Everybody says that the 944 turbo has the potential of being blindingly fast if modded. What are the best performance for the money mods I can add for a budget of around $1500? I hear that the 944 turbo has all this potential because it was a race car: so what was the difference between the race car and the street car in terms of engine mods? How can I put it in "race tune"?|||The 951 is a fantastic platform for building a fast, track oriented car. But there are a few issues that should be mentioned in relation to this.
First, the things that do the most to make any car faster, often only do so in the hands of a skilled driver. So while countless dollars can be spent making improvements, the single biggest improvement you can make with any car will be to upgrade the driver (back to this in a moment).
Second, any upgrade is a trade-off. Improving the car's ability to corner will reduce it's comfort. Improving the engine's ability to produce power will reduce gas milage and/or engine life. Even after paying for the upgrade, nothing is free.
Lastly: BUDGET! $1500 is not an adequate budget to do much. While my track car is not a 944, many of the upgrades I have on my track car would be of similar price, and $1500 is very close to what I spend on a set of tires (which will last a couple months). Likewise, it would be enough to address an upgrade of part of either my front or rear suspension. Or, if aimed straight at the engine, where it would do the least good in helping me go faster, it would help work out another 5-10hp (though with the turbo, you will find more available power for the money).
With that said, as I first mentioned, the biggest upgrade you can make would be to your own driving skills. The fact is, outside of a very small select group of people in the world, the driver is always the limiting factor in how fast a car goes. A good driver in an average car will always be better than an average driver in a good car. And until you know how to drive a car to maximize it's potential, you'll only be getting a small portion of the possible upgrades you make elsewhere.
But, if you want... the next biggest upgrade would be tires. This is also one of the most overlooked upgrades, but no other part of the equation effects everything as much as tires. A good set of performance tires will help in every aspect of performance.
Next, getting the car properly setup! A good alignment to help get the car into a neutral handling stance and a good corner balancing would take a little less than a third of your budget, and it would improve most aspects of the car (though you will need the skill to actually be able to push the car towards it's limits to take advantage of this).
Next up, suspension generally will offer the next biggest bang for the buck... a good set of adjustable AntiRoll bars will help with weight transfer and greatly improve the car's turn-in and exit. Likewise, a new set of springs and dampers can greatly improve the car's capabilities.
These items, and safety equipment, make up the main differences between a street 951 and a race 951. While engine mods can be numerous, the fact is that improving the car's ability to carry speed in a corner will do more for a laptime than adding even 75hp (and it will be less costly). Also, going for lightweight parts and stripping unneeded items (weight reduction is just as good as adding power... especially with items like wheels, where you are reducing unsprung rotating mass).
Of course some engine tuning is generally carried out for racing, but generally not of an extreme variety, since reliability can be much more important than absolute power output (driving half the race in first and then retiring with a failure is just a DNF). For the turbo, anything that helps the engine breath better, and some different DME mappings to take advantage of those changes should find a good chunk of extra power without costing too much in terms of engine life and reliability.|||Or go to lindseyracing.com and get their 270rwhp kit for a little over $1,000

Probably the most bang for your buck would be a really good exhaust system but don't expect more than 12-15 HP out of that.
To get real power you'd need a bigger turbo, internal engine work, etc., none of which is in your budget.
Besides, it's always best to work on suspension and brakes BEFORE you make a car faster.
