JBones's Silver Bullet B6 S4

Hey David, that sucks man! I wish you luck with finding a nice D3 S8. Those are really nice cars. I had a purple one that I worked on at Alexandria and it was one of my favorite cars whenever he brought it in.

Thanks. I have not installed the brakes yet. I still need to finish up my engine work so I am working on that. I didn’t want the brake rotors to sit outside in the rain and rust while I am working on the rest of the car so the brakes are the last thing to go back on before I drive the car again. Don’t have any new track times. Need to finish everything else first and then break in the new parts. This Fall I should have some faster times though.

6th gear is always going to be slower than 5th gear but it feels like I am coasting rather than still accelerating.

I know that most road course videos put some people here to sleep but I will see if I can put together a good one from my last time at VIR.

What kind of speed do you think you would hit in the 1/2 mi?

Why you switch headers?

Got some more work done on the S4.

I took the front end of the car apart. Here is a shot with the front bumper off.

Got the core support off.

Took all the supercharger brackets off.

Took the alternator off and disconnected everything from the engine, transmission, and front subframe.

Removed the transmission crossmember and installed my engine support bar to hold the engine, transmission, and front subframe in place.

This next step is the scariest few moments of this repair. I removed the front subframe so the only thing holding the engine and transmission in place is the engine support bar on top. That is a lot of heavy and very expensive parts hanging in the air while we get the drivetrain table in place.

We got the engine and transmission on the drivetrain table and raised the body of the car up out of the way.

This is what the engine compartment of the S4 looks like with the front end, engine, transmission, supercharger, and a bunch of other stuff taken out.

Here is a side view of the engine and transmission on the drivetrain table. Look at the pretty long tube headers!

This I lowered the car back down and covered everything up so that the rain stays off my parts.

That seems to be the new “it” thing to do…everyone who had the old headers want to switch to the new version (…and that’s fine by me since you will finally see 2nd-hand sets available, just not up for long)

Honestly, it’s not a bad move for those who had the V1 headers. The new ones are much cheaper, so you can sell the old ones for about 70-90% the price of the new ones.

Lookin awesome Jimmy.

But you have to pull the engine

What’s the point? I don’t get it.

I spoke to Jimmy last week and we discussed this. I believe the design of revised headers work much better with FI. The original V1 headers are optimal for NA S4’s. I don’t know enough about it to answer in-depth, but I’m sure someone else will chime in with more details.

Yeah that’s super impressive!

thats pretty sweet. is that an mobile lift? looks like its not really bolted into the ground.

Thanks guys.

It can be a mobile lift if I get the casters for it. The lift is totally free standing and it doesn’t need to be bolted down. It is a really neat lift. The company sells a lot of attachments for the lift like a sliding middle platform, a hydraulic jack platform that goes in the middle of the lift, a crane attachment that can be used to pull engines.

thats ideal, a modular lift. I must have missed it, but what service are you doing to your s4?

The V1 headers are better for torque whereas the V2 headers are better for power. Seems like the V1’s make more sense for DD’ing but if you’re at the track the V2’s is what you want to have.

I think Jimmy honestly just likes to take things apart and put them back together…haha

Honestly though I think he has built JHM heads laying around…or fixing his leaking valve stems maybe.

I have lift envy, I’d really like to put on in my new house, but it will probably be a few years before I get around to that. I really like those Ranger quick jacks right now, I’ll probably pick up a set of those this year sometime.

just put it in the backyard :slight_smile:

Mec, there is a few things that I am doing but the big ones are replacing the cylinder heads with JHM rebuild cylinder heads, doing a timing chain service, installing the new version 2 mid-length headers, and reinstalling the stock sixth gear set in the transmission. Euro is right that I have leaking valve stem seals. Then the engine has 104K miles and it has never had a timing chain service plus that stuff has to be opened up to replace the heads anyways. I got the version 2 mid-length headers too since I was taking everything else out. The old version 1 longtube headers are already sold so that helps. Finally I have run into a few instances where I need the stock sixth gear set in the transmission like driving through the mountains and on certain road courses like VIR. I hit like 150 mph in fifth gear while going up the back straightaway long before I crested the hill at VIR and then shifted into sixth gear which doesn’t go much faster. With the stock sixth gear set I bet that I can hit 7K rpms in sixth gear which puts me around 175 mph.

Euro, there is always a plan when I take stuff apart. I can’t afford to just take stuff apart for the fun of it when I have so many people that want me to work on their cars locally.

A lift is such a nice investment! I wish mine was inside so that I could work on stuff year round and regardless of the weather. One day I will add on to this house and make a spot for two lifts but that is a few years and hundred thousands of dollars away.

I might be interested in that 6th gear if you want to sell it.
