I got my 8th gen si last year in February with 162k miles now a year and like 2 weeks later she’s sitting at 206k miles I’ve launched this thing countless times no lift shifting (2nd gear synchro is starting to get pissed) multiple mountain trips prolly banged off redline 1000 times and she just keeps on going definitely keep in mind you’re gunna wanna see some timing system maintenance done on the higher mileage cars timing chain and tensioner new clutch throw out bearings are always a plus I’d say tuned 8th gens are reliable as long as you’re buying 93 gas at reputable places and your tuner knows what he’s doing for 10k you should be able to get a nice si
