just a cleanup) and build the engine with used crank and rods. Get some oversized 81.5mm highcomp pistons (OEM Toyota) either redtop (along with the matching crank and rods but used) or EU spec 10:1 bluetop.
Lightend flywheel etc..
considering your budget and what you have - a used engine in good condition might save you a lot of hassle anyway.

To be honest if you can't/don't want to change the ECU and already have a running 4AGE spend the cash on suspension drivetrain parts, interior etc... you'll have more from that than a building a stockish engine.

This is all my point of view obviously.
