Just wanted to share some exciting information about an Evo IX that we are working on here at the shop. First off let me explain that the customer wanted to build an ultimate street Evo that can be driven everyday and even on long trips from NY to FL. We gave some suggestions and this is what we came up with....


We decided to stroke the motor along with some other minor supporting modifications to take advantage of the new Mivec head and new turbo. First we tore down the motor completely and wanted to see the exact difference between the Evo8 and the Evo IX motors. I won't bore you with all the details, but let's just say there are plenty of differneces. Even the spark plugs are a different size!

Anyway, some of the minor modifications:

HKS exhaust
HKS Twin Fire Ignition
HKS Intercooler
HKS SSBOV
HKS Downpipe
HKS Intake
HKS 272 exhaust cam
Forge boost controller
Walboro Fuel pump
680cc injectors

Pruven Stoker Motor:
Balanced and bluprinted 2.3 liter
Balance shaft removal
Pruven Pistons
Manley rods
Mitsubishi crank


Dynoflash custom tune


We also left the stock cat as to keep the car 100% emmissions legal. Let me tell you what an unbeleiveavle carthis has turned out to be. I almost never post on here, but the car came out so good that I had to share this experience with you all. We got the car running this past Wednesday and were unable to get the car completly tuned due to time constaraints. One thing I'd like to mention is that for a car with injectors and a cam, this car idles like stock. You couldn't tell this car has any major modifications done to it especially with the nice and low toned HKS exhaust.
Al from Dynoflash was going away on Thursday and was not coming back until today. So we get the car back on the dyno and all I can say is this car is unreal. We started with low boost and we making some nice torque numbers, somewhere in the 370 range with only 18 psi on pump gas. The horsepower was somewhere around 330. As Al from dynoflash was flashing the ECU we were gaining more and more power. Once we peaked out on the pump gas, we decided to put in the race fuel. We didn't really expect much since he has his factory cat still but were amazed at the levels of torque the car was achieving at a mere 26 psi on the stock turbo.

We are done dynoing for the evening, but tomorrow, for testing purposes only we will be dropping the exhaust to see what kind of horsepower numbers the carwill make. I'm not too sure the car will make much more torque since the at the wheel numbers were insane, but I do believe by taking the cat off, for testing purposes, we will break the 400 at the wheel mark!

By the way, the final numbers were, (and these are at the wheels) 375 HP and 490 torque! Just for fun we compared the graphs of a modified Viper (10 cyl) vs this Evo IX and they were dead equal in their torque. This Evo is an absolute monster. After we pulled it off the dyno, I drove it through the parking lot to do a test run and all I can say is this car drives like a Viper.
