Limits of a 4th gen 3sgte bottom half Options

[teamchancery]

I have seen a dyno of a 4th gen 3s (caldina)making 400whp on stock internals.However with these things you never know how long these engines last for.My question from either personal experiemce or other persons experience .Whats the most power made on a stock bottom half 4 gen to be driven around daily without breaking
I have a 4th gen and changed the pistons cause orginals cracked but didnt have the extra cash to buy forged rods.So i got some JE pistons but the 4th gen rods look so much smaller than the older mr2 and celica rods that with my new build i am deciding to build it to around 350whp and leave it there cause the rods got me nervous

Ok, I rechecked my Toyota EPC and the gen4 rods have the same part number as the gen3 ones. So, if the stock gen3 rods handle your power goal, the gen4 will do too.

As I said, the crankshaft is the same for all gen2 gen3 and gen4. The gen1 uses a different flywheel bolt pattern.

For the pistons, the EPC part numbers are different because of the compression difference, but you can use any 3sgte aftermaket pistons in your gen4 block.
