Street Build 1G Build: Return of the DSMer!

[Vegas Smith]

I need to install the turbine housing and take some pics, but it's the XR71-64S with 0.64 hotside.

Well were waiting on the updates, brother.

I bet that thing will be a blast on the street

Yeah, it's purely for street use. Most people would opt for the 0.82 housing but it lags about 400rpm and make more power around 8k according to Robert Young. When I dyno it I'm just going to tell them to hit 600 and stop there.

Wow, that's what I did and for the same reasons.
.63 A/R, on similar size turbo, and I said let's call Close Of Business at 8,000 rpm.
I also gave ER a "stop at hp" number for their dyno tuning sessions. Which they hit pretty easy.
I figured I didn't need the extra ~40 hp or so at the top end. But the extra ~400 rpm of bandwidth at the bottom end I sure did want.

First time I've stumbled across this post and "accidentally" read the whole thing. I just bought my first DSM (93 tsi) and while it wasn't quite the wreck yours was starting out, it was still a mess. yours is definitely an inspiration! love the build!

 

[Vegas Smith]

Sooo what’s in the Xona box

Thanks for taking a look. Huge updates coming as the new parts arrive.

Vegas I just gotta say man I think you’r a true dsm’er. You took a car that only a mother could love, and thru hard work and dedication turned it into truly a NICE car, I don’t know exactly what your ultimate dream or vision for your ride is, but I just wanna say I think you have a nice well rounded street car that you should be proud of, I know I would be, cheers brotha

Thanks my man. I've always loved these cars so there's nothing else I'd rather build.

 

[92AWDHX40]

Im with you man I love my dsm, even when things break.

Build or have one built right

Parts are back from Polydyne coating. It's pretty neat that Polydyne is only 13 minutes from me. Just a pleasant drive to pick them up. I'm doing some installing today to determine fan clearance to see if I need to switch anything up. Updates coming.

 

[92AWDHX40]

Sweet man no t3 yet but its coming for me, curiors to see how the coating holds up, looks so good, updates when you can following.

 

[We're on Boost]

Thanks for the really good pics, wow! Are those cell phone pics, or other camera type?
Even with a good look at the O2 housing here, I'm still guessing at what the extra fitting is for - the one that has like ribs on the outside.
Coating looks real nice. And the way FP finishes center section, it's almost too nice to put on a car. I would just leave it on my coffee table in the living room for a while. The compressor housing flange surface and printing on it, wow too.

These photos were taken with an iPhone 11. The cameras on these phones are incredible. The o2 housing has two bungs for wideband sensors and the big ribbed fitting is for the TIAL wastegate; it's a recirculated housing.

 

[We're on Boost]

Yeah, I've probably said it before but I wish all the pics older than about 2-3 years ago could be retaken with modern cameras.
So the 2 sensor bungs on the O2 housing, one ribbed and one not - are the ribs for cooling? I mean, if that's what they are supposed to do, you could put a wide band in that one because wideband sensors like to run a little cooler than a regular narrow band, right? You could put the stock OEM narrow band in the one with no ribs.
This would be handy for anybody who hasn't already added a wideband bung onto their downpipe. Which is what I did because I didn't want to do narrow band simulation with the wideband. I wanted both sensors.
Or is it for some other reason?

Correct. The ribbed bung is for extra cooling with a wideband sensor.

Amazing build thread. Awesome pictures, much humor and no bashing = the best, long, thorough thread I've come across here, and I have read many. From an 18g, to another, to another, etc turbo. Man, I wish I had the money to do that. You say you hate the job, but I love mine and am always broke, . You have a great car and your work has become a value to us all.

Thanks man. I moved on from that job a long time ago and am much happier.

Ok, there we go with 2 good sized fans on the front and a fair amount of space aft of the radiator.
Spal VA10-AP50/C-25S - 12 inch pusher fans.
I like it that Spal has nice dimensioned drawings for these fans. You can figure out the fit, go or no-go, just from their drawings pretty much.
You could probably fit a 12 inch puller fan on the back side passenger side of the radiator? If you needed it.

Yeah, SPAL fans are such high quality and you have so many options. It's a TIGHT fit, and I had to trim some of the ribs of the fans but you gotta do what you gotta do. This is all a final form project. In other words, I don't plan on changing this setup unless things don't work they way I want.

 

[92AWDHX40]

Nice man im running 1 spal fan for now, it all looks amazing man, following all your posts, and thanks for the help, and cams man.

It is looking great. Are you back to driving it yet or still buttoning up?

Still putting it back together. With a 1yo it has been hard to find consistent time to work on it.
