I wanted to go with Speedtech because I can get that pretty quick. My block is going to probably be ready next week to pick up. LA Sleeves and close deck, 11mm ARP head stud conversion, ported head, CP pistons, Molnar rods, etc, etc..
From what I have heard the Speedtech kit is nice other than the fittings. So I would probably work something out with all that. I would also only spend a difference between $500 to go to speedtech with same turbo.
Few reasons why I was wanting to switch:
My hood has vents and it pools water on the CHRA when it rains, thus rusting
Air filter rubs on my hood and makes some weird noise
Not a big fan of how tight everything is
And I want recirculating dumps
Other then that I would probably keep it.
