ATP Wastegate Swingvalve?

[rockslinger]

Here is a list, special notes will follow at the bottom of this post. . . . "ZF" plastic pump with all mounting hardware and hoses, some sort of heat shield to go on the back of the plastic pump to protect it from exhaust heat. You will need to make studs and use exhaust mani nuts to hold the s/v onto your turbo, you will also need a adjustable wg arm. Ok so there is the list. as far as the mounting hardware goes, the masi uses the same ZF pump and does not use the back bracket that goes from the pump to block. I started out using it, but last night I took it off and it seamed to work just fine without it. I made my own heat shield by trimming down a heat shield that I found on a firewall of a turbo chrysler, the back of the pump already has mounting holes for the heat shield. I used two washers as spacers to go between the pump and shield. You will need some sort of a porting tool (a dremmel will probably work) to shave off some material on the outside of the sv so you can get the nuts on and off. The only nuts I found that work with a socket are exhaust mani nuts. I will be posting up a build thread on how to do this in the next little bit. I have all the pics needed I just need to get the time to sit down and write it out. It will be first posted in a staff section for the all the gear heads to see and make corrections, then out to everyone.

Ok so I posted up a official atp build thread in the FAQ area.

Awesome man! good instructions. Only thing I want to know is where do I get this "ZF" power steering pump?

[rockslinger]

Oops. Forgot that part. sorry about that. I'll post that up in the build thread. I got mine out of a 92 shadow. Its pretty hit and miss on what has them. you look under the hood on two different cars of the same year and one will have it and the other won't. My understanding is that they came in 89 and newer cars. So just head to the JY and start popping hoods on all the 4 cylinders till ya find one

Great info. Well done!!

Thanks

You should probably add some info on building a downpipe with a flex pipe and how it fits when completed for reference. Another question. Will the power steering hoses from the ham can style power steering pump bolt up to the ZF(plastic) power steering pump? (looking at your thread it doesn't look like it). Another question - what are expected benefits of this (anyone translate this into increased HP, full boost at x amount less RPM and or better 1/4 mile times?) Great thread otherwise.

HE DOES : 4.5" radius pipe. If you're that helpless to figure out the rest with just pics then have a shop do it.

If it doesn't look like it and the pump is so completely differently shaped then common sense would say you grab the lines with the pump

Boost response is incredibly quick. Rockslingers mostly stock 2.5 will have the T2 turbo start producing boost under 2grand, and full boost by less than 2500rpms. That's VNT and Mitsu territory.

Oooh feisty today aren't we?

Also full boost at 2500 rpms confirms that I WILL be doing this lol!

he's always fiesty. The ATP is something we needed years ago, good price too for what you get.

So if you look at the list I made at the top of the post you will see that it calls out for the ZF pump with all the mounting hardware and hoses. . . that means that the hoses that are used originally with the zf pump will be needed when using the zf pump for your aplication. It also means that the mounting hardware originally used with the zf pump will be needed in your application as well. As far as the down pipe goes, with any vband style flange in turbo or non turbo applications you will need a flex joint. If your looking into doing this, you should have already found this out by either looking at the pics in my build thread and thinking, "man for some reason that exhaust doesn't look like my doughnut style, Maybe I should look into a vband style down pipe that will go with my vband swingvalve", or by looking at the pics posted earlier in this thread and thinking the same thing. You get a 3" vband flange, attach a 3" pipe to it that has a 4.5" radius bend in it, put a o2 bung in there somewhere down the line from the turbo so as not to melt your o2 sensor, and also put a flex joint in it. Put the flex joint before the o2 or after, I'm sure it doesn't matter.

Man I can't wait to do this same thing!

[rockslinger]

The thing spools real real quick. Now I went from stock exhaust minus a cat with a tu 2.5 swing valve to this with a full 3". I start boosting at about 1600-1700 rpm and get full 20 psi at 2400-2500 rpm.

[rockslinger]

I would not go with the obx setup though. Too tight of a bend I think

[DetroitTurbo]

Now is your 4.5" radius down pipe custom made or did you buy it from somewhere?
