450 HP ENGINE CONTROL SYSTEM UPGRADE FOR
1981-89 280ZX/300ZX TURBO
Description/Parts List
Purpose: This conversion is required when horsepower requirements exceed the limits of the stock in-
jectors and flow meter. Note that a working knowledge of the control system is required before at-
tempting this conversion. This conversion is not intended for applications subject to specific emission
control requirements and should not be used for such applications.
Parts needed:
1. We supply 420cc injectors. On 1986-89 300ZX-T you will need a fuel rail set from a 1984-85
model that uses top feed injectors.
2. We supply 6 dropping resistors. Note: 1981 already has dropping resistors and doesn’t need them.
3. We supply the Ford Mustang Cobra MAF and harness adapter plug.
4. We supply the MSD 43 GPH inline fuel pump for 81-83 ZX-Ts. Use 90+ 300ZX-T for other Zs.
5. We supply a note sheet along with the conversion parts to explain the steps of installing some of
the parts and some other required changes.
A few of the following parts must be obtained on your own:
1. You supply an ECU from a 1988-89 300ZX. See additional info. page for useable part numbers.
2. If you have a 1982-83 280ZX-T, you supply an “encoder disc” from a 1984-89 VG30 Distributor.
(This is under the distributor cap and dust cover. Mark which side is up before removing.)
3. If you have a 1981, you must also convert to a 1982-83 distributor and drive.
Additional Parts Recommended to Obtain the Best Power Gains:
1. Turbocharger upgrade: The Wolftech Sport 350 (350 HP potential,) is a bolt on. T
Sport 400 (400 HP potential,) is a bolt on and requires a larger inlet hose. We now have a
Wolftech Sport 450 Turbo (450 HP potential,) call for current price.
2. Boost controller: We have a basic manual boost controller or an electronic boost controller.
3. Intercooler kit.
4. Free flowing exhaust system.
