Hey team dont post here but thought id put in my two bob.
Jake is the best in my opinion but you wont get your car in now till after December. I know cause I went in to see him today and thats when He could fit me in (bloody summernats).
Joe at skyline performance is also good, Ive had my clutch done by them and havent had any probs.
Canberra motorworks next to skyline performance is also very good with performance cars. I know that many of the engine rebuilds done at the performance shops in mitchell actually get done by these guys and then sent back to the shop.
But as Mose said when things get too hard many of these shops just get Jake to try and fix it.
