Does anyone have a good diagram of the vaccum system for the single setup? I could use one.

I just need to know which line have to go where. I was told that I need a check valve or something else.

Budget change!! What clutch other than the a twin plate will hold 700hp?

I just ran into a problem with my charge pipe. It hits my oil cooler lines. Will braided lines with AN fittings work okay?

Awesome turbo!

Put some brake fluid in there while you're at it.

Manifolds with a little heat treated coating. I plan on picking up some ceramic coated ones sometime this year. This will have to do for now. The picture of the wastegate dump tub is hard to see but it is a very tight fit.

Man that is one nice and clean FD you have there. Nice to see other FD owners around Des Moines because I haven't seen one around since I got my car last summer.

I have been very bored. I just put all of the intake system back together this afternoon and man does it look GREAT!!!

I have Chris working on moving the neck on the radiator rite now. Then after I get that back I can put the rest together.

nrattV7 Do you have a black FD with aftermarket wheels? If so I saw you on the intersate last summer. Stix is has a black R1 which I hang out with a lot in the summer.

The pic of the black RX7 in my avatar is my car. If it was a black FD with 99 spec body parts and bronze FN01Rcs for wheels then that was my car.

Depending on how stripped down your setup is, you really don't need much.

run the vacuum lines from the oil metering injectors to either the compressor housing inlet or the air filter, along with one of the lines from the oil filler neck. I can show you pics of both options, just have to dig them up.

bov gets a boost source, as does the FPR.

Then just hook up the wg and boost controller as per the supplied directions, and you're good to go

Re: a clutch, if you have the funds I've been pretty impressed with the Exedy twin disc.....If you want a less expensive route you can go with either a spec or act sprung 6 puck. I run the spec, they offer a lightened pressure plate option as well.

Looks great! I thought about getting my manifolds done in black but opted with the polished look. I really like them in black though. Looks sharp. If you painted the irons it would look perfect.

You can use stainless lines with AN fittings. I have a 2nd gen oil cooler w/ mazdatrix AN adapters. You might be able to run to the local hydraulic shop though and pick up a set for cheaper. I had the hydraulic shop make up some for me. Kind of spend and if I had to do it again I would run with Stainless line. You can also get a couple shields that slip around the line if you are concerned about rubbing.

I really like the placement of the WG, do you think that there will be any adverse effects with it being so close to the DP?

Finally, Nice SE.

check valve is for the oil blow by. Seperate issue.

on a side note i'd recommend pulling out the vacuum brass inserts from the manifold your not using then drilling and tapping with allen set screws.

I did that and really love it. I played the vacuum cap game and hoses with screws look ugly. The ones on the side of the lim do nothing so they can also be removed for cosmetic reasons if you wish as they are just pass-thru.

Looks like it's finally comming together.

Nice, I went with a GT4202 1.33 T4 because the T6 isn't going to be able to fit with my v-mount setup, lol. Nice looking setup though.
