Engine rebuild project! Share your ideas...

[Bean]

as said considering you are aiming for a very mild rebuild, there is nothing wrong with OEM parts. Also taking into account the reliabilty of Toyota back in those days usedbparts will cover you above and beyond what you need.

Seriously there is no point in any kind of forged parts as long as you stay below 160hp, which you will keeping the ECU.

As said you might be better off considering buying a complete engine in good nick and going from there. Refurbish that with new pumps and bearings and there won't be anything to worry about for more miles than you likely to throu at it.

If you can give us a better view of what you are aiming to do with the engine we can give better advise (dailydriver, present running 4AGE, trackdays, etc...)

Also a location would be nice as markets and availability of parts are very different around the world.

Last but not least, consider this I'm currently building an engine with the potential close and around 200hp and spent less than 3k$ excluding clutch and flywheel. That's a complete engine top to bottom with custom pistons and so forth... you are welcome to read my project thread for more details.

Also can you shed some light why you want/need to stick with the OEM computer?
If this is a necessary evil you can't avoid I'd recommend a recreation of robokils early build mentioned earlier in this thread.

PS: getting everything new will blow your budget considering a new crank alone is half of it or a third if you get a good deal.

PPS: get yourself a complete engine in good condition (usually less than 500) and save a lot unless you already have one. As they are many pieces still missing on your list like injectors intake manifold, ignition system to name a few
