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...

PorscheDV:

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...........
Enjoy...

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.

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
