My first Audi - 2001.5 S4 with Custom Single Turbo setup...

This is not Audi any more!

haha I am just messing around. Lee is not putting an ls in lol

I knew this wasn't happening.........if that was the plan and I were him I'd just buy another chasis(non-Audi) to dump that in. Would be so much easier in other proven LS swapped platforms.

[Monty23]

Not yet at least

[bobkatkat]

Whoooo HOoooo 100 page thread for Lee!!!

[spd579]

Only motor swap I'd be cool with would ba a RS6 motor or a lambo v10 in the name of OEMitility

100 pages and half a million views? Damn. Crazy.

Sorry no updates lately... just know I'm working on some pretty neat things...
I did get the heads for the 2014 build machined and then cleaned post machining...

100 pages, 5 motors and half a million views? Damn. Crazy.

They look good, but the opening to the Intake ports needs some work to correctly match the gasket / RS4 intake opening.

Like so:

Ahhhh......I need to do that. I'm taking the heads back anyway for some additional machining because some of the valves dont look to sit completely flush against the head. The valve faces should sit flush correct?

Yes. And the combustion chamber volumes should be as close to the same as possible. You can be pretty sure if some of the valves are not seating completely, the chamber volumes are going to be all over the map...

I was also thinking that as well.....

The valve faces should never sit totally flush with the chamber as you have the thickness of the valve. Usually you'll have around 1mm of valve sticking up from the valve seat.
Are you maybe seeing the middle intake valve looking like it sit's at a different height because of the angle of those valves? I can take a pic of a stock head if you'd like.

I have a spare stock head I'm taking up to the machine shop with me when I return them. I apprecaite it though. Go ahead and post a pic for info though if you have one.

Hey Lee,

Did you get a chance to post my throttle body by any chance?

[britishturbo]

Should be on it's way to you mate.

Compression was down to 70psi in that cylinder, and she was smoking like a pig :-)

I dont get it?? cool piston graphix makes you loose compression? I had some flames patterns put in my ceramic tops.....I guess lightning bolt designs are no good???

Haha indeed. If it was just a graphic that would be cool.. but as it's a crack through the piston it's not quite as neat ;-)

[britishturbo]

So i don't think I ever shared this picture...
This is what I found when I pulled my heads off the day after running 10s in the car... this was why it was missing at the track in 4th gear...
Silly stock RS4 pistons...

holy shit..... just had a flashback to my childhood of those "this is your brain on drugs" anti-drug commercials..... kudos to you for generating enough power to kill a forged RS4 piston so completely! You should save that thing to use as an Easter egg for your kids lol

I'm still surprised that piston stayed together...

Yepp. I'm going to pull it from the block tomorrow and see if I end up with 2 pieces ;-)

[Lupe-81]

Poor stock RS4 piston. It didn't stay in one piece in 1,7s FATS engine. BF block still intact?

[spd579]

I'd be willing to bet the wrist pin is what's holding it together

I got $5 on the cylinder walls/piston rings

your right, especially with the crack's orientation

you have any updates on your build?

Just dropped the heads back off at the machine shop to get all the valves seated evenly and finish porting the intake side to be flush with my RS4 IM. I was going to use some RS4 main caps but the machine shop said there would be a good bit more work involved to use them and since I've never seen a S$ min cap break I'm just going to use the ones that came with the block and it should be getting align bored within the next week. After that just assemblly. Have to get the motor in the car with the turbo and firewall removed to mach up the down pipe and intercooler piping......after that just fuel lines, vaccum lines, odds and ends and then figure out who's going to tune it for me. Hoping I might be able to convince BT

Hoping to have it running by late spring, possibily earlier.

no surprise here...stock shit is weak....what did you expect to happen?

You really should start keeping the pieces in display cases. Kind of like a prized Baseball.

Maybe I'll make a display out of this one... the aftermath of 10 seconds on a 2.7...

Cool, be sure to post up more fab pictures! You get your efr yet?

Not yet, it's the next thing on my order list. Holding out until I get the motor together.
