i wouldnt recommend the RB20... heck from what i have heard the aftermarket is small and isnt as worth it from what i have heard...even some of the j-ppl say they rather have a sr20 than a rb20... if u want rb then go RB25

also that 6speed s15 tranny i heard is weak stuff... i heard s15det with de tranny which is a 5 speed works out great

The S15 Tranny is not that that weak.... Sure it may not be the best but its does not break so easy.

my 6speed has survived many a drag launch with a 2step holding boost at 10psi from the getgo. and it's a direct boltin into an s14.

you will fail visual instantly. unless you know someone dont be idiot and try. why is it "better" to have NA? that is all personal opinion and driving style. there is no "better" motor. they are both good, just depends on what YOU want. rb20 is garbage..my personal opinion. better off with a CA or SR.

side note i remembered: a friend of mine said it will need custom header to clear steering shaft. not sure if its a fact. research is key.
