My ongoing project car

[N.RotaryTech]

Haven't really yet driven this car to get a feel for its power & torque, I don't really expect much since its a mild ported S4 NA.

I did get the oil leak fixed, kind of, its still leaking a little where the other plug is in the oil filter pedestal. Probably just needs some sealant.

Updated Engine picture.


And how its going to look for now until the next cosmetic change.

I made a hood scoop block off plate. Its a little rough. I'm not using the scoop anyway, and this should keep most of the rain out.

Engine specs.
As of now. Nothing really special.
Its basically an S4 NA. 9.4 comp rotors, S4 intake manifolds.
Apex seals are RA Classics. Also has FD corner seal springs.
Porting: End plates have been street ported. Mild?
Housings have had the NA diffusers grinded out. And ports have been mildly ported.
Exhaust has RB mufflers and pre-silencer.
Clutch is a Clutch Masters stage 2.
Air filter is an Advanced Auto Parts store bought cone style.
Radiator is a no-name brand from an online discount parts store.
Lawn mower battery from walmart.

It still has all the original S5 electronics.

It has had the following components removed for various reasons.
Emissions equip. Rats nest, air pump, etc.
All the AC components.
Power steering pump. And bracket.
2ndary throttle plates.
Aux port sleeves and actuating rods.
And a bunch of other misc. parts from the engine bay. Like sub-zero start tank, washer fluid tank, etc, etc.

So the 7 has been down for upgrades since 10 days ago, I'm not going to post about it yet as not to jinx it.
But I will show a little something on the side from the main project.
This:




I decided to try out Fiberglass work for the first time, and repair an old under-tray.
The works a little messy, but I can handle it.
And I know it looks like crap.
I followed the directions from the can, and used about 4 squares of fiberglass.

That's it for now.

If it works, it works.

Not like anyone sees it.

I say good job.

[N.RotaryTech]

Well after a month of working on it, I got it started last night, and took it for a drive at noon today.
I still have a few bugs to work out, like an exhaust leak an such.

That's it for now.

[N.RotaryTech]

Alrighty, I'm so excited about this.
Here's what I've done,
Last year sometime I acquired a Turbo setup for cheap. Turbo, manifold, downpipe, intercooler, and some elbows, included.
I finally got to doing the project a month ago.
Finished it a few days ago.

Pictures and details coming very soon.


I am taking it to DGRR and the Mitty.
I think from where I'm coming from, when I get back home, Ill have around 1000 extra miles on it.
This is going to be one heck of a break-in. lol.

Ok, continuing what my previous post says about this turbo set up, let me get the pictures & details rolling.

Some picture sets might not be clear of the progression of things, I was more concentrating on building this project, but I think you'll get it.

First the turbo setup I acquired.

(Post downpipe modification.)

I started modifying the down pipe cause it was too long as to fit in between my RB silencer and the turbo.



As i took off the RB silencer the studs got fubared.

I ended up shortening the totally stripped stud, and cut away a thread or two of the other stud, cause the fastener I used was hanging up.

This is what it looks like now.

I took it to a local car repair service center to get it welded together.
Added the extra O2 sensor bung later.

Future plan for this downpipe is to sand it down and cover it with hi-temp paint.

Next, I fabricated the intercooler mounting.




I didn't even have to move the overflow tank or the horn. I did reroute the coolant tubing though.


I painted it black.

[N.RotaryTech]

Changing the fittings on the turbo.



This is what i used for the oil feed line for the turbo. Parts from the plumbing section at Lowes. They are for Faucets.


Here I fabricated some heat shielding for the turbo.

[N.RotaryTech]

Intercooler piping. I used exhaust tubing from o'reilly auto parts.


Painted.


I modified an intake pipe from a Subaru Impreza and used it for the intake pipe for the turbo. I cut a lot of things off of it to fit and used epoxy to fill the holes and seams.



I cut apart my old cone air filter to make a filter element for the MAF sensor. A normal size filter wouldn't fit in the engine bay.



I installed 750cc injectors in the secondary's and rewired the connectors from S5 to S4.


Parts, gaskets, etc.

And boost gauge, with a switch for the gauge light.

Any concern with those oil hoses not being made to withstand petroleum/heat?

[N.RotaryTech]

I figured they handle some heat & pressure from what they're originally designed for.
I don't know how it will handle oil though.

I'm definitely putting its durability to the test.

[djmtsu]

I'm wondering if that oil feed line is TOO big for the turbo.

You might be feeding it too much oil, thus making the turbo smoke. You know the stock turbo line has a restriction pill, and many aftermarket turbos also require some kind of restriction.

Just a thought.
