Glad to have a V8

[motion]

Hey man, you put a Chevy motor in a Porsche and all bets are off. NOTHING is off limits! You could put a Datsun badge on there for all I care. Might as well go for the coffee can muffler and the white blinkers too. Maybe some neon under the car?

I like the idea and in fact Im going to go out right now and pick me up that 74 camaro and convert it to a aircoled boxer six!
What, with losing all that weight from the radiator Im sure it will be very quick and nothin beats the stylin of a 70's era camaro!

If you could squeeze a big-block into the 911 the following emblem would be appropriate.

Aren't we getting a bit too tough on the guy? So he installed a V8 in a 11 and it works good. So what. It seems like interesting concept as long as it's done well. Personally, i wouldn't do it...except as a way of giving new life to a beaten old 911 when on budget.

I would hardly call a 350+ HP Chevy engine in a 911 a "poser". It would kick your ass back on the porch every day all day for 100,000+ trouble free miles.

Only difference is I would be proud enough of the swap to script "PORCHEV" or 911/V8 on the engine lid.

Wayyy to go Rarly, you tell'em !!!!

Hi All,

Well , I have to agree that any mod done to a 911 is fine in my book , as long as it is not a 'hack' and done nicely.Its the quality of any modification that 'shows off' the car.I have personally owned 13 911's and 2 930's ..fixed 'em and played with them.Modified the hell out of them , blown 'em up , and even crashed one of them.All of them were 'genuine' Porsche , If you call something modified with suposedly O.E.M. parts still Porsche , and dont forget the AIR fiberglass,BB exhaust, PMO carbs ect..
So , im also on the V8 bandwagon for a change, current project underway is a 1975 non-sunroof coupe , with shortened and built 930 4 speed trans,brakes suspension, and a all aluminum 383 ci 548hp @5800rpm 540 tq chevy ( not Porsche ) motor.

No turbo lag, it should be fun !
Weight bias will be slightly better then a 'real' 930.So any one that wants to bash my 'new' car maybe I'll pull a couple plug wires off so we can have a even race ..haha ( just joking so no flaming here , I figure its about time that I leave some blood and skin on a american motor this time around )

Take care

why does that car have two pedals? how does it work?

Hello

Should we go for 10 ?


Im very much interesstet how others worked out the details.

Did anyone made a usable heat system.

Why did no one used the dry sump setup and lowered the complete unit for better handling ?
Is there a ready sump system for SBC on the marked, like for Ford´s ?
A direct bolt on pan ready with the nipples and integratet pump ( I know that the pump drive will not cary the load but you can drive it from the frontend like the add ons too )

The 911 unit is some 5° ankled upward. If you go to 0° or even under, and shim the trany nose around 1/2" down you gravity point will be lower too.


I did this on a 914 and had enough room for a taller manifold ( it would have cleared for a quad weber too ) plus other benefits.
The main reason was to fit the waterpump and have acces to the front pulley drives.

I´m also interesttet into those details like the throttle linkage. This was very heavy on the 914 and i used a old Mercedes MFI linkage verticaly in combination with the 914/6 setup.

Ok on a 911 you might need bull bars then to avoid front axle lift off.

Roland,
They make several dry sump systems for the chevy and I even have one sitting on the shelf. The system adds to the complexity and weight, the Accusump is lighter and controls the oil well. I am using a stock pan and when I pulled the bearings they looked great.
As for the Turbo badge, to each his own, on my RS 3.8 wing I am going to change it to RS 5.7. If it is your car do what ever floats your boat.
I am biulding the engine now so I can attend the D.E. and V.I.R. on Sept. 6,7,8. Hope to see some of you there.

I would imagine that the SBC aftermarket has everything to offer for Chevy that Porsche does for the 911/930, and then some. They've been racing those motors for a long time.
Dry sump systems, Webers, turbos, superchargers, aluminum blocks, fuel injection systems of all types, you name it and it's out there - for a fraction of the Porsche equivalent price.

To me the debate of the Porshev goes beyond economics. The immediate torque of the SBC simply cannot be duplicated by the flat six. Possibly the closest you could come is supercharging, and some 911/930 folks don't even like that!
I had the oportunity to ride in a modified 930 this past weekend. Absolutely took my breath away. The power "on boost" was just ungodly. But those two words are the kicker. If you aren't in the right gear at the right time you fall flat on your face.

This leads me to a question for the V8 camp.
How are your trannies holding up? I'm thinking that the 930 should be a LOT easier on the 915 transaxle than a SBC. The car I spoke of earlier would build boost and start smoking the tires as you went down the road. Rather gradual, not like the instant blast of power a V8 would produce. A freind has a supercharged SC that puts 260HP to the ground. Not too shabby, and dozens of DE events later his trans is doing just fine. So how hard are the high HP V8s on the 915?

I am signed up for VIR 7,8,&9, hope to see you there. Your car received rave reviews before and the pictures support what I have heard -- this is a lot more sorted vehicle then some of the highly modified 'pure' Porsche's one sees at the track.

Hello

See I made the sump from scratch using a old BDA belt driven dry sump pump with in fact adds compelxity but the lower profile and other things pay back. Also the car is used on the curvy roads and driven extrem hot ( say flat out on the highway ) sending the oiltemperatures beyond good numbers even with the deep sump it came with.


Not to confuse other people I allready have done this 914 and the car passed german inspections. And it was not the demand for cheap power that lead to that.
I just think about to collect good informations and parts aviabiltys for those who will follow up.
Maybe some surprissing new input reflecting techlogycall or practical issues.

You can get a 915 or 901 to live with a sbc if the motor is designed for it. I have a chev DZ (302) coupled to a 901 and 901 has held up for over 18 months now. The sbc produces max torque at 6k (360 ft/lb) 420 hp at 7k. short stroke big bore, and long duration cam seems to work. Trannys seem to live longer when the torque pulses occur more frequently with a 6 cylinder max torque occurs every 120 degrees with an 8 every 90 degrees so the load on the gears is smoother with more cylinders.
By having the max load occur at higher rpm also reduces the shock to the drive train.
