Just a garret GT2871R as far as I know. The inlet is massive compared to the pulsar one so wanna keep it as I assume there is some advantage to having a big hole (cough). I did think about shaving the gear box but I'll see how I get with the spacer first.
Yes, you're right about the studs. Got some on order too. The originals might be OK as I've measured up and considered the 10mm loss but don't want to keep being pushed back by waiting on others. So sick and tired of running into small problems and having to wait for some poxy bespoke part or the like.
Anyway, should be ready mid next week. I'll post up some more pics for an update.
