just a few off the top of my head. 1. Starr Performance - V8 manifold $1.4k http://www.starrperformance.com.au/holdenv8_intake.html 2. C.O.M.E Racing - v8 manifold $2.7k http://www.comeracing.com/manifolds.htm 3. Walky/GroupA Twin Throttle Body Manifold $4.5-5k 4. Motec cross ram twin throttle body manifold $3k

yeah the motec manifold is sold by flowcraft now and would prob be the best of the lot... u can get a harrop/torque-power dual/single plane manifold and get a quad throttle body or some adaptor with a big single or dual throttle body on a hat and that will work just as good.. lot cheaper too. Nothing will beat the stock banana manifold for drivability tho, its built to be big and long and make insane torque low in the revs, which is a lot desirable for a real street car... but obviously it has pretty bad power limits after 200-210rwkw

best bang for your bucks is a harrop and quad tb top hat. can be made 2nd hand for as little as 1200 or new for 2k and only makes 3 % less grunt than walky throats.

yeah i can. if u want a harrop its a 3 month wait but can get u an active just about straight away. i used an active on mine and it made **** loads of grunt. the top hat with all the sensors etc i can get for 850 and the manifold with efi holes is about the 850-900 mark. so about 1700 all up. with sensors
