i have a b18b soon to push 350hp it will also be my daily. do i need to get a new clutch? say stage 4? or will the stock one be alright? im not dragging it or road racing it but i need it to be strong and firm. will it be alright?

 

it will probably start slippin or blow apart soon, id get a aftermarket performance clutch and heavier pressure plate

 

stage 1, 2, 3, 4?

 

2 for a Daily.

 

and its going to hold 350hp? and 200 or whatever in torque?

 

yes

For street that's what u want. you could go to 3 IF you take it to the track on weekends but it will be hard in DD traffic.

 

yep, and you will be going through master cyl's and slave cyl's like crazy.

 

For clutch selection, you need to watch yourself on the terminology. The "stages" implemented by various companies are merely generalizations which are not standardized throughout the industry. A "stage 4" clutch from Company A may be only a "stage 3" clutch from Company B. You need to calculate your approximate torque and buy a clutch accordingly.

On my last setup, which made 315whp/216wtq, i ran an Exedy Stage 2 Cerametallic and loved it. It held the power on the street AND on slicks. I have since built a new shortblock and increased my goals. For my new setup i picked up a Competition Clutch Stage 4 sprung unit. It had the torque capacity i needed to meet my goals.

I think this question would be better answered in FI; although, i'll leave you to make that decision. If you post there, tell people of your goals and let them do the rest.
