Glad to have a V8

[emcon5]

Well, my 911 is parked for the forseeable future, my somewhat ugly oil consumption problem (~1 qt/300 miles) got REALLY ugly last week, jumping to a 1/2 quart in 40 miles. The car is out to pasture while I figure out just what I want to do, and come up with the funding to do it. It seemed like the ideal time to dig up this thread.

I'm nearing completion of my v8 sbc in a 66 912. Edlebrock
aluminum heads, holley street avenger, comp cam, edlebrock
intake, etc. 915 trans with centerforce dual clutch, Ron Davis
racing radiator, upgraded 75 911 suspension and 930 flares.
I also have a 76 911S. If I hadn't come along and rescued
this old 912 it would end up in the junk yard. Sure, I 'd love
to install a high performance 930 motor in a 911, but since
I don't have 20-30 grand I'll settle for this route cause
I want a very very fast Porsche to humilitate these ricers
and boy are they getting on my nerves. I don't think anyone
disputes the fact that a 911 motor is superior to a v8. It's
simply a cost alternative and nothing else.
For those interested in this kind of conversion an LT-1 will
not work in a 911, however they will install in a 944, 928. It
has to do with the water jackets in the front of the block.
Anyone with knowledge on the possibility of installing a 928
motor in a 911 please let us know. To KS911, Keith thanks
for your technical advice and all the pics you sent me. I
appreciate it. Too bad some people on this subject don't
fully appreciate your technical ability.

I'd be interested in this info as well but instead of a 911, put a 928 motor into a 914 for a sweet little midengine pure-porsche V8 car.

Check the 914 board. There is a guy doing a 914 with a 928 motor - he is really busy so his progress is slow but he has posted pics. Also, a company in Germany sells some converted cars - both 16 and 32 valve 928 motors in 914s. There were some pics posted a while back of those cars.

I have looked into the renagade kit. It comes out about the same price as a 3.6 swap. I don't see how it is any cheaper. The engine may be a cheaper but by the time you buy everything else to do it right, it's a wash. The savings would come in HP upgrades, as the 911 3.6 costs far more to "hop up".
I don't condem the V8 swap. I am considering both(3.6 and V8). I just don't see the savings VS. all the extra work to do it right.

Lighten up on ks911. People have done worse things to Porsches. Take the 996 for example.

Here is a rundown on the cost of a v8 conversion.

Custom radiator (Ron Davis) includes twin electric fan with
all associated sheetmetal
$1100.00
This kit, available from Renegade Hybrids
is of very high quality!

Adapter kit $1700

High Performance clutch kit Centerforce Dual $750


Then figure in the cost of a V8

The conversion if done by yourself could be performed in
roughly 40 hrs.

OH MY GOD.............................HOW LONG HAS THIS BEEN GOING......................LET IT GO PEOPLE...LET IT GO...........



flat 6 whine baby...... flat 6 whine

[jess p]

I doubt I'll be able to hear the whine of the flat 6 as I pass
you. Being as a v8 400 HP has such a deep exhaust note!

Parts I can buy on Sunday from a local parts place.

Say it with me:

I thought i should add my name to this thread, after reading every page today i think it is only prudent to do so.
I can see many points made here, some technical ,some emotional. there will never be a solution that would make everyone happy.
I am sure that the V8 has served its purpose for ks911. he seems very happy with his conversion. i am happy for him, he has found what he wants in his car, other people are really happy restoring a porsche 911 to its former glory and have found what they want. others transplant larger or newer engines into their cars and get what they want. hell i still want a 911 even after reading these forums for a long time, but for now i will have to contend with my friends cars as well as my fathers 996.

Dammit, I have to add to this crumbling pile of crap post.

If we need a Cayenne forum for all the whinerers who don't like it because Porsche should have stopped mechanical and aesthetic development with the '73RS and just kept making those for less than $12,000, maybe there should be a chevvy V8 conversion forum if the idea is so bloody good. Then this post could be moved there (no doubt in solitary confinement).

There I said it.

[Rich Brennick]

I, too enjoy the fan whine of a flat six, but I also enjoy the sound of a Pete Jackson "noisy" cam gear drive set right next to my ear in my 914 with a 283 7000RPM plus engine.
Yep, parts on Sunday is good, too; but I haven't needed any.

I bet the Brits wanted to fry Carrol Shelby when he went to help a small company called "A.C." get in the game.

Very enjoyable reading so far.

It's snowing in Michigan!

Perhaps you should have stayed away from assuming that any of my buddies are opinionated.

So, is this thread the winner of the longest-running, most-posts and most-views in the history of the Pelican BBS?


It just keeps going, and going, and going....

[Brad Roberts]

Chris,

I drove the 500hp V8 911 customer car this evening (while tuning the injection system)

Its crazy.

That car scared me just sitting still inside the shop.

[Brad Roberts]

Romp on the loud pedal and it seperates the men from the boys real quick.

I set the rev limiter at 7200.

The early chassis (72) is really really light. I had NO idea they where that much lighter than a SC chassis.

The injection system really smooths out the .625 lift cam at idle. I have it set to idle in open loop and go into closed loop at 1400RPM. It will NOT idle in closed loop..LOL

Finally nailed down the IAC this evening (Idle Air Control) motor. I couldnt make the damn thing idle. Now, when you fire it up.. it goes to 1300 rpm and then trickles down to 1000-1050 when the IAC takes over. You can watch the voltage to the IAC... it is all over the map trying to keep that V8 at 1000-1050 rpm, but it does it.

Pretty cool programmable system for under 1400$

Try romping on the loud pedal of a full race stroker 410ci 351w with 650HP on the motor alone and a small (250HP) shot of juice just for fun My rev limiter even with a 4 inch stroke is set at 8000 cam lift over .700" and duration at .050" over 310 with 13.5:1 compression it's a blast to be sure but my lowly P-car with a carbed 3.0 is just as fun if not more so. V8s and H6s are totally different animals and each has their good and bad points for me the good point of the 410 in my Mustang is it really is a racecar and I get the total racecar experience that I wouldn't get with a smaller turbo/super-charged V6 or V8. In the P-car I get a whole different experience, almost like I'm driving a F1 car with smooth and quick revs, a unique sound etc. If I ever decide I need a V8 sportscar I'll get a Pantera or a Shelby Cobra. Several years ago I drove a track-prepped Shelby GT350 Mustang and got a similar experience to what the P-car gives me, it's that little bit of nostalgia combined with race heritage that makes these totally different cars so enjoyable to drive. To me the engine is a big part of the experience that makes a 911 a 911 and I wouldn't have it any other way. I think that's how a lot of P-car owners feel and it's a big reason we'll spend 10x more money on HP upgrades than we would on a V8. To each his own to be sure but I'll keep the flat six over any other option.
