Pure HKS quality. There is a lot of parts but everything is well made and relatively simple to install. Note there will be some differences between left-hand and right-hand drive, but none of it is complicated. The car is a dream to drive and made great power with the 110mm pulley w/o restrictor, stock rev-up engine with fuel upgrades. Car made ~130hp and ~100lbs/tq, tested stock and then tuned on the same dyno. Very happy with the purchase and the work it took to put everything together.
