yeh, its' all SR20 motors meaning it's all 2.0 so same displacement.
I would recommend getting the DET motor cuz it has more potential to extract more power out of it since it's got better compression ratio and pistons that will allow more power later on.
the total amount of money wise..pretty much the same, the JWT lists at $3500 and install probably another 1k-$1500? and that's not intercooled i believe but does come with a programmed ecu...for the DET, the total job without ECU but fmic, same price...pretty much depends on where you go...i read it on the post some where that there is a place in SD that's doing the det swap, everything with lots of jwt parts for $2800??? that sounds waaaay to good to be true....my thing is, in life, u get what you pay for...but that's just my opinion...i truly believe that to get it done and tuned the right way..it'll be around $4k-$5k and save for another $1k or so just incase
