I'm getting ready to start my turbo project for my 2.4l. what i'm asking is if anyone knows how much the stock internals of this engine can take. i'm not using a pre-assembled kit, i'm doing all custom work and i wont be using a huge turbo - probably a t3 at the most. i'll be using the neccessary fuel adders - bigger injectors, fuel pressure regulator, maybe a new fuel pump, and engine management - so i'm just wondering how much i can turn up the wick without sending a piston through the bottom of the block.
It should be able to handle anywhere from 8-10 psi as long as it's properly tuned. I say SHOULD because obviously there is no guarantee, and there's always a possiblity you'll spin the #2 or #3 rod bearing, they're almost always the first thing to break under boost.
OK...i was planning on running probably 6-7 psi so that'll be fine...at least until i pick up some forged and decompressed pistons. i'm not sure about the fuel controller yet....i 've heard only good things about the apex'i safc so i might go with that.
