P-car 6 or SBC 8, for Ury Options

[Crazyhippy]

Enough of the little horsepower pissing match, it's time for the fast cars to have their pissing match.

I'll be honest, my loyalty to the P-motor doesn't run very deep. They are WAY to expensive for the HP you get. The ONLY advantage i can see from a performance standpoint is the weight, and i'm not sure it's as big as everyone imagines (guessing less than the weight of a decent passenger).

The SBC is easier to work on, builds more HP easily, lasts longer at the same HP level, and sounds better (IMG:http://www.914world.com/bbs2/html/emoticons/flipa.gif) (subjective i know). You do lose the front trunk, but a 914 is not a practical car to start with, so no biggy (IMG:http://www.914world.com/bbs2/html/emoticons/boldblue.gif)

I understand people wanting to keep the bloodlines true and blah blah blah.. isn't that kinda like in-breeding?

please discuss (IMG:http://www.914world.com/bbs2/html/emoticons/driving-girl.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/driving.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/burnout.gif)

I would love to have a wide body SBC 914 that just hauls ass!!

Of course, I would still have a 914 GT replica with a 3.2 short stroke...

And my T-4 superlight autox car.

I think that would just about cover it. (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif)

[Mueller]

not much to discuss, 2 totally different vehicles......

yes, for HP per Dollar spent, the SBC normally wins, but once you reach a certain HP level, the SBC will cost more due to the transmission........

one it not better than the other unless you are building it for a particular class or race org.

Have to beef the trans w/ the pancake 6 too, it's just easier to get to that point w/ the SBC

Imagine a turbo 3.6 in front a 914 box... (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/chair.gif) KABOOM

Can someone weigh street (not stripped racecar) -6 for me?

Thanks

I think the SBC's get out-of-hand pretty quick. Do you really need 500 HP in a 2000 pound car with a wheelbase of a 914? You need to up-grade every everything

Build a 250-300 HP SBC 914 with a 915 and you're safe.

it's much more fun if it's an 1800lb car (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

The 914 brakes are a joke, the 911 stuff is a bolt on, and gives the rotors much more heat handling capabilities so you should be upgrading the brakes anyways (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

the tranny will hold up to 300HP as long as you are not trying to break it. "Drive White" as my grand-dad used to say

The suspension is getting upgraded by everyone, not jus the v-8 guys.

To do a -6 conversion right you are doing the same amount of work to the rest of the car. (IMG:http://www.914world.com/bbs2/html/emoticons/driving.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/aktion035.gif)

book curb weight is 940 Kg

[Crazyhippy]

if my memory is right there are 2.2lbs/kg so 2068lbs total...

That would have to be an early car, and that puts a v-8 less than 100lbs extra (IMG:http://www.914world.com/bbs2/html/emoticons/blink.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/aktion035.gif)

ABSOLUTELY.

Read my blog.

I wouldn't bother with the SBC anymore, If I were doing it from scratch with the right budget, I would be looking for either and LS7 or the BMW M5 Engine (although I expect it to be really heavy).

I knew you'd say that (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif)

OK, do you need 500 HP for the street? (same answer, I bet)

Paul

[scotty914]

no but a stock weight 914 with a 250 hp turbo suby would be great, and would run circles around 95 % of the cars out there

as a owner of a SBC 914 i couldn't agree more. 300hp is more than enough to give you an ass kicking thrill.

i've got a 327 that i'm planning on dropping into my 914 after paint. i'm gonna try and keep it around 300hp (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

and as long as you don't have to smoke the tires your tranny should be fine.

[Mueller]

all of that HP is worthless if you have no place to use or worse yet, don't know how to drive..........

[Crazyhippy]

The 78 factory squirels are useless if you cant drive... (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)

SBC thats to easy folks put it in any and every thing Ho HUM Boring (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif) I know I am following in Ricks footsteps with the 928 engine so its not uncharted waters. It is also something you dont see every day and can not just go get parts off the shelf to build. But it will have the cool sound of the V8 its going to have the 5 inch long flowmasters (IMG:http://www.914world.com/bbs2/html/emoticons/cool_shades.gif). I would have done the 6 just because I dont like to follow the normal stick a SBC crowd. Now if I had an old 427 L88 or the AL. block ZL1 OH BABY (IMG:http://www.914world.com/bbs2/html/emoticons/cool.gif) You know what I am trying to say. I follow the crowd but on my own path (IMG:http://www.914world.com/bbs2/html/emoticons/huh.gif)

All cars have a purpose. Mine is Autocrossing on a budget. I would only add maybe 30-40 more ft lbs of torque to be leading the pack of some pretty stiff competition including 2 past National champs.

Truthfully my car is running with in 10ths of a second behind these guys. Yea I admit I'm in Street mod. only because of the cam. But a SBC puts you straight into Prepared.

[Andyrew]

Heres my opinion.

If I were to do it again, I'd really have a hard time deciding between a Turbo subi or a sbc.

SBC's are cheep, crazy cheap. I can get one in a 914 for 3k, with all new stuff. I can also get one in a 914 in 2 weeks. Easy as pie.

Subi's on the other hand are cheap as well, and as reliable as sbc's are. Only problem is that the wiring schematics are incredibly difficult, and 2 weeks becomes 2 months.

Both can make 500 hp, sbc's are a little simpler to make that hp with, and cheaper.

Then theres the 928 engine.
928's have the ultra uber' cool factor. YOu have the respect, but gawd do you have to work for that respect. Firewall becomes a primary issue. BUt if we look past the difficulties of installation, we have some other problems. The 928 engine's are semi limited in their hp. 300 hp is about all you can get, Theres not much modifications you can do to the engine without spending GOBS of money for a supercharger or other serious modifications. But lets say you have all that.. Or your content with 300hp. Repair cost. 928's are the one of the most expensive engine's to repair.

Now we have a P-6
Commonly the most respected. Its expensive out of the box, and repairs are simular to the 928. But its got gobs of hp avalible. But, its expensive. 10k for 300hp done right just sucks.


Anyways, thats what I think.

really? that's not as bad as i remembered it.

i figured a non-factory engine moved you straight to Modified.

all the engine-swap guys i ran with were in E-Modified.
(or Open Street Prepared - for the guys that wanted to try to put down lots of power on DOT rubber - but the only guy in my Region that did that seriously owned a tire store. i think it was the only way he could afford to run his SBC (mightta been a SBF...) 240Z...)

[URY914]

Change the engine = modified.

As you said this one is completely subjective, but I've had both and IMO the Porsche flat six is a thousand times better.
My V8 made more torque, it made more power, it didn't weigh that much more, it was cheaper to buy and repair and upgrade, but it was just an engine.

The Porsche flat six is more than just an engine. It is mechanical art. It gets to me and makes me feel as if I am ripping up the french countryside in the 24 hours race every time I drive it.
It is so smooth, and gets smoother the higher it revs.
The V8 acted like it resisted revving high, and only did so if I forced it to do so.
The six on the other hand, begs to hit redline. It loves 6000+ rpm, and seems as if it would prefer to be there always.
Add a little postive manifold pressure and it only gets better.

I thought I would really like a V8 914 until the first time I drove mine. That was the only Porsche I've ever owned that I didn't love. In fact I couldn't wait to sell it. Nothing wrong with the car, it was reasonably fast, handled good, and was very reliable. I just didn't care for it. To me it wasn't a sports car anymore.

Others have them and love them, that's good. My experience was just different than that.
