I don't know if the gearboxes of the FJ20E and the FJ20ET are the same!

And I've read that the RB25-gearbox is the best choice, but they're very hard to find here in Holland, because the Skyline is never sold here.

The gearboxes that are available here in Holland are the boxes of the Z31, Z32 and S14, but I don't know if they fit! Maybe only swap the box and use the FJ-bellhousing?

Isn't it possible to swap the FJ-airflowmeter for an Z32 airflow-meter? You can convert this with the Apexi AFC, am I right?

i've heard of people using the s14 box and changing the bell housing

Hi,

Are those wide body arches available to buy as a kit ?

Update:

In the past months we bought some parts for the swap:

Turboboost-gauge
Apexi SAFC
Forge BOV
Clutch-disc (the original was worn out)
New spark plugs
4 meters off 3" pipe with bends for the exhaust
Supra Intercooler
2 stainless steel T3-flanges
(this because we must replace the turbo on another spot because otherwise the turbo would hit the steering rack. We are going to make a J-pipe so that the turbo would be located near the rocker-cover in the front).
Lowering springs

And maybe we buy another S12 FJ20 next week for 200euro's for spare parts. This because the gearbox we now have is a bit worn out.

We will start with the swap over about 2 weeks....

Update:

Last monday we started with the engine-swap.

We get the FJ20E-engine and the gearbox out of the Grand Prix.
After that we swapped the starter,steering pump, injectorrail, etc etc.

We found out that the FJ20ET has a knock-sensor and the FJ20E hasn't.
Also the ignition is different, we swapped the FJ20E-ignition on the FJ20ET.

It seems that the injectors are all the same, a little bit strange because the NA FJ20 has 143hp and the ET has 190hp.

The ET has EGR and the E hasn't

We gave the ET a new clutch-disc and bolted the gearbox on the engine.
Now it's ready to put the FJ20ET into the Grand Prix, we'll do that tomorrow

Pics come hopefully later today...

Cheers!
