Rarlyl8 930 Transformation

After dreaming of getting back into a 911 for many years, the opportunity came to act on the dream last summer (2010) when I found a beautiful 1989 2 previous owner 930 Cabriolet in Asheville, NC. The seller, a plastic surgeon, had owned the car for 18 years and bought it from a friend of his, another surgeon. He had all of the service records back to new, including original window sticker, original bill of sale, and the sales brochure for 89 911's. It had 70,000 easy miles and had any maintenance ever needed performed by professional Porsche technicians. The car was all original and the body and interior were in great condition. So we made a deal and it was mine. There were no surprises. However, I wasn't completely fulfilled as my dream car did not perform to my expectations and didn't sound like the car of my dreams. I got used to driving modern performance cars like ZO6's, modded WRX's, modded 335i's and the 930 was not quite in the same league. Sure, it was the hottest thing going in its day, but does not compare to today's technology.

I started roaming the various Porsche forums and more or less settled on this one and discovered a lot of positive comments about products designed by Brian Bodart of Rarlyl8 Motorsports. Lots of happy customers. Started talking with Brian almost a year ago and he asked a lot of question and recommended modifications that he felt would accomplish what I would be happy with. It then took almost a year to convince the "fun police" that this was not a bad thing to do. She will never believe it is a good thing. Anyway, Brian and I emailed and talked and decided without touching any of the engine internals and by using only bolt on mods, I could "transform" the car (to use Brian's words).

The plan was to use all Rarlyl8 designed components, his street muffler, intercooler, equal length headers, and newly designed heat exchangers, and the upgraded K27 turbo. Then all of the original components could be boxed up and the car could be returned to original if needed.

I trailered my car to Brian in Huntsville, Al, several weeks ago and left it with him, then picked it up this week. "Transformation" is an understatement. It is a totally different car in a good way. Scary fast! Turbo spool up is way quicker and the sound is fantastic. Before and after dynos indicated a gain of 114 hp and 87 ft/lb of torque. We were originally going to go with a 1 bar spring but this really proved unnecessary so the stock .8 bar spring is still in place.

Thanks Brian!!!!

That's the neat thing about these cars...they're fast, yes, but kinda ho-hum when left stock. Bolt on transformation is easy and makes one hell of a difference.

Once you settle in and get used to the current performance, the time will come when you ask yourself "what's next. I wonder what .2 more bar will do, or maybe different cams, perhaps play with the ignition, or???" There's a song that goes with this, Paul Simon's Slip Slidin' Away.

Dollars well spent. The question is will you be able to stop.

I think Brian has some good pics taken during install and completed work, but he is out of town this week. Maybe he will post some when he gets back.

Noise Level

I was PM'd about the noise level of the Rarlyl8 Street muffler and it has been discussed in other threads but here is my impression. It is fairly quiet at lower RPM. Nice moderate rumble, but definately neighborhood friendly unless you get on it and push it into boost. Then the sound comes alive. Not that loud, but but a beautiful sporty tone. Also, while cruising and not in boost, no drone. You can hear it but it is not loud or annoying. Hope this helps.

Very nice. Intercooler looks clean. Long neck or stock replacement?

Larry's 930 is a survivor in wonderful condition, all of the owners have taken great care of it. The mods we determined best for Larry's purpose were my headers, K27-7200, and my stock replacement intercooler. As Larry stated, pumping up the boost was not necessary as the power and driveability were so greatly enhanced. The engine is now under less stress than when stock while producing greater than 100WHP more than stock. Boost threshold was reduced by >1200rpm which vastly improved driveability. The torque curve became dead flat and did not drop below 325 ft/lb from 3000-6000rpm.
The only issue we had was the badly rusted header studs. Half of them snapped off requiring a very time consuming extraction. I have pictures of this that can be posted when I get back in town on Monday.
There is still power and performance left on the table as the fuel curve has not yet been optimized. We will take care of that next and expect the mileage to climb from 13mpg to 21mpg and add even more torque to the midrange.
For those who wish to turn a stock 930 into a really enjoyable machine these type mods are the ticket. All bolt on so the OEM parts can be stored to preserve the car's resale value. The fuel head remains stock and the Lambda system intact. Start up and warm up remain unchanged.
Also you might notice the orange SCAT tubing peeking out from under. Yes the mythical heat exchangers that I've been testing on my car have been installed on this one. The patterns are with the machine shop and god willing we will have heat this winter. Pelican will be notified when the first batch is final so we can all enjoy the nice cold dry air of winter... in comfort!

What is the cost of this sort of transformation? As described including installation at your location?

I quoted Larry 10 hours shop rate for everything. The broken studs cost us an extra 6 hours. I knocked off a couple hours due to the unexpected time taken for those broken studs.

Go to Brians website, //www.rarelyl8.com/, and add up the components you need. Brian says that it takes a typical Porsche mechanic about 16 hours to perform the work I had done. He does it quicker but has had a lot of practice. Since each car is different, it would vary some with each. For example, we did not anticipate the rusted studs which made the cost higher.
