DV, there's a dude on the Pelican Motor City sites who dropped a 3-cylinder Geo engine - complete with cooling system - into his 911 or 912. Freaky.

I was just wondering if all you guys with negative or sarcastic responses have ever been to a car show.You seem thick headed.There has been a chevy under the hood of old fords forever,why cause they can,not to mention all the other cross bredds there are but I guess if you don't know how to change a set of spark plugs you would not dream of an idea where you would have to get dirty."Keep it in your sneaker"

Just wanted to post some info about the V8 conversion that I recently performed. The subject has been posted several times, but mainly debates of right or wrong. So here goes.
The car is a 76 911S with a turbo look steel body kit and a RS 3.8 rear wing,and had an RS spec. 2.7 with about 18,000 miles on the motor. After a hard drivers ed the 2.7 lost no. 5 and 6 cyl. so I decided what I needed was something a little different. Then I bought a four bolt main Chevy 350 and installed flat top pistons, shotpend and smoothed rods, Holley System Max cam and intake kit, pocket ported and port matched heads, roller rockers, 7 qt oil pan, windage tray, and MSD multistrike ign. system with rev. limiter, topped by a Holley 750 Vac. Sec. carb. The engine is built so I moved on to the trans., first was to change to an aluminium cased 915 and install custom fourth and fifth gear ratios from Powerhaus to allow cruising at 70mph at only 2000rpm. First through third are stock. The clutch disc is a Kevlar faced unit from Motormiester and a stock 911SC pressure plate. This can hold something like 430Lb of torque, and is as smooth and light as a stock SC. Engine to trans adapter and flywheel were from Kennedy Engineering which were both of high quality.
For the cooling system I deviated a little from the norm. by using an electric water pump from Mesier, this unit is slick, uses 5.7amps will pump 35 gal/min at 9psi. It also is rebuildable and has an estimated life of 2500hrs. I choose this pump to help keep the weight forward. The pump is mounted in the front of the car behind a Griffin 1.25in two core radiator. I did have to cut a hole in the front, ahead of the gas tank but this is the only hole, a piece that I kept in case the car is ever restored to Porsche power. The gas tank I cut down to 15 gallons to allow and air outlet for the radiator. The valance was also cut to allow an inlet and it only appears that a front oil cooler has be added. In the front trunk the spare was replaced with a can of fix-a-flat and a cell phone, but it still has a decent trunk. The coolant hoses are run under the car with a 1.25in hose from engine to radiator then out of the radiator to pump then two 3/4in hose to the dual inlets on the front of the engine block. Two 12in electric fans and a 100amp alternator do a good job of keeping things cool, can get to 210 on a 98degree day in traffic with the air-conditioning on, but runs on the 180 degree thermostat on the road.
The brakes were upgraded with Hawk HP+ pads, and braded hoses. The suspinsion was treated to turbo rear tors. bars, turbo tie rods, front strut brace, Bilsten Sports shocks. The tires and wheels are 17in turbo twists with 215/45s front and 255/40 rear Bridgestone SO-2s.
The car handles well and does not feel tail heavy, there is a little bit of push in turns that did not use to be there but will install adjustable roll bars to dial in. The car is very, very fast and feels like it, however the motor is quieter at speed than the Porsche engine was, no cooling fan. Now you nail the gas at 2,000rpm it pulls like crazy and continues to pull to 6,000rpm. I love it, if you have a desire to do this conversion don't let your opinionated budys keep you from it, believe me they will grin wide when you take them for a spin around the block.

This conversion may not be your cup of tea but please refrain from brow/beating this V8 conversion fan, its all fun....</font>

Finally got a ride in a SBC 911.

Holy S%&*!

Yeah, that 330 hp crate motor from JEGS for $3095.00 is looking pretty good. Now if I could just get the fan noise from a SBC. http://www.pelicanparts.com/ultimate/smile.gif

THE POST THAT WOULD NOT DIE!!!

BuaAHahHAhaHAHA!!!

actually..i dont see anything wrong with a V8..

HP is Hp, i dont really care where it comes from...but i have to admit, the air cooled sound is awesome...out of curiosity, i'd like to see that metro powered 911...

nothings cooler than creativity...

Here is the link the the guy that used the Geo Powerplant. I posted this same information back on 7/25/2000 when this post just started.... We have now come full circle... and we continue on...........

We haven't seen this thread in a while, and the how old are you thread is getting close to having more replies.

Can't have that, nobody is hollering at each other in that one, so no fun.

My take on the issue: Not my first choice, but if it saves a car from the scrap yard because a new engine cost's too damn much, go for it.

Flame away.

Tom

I wonder what the response would be if people started putting 996 engines in their early 911s?

I seem to remember that coming up before, but they wouldn't fit. Something about it being too lang? Someone refresh my memory.

Tom

If I were doing a V8 conversion, I'd use a 454 big block. Cast iron block, intake manifold and exhaust manifolds. I want LOTS of weight back there. Because I think it would be the ideal setup for a modern day Little Red Wagon:

P.S. - I wish I had Photoshop so I could add my wheelstanding 911 to the photo! ;) -- Curt

I think that this one is an excellent example of a powerful fuel injected mid engine big block that would probably handle well too.
I would like to own one like it.

H2O911, is more information available on line somewhere about that car in your pic? Looks like quite a feat of engineering.

<i>"Here you go."</i>

OK, now we're makng some progress with this thread .... :D -- Curt

I dont know if this will go through but here is a try

http://groups.yahoo.com/group/Porschev/files/Gene%20Brudas%20Big%20Block/

it is on the porchev board under Gene Burdas big block. truely a beautiful car!!!

I really don't see anything wrong with anyone doing whatever they want to their car but I have a naturally aspirated 3.2 Carrera that will and has on two occasions left a 5.0 mustang and a 84 Corvette in it's tracks. Not from a standing start, but from a 30 -35 mph rolling start. Standing starts are too hard on the clutch.

Hmmm, personally I like my boxer 6, but this when done right (sounds like this one was) is also cool. The sound coming out of a 911 would be hard to get used to though.

Sounds like you went with a carb that's a tad large. You'd get more bottom end out of a 650.

Again, Cool

Has anyone mentioned that you should post pictures? ;)

I am blown away at how long this thread has lasted! I built the car two years ago.
As an up date the car is still progressing. More power equals bigger brakes equals better suspinsion equals roll cage equals bigger trans and so on. The car is still fun to drive on street but just this side of a full racer car. Now I am at 528 hp, 13in brakes and bone jaring, eye blurring suspinsion, but I smile from ear to ear everytime I drive it. At two D.E.s in the past year I have been moved up a class because I was passing every car in class.
It has been a challange to cool this much HP and I am still not were I want to be, but I suppose like most projects, it is a work in progress.

See ya at the track,
Keith:p

HMMMM not to question you but what is in the motor to make this much horse power, have you had it dynoed? must have what 14-1's in it, what maybe a 430, hmm, just wandering, you drive this on the street?:D Kevin

Sorry just found what's in your motor, I have a 355 13-1's 6 inch rods 45lb crank dart heads (completely flowed $1200 in machine work) with 2.06 valves torker manifold roller cam, pete jackson gear drive, 750 holley barry grant, oval track motor, it will only run on 110 at 1200 rpm, 510 horse, you have to fill me in on your motor guy, how can i contact him? no serious, if you guys can get that kind of horse power out of a flat top motor, I need to contact your guy, Kevin

Just had to get in on this, I think I might have been the only member not to have contributed to this thread. :D

For some pics of a cool V8 Porsche, (it's a 914 w/ nascar motor), do a search for my thread: "eye candy". :cool:

I just read the first and last pages of this post...yeah...i missed a bunch of stuff...

I'm glad people think you can make hot rods out of porsches...

Being one of the younger guys here I've found myself in possession of a 1967 912 (I'll go back to my own list when I'm done) and I'm considering an engine conversion...not now, but in the future...

I know only a little about porsches, but DO know Subarus...and KNOW that Kennedy makes a subaru engine conversion kit. Well...here's the thought...getting 165 hp out of a 912 engine takes big bucks...I can BOLT that in with a 2.5 L subaru block, and not lose any of that great flat four sound...

Leave the outside looking stock, and have a reliable daily driver (can you tell I hate tuning solexes?)

see ya...

who can see all the purists turning guards red...in anger...

Notice this post is self serving only!

For those of you that want to run with the 930's but just can't bring yourself to spend the dinero necessary. May be you are bonded in some metaphysical manner with your SC want 400 hp but can't bear the thought of modifying your mechanical soulmate, have I got a solution for you. Check out the 420hp 914 over in the 914 classified area. I built this car when I would have rather spent my time in the garage than in the house. Now that my life is normal again I need to reduce the toy count and need garage space. By the way it's quicker than the 930. By the way no 911s were harmed in the making of this car ;)

Don't put a 2.5 Subaru engine in!!!!!!!!

Figure out how to get the 2 litre turbo in there - they can make 300+hp without THAT many $$$ in them (the STI ones ex-Japan make 280hp if you can find one).

Well actually i was toying with idea of putting 2-litre SAAB turbocharged engine in the back...lighter than flat six and extremply tunable.

Unfortunately it would be too much plumbing with air/water intercooler and radiator up front...

That sounds like a great idea, Goran!
Don't worry about the minor plumbing problems, you'll figure it out somehow.
I think you should do the conversion and sell your 930 engine.
To me...
:D :D

I've turned out a couple of 290 hp WRX's from my buddy's shop (where I'm part time tech).

300 hp in a 912 would be pretty sweet, but the 2.0 engines cost too much right now...

I can build a 2.2 or 2.5 block into what I want for what it costs to buy the 2.0...Better yet, I can get the 2.2 legacy shortblock (with the closed deck), throw on 2.5 heads, and a big turbo and I'm looking at 400 hp...all day. The Kennedy Engineering kit should work because the 2.0 is an EJ block like the 2.2 and 2.5...

anyone know the dimensions of Mercedes C or E class headlights?? The big oval ones...?? *wink*

That is why this post is staying alive so long. You have hit the nail right on the head.
What kind of tranny would you have in the V8 conversion?
Where is the radiator?

Or how about a bi-turbo V8 from a Cayenne?

On a semi-related note, last week while heading into work on I10 a silver 914 w/flares passed me. I notices twin pipes out the back and it didn't sound like any 2.0 I ever heard. I caught up to him and held up 6 fingers. He smiled and held up 8. Traffic slowed so we conversed a bit...turns out it is a 350 V8, and his dad has a 914/6. Not purist, but a nasty little car. He said "nice car" to my SC, and then went off.

Rick,

I'm a Renegade supporter, so.. complete Renegade conversion package which includes their bad-ass Ron Davis racing radiator.

I played the radiator game for several years and finally got away from all the BS on the market and went with the RH radiator.

This particular car has a beefed up 915. The owner didnt know me when he started gathering the parts and having things rebuilt. I personally wont build a conversion 911 without using a 930 4 speed with LSD. The gear ratios for the 4 speed are almost identical to a Munice 4 speed rock crusher... perfect for the torque of a SBC. It will pull itself from 2K RPM to 7k RPM in fourth gear just by romping on the loud pedal.

WELLLL.. Porsche rumors are floating around a V8 in the 911 some time soon.

"Last time I checked this is the 911 Porsche forum"

Thats funny, because a 911 with a Chevy V8 is still a Porsche 911...

Maybe its not as the factory or designers intended, but it still doesn't change what it is...

I can see the purists not wanting to cut up and modify a classic, but when there are so many 911's that look so similar (1967-???), whats wrong with wanting more performance, more "exotic" looks without the expense of a "true" Porsche engine? You must really hate the guys that want to actually race these things, because they might wreck them...

As for the Chevy engineering being crappy... thats a joke... Sure, maybe Porsche puts out a technically superior engine... But the basic architecture of the small block Chevy remained unchanged for almost 40 years... Is any of the design that Dr. Porsche designed still used? I doubt it... Look at all the different engine styles used in Porsches... Sure the conversion might be a little crude because the engine weights and compartment sizes are different, but its not like somebody having the engine hanging out the hood, etc...

Its still a Porsche, and will always be a Porsche...

Isn't the original VW beatle design still in production, down in Brazil or somewhere?

I think my favorite was this from a few pages back:

"Why the hell do you have a Porsche in the first place if you like pushrod v-8s? It's akin to having a Supermodel with a 1st class from Oxford in Latin for a girlfriend and then slapping on a set of Pamela Anderson boobs and transplanting hooker's brain in so that it's easier and cheaper for you to get your kicks in the sack with her."

Like you wouldn't want her in your "garage". RIIIIIIIIIGHT.
