What V6 engine for 911?
 

Hi,

I have seen some amazing 911 V8 engine conversions but never seen a V6 into a 911.
If you wanted to put a V6 into your 911 what engine you would go for?

Many Thanks!

I'd go with a cayenne V6, that way it would still say Porsche on it :D

4.3l?
 

I have been toying with the idea of a GM 4.3l V6. They are plentiful and cheap, decent torque and HQ and I believe they have a similar bolt pattern as a 350. Let me know what you find out.

Seems like a lot of trouble to mount a heavy iron-block pushrod engine? The GM 4.3 ain't that great, I worked on a few of them. Ford Taurus SHO would be my vote:

This may sound strange but the Alfa Romeo V6 Good HP and the most wonderful sound ever!

No.

911 flat six is way too sweet sounding to ever make me remove one for the motor out of a blazer

You will understand if I am a little confused and also very interested in your LS conversion. Were you against the V6 conversion?

Yeah. Theres no point doing a v6. I cant think of a cost effective aluminum v6 that makes any sense. Ay of the better ones use double overhead cams like the afirementioned alfa. That means that you're better off doing an ls conversion. The engine is lighter than any of the iron v6's and it makes more power and torque than anything really.

The main reason people pan the ls engine is because its a pushrod design. However, this is the main design feature that makes it attractive to anyone doing an engine swap. Its tiny comared to anything else. And, the lushrods dont seem to limit the engines performance in any material way. Chevy abosultely did the right thing by ignoring the european manufactueres and sticking
With the pushrod design.

Now, there are two other engines that are interesting to me. First is the subaru turbo 4 cylinder. It makes a ton of power and is extremely light. The second is the turbo rotary wich is more powerful and lighter still.

I have seen conversions with both but not driven themso if you do that be sure to bring it to houston.

Sorry for the misspellings. I cant seem to type on my ipad yet.:)

I have done a Subaru conversion on a 912 and now I am in fact squeezing an Audi 2.8 with an Eaton supercharger in another 912. I will agree with you that the LS engine is the better choice for such a conversion but once I get started with these projects I can't stop.

That's a couple really cool projects. I love that little suby motor. It would be perfect in a 912. Are you doing the rgruppe treatment to the rest of the car?

I considered Audi engines. That's sort of in the family. I'd be interested to hear how it turns out. It's a bigger motor, physically, than an LS isn't it?

GM v6 dohc all aluminum?
 

I have a "junk" dohc v6 from a late GM product, don't remember which car, but it is the same basic unit as the new Camaro. I haven't weighed it yet, its all aluminum, the 4 valve heads and dohc are interesting. In the Camaro it is direct injected and 300 hp, I anticipate there will be lots of hot rod modifications available, and lots in the junk yards as kids get in trouble. So maybe a relatively cheap motor with lots of upgrades, short length, dohc, all aluminum, I just need to weigh it. Kennedy confirms it is the same adapter as the other late GM v6's.

I am planning to try it in a 914 and keep the 901 trans.

Regards.

Interesting. Post pics, please.

With the "early" modern Maserati's being scrapped so cheaply, (I acknowledge the difficulty)but it would be humorous........

Ferrari powered Porsche :D

Your close, but it is not V6, it is H6. Subaru H6, also known as EZ36D. About 260hp., all aluminum and 100-150 pounds less than a 964 3.6 engine. Now that would be a great project!!!

Lot of trouble for only 260 hp.

What does it cost to put in a 993 or 964 3.6? $15,000 to $20,000? What are you going to get on a stock engine? 250 to 280hp? That is the most desirable route, but a lot of trouble or cash to get "only 260 hp".

If anybody has any links to a Subie install, I'd appreciate it. Considering this for my 912E.

There was a beautiful one done on here a few years back with really good engineering. I think it eventually sold for a big loss. It was a neat idea for a daily driver, but trouble/hp/cost ratio hard to figure over a 3.2 or LS depending on how ratio lends itself to your needs.
