those mods won’t do much in terms of HP/TQ. maybe +/-25HP depending on the cams and the TUNE(cause you will need one to get the most out of those mods). its not worth it unless you are just looking for a few extra pony’s.
if you want cheap power then turbo your single cam. it can be done for chaep if you do the work your self and will have enough TQ to put most sr’s in the ground.
but if you really want an sr then save your money and look for the right deal to come along. g/l
i ment putting a dohc with those modes and pulling out my sohc. and as for sr i was thinking selling my car some time next year and getting a swapped car already just because it is so much cheaper to buy one already swaped. or may invest in another car like a skyline.
