Build an entire 440 HP engine for $3,200

Hi folks,

Its kinda irritating that you can build a Chevy small-block based motor, which develops 440 HP, for only $3,200 - and that price includes the block!

For a 944/968, you'd need to spend ~$20-25K to get you to 440 HP. Okay, that price includes labor but you have to supply the starting engine.

Makes you think…

If you want to read about the Chevy motor, see http://www.carcraft.com/techarticles/81998/index.html

remember, the biggest reason for the price difference lies in the number of units produced. the chevy block was produced in the millions where the porsche block numbers somewhere in the ten thousands.

You are comparing the Chevy's 6 liters to a 944/968 2.5 to 3 liters. I think a 968 stock at just half the size has more than half the power of this hot rod Chevy.

that's also correct. I always considered the 2.5 as half of a 5L chevy block

So in a 968, with vario cams and 16 valves with roughly 35 years of advances the Porsche can make better than 1/2 the power of a SBC with better than 1/2 the displacement of a 350?

I have not found a better alternative for simple, reliable, affordable power than the SBC.

P.S. The timing chain is good for better than 30,000 miles, and if the water pump fails, your valves don't all bend.

P.P.S. Unfortunately Chrvrolet hasn't wrapped a chassis like the 944 around their engine. We all could be driving Camaros if we wanted.

The Z06 Vette is getting close.

Yeah, the Z06 chassis is damn good. Not quite Porsche-level, but that car has plenty of motor and can kick the similarly-priced Boxster S's arse in pretty much any performance contest. I have an isue of Road and Track where Steve Millen drove a Z06 around Laguna Seca Raceway quite a bit quicker then he drove the 996 Carerra. Pretty humbling for a 996 to get convincingly beaten performance-wise by a car which costs $25K less.

I love CarCraft. For the longest time they had me wanting to build a 340 Duster, but that got sidetracked in favor of a 944.

And I still don't have either of them.

There is no subsitute for cubic inches. Getting 440 hp out of any four cylinder is expensive.

why is it called "small block" if it's an 8 cylinder? how much would it cost to turbo charge that thing? how hard is it to build that baby? why is it carbeurated? wouldn't it be much more powerful if it was injected? how hard is it to make one fit in the 944?

I cant remember all the numbers but a small block is like a 327. A large block would be someting like a 396 or 440. Its all relitive to the size of the V8 your talking about. There must be turbos out there but I couldn't tell you where to get one. It is more common to install a blower on these types of motors. Small blocks have been installed into 944's. There are a couple of kits out there. The cheapest kit I can remember is about $3,000. Then you have to buy the motor and drive train separatly. Total cost of a qualitity conversion would run about $10,000. You would probably be in the 400 hp range. Add a blower and you could get up to 600 hp, but you would need a verry large hood scope to cover that monster. Newer V8's are fuel injected if you went that route then you have to worry about maping the fuel injection and carburators are cheaper and eaiser to tune.

I have never done this so this is just my oppinion. Take it with a grain of salt. There are people on this board who have done it and they would be much more knowledgeable than me.

Actually ..... There is a huge following for Turbo charged V8's...

Take a look at this Mustangs engine bay ...

http://home.earthlink.net/~marklutonracing1/dohcturbo1.jpg

You should see how many daily driven 8-10 second turbocharged mustangs are out there. Its scary.

Chevrolet's small block V8 came in 10 factory displacements:
262, 265, 267, 283, 302, 305, 307, 327, 350 and 400. These displacements were obtained by changing the bore and stroke in the same block's dimensions. Cylinder heads, camchafts, lifters, pushrods, intakes, headers, timing chains, water pumps... all basically interchanged. There were some differences (mainly in the 400 which was externally balanced and the siamesed cylinder walls necessitated unique cooling in the heads), but they all used the same basic block whaich was smaller physically than the big block Chevy (396, 402, 427 and 454).

Turbos were less popular for v-8's for 2 reasons: #1 these engines came with carbs, and you either need to draw through the carb into the turbo, or force pressurized air through the carb necessitating a sealed carb. #2 the v configuration is just inherantly more difficult to plumb for a turbo, or turbos than sitting a blower driven from the crank between the heads, sucking through the carb. However EFI is changing this situation.
