What are the most common problems with the SR20det? and also problems exceeding the 350hp + mark?

 

When you get into the high hp ranges you need to worry about the internals not handling the power, and also you need to make sure you are supplying enough fuel and air.

I'm not really sure what common problems there are though.

 

For fuel i'll be using walbro 255 and for air going with the 300zx MAF

 

Perfect.
