Want that Evo 8 500hp build? The Mitsubishi Evolution 8 is a fun car from the factory. If you're transitioning from grandma's minivan to a fast Evo 8, the difference is substantial. But if you're like most car enthusiasts, it wont take long before the stock power numbers are not quite enough. Soon you'll be craving more power. With a long list of aftermarket performance options, where do you start?

Here's a list of the most important upgrades you can make to your Evolution 8 to get there:

Here are the parts that will help you get that Evo 8 500HP Build

While most people stress taking performance upgrades in baby steps, you'll at least need to set an end goal for your Evo 8 tune. That is, you need to know what performance goals you want to make, and then start putting together parts lists based on those goals. In this case, we're building a 500whp Evolution 8.

Evo 8 turbo upgrades

By far the easiest way to make big gains in power for that evo 8 500hp build is by installing an aftermarket turbocharger. The MAP Complete Evo 8/9 T3 Turbo Kit makes it easy to get everything you'll need to complete your installation besides oil and coolant! The turbo is capable of making 500whp on e85, but we'll get to that later.

Evo 8 engine upgrades

the 4g63 bottom end it capable of handing 500whp, but no more than 550whp. Depending on future plans, you may want to consider rebuilding the motor with Manley rods and Weisco HD pistons. However, for the sake of this write-up, you're only going to want to install upgraded camshafts. Kelford TX272 cams are a great choice for 4g63 cams, as the are capable of producing over 400whp.

Evo 8 exhaust upgrades

An upgraded exhaust is another great way of adding some serious horsepower to your Evo 8. It's best to choose a full turbo-back exhaust that has very few bends and contours. The straighter, the better they flow. The Tomei Titanium Cat-Back Exhaust is ideal due to it's availability with either a test-pipe or high flow cat. Furthermore, it's large diameter piping is great for exhaust flow.

Evo 8 intake upgrades

If you've already upgraded your Evo 8 turbo and exhaust components, the next step in your Evo 8 tune for a fast Evo 8 is by installing an aftermarket manifold and front mount intercooler. The Skunk2 Pro Series Intake Manifold and Buschur 65mm throttle body is a must for your Evo 8's engine, as their larger sizes allow more air into the engine. The intercooler setup is entirely up to you, but the HKS R-type front mount intercooler and piping set is a great item. Since you're installing a larger turbo, a blow off valve will help prevent compressor surge.

Evo 8 fuel upgrades

As we discussed earlier, converting to E85 will make the 500whp goal easily attainable. To convert to E85 on an Evo 8, you need to install larger injectors and a high pressure fuel pump. MAPerformance sells an Evo 8 E85 conversion kit that makes this process so much easier, as it includes everything needed for the conversion, including a DeatschWerks DW300. E85 is a great choice because of it's high tolerance to detonation. It's superior to premium pump gas in that most cases it is better than 110 octane race gas.

Evo 8 Ignition upgrades

The factory Evo 8 ignition system is very easily capable of 500 horsepower, but you will need to switch to colder heat range spark plugs. BPR8ES NGK spark plugs gapped at .028 are a great choice.

Evo 8 Clutch upgrades

A Competition Clutch stage 3 kit and lightweight aluminum flywheel will provide 150% holding capacity over stock. It is also a great idea to consider adding stainless steel clutch fluid lines, available from Techna-Fit.

If you follow the above suggestions, you'll be on your way to making around 500whp and having a fast Evo 8. The car will be noticeably faster and garner respect from your peers both on and off the track. Leave a comment letting us know what car you'd like blueprinted for a certain power level. We'd be happy to help you build the fastest Evo or Subaru on the block!
