Whats in store for my X in 2010? Well here is a list of the parts headed my way.
Megan Boost Guage (used but well loved for by Scott)
Forge Wastgate Actuator with 19-24 psi spring
Perrin 3 Port EBCS
ETS 4" FMIC
TurboXS full turbo back with test pipe
And I'll button it all up with a Road Trip down to Kansas City to Modified by KC to get her dyno tuned. I hear nothing but good things about these guys, and I can't wait to see the shop.
So, here are my thoughts on how / why I put this all together. I've already changed out the intake to breath better and replaced the UICP to hold boost better. So continuing down the intake path, I will install a new 4" ETS FMIC. This should keep the intake charge nice and cool no matter how hot it gets. Everybody has nothing but good things to say about ETS's ICs for the X. The stock IC on the X sucks ass. It's tiny and restrictive. Lastly, before the intake charge hits the engine it flow through the LICP. The stock pipe is good on the X, so I am choosing to leave it alone.
Now how will I control this newly cooled and contained boost? I purchased a new Wastegate Actuator from Forge that has a 19-24 psi spring on it. The stock wastegate actuator is rated for around 11 psi. The design of the X's turbo allows exhaust gases to slam into the wastegate and force it open. The stock 11 psi spring just doesn't cut it. Will this increase my peak hp / tq levels? No. It should give me better mid range power and a flatter torque curve. Theoretically it should hold boost all the way to red line, and if I had an upgraded turbo, it would. But alas, the stock turbo runs out of air around 5500 rpm and boost levels start to drop. Now the new Actuator can't do this all on its own. If left up to the ECU, it may be forced to open during spool up and mid rpm ranges. In steps the Perrin 3 Port EBCS to help out. With the 3 port, the ECU will still control boost, but it won't be via a bleed setup but rather with an actual on / off controler. The 3 port will help spool-up happen earlier and make a more responsive turbo. Both the Wastegate Actuator and the 3 port require a tune. They will both cause over boosting. The wastegate actuator will need a tune because it takes more pressure to open it now, and the 3 port does because it will keep boost from hitting the actuator.
Continuing down my flow, the charged air hits the cylinders and gets a good dose of fuel, ignites and flows out the exhaust side. From here it will travel through the turbo and into the bell mouth. Here is where the TurboXS exhaust steps in and frees up the rest of the way. The new exhaust should allow the turbo to spool better and breathe better at higher rpm's.
What will I get form all this? I'm fairly confident that I should see the 350 / 350 mark on the dyno. But the numbers won't be equal like that, the torque number will be higher, so maybe 350 / 365. She should spool nice and low, in the 3000 rpm range. Right now, I'm just looking for a fun street car, and low end torque will get me there.
Oh and lets not forget, I have me a can of paint that's just itching to cover up the chrome on my side mirrors. They are UGLY. A new satin black finish will do them quite well. Also on the coloring block is the chrome that surrounds the trunk release button.
