well the 238's mate up good with the 38R. Your good for the low 400 Hp level. 250's obviously flow more and you are looking at the 500-600 hp with a bigger turbo. I went with the 250's cause I will most probably step up to the 42. my 250's will max out the 38R and back pressure is going to be an issue. I will have them tuned down to suit the turbo.
