PorSTi Project Thread…, Well that was fun, time to make some upgrades! Options

[Amenson]

Banged out some big projects this weekend.

Rerouted the header around the new trans and DOJ's. The exhaust get's a bit close to the boot on the passenger side, special measures will need to be taken to keep it alive.


Welding is so much fun with no gaps, some of the joints were so tight I was able to fusion weld them (no filler)!



Also hacked the post turbo exhaust to the bare minimum and installed a v-band joint...



...so the rest of it can be done in aluminum. Simplify and add lightness.



Next on the list were the pesky silicon/clamp joints on the IC plumbing.



Gone...took a lot of cutting.



Also made clearance for the clutch fork.



Ran out of argon after tacking the IC tubing so I had to use the mig. Man do I hate grinding welds.

Total package, see if you can pick out all of the other little modifications.



Cheers,
Scott

Do you know what your pre &/or post intercooler air temps are ??

Do you know what your pre &/or post intercooler air temps are ??

Generally at standstill it heat soaks quite a bit but cools down quickly while moving. I have considered installing the stock STI IC water sprayer, which Subaru probably installed for this exact reason.

I found a few data logs on my work laptop and the highest Intake Temp was 47C although I think that I have some other data with higher values.

It turns out that the axles I had made are too short. During testing tonight I pulled the DOJ apart.

I need to have another set made but am out of 911 axles. If anybody has a pair that they would be willing to ship ASAP to Dutchman Motorsports I could use a logistical miracle in order to make Power Tour this weekend.

Send me a PM if you have something.

Why not machine some spacers and run loger bolts? How much shorter are we talking??

I am not sure how much length I really need but spacers are a great idea. Not sure why I did not think of that, I was looking at these when I ordered my CV Boots.


Spacers

They even come with longer bolts!

Probably not good enough for full power but might allow me to limp trough the event.

Thanks!!!!

Still looking for axles to modify.

Those are actually pretty cool! Gonna save that link for later...

[Mike Bellis]

I run one of these spacers on my 6 speed. I implanted magnets to use with my speed sensor.

All right, Bruce (BDStone) is coming through with a set of axles and beyond excellent customer service to get them to Dutchman Motorsports tomorrow. (IMG:style_emoticons/default/pray.gif)
Dutchman has agreed to make them a priority in the shop when they arrive and seem to be able to turn them around in a day. Then it is a simple overnight Saturday delivery to me and I am back in business.

The plan for the axles is to make them as long as possible so that they don't bind when level. It will require dropping the back of the control arm to install them but, I am not going through this BS again.

I have done a ton of stuff since my last post, some of it I am particularly proud of and some of it might be useful to others. Will make an update after Power Tour...and probably have a garage sale to pay for the expedited shipping. (IMG:style_emoticons/default/icon8.gif)

Hi Scott,

I just signed up on this board to tell you that I think your car is amazing!

I saw it at Parkland College, in Champaign, IL during the Power Tour. Your car caught me as soon as I saw the license plate and of course the STi badging. I have a "lightly modded, never tracked...ah.. who am i kidding....(IMG:style_emoticons/default/shades.gif) 2005 Subaru WRX STi so it was I thought it was really neat and liked the attention to detail. I was hoping to tell you this in person but I decided to move on to check out the rest of the 4000+ cars before the storms rolled in.

Very cool car man!

(I hope you don't mind me posting/sharing a few pictures I snapped of it with my buddies. If so, let me know and i'll take them down. I'll post them here first)

Very nice!

Hello there Mr. Snail. The old Familiar
(IMG:http://www.914world.com/bbs2/uploads_offsite/s17.postimg.org-18820-1433817087.2.jpg)

Very Clean and well done!
(IMG:http://www.914world.com/bbs2/uploads_offsite/s17.postimg.org-18820-1433817087.3.jpg)

Just to show you my car during heavy braking in autocross.

You probably won't see this until after the Power Tour so I hope everything went well, and you made it safely home.

Thanks for bringing the car out, it was awesome!

^Eric, great action shot of the Subaru braking hard!


As for the 914, I love those wheels in that color, not too dark or glossy!

Very inspirational build, I must stop viewing it,,,,hahaha

[Amenson]

Hi Eric,
Thank you for the very kind words and even more than that, making the effort to find the car on the internets and then signing up to the forum to share them. Now that you are here you should check out the other awesome Suby builds and start planning your own, you already have the same engine donor car that I started with. (IMG:style_emoticons/default/idea.gif)

Post all of the pictures that you want...especially the one of the rear. Dutchman Motorsports deserves some extra exposure for the job they did turning my axles around in a day. If you post it on Facebook, please tag them.

Thanks,
Scott

Glad you made the tour, uneventful I hope!! Car wise that is.

How is the hood opening doing for your temps, and is that the only opening you have for exit? Still at the point I am pondering the cooling, like everyone else does. But your system seems to work, and well I don't think you just drive around at idle in fear that it will over heat.

The hood opening is the only place air exits the radiator. Cooling is rock solid no matter what I do. Fans do not turn on unless I am stationary for a while even in super hot weather after beating on it. Most mornings on my 15 minute drive to work with several stop lights the fans don't turn all at all. The rather large Ron Davis radiator probably has something to do with it.

I've just finished reading 25 pages of a really well thought out and beautifully executed build. Damn!

Its hard to tell from the many pics you have posted so I will ask. How much room do you have between the Suby valve cover and the Porsche rear suspension console. (I suppose the threaded stud would be the first point of interference) In a few pics it looks really tight then in others it appears to be a few inches. Could you take a measurement for me?

Thanks for the very kind feedback.

There is a generous 3.5cm clearance between the valve cover and the suspension ear (IMG:style_emoticons/default/dry.gif).

Are you planning your own project?

Cheers,

I just looked and I joined this site 6 years ago. Wow. I guess I've had my '74 for that long. It hasn't moved, but I've been planning....and collecting parts. It needs a lot of love.

I have a line on a wrecked '05 Legacy GT with a manual trans for a good price. (Not quite an STI motor, but close) The clearance you've checked is one that has concerned me.

You have a few pics of Boxster hubs that you were using for your 5 lug conversion. Did you have any troubles with that? There is another thread here that suggests to mill the bearing retaining plate for clearance and it works. Did you have any other issues?

Thank you for the time you took to measure that for me. I hope to get at this soon.

The Boxster hubs do interfere with the stock bearing retainer. I used CFR aluminum bearing retainers and they fit perfectly. The axle bolt does require a step spacer as shown in the other thread. My lathe was not running so I used 3 stock washers, one of which was bored out to clear the little bit of stub axle that protrudes the hub. The 2nd additional washer was to space the castle nut to where it will interact with the cotter pin.

I don't think that I have a picture, I was in full thrash mode when assembling this area.

Thanks for the info Scott. This whole thread has given me the answers I need.

Now where are the burnout videos? :-)

Post of Last Year's Burnouts

This year was quite tame due to the clutch issue, only one on video and I have not seen it yet. I did one massive burnout because the entire level of the parking deck was wet from the guys power washing...only they got to enjoy it. I am not so sure they were so impressed after the show as I filled their work area with smoke. Overall I am glad that I had some restraint, there was not much life remaining in the clutch disk.
