That would explain why a slightly moded jap spec will spank an aussie version with the same mods. however start changin the oz spec engine managment and u have the identical car!

Don't forget guys with the aus version S15 if you go for an aftermarket ecu,

Eg: Apexi Power FC you have to switch wire 30/31 on ecu wiring harness to run the fuel pump & i think the CAS.

:D

jap spec has bigger injectors, and a 6 bolt roller bearing turbo compared to the aussie 5 bolt. the steering wheels are nicer in the jap spec, the exhaust in both is very simiar and from my experience the difference in boost is minimal if at all different. ice performance have told me that the most they are able to speeze out of the aussie spec is about 180rwkw and jap spec more like 215rwkw. I have witnessed first hand two of my freinds going at it. one had a stock japspec the other an aussie spec with catback exhaust, and the japspec raped it everytime

Australia is also hotter and has shitter fuel, so the ADM version has less timing in it. Another reason why you see stock turbo JDM S15 crack ring lands when kids ram in 1 bar of boost with the stock ECU/tune and go to Mexico.

Jdm makes 184kw@fly. Adm makes 147kw@fly.

As noted above Jdm has more timing advance.

Jdm has digital climate control, adm is analogue.

The Jdm's imported where the pre Adm years so i think that was 99 and maybe early 2000.

I wouldn't worry about which one, just buy the best condition example you find. Personally i favour the Adm version as there is less chance of the odometer being wound back and less chance of rust due to climate conditions. They are things to definitely check for on either model.

Aussie versions of cars also end up with factory immobilizors where the Japanese ones won’t 

Then you install a JDM ECU, swap the 2x CAS pins and 1x fuel trigger and off you go - or BYO Haltech/Link/MoTec/ etc.

Poor effort on the NATS lol.

My stock NA 86 makes more @fw than the ADM S15.

I don't want to talk anymore about this though......

 

I like my 86, but I lay awake at night thinking of what could have been.......

Yep, except an s15 can make 200rwkw tuned and around 220rwkw on e85.

Sadly I missed a ultra low km one owner ADM when I was looking.

 

The thing was like new, stored, it had 5000km on it if I recall right, it sold for $28k I believe, which I would have paid.

It was red, a yellow one, exact same condition, owned by the same guy sold about 2 months prior.

I doubt I will ever see one in that condition again.

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
