[baratinha]

Hey ,,, im new to the 240sx world but having a lot of fun already lol

im builting my motor and i need to know what is the stock pistons bore for the sr20det and do i really need to change the rods too or can i just change the pistons ?/ i wanna put the same bore as the stock ones ... But whats a good compression for like 400whp??? Please let m know what up .. Thanks mark o.

86mm. For 400whp you can use stock bottom end, your main concerns should be top end, management and turbo selection. This didn't deserve its own thread, use this next time AFTER google:

Like already said, 86mm, 8.5-1 compression. You can bore the engine up to 87mm without needing to resleeve the block.
