Honestly I'm fairly inexperienced with working on cars (also new to this forum) and wanted to find out the basics of upgrading to a big turbo. I know this is probably a pretty common question (sorry) but I'm trying to find all the information in one place. I have a 2016 ST1 with about 118,000 miles, regular maintenance has always been done, and synthetic oil changed after around 5,000 miles. Would it be a stupid decision to attempt to go big turbo after having this many miles on the car? The only mods done are a turbosmart blow off valve (added myself) and a muffler delete (which to my knowledge do not have an increase on performance). If I decided to go the big turbo route I would most likely get the BNR71, from what I've seen it still spools up pretty close to stock but has a larger powerband (if there are better options I would definitely take those into account, high end power isn't really what I'm going for, but it seems like the best option) and I plan on running it on 91 octane (highest octane gas in my area). What kind of mods would I need to support this? Obviously I would need a tune (JSTuned has an online tune that comes with the turbo, not sure if this would be fine to run instead of getting dynoed) probably an intercooler also. I really only want to get around 320-350 whp and would rather not have to upgrade the block or clutch (from what I understand you really only need to do that if you are going above 400hp), and I do plan on upgrading at least the suspension in the future. The cost of the turbo with a tune is $1,860, what would the price be all together (rough estimate) to get the turbo (and supporting mods) put in by a shop? As I said I'm pretty inexperienced with working on cars and don't want to risk messing up my car. Also would adding a big turbo significantly decrease the reliability? I'm debating on whether to make my daily/only car more powerful or getting a miata or honda project to learn how to work on cars and for (somewhat) cheap fun.
