Hey SA 86 guys

Wanting to know if anyone has had any first hand experience with an engine rebuilder in SA,

basically I either need to find someone I can leave my car to and get my current 4AGE (16v small port bottom end/big port head) rebuilt or rip the whole engine out and replace (depending on cost's etc)

Ive been recommended TW Engineering so far, from mates who've had their engine rebuilt by them

Cheers in advance
