I usually stay quiet and let people do what they do, however you stepped into a fantasy world, you understand nothing of cars or their mechanics, all you understand is the bullsh!t other morons feed you. Try and do you're own work and make it a quality peice, instead of paying someone else to do it for you. Your whole experience is based on asumptions. Well sir all i have to say is that assuming makes an ASS out of you not me.

I am not meaning to offend you here, but just curious. Why the flame bro? He did come at you a bit aggressive and challenging and make some assuming statements that may not be true. But as we all know he actually has learned alot and pioneered the first working G2 Legend turbo setup shown on these forums, which is an accomplishment, whether he did the work or someone else did. He is now doing all of his own work, and making those new manifolds with his own hands. His new design may not be the best possible, but honestly it will work, and it will work decently well. And it's not like there are other options people have to look at. I'm not taking any side of any arguement, just stating what is there and my opinion.

Turbo spool will still be horrid, and you still haven't explained how you will setup an engine management system. Without an EMS or ignition timing control in conjunction with your SAFC you will be hard pressed to pass 280whp before you start detonating. This is a big assumption, but from what I can tell you merely made the manifold a
slightly better design and still are going to have major spool problems since the distance between the combustion and turbo will be 2-3 feet in a little 3.2 liter engine. I hope it works but you still are doing it half-assed. I mean no offense but Gary DePreist's manifold setup is the only way you're going to make a drivable turbo legend that is worth the money, at least make the manifolds come out towards the front, use two smaller turbos and cut the piping distance by ~2 feet. You can reroute wires, using "I'm avoiding wires" as an excuse is not good. Prove me wrong, although I won't be holding my breath.
You have some good points and some assumptions here that may not be true either. The manifold design is much improved, not slightly. It should spool and perform fine. It is true that the closer the turbo is to the exhaust the more energy is available to spool it. However there are many long tube design turbo manifolds which take a decent length before reaching the turbo, and they work great. In our case, the limitation is space. It's not that easy to design something that will even fit at all in the Legend. If anyone would like to make constructive criticism, the best thing would be to draw up and suggest actual possible manifold design ideas that would fit and work to improve on what he has. It's not that easy.
Also do you or anyone have pics of Gary DePriest's manifolds or details of their design? I would love to see them.
I also agree on the engine management point. Especially the FMU part, an FMU is not very accurate at all and stresses the injectors at higher boost with extremely high fuel pressures. A better AFFORDABLE setup would be an safcII with a walbro 255hp fuel pump (<$100) and larger injectors like dsm 450cc's (<$100). However he has no obligation to explain how he will set up an engine management system for us. He is making a turbo kit, that is more than enough on his part, and alot in itself and something to be appreciated becuase thus far there hasn't been one, ever. Most turbo kits do not come with any engine management, you are on your own to pick yours. But personally he is planning on testing the limits of his safc and fmu setup. An SAFCII and fuel pump and larger injectors can usually support up to 10-12psi of boost okay on most hondas. On a Legend that will be almost nearing the safe limit on stock internals for a reliable pump gas street car anyway. The next step doesn't need any explaining, its common sense. It's the same thing as on any other car. You go standalone and a fully built motor, and very few Legend owner's are going to take their cars this far anyway. The SAFCII and other piggybacks are not ideal and crude methods that do work, but how many Legend owners are ready to drop an additional couple thousand for real engine management and then 5-600 for real tuning?
Just my opinion.
