ok im going to give my oppinion on this subject. i have limited dealings with turbos or superchargers but from what i understand the bottom end of the na motors is the weak link, so my though process goes towards using the bottom end out of a srt dont know if this is possible or not, iknow there are some differences between the 2 but i do believe the block will bolt up to the manual trans (hddp a lil help please). so my idea would be to get a complete srt long block or complete motor who cares, you can always sell off the other parts, bolt the na junk back up top and have a 20 psi bottom end ( i do believe thats wht ive seen some of the srts running) but at what point would it just make more sense to take that srt motor and run a stand alone??? i'm waiting to see what happens to hddp an latana tx i want the power but don't want to waste my money, and i want to retain my manual tranny, oh and anyone seen a stage 2 clutch cause that would be a major need in doing something of this sort?
