I have seen everything from Wankel's to LS1's inserted into donor 911′s, RX7's etc etc etc. This whole **** about a Ford with a Chevy engine , or a Porsche with a whatever motor to me is ridiculous . It’s metal, plastic and rubber , has moving parts and burns gas. It runs...... It’s a machine……. use it.

 

Listening intently........

 

As I was the first to swap in a 5.3 into a 944 and design my own parts along the way,I will be grafting another one into the 928 and designing the parts as well. The 5.3 with a Z06 cam and LS6 intake puts it at LS1 power at half or less the cost.

 

What measurement?
I've got an 84 G28-07 with a torque tube installed on the front of it.
Its sitting on garage floor.

 

Sounds good........seems like I read something similar over on NoRotors.com about using the Z06 cam and LS6 intake with the 5.3, but it's been a while. I went down the built Cobra 302/T56 Viper swap for my RX7.

Swap arguments, IN ANY platform, tend to baffle me. To me, if the LS9 (LS3 variant basically) is good enough to best the Veyron's quad turbo in the Hennessey Venom for top speed, then a "Chebby" engine should be good enough to shoe horn between the shock towers in a 928.......If it was good enough for Carol Shelby to do with a Ford 260 in an AC Ace then it should be good enough for just about anybody. "One man's treasure, is another man's trash" is what it really boils down to.

Yes, you say, he is new to this forum......but this is certainly not my first rodeo, as I have turned wrenches and fab'd my own parts on everything from Detroit Muscle Cars to Alfa GTV-6's, VW's (air and water), Built Spec E30 BMW's to campaign in NASA events to owning and modding 4th gen Supra's as well as taking part in rotisserie frame-off restorations as well as my own engine swaps.......In the end it's just all about perspective. I will say this however about a swap.....I do believe in retaining the parts and the integrity of the car. So that at some point, I could return it to it's factory condition if I so chose, instead of hacking it up. Honestly, some of the SB Chevy 350's with a carb'd air cleaner hole cut in the hood with a sawzall makes my eyes water a bit lol.

 

I have an '85 that is more or less a rolling chassis. If I were to do the LS swap, is there a market yet for t-tops, 8 ball gear shifters, or a horn pad with a bowtie? I would like to have a more authentic feeling conversion. In all seriousness, I do understand the temptation to do these conversions with 80s P cars. I'm like Speedtoys, I guess. I just wouldn't have the stomach to do the Chevy conversion. You could do the same thing to a Lamborghini Diablo and get more *bang for the buck* I guess. Now that's an expression I never thought I'd use when discussing 928s. I thought that expression was specifically reserved for rice burners and pony car boys. I guess it's all in where we find value. To each their own.

On the Lambo point.. It might make more financial sense to actually buy an 80s Pontiac Fiero/Lambo kit car to drop the ZR1 motor in or whatever than to actually do it to a *real* Lambo, right?

 

Funny thing is that nobody has ever asked me to open the hood on the 94 to have a look. If I could only keep my big mouth shut, nobody would even know whats going to be under the hood of the 80. T

 

77Tony, I have been following the 6spd transmission swap and your posts over on the Piranha thread.....very cool and I can't wait to see it at a meet at some point.

 

@Kiln_red lol Nice dig.....Touche'

 

Landseer, we need to confirm the measurement of the Shaft tip to Torque tube/ Bellhousing flange distance when it is all bolted up CORRECTLY at the rear trans coupler and front shaft coupler.
Take a picture if you can.

To clarify I'm only calculating the adapter dims for the New LS series engines. For those in the know there is a 0.400" difference in FW depth from old SBC/LT1

 

With a 6 speed Corvette tranny swap, and 4.10 or 3.73 final drive, you won't need an LS1 to make the 928 fast, sure it won't have much of a top end anymore, but it'll be a stoplight racer like so many people want it to be. Is a Corvette tranny swap the same butchery as an LSx swap? Some would say it is, but i wouldn't. The stock gears/synchro's and shifter design is not that good anyways, so i say the Corvette tranny is an improvement over stock, whereas to me an LSx is not really an improvement over a stock 928 motor. Why would you replace a rare engine with a common as dirt GM motor? It'd be cooler if you put a Ford 5.4 Lightning/GT motor in it, much cooler if it was an actual Ford GT motor, since those came dry sumped from the factory, just like everyone here wants with a 928 motor, that itself would be an improvement over the stock 928 motor, but a GM 350 motor? No.

In fact, a Ford GT 5.4L would be an ideal swap into a 928 for uniqueness and power capacity. Taken from Wikipedia "The Ford GT version of the 5.4 L is a highly-specialized version of the Modular engine. It is an all-aluminum, dry-sump 5.4 L 4-valve DOHC with a Lysholm screw-type supercharger and showcases numerous technological features, such as dual fuel injectors per cylinder and oil squirters for the piston skirts, not found in other Ford Modular engines of the time. The GT 5.4 L benefits from an improved version of the high-flow 2000 Cobra R cylinder head and unique high-lift camshafts. The GT is rated at 550 hp (410 kW) and 500 lb·ft (678 N·m)."

To me having that in my 928 would be equal in cool factor to having the stock 5L 928 motor, and it would be an improvement. It probably costs twice as much as a new 928 motor does, but that's the price of being unique.

 

I am not going into what is wrong or right...what appeases the spirit of Dr. Porsche.

I just want to know if anyone on here has done one. If so, how did it go?

 

Yee gods! do we really need another thread on this - quit already.

The only info I'm hunting for is where do the Fuel pump and ignition tie into with a standalone GM harness? The rest is a cakewalk.

 

if you follow the diagrams the stock ign and FP should follow the same as the GM. most chevy installs i have done (race cars, hot rods, and 4x4's) use the stock harness and we just added the ign and fp power where the stock one went.
