I want to build Chevy conversion 928...Anyone have the conversion kit laying around?
 

I need a kit for chevy power conversion....if anyne has one I could borrow for a month that would be ideal.

After playing with a boat last weekend and hangin around the business end of a lobed up 502, I have to do this at least once in my life. Always wanted a hotrod and a '32 ford doesn't cut if for me.

PLEASE! :)

So you want to bastardize a Porsche??? Why not just buy a Vette and be happy for ever? I see plenty of Vette's around here, a dime a dozen, nothing special of a sports car! But to put a Chevy engine in a 928??? You are crazy!

What if you can't be happy with a Vette, or a Camaro, or a Mustang, or any of the other belly button cars. Maybe you want a power plant that has strong aftermarket following, but a body that is a little different, and has far superior suspension too boot. All the Porsche mills are very impressive for there H.P. per liter, for there time, but make mine an LS based GM engine. I'm not saying butcher up a clean, well maintained example. Those should be saved, and kept original, but what about the $1500 parts cars? The ones that would take more than $10,000 to make $5,000 driver? Yeah, while I'm day-dreaming, make mine 600H.P. NA 7.0 liter LSX with a 5sp. I'll upgrade the rest as it breaks.

If you had started this 3 years ago I would have donated a block and heads.

To be honest, have had two 928 for almost 10yrs now. One was bought as a parts car for the other, with chevy power from the start (the parts car). Both cars are auto, and I want a 5sp, and thanks to Mason, I have everything to change that now. I have both a LS 6.0 and an LT-1, torn on witch use. So I just slowly gather parts, and wait for the planets to Aline.

Try asking at this site, The Porsche Hybrids Board • Index page

You can turbo charge a 928 and get 600 Hp. I guess if you want to race you can do about anything. For the street, the stock engine is just fine. Ya, I can see a big block Chevy in a 928 with 671 blower sticking through the hood.....no I don't think so. Ugly and heavy like a Chevy!

There is a company in Las Vegas called Renegade Hybrids that has everything you need to make a conversion. Forget about the big block. Too much hack and cut. Go with a very reliable 400+ hp LS motor. Very streetable,easy to upgrade to more HP and looks sweet in the 928 engine bay.
If my supercharged 4.7 granades, that the route Im going. Have fun.

Believe it or not, its been done, saw pictures of it. Personally, I wouldn't,
the concept is unsettling. Not to denegrate Chevys (I own three, and my boat has one too). Just not a proponate of cross pollination.

A cast iron block alumnum head small block weighs less than a 928. An all aluminum big block would weigh less than a 928 lump.

Fred your Carl car would be great for the project <:

Yes I know of course about renegade....was hoping to manufacture some kits of my own maybe.

I read the same thing about the weight of the motors, and have been too the Renegade site and the Hybrids board many times day-dreaming. Turbos and superchargers are nice, but I'd rather have 400H.P. & 400ft of trq, normally aspirated, pump gas power, that I know intimately, and that I can tailor to my own needs because they sell almost anything for it. I just haven't decided witch kit from Renegade I would be happier with. When you get that kit done Mason, I just might be your first customer.

This is a popular discussion. The theory goes that the Chevy engines are cheap to buy & maintain, better HP and lots of aftermarket options. (prob true)

The problem is there are very few cars with sucessful transplants. The so called turnkey system (e.g. Renegade) seem to actually have spawned few successful transplants (i.e. finished) and many projects in progress.

By the time you are done there is a lot of work to fit and correctly mate up the engine, electrics, transmission, exhaust etc quite a lot of extra expense and custom work and so it ends up not being an easy install at all and probably not really cheaper than fixing a stock engine - at least not initially.

The idea of installing an American engine in a 928 makes me think of people that get sex changes. It gives me the creeps.

this forum needs a like button....

I love the 928, but ignoring the weaknesses of the engine doesn't make them go away, a SBC or my preference a Ford mod motor does.

OTOH when your done a lot of the Porsche personality is gone, and realistically the street and track options become more limited. On the street you are spinning wheels, and on the track you will be classed with insane unlimited racing cars.

ship of fools
 

Ahhh, a lively topic. First of all...IMHO..blasphemy, and you are going BEYOND the Bad idea range. Secondly, you are far too conventional. A domestic v8! Like that hasn't been done to death. Blah blah bow tie, blah blah ford...sorry...Booooring!

Get yourself out of the box and research the options. Sorry to say the renegade hybrid does not impress me. None of the conversion kits do. Find just One example of the conversion done correctly and work from there. I am talking a daily driver with AC that handles correctly. Bonus points for reasonable mileage and double bonus points if you can legitimately smog it in California. Next...troll fleabay and Clist for all the aborted conversion projects and save a bundle by picking up the pieces while pretending that they can go together. Understand that conversion Kits are usually a scam and few, if any actually bolt into turnkey systems.

Lastly, make sure your war chest is about 20k and be good with the idea that when you are done it will be worth....oh 4 to 5. no biggie.

Ya know...for the labor and parts...you could have a nice 32v together and running well.

Your cost basis is off if you're doing the work yourself.... and the value of the finished project doesn't really matter, to some of us at least.

cost and effect
 

well....., yea, you might be handy enough to get away with 8 to 12. That is what I usually see invested in the abandoned projects when they come up for sale.

It is just that the track record on the conversions is so abysmal, I caution against such a dubious undertaking. Should you rush in where this angel dares not tread...I reiterate...Find a good conversion (if one exists) and follow that example. Please be cautioned that anyone who wants to sell you a kit has a motive to "stretch the truth" a bit. "yea...Plug and play!" "sure...everything is there"

And again...you are in the ho..humm...heard it all before...seen it all before...put a detroit mill in your (insert car name here) category. I am also a Jag aficionado, therefore, the whole American V8 swap thing just bores me to tears. I have seen such swaps dozens of times and have seen it done correctly in a small fraction of the cases. As the resale value, i.e. the "worth" of the car decreases, the amount of work needed to make it not worth fixing also decreases and they tend to be tossed into boneyards or languish half functional in barns or garages.

Years ago, it actually made economic sense with a fairly new v12 that, as a result of a bank failure required many thousands of dollars worth of motor to be brought back. Since then the V12 has become a very cheap engine and (thankfully) the madness has almost left the Jaguar world.

Similarly, the Porsche v8s are now (relatively) cheap engines...IOW there is no logic to the decision. You don't GAIN anything, or perhaps there is some gain, but it is offset by increased cost, or obtainable through other, more viable options.

I further contend that for the time and money spent you could have a nice running 928 AND a nice running Camaro. Hec, throw in a few v6 Camaro and Firebird project cars as well.

In defense, I believe if you have the knowledge and machinery it can be dome for under 3k. I know i have done a 350 chevy conversion on an mg midget and a Jag xjs for a couple grand. Providing you have the knowledge of electrical, that is the big one.
