i don't know all that much about turbos, so bare with me if these are stupid questions: what is an equal length header? what is so great about it over the other header? does the equal length header come with the base kit now? and what is that bung/opening/fitting on the top of the 2nd pipe for?
The equal length header improves cylinder scavanging. So you will make more power, and the turbo will spool up faster. The flange on that runner is for an external wastegate. The external wastegate option doesnt cost any extra.
ok, i see. so what are the advantages and disadvantages of an internal and an external wastegate if i had the base kit with the equal length header and the turbo upgrade (ar.60 int)? the base kit does come with an internal wastegate, right? oh, and am i able to purchase the base kit with just those two upgrades without having to purchase the water-air intercooler and 3" downpipe (by the way i have a 2002 ex, if that makes a difference)?
may as well add these questions to the list while i'm thinking about it: does the kit for the ex still require modifying the exhaust? if so, could you explain exactly what needs to be done (i remember a picture you had on a different post, but didn't really understand what needed to be done). i understand that the kits are shipped with a setting of 5psi, but would it be possible to ship them set at 7psi (or am i able to do this myself without a boost controller)? do i need to purchase a boost controller, boost gauge, and turbo timer, or do i not need any of these? and finally, am i able to get the "SF" logo on the air-air intercooler in a different color (like black or red)?
i apologize if these questions are getting annoying, but like i said, i really don't know too much about forced induction systems. i just want to have as much info as possible before purchasing a kit.
The air-water kit is an upgrade just like those. so you can get any combo of parts you want.
The external wastegates are easier to adjust and prevent boost creep (which i havnt really experianced with this kit/internal wastegate)
You dont have to do anything to make the kit fit an ex, we made the downpipe to fit the EX also.
The kit comes with a bleed valve, which allows you to adjust the boost setting. With the valve closed, it will make 5 psi. You just open it slowly to set the boost setting.
It is a good idea to get guages and a turbo timer, but they are not "required".
We have red available for the logo on the intercooler.
I am here to answer the questions, and i dont hold any bias towards anyone. If someone doesnt know what a piston is, i will still do my best to help them out.
dont know if this was mentioned in a previous post, and if it was, sorry..but if i were to drive down (or up? err, whatever way from the bay area..heh) to lancaster would u guys be able to install the kit, and for how much? i want to get one, just need to save up some money.

just need some clarification here: so if i go for the external wastegate option, sf will disengage the internal wastegate and add all the external wastegate parts for free?
