S12 Grand Prix with the FJ20E(T?)!!!

[Kevin]

Hello,

A mate of mine got a S12 Grand Prix Silvia with the FJ20E-engine in it!!






This year we want to upgrade his car a bit!

Nowhere in Europe the FJ20ET is ever sold in a Nissan, but fortunately we found the FJ20ET-engine on a junkyard in Holland. (they ordered a SR20DET engine, but unfortunately they got this one from Japan!) Too bad for us!

Before we do the engine-swap, we first are looking for some parts, like a FMIC, Apexi AFC to control the fuel and maybe a stronger gearbox to handle the 200+hp. And anybody knows how to find a LSD? Does an S13 or S14 Diff fit on the S12?

We also like to lower the car a bit, can anybody tell me where we can buy lowering springs for the S12?

And his rear-spoiler is worn-out , so we like to get a new one!! I saw that the most S12 on this forum has a nice "big" spoiler, is this a standard spoiler in the UK? and more important, does anybody has some spoiler for sale?

Cheers ,

Kevin

Thanks, I found the AVO-lowering springs and where to buy them!

Sex on wheels.... gawd damn how I wish we got those in the States... but a VG30E powered S12 is close enough I guess. Well, not ever as good as a FJ, but certainly better than the other two options, CA18ET or even worse the CA20E.

i've seen fj gearbox's on fj.com handling over 400bhp, you need a rb25 gearbox with a uprated tail shaft.personly i would not use an afc, you need a complete managment system and get rid of the air flow meter, i have a large intercooler for sale that i would post, and its custom built for the s12.

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....
