Hello everyone, I recently purchased a 2005 Raptor 350 and am in the middle of a restoration and conversion to EFI and turbocharging it. I have a good bit of experience modifying cars and thought I would try my hand at modifying an ATV. My past projects include a 2JZ DeLorean, VR6 turbo DeLorean and a Turbo VR6 Nissan 350z.
I plan to document this process with pictures as I go so it hopefully will help others do the same.
What I know so far for major components that will work.
EFI components:
-MicroSquirt EMS with 30" harness
-Honda 420 Rancher 34mm EFI throttle body
Fits the stock intake boot!!!!
Integrated Throttle Possision Sensor (TPS) and Manifold Air Pressure sensor (MAP). (MAP should read up to 11 psi)
Integrated Idle Air Control Valve (IACV)
Integrated fuel injector (small EV14 injector style) I plan to have it flow tested
-I plan to use a small GSXR EFI fuel pump and integrate it into the stock fuel tank
-Small universal automotive fuel pressure regulator
-GM intake air temp sensor
-Cylinder head temp sensor (Ebay)
Turbo system:
- RHB31 VZ21 turbocharger with internal waste gate.
-1.5" sch 10 304 SS butt weld elbows for turbo manifold
-Custom machined SS flange for exhaust port
-Custom made intercooler with Bell intercooler core
-I plan to fabricate 1.5" aluminum charge piping and stock diameter SS exhaust
I have all the wiring and connector information for the Honda throttle body and Raptor and will post up a sensor pinout later. There will be a little work to get the trigger signal for controlling ignition, but you don't have to worry about that if you plan to just go fuel only. I need to control ignition because of going turbo.
