Just out of curiosity I was wondering if anyone has ever successfully swapped a TH400 into their WRX. I've seen some articles about it in the past, I've also seen articles with TH400's being used with a 2jz and other various imports. From the research I've done I haven't seen a specific kit for it either. The reason I bring this article up is cuz I'm done with driving my WRX on the street when I built the car I wanted to have a nice street car and I nice drag car best of both worlds type of thing. Quickly learned that is not possible. I've blown 2 motors on the street, grenaded my 5 speed on the street, grenaded my rear diff on the street and to top it all off I had my motor catch on fire on the street.. So I'm over the idea of having a fast street car but not over the idea of the drag car.. If no one else has ever put a TH400 in their WRX that can shed some light then I might make a thread down the road of me doing a TH400 conversion. It seems asinine to spend over $6,000 on a 6 speed when I could get a TH400 for about $1,000 and a stock TH400 would hold 600+hp all day.. The only reason I'm even considering a TH400 is cuz I've made my mind up that the car will not be a street car anymore.. If anyone wants to chime in and have a discussion feel free! Down the road in about another year or so I will be making a thread of the conversion!
