^^^ exactly; the HF manifold is NOT gonna be your weakest link with a stock block DI would think that the HF/STD manifold would be a good choice as it is so cheap and easy to do. One thing I really like about it is that at a glance the engine bay still looks rather stock. Obviously there will be no worries of the manifold cracking. The only real concern of that manifold would be the HP limitation, I'm not really sure what that would be but I'll bet it exceeds the limits of the stock bottom end...

You realize that because its a t28 inlet flange; your manifold options are narrowed, right? A cast manifold is probalby gonna be your best bet... search eBay for 't28 manifold'
actually; i think both of your threads could of been easily been combined... and you didn't really provide enough info for anyone to help you make a decision...That thread has very little relavence to this thread dont you think?? My wanted thread was so i could compare the cost of getting a manifold from the states compared to what i could get hold of over here in the uk. Im currently buildinga z6 with vitaras and tt rods etc so the block wont be stock. if people had the choice of the three i mentioned what would they go for and why?
