Z31 VG30E to VG30ET swap list

So here is the question. Why go turbo? The answer is easy, It is the easiest, most efficient and best way to make reliable power in a z31.

Back in 1999 when I started my first N/A to turbo conversion, My research yielded a lot of really BAD information. I am writing this to explain what is needed to compete the swap. Hopefully I will be helping someone out in one way or another.

To begin with you should have already located a parts car or all the parts for a turbo conversion, this alone can be a challenge. Needed for converting an N/A car to turbo are the following parts from an 84-87 turbo Z31 if using a t3 turbo or 88-89 when using the t25 turbo

Main Parts List

• Drivers side exhaust manifold
• Downpipe
• Front crossmember
• Drivers side engine mount bracket (bolts to block)
• All intake piping (from Airflow meter to Throttle body)
• Turbo
• Oil pan
• Turbo oil lines (and water lines if applicable)
• Fuel injectors (260cc/min instead of 180cc/min)- Two styles depending on Lower Intake manifold
• Correct ECU for year car you have
• All applicable gaskets and Fasteners (You will break some)

Note: If you are turbocharging a 84-86 non turbo you will also need the Alternator mount, tensioner (and longer belt for application because the alternator mounts on pass. side instead of drivers side)

Note II: If using a Diabolic Z Products Driver side top mounted turbo manifold you will not need the Crosmember or the intake piping as you will need to plumb the turbo with custom pipes.
