Ok, my understanding is that its really hard to bore a 5sfe because the cylinder walls are so thin. My understanding is that its not even worth it because its to easy to bore to much and weaken the cylinder walls so bad that it could cause cracking or stress fractures. Or that what you could bore out wouldnt make a big enough difference in the end.

Well me and a friend of mine where talking the other day about how i want to take my spare 5sfe and do the 5sfte upgrade. I was telling him that i wouldnt be able to run to much boost because the engine wouldnt be able to handle it. he said that i could bore it out and put sleeves down to make up for what was bored out and i would be able to handle higher compression and would be able to run higher boost. Now he is a Honda fan and has been working on cars since he was like 10 and has been building Hondas since he could drive. he really doesnt know a lot about Toyotas but he is a fantastic tech.

Can this be done? Has it been done? and what kinda of boost gain has come out of doing this kinda work?

well, now i thought that if i bore it out, im going to have to get new Pistons because after the bore they will be to small. That another way to go about it was to sleeve after the bore and the old pistons will fit again. is this not true?

no its true. you will need new pistons, but they are the same price as regular pistons even if they are oversized. and its a great opportunity to upgrade (forged?) so you know you have a solid bottom end for what ever other overhauling you want to do.

The question is not how far. The question is, do you possess the constitution, the depth of faith, to go as far as is needed?
