I know I am late but there is definatly some sort of middle east spec when I was deployed in iraq I had to disable a whole bunch of cars and a lot of them where brand new at the time with that protective film still on the bodies, to my suprise most of the cars where downgraded with carburators from the factory and other primitive parts my guess to keep the cost down for these poorer regions, the only cars that had fuel injection where the luxury vehicles

they sold RX7's in IRAQ?!?!

and u KILLED them

Btw r33 is in awesome condition, atleast from what I can tell. Beautiful car..

thanks man.. I'd post more pics of it,

Wow, just weird...
7kRPM redline on an S5 - it's an NA gauge cluster, right?
With the voltmeter in the lower left hand corner and not a boost gauge???

Is it me, or the seats look like S4 pieces?

Instead of a rotating sleeve inside the engine, these engines have butterfly valves (just like throttle valves) in the manifold auxiliary runners. The two actuators have a spring in them which holds the butterflies open. The actuators are connected to the intake manifold via an ECU-controlled solenoid. Below 4500rpm the solenoid allows vacuum to reach the actuators, which pulls the butterflies closed. Above 4500rpm the solenoid cuts the vacuum and the butterflies spring open.

does this mean i'd have an easier time removing all the emissions stuff and not having to worry about losing the 6PI activation mechanism like in the USDM versions?
The system is part of the vac rack. If you pull out the rack you'd have to remove the appropriate solenoid from it, remount the solenoid in the engine bay and replumb it. Shouldn't be hard.

does our "less envirnomentally friendly" designed engines compare in performance to the more "green" USDM versions?
I've never seen any figures, but I imagine they'd be pretty similar. Other than the lack of cats, the intake and exhaust systems are pretty much the same. I believe there are some porting differences but I don't know which is best (Higgi?). The less sophisticated ignition system would probably cost a bit of overall performance due to the simpler ignition advance curves.

It's your lucky day. We've just got a new digital photocopier at work which can scan anything into a PDF. I'll scan the interesting chapters and e-mail them to you and Ottoman. It probably won't happen until next week as we're really busy at work. (Ottoman, PM me your e-mail address.)

It's for the 86 model so there are probably some S4/S5 differences to think about. Also it's only a training manual, not the full service manual, but it's still pretty interesting. It looks like it was used to train up the workshop staff on the new model. It's a basically a very detailed description of everything rather than repair or diagnosis info like the FSM.

Weird? thats it?? that's all ur gonna say? b4 the pics u had a bunch of stuff to add..

i post like 20 pics to answer ur Q's and all u say is "weird"
common Ted U can do better than that!

yep.. it's an N/A gauge cluster in km's as well (goes to 260km/h)

how do S5 seats differ? what struck me as odd was they weren't "solid" color.. but had a pattern instead...

Ha!
Sorry, I'm not an NA guy, so I wish I could offer more help, but I can't.

Wow, I would call that rare!

I think the S5 seats are a little better quality?
Your seats has the cheapie vinyl sides, right?
It's been a while since I've peeked into a non-leather S5 interior...

I got the car running tonight... (wasn't when I bough it)

primary injectors weren't firing i took the manifold all apart,took the injectors out.. then put it all back together again... and it worked..

it seemed ok at first... car fired right up.. idled nice and smooth (this NA idles better then my TII to be honest)

the car warmed up... and then **** hit the fan...

from smooth and free revving..there's white smoke pouring out the exhaust too... maybe the OMP has gone loopy and is spraying in oil like mad? or cuz there car has been sitting un run since dec..


to real lumpy and stuttering..

as if the car was running on one rotor...

i'd turn off teh car... let it cool for awhile.. then it would be ok till it heated up again, and went lumpy...


as we've discovered.. the ignition system is teh same as teh GSL-SE... ie. dizzy


in the bottom right corner... the pair of coilpacks sit..



the coil pack is Arcing to the pole/poles around it...

i'm guessing the coil pack is shot?

i have no idea where i'm gonna get another one to replace it. or check it..

unles it happens to be the same on like 280ZX's or something...

Yes, i guess its my lucky day

Euro spec S4 NA FC's are rated at same 110kW like US spec, and even ports are not really different, its just matter of difference in 5-6 ports.

There are no S5 NA's in EU, only turbos. I am looking forward to that pdf
I don`t expect anything really new, as those distributors are covered good in first gen FSM and aux ports we were able to figure out already. It will just be nice to have it as for turbo models we have FSM's.

check your engine to chassis grounds, as well good grounding of coil packs

if your spark plugs are fouled or spark plug wires bad, it could be arcing somewhere out, but its more likely matter of grounding
