Thanks for being concern and worried about my engine... I also understand the theory behind all the stresses that will be faced by the pistons, crank and conrod. Including the block and head itself... I am a person whom strongly stands on the engineering side. Just like 4G93 and 4G93t engines. They are designed to take different load and worked under different envronment... Oil squirter and the low compression pistons with internal offset are very good examples of the same engien but different application..

However, I've already learn and prepare to face the worse consequences... There are few reasond why I'll go for BOT.
1) Enjoying the improvement and collection of item. As through this way, I learn more...
2)Would like to go around and learn about how things work in practical application compare to theory.
3) can hang around and play aournd and understand more about the limit of an engine before transplanting into a more power engine...
4) Can delay the prooject if necessary, e.g. no money. U pay part by part. Not like transplant. Have to pay everything upon installation.


Anyway, thanks for the input again...
Speed Horizon,

Well, if you want to learn more by paying more, perhaps you can go for it..Good if you knwo the engineering side. I have great interest in cars and previously was working in manufacturing section supplying metal parts for Toyota and Perodua...:) Trust me the testing and stuff really have alot of reasons behind it.

What you can see is oil squirter and bla bla...what you cant see is material properties and how it varies among each other. What is forged and semi forged and cast iron. Even cast iron have different stregth,mettalurgy and so on...ok i think i talk too much on this hehehe

The spec that japanese had was designed and tested for NA. If you want to go step by step for BOT, i would recommend at least you change to turbocharged spec pistons(not some na piston) and race bearing before you start all project. Think it would be safe then. Good luck
