i want2500 lbs 400 horses
what car should i start with

[Oh Haha]

A 930.

400HP is pretty easy with some bolt-ons.

Remove some weight and you'll hit your target. You may have to replace some metal panels with fiberglass but there are several good makers out there.


That being said, how fast do you want to spend?

Speed doesn't come cheap.

400hp is too much for the 915, and it's somewhat difficult to add the 930 trans to a non 930, this makes your choice easy. Unless your budget is tall, then you can make the 930 trans fit or jump up to the g50. But if your budget was tall, then you could just get the 930 and be on a head start so to speak. I'd get a 930 and lighten it up.

490 hp around 2400 lbs

[Oh Haha]

Is it a turbo? If so, then you can easily get to 400 hp with engine mods. Weight reduction is just a matter of removing stuff you don't need/want and replacing metal with f-glass or carbon fiber.

If not a turbo, then prepare to spend huuuuge $$$ to get 400hp. There are several options including turbo kits and even supercharger setups.

You could also go the V8 install kit route.

not a 88 930 you say huge money how much

[Abigbadjohn]

how did you get down to 2400lb please

Obviously, I can't quote exact prices as parts vary but I would say, for a non-turbo 911, without just cramming a V8 in it, probably well over$10,000.

My SC weighs around #2850. I don't have a/c or power seats so that helps.

How light you want to go depends on how much you want to spend. I would suggest you spend some time doing a search here, reading posts buy the guys that have invesed time/money into lightening their 911s.http://forums.pelicanparts.com/porsche-911-technical-forum/400784-how-much-do-you-weigh-2800-85-a.html

Are you capable of doing the work or would you farm it out to specialists?

As I replied to your initial posting, speed costs money and ,with the right amount of $$$ you can make your 911 into whatever fits your needs.

I hope this helps.

You could also install a 3.6 liter engine from a 964 or 993 but getting it to 400HP will still take some $$$$.


Here's an engine for sale right now in the Pelican ads. http://forums.pelicanparts.com/porsche-911-used-parts-sale-wanted/509857-new-2-7l-hot-rod-motor-motec.html

If you want something that you can get in and drive anywhere, I think you are going in the wrong direction.

400 hp is tough to get from a 911 motor without having concerns about reliability. (Fuel may be a problem as well. Most likely, race gas would be the required diet.)

I don't mean to discourage you but these motors get very difficult to gain hp once you get to around 250-300hp. .

Protomotive Stage 1 turbo kit for a 3.2 will get you to 360HP with 6-7PSI of boost on stock compression/pistons, that's about the cheapest way to get in that ballpark and still have something that's not miserable to drive unless it's flat out. For example: http://forums.pelicanparts.com/911-930-turbo-super-charging-forum/585401-turbocharged-my-3-2l-carrera.html

Selling your car and buying a turbo already tuned would be about 25-30c on the dollar on the cost of doing it yourself. Just sayin'.

The 3.3 turbo and the 3.2 use the same crank/rods, and share the same achilles heel - the rod bolts. Once they're addressed, the bottom end is pretty stout, although past 600-700HP you might need to get fancy.

I'd suggest ARP rod bolts, FMOC, suspension and brakes should be addressed at a minimum. Really. Probably need bigger wheels to fit the brakes under, and you'll certainly want as much rubber as you can squeeze under the fenders. And every time you lift, you'll thank yourself if you fit an asymmetric LSD. BTDT.

G50 3.2 is actually a better platform to start from for 500+HP than a 930 (although 964 or 993 N/A would be an even better starting point), because there's more you can use so you end up selling less off - and a 5 speed is really useful; with good headers, turbo and 5 speeds, there's no turbo lag at all.

Big HP doesn't come cheap as you'd be pretty much reworking whatever you started with to get there, it's just a question of how much/how fast. I've heard that Turbo Craft can help you turn that money into shiny stuff pretty well.

why do you have 400hp in mind? You should consider what you want to do with the car... track, street, DE, and then modify it to suit those needs. The simple pursuit of HP numbers can be futile if the car is not balanced. Suspension and brakes are as important in these cars as hp. A 930 may provide you with a great start. Go drive a 930 to understand what your working with then search on pelican for all possible mods...look into a variable vein turbo over stock K27 for less turbo lag etc. Good luck

[quattrorunner]

Simple answer is yes it's possable.
Then it gets technical.
How will it be driven?
You say you have an 88? I think the transmission is G50 which is the great way to start. But next will be brakes and suspension. I would say go and do.

thanx everyone for your inputs i think a stock turbo should be my starting point.i will start looking for one now im going to hang on to my 3.2 for now because i like how the thin body cars handle.

[POORSH]

Look up "rodrsr". The specs of his car is very close to what you're describing. Supercharged 3.2 Carrera motor to a 915. Not sure exactly how many horses the motor is putting out, but very fast.
