Can anyone tell me at what point I'd need to replace the other stock parts of my car such as...the tranny limit, block limit, rear end limit, clutch limit and anything else that I'd need to replace or upgrade upon meeting the 400rwhp mark.

 

after 400hp it is just a matter of time before stuff goes bye bye. I'm not sure about the tranny since my auto went out because of self induced failure. But the stock block will hold up to 700hp, internals well 400 is said to be the max but myself and some others are over 450hp at the fly. Safe tune and driving responsible like will keep you safe for a while. I think but don't qoute me the 5-speed is good to 400 but the clutch won't last esp with hard shifting. But plenty more people on here could chime in with more info..

 

Clutch will eventually go at 400hp or spirited driving with a supercharger. You can at least expect to replace that down the road. Rear end should be fine unless you start launching that car, especially in boost, you will start to weaken them axles.

 

When I do my s/c I'm just getting a plain simple Vortech non intercooled 8 psi and staying around 360RWHP thru my auto. After that, I'm going to do a full suspension package from maximum motorsports, I think thats a great upgrade after a S/C

 

get an auto, spool your rear, do your chassis and suspension,and get a motor too
