Silvia S15's cam in base models and Autech models.

Spec S came with 5 speed manuals or 4 speed Autos.

Spec R came in 6 speed manuals and I think Auto as well but ADM.

Autech models I heard come in both, manual and auto.

Is there a model thats NA and not autech? Like just a sr20

LOl, No, I am talking about a hardtop s15 pretty much like the autech version, without the autech if you get that?

Yes, in Japan, they were the Spec-S'.

Almost, Were the cars Autech tuned made especially for them for that reason? If not were there detuned versions for sale for say a NA s15 silvia

The Varietta was built by Autech and based on the Spec-S model.

Powered by a SR20DE (N/A, same as the Spec-S in Japan) and with a choice of the 4-speed automatic or the 5-speed manual.

Was released with a retractable hard top.

Autech specifically tune Nissan cars.

It was founded in 1986 as a subsidiary of Nissan.

They also tune the engines for the Nismo R34 GTR and 350Z JGTC GT500 cars.

Ok So s15's sold in Australia spec S and spec R were both sr20det, while the s15 spec S in japan was NA and the spec R -det.

Edit: Just read somewhere else that jap s15 spec S sr20de isn't allowed to be imported, Would that still qualify for sevs import or just not at all?

I believe so.

You will have check with the Car Importing business.

ie, go and ask an import dealer or PM Iron Chef or Carizma International on here (SAU).

If they cannot not be imported, they might explain why both of the ADM S15 Spec - S and Spec - R's are turbo.

The local Nissan dealer must did a bit of a marketing and took Spec - R's, badge them as Spec-S', removed add on parts like the spoiler and sold them cheaper.

They imported the Spec - R sold them for more and would have had all the add on parts.

Then the Spec - R GT came out.

Spec - R GT = Spec - R but with a larger rear spoiler and shiny metal add on parts and I think leather seats.

Mostly cosmetic changes I think.

    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
