I know this is a turbo forum so if you have to kick me off you can but there are no active forums for N/A motors and eveyone here has always been really helpful in the past.

I have a 92 2.5 N/A motor that I have built. Listing my mods and what HP I think or have heard they add. I am looking for constructive criticism on other things I can do and also how much horsepower you think I have gained over stock compared to my guesses. (This is for a dirt circle track car) I can only run factory parts. Rules don't say what I can or cannot do to the factory parts tho. Engine has been fully rebuilt and so my total HP is based off of the factory base HP rating of 100
