Thanks to Directfreak for the list. :bigthumg:



First, let me tell you, a GSL-SE is the best model available to do a 13B Turbo transplant. It already has several things necessary to make the swap easier:



GSL-SE Front Cover - already have it

GSL-SE Oil Pan- already have it

GSL-SE Engine Mounts- already have it

GSL-SE Fuel Line Pick Up (EFI) - already have it

GSL-SE Fuel Injectors (good for primaries)- already have it

GSL-SE Engine Mounts- already have it

GSL-SE Radiator (3 core) - already have it

GSL-SE Air Cooled Oil Cooler (mounted under the Radiator) - already have it

GSL-SE Brakes (Bigger and Better all around) Not needed, but recommended

GSL-SE Suspension (Better all around, and better bolt pattern for aftermarket wheels) Not needed, but recommended



That is just the GSL-SE stuff. For my particular swap, you will still need:



13B Turbo engine (or Cosmo)

Fuel Injection Intake Manifold and Throttle body

Primary Fuel Injectors (the GSL-SE ones are perfect)

Secondary Fuel Injectors (1200cc minimum, 1600cc (Bosch recommended)

Custom Fuel Rail

Custom Turbo Exhaust Manifold

Turbo HKS 63-1

Wastegate HKS GT

Greddy Profec-B – Boost valve Controller

BOV – Blow Off Valve – HKS Racing (the best)

Intercooler – Isuzu NPR

Custom Intercooler Piping

MSD 6AL

High Output alternator (should have come with engine) 80amps or better

Dual sleeve alternator Pulley

2nd Gen Leading Coils with ignitors

2nd Gen Trailing coils with ignitors

2nd Gen Engine Fuse block – to replace crappy “Fusible Links”

High Output Electric Fan for radiator

Aeromotive 1000HP Fuel Pump

Aeromotive Fuel Pressure Regulator

Aeromotive In Line 10 Micron Fuel Filter

Lots of 10AN Lines and Fittings ($$$$)

Haltech E6K with Flying Lead/bridge

Turbo II Transmission

Custom Made Transmission Mount

Racing beat Lightweight (17lb) steel flywheel

Turbo II counterweight

Upgraded Turbo II Pressure Plate

4-Puck heavy duty clutch

Turbo II starter (or automatic N/A one)

1st Gen Shifter housing (another reason to use a GSL-SE)

Turbo II Slave Cylinder

Optima Sealed Battery Relocated to Passenger Bin

Long Battery cables

Reinforce/Adjust the GSL-SE differential

Custom Exhaust Down pipe

Custom Exhaust Pipe to muffler

Magnaflow muffler?.

Intake and Exhaust gaskets- Still Need



GAUGES:

VDO 3 gauge “A” Pillar Pod with:

Autometer Ultra-light 2-1/16 - Boost pressure – MY FAVORITE

Autometer Ultra-light 2-1/16 - Fuel Pressure (Electrical)

Autometer Ultra-light 2-1/16 - EGT – Exhaust Gas Temperature (Needs the probe)

Custom Center console covered in Carbon Fiber with:

Autometer Ultra-light 2-1/16 - Rich/Lean indicator



3 additional gauges under the Sony CDX-Mp70 Mp3 Player:

Autometer Ultra-light 2-1/16 - Water Temperature (Electrical)

Autometer Ultra-light 2-1/16 - Oil Pressure (Electrical)

Autometer Ultra-light 2-1/16 - Oil Temperture

Probably the easiest engine to do the swap with is a s4 Turbo 2 engine as it has a mechanical OMP (if you decide to keep it) and there are plenty of parts availiable.

Make sure the turbo is off a S4 TII and leave the wastegate stock.You won't want to go with anything more than 4-6 psi or she'll blow.Also look at a additional injector controller.You need more fuel than the two injectors in the SE EFI can provide.As for porting its really up to you.Just make sure you have a Air/Fuel guage and make sure it doesn't lean out or else you'll blow the motor.

s4 is 86-89



you'd prolly only want a mild port as your injectors wont be able to keep up with the airflow.
