Hey everyone-
I'm
Mike. I'd like to introduce my build project.
The Intention of this forum is to educate you, and even serve as a guide, whether you pursue big power or just a simple bolt-on turbo kit. So, with that in mind PLEASE Do not hesitate to ask questions! I'll answer them to the best of my knowledge or at least point you in the right direction!
For more info on the car, check
http://www.turbocharged350z.com
Here's where our starting block is:
The vehicle is a 2003 350z Enthusiast, with a bone stock original engine.
Current Modifications to the motor:
I'll list modifications to the rest of the car later. Here's the meat and potatos of the current setup.
Turbonetics Single Turbo Kit:
This kit features:
- Turbonetics Ball Bearing 60-1 turbo with a polished compressor housing
- Aluminum Intercooler Piping black chromed
- Polished Stainless Steel exhaust piping with V-band flanges
- Spearco Bar and Plate intercooler with W.A.V.E. Technology
- Turbonetics Raptor Blow off valve
- Turbonetics Evolution 35mm Wastegate
- Walbro fuel pump
- Upgraded fuel injectors
- All hardware, couplers, T-bolt clamps, V-band couplers, and gaskets
So what the heck does all that mean?
1) The turbocharger is ball bearing, which aids in quicker spool and off-throttle response, while the size of the turbo allows for excellent flow to gain top end power without the turbo fizzling out, and the compressor housing is polished for that extra engine bay bling!
2) Aluminum intercooler piping dissipates heat far better than steel, and the black chrome is just plain beautiful. No need for paint or powdercoating, it's show quality out of the box!
3) Stainless Steel exhaust piping does not rust and resists corrosion far better than mild steel, plus polishing is extra bling too! (If you could see it, that is)
4) W.A.V.E. Technology simply means the intercooler is extremely efficient with very, very low pressure loss and excellent radiation cooling abilities.
5) The Turbonetics Raptor blow off valve has a mean, distinct sound that will get attention from everyone!
6) The Evolution wastegate is a new design, extremely solid and reliable, and runs an 8psi spring.
7) The Walbro fuel pump provides more than enough flow required by the increase in air, as well as the upgraded, higher flow fuel injectors.
8) Unlike many kits out there for other vehicles or even the Z, all gaskets, hardware, couplers, and T-bolt clamps are provided. T-bolt clamps for intercooler piping are significantly stronger than normal hose clamps and when tight will NOT let piping pop apart under boost!
Motordyne Isothermal Plenum Spacer
What is it and what does it do?
Well, in this case I'm using a 5/16" spacer, which by my research appeared to be the perfect spacer in terms of useable power gained and peak horsepower.
The stock upper plenum on the 350z is angled downward toward the front of the car, decreasing the amount of air available to the front cylinders. The plenum spacer eliminates this issue and allows extra air into the plenum collector for more power. The one on the car uses isothermal gaskets to isolate the plenum from the hot metal of the motor.
Jim Wolf Technology Oil Pan Spacer
Jim Wolf's oil pan spacer is exactly what the title says. It adds an additional quart of oil capacity, as well as additional cooling surface for the oil pan, and gave me a better surface to drill and tap for the turbo oil return line than the block itself.
DEI Cryo2 Intercooler Sprayer
This uses the expansion cooling of Carbon Dioxide from a spray bar on the intercooler to freeze over the intercooler, cooling the intake charge, making for denser air and therefore more power. Carbon Dioxide or Nitrous Oxide can be used in this kit, but I prefer CO2 for the non-flammability properties as the tank sits in direct sunlight in the hatch area.
What does all this add up to? Minus use of the intercooler sprayer, on a day with temps in the mid 80s, and humidity at 100% here in Florida, as well as the air conditioning on (don't ask me how that was overlooked), the car put down 371whp and 379 ft-lbs of torque at 8psi, with a very safe air/fuel ratio of 11:1.
This power level was good for a 12.5 second pass at 114mph in the 1/4 mile, with a 2.9x 60' time. This is our baseline to work off of!!!!
I and others tend to think there's more power to be had simply getting a dyno on a day with better conditions, but we'll use this as a baseline as well.
SO, What's coming?
