jdm gsr turbo or usdm gsr turbo

jdm gsr turbo or usdm gsr turbo, right now i have a ls which swap should i do? looking for around 300hp. And this will probably come up but no i don't want to do a ls/vtec turbo

the usdm tends to be cheaper (more available), so go with that.

doesnt matter. whichever is cheaper.

id personally boost the b18b if i already have one.

Get the USDM GSR because its usually cheaper and has a little lower CR.....

how much cheaper? roughly
