guys i think you should note that it is most probably an "IMPUL N1" not the NISSAN limited edition N1 where only 228 rolled off the nissan floor. 32impul, i have no doubts that yours is the impul spec n1 but the rest of the general public (including me) wouldnt know anything about these special edition cars put together by another tuning house. i think you should say that your parts are "impul n1 turbos" etc to save any confusion between your car and the nissan factory N1 we all know about. ive seen some pics of your car and it is very different from the nissan n1. please tell us more about it! it looks very tidy!

The IMPUL N1 does not come with air-con, ABS originally, It doesn't have whole for rear speaker and rear rain ripper. The bumper for front, side and rear is original plastic item. Gearbox is pull type.

If I remember correctly, A/R 42, M24 is the markings on stock GTR turbos.

That's what those turbos have stamped on them.

update: Here's an old thread you might want to read.

http://www.skylinesaustralia.com/forums/sh...&threadid=11066

These are standard turbos and they're exactly the same as yours:

Merli - The ones in that link actually have much larger compressor wheels than R32Impul's

There's more to turbo's than the A/R ratios it also has a lot to do with the wheel diameter.

I will measure the wheel size when I get to work tomorrow.

Does anyone know the standard compressor wheel size of GTR or N1 turbos?

Yes, you are correct that there is more to turbos than just A/R Ratios :)

but no, I did notice that the turbos from the old thread had larger compressor wheels. Well spotted. It is of no consequence anyway, NISMO N1 turbos have the following markings on the compressor housing:

Compressor Housing: A/R .60 M24

Exhaust Housing: .64 696-2 T695

I'm 99% sure of the info above, but as always, I might be wrong... If I am, than I apologise, but I just don't want someone to purchase "N1 turbos" and then find out they're just stock turbos.

If you think I'm wrong, please feel free to provide evidence in the contrary.

The Turbo's have the same housings as stock turbos but the wheels look slightly larger, hard to tell without verniers. They are in excellent condition and have only done a genuine 37000 km... see the car and you'll no for sure they're genuine.

Impul 32 is definately 50 rwkw more powerfull than another 32 with same boost that was dynoed on the same dyno on the same day. The ECU has been opened and it is standard. Therefore we believed that this power could only come from the turbos.

Doc.

Sh!t I never new that was a geniune Impul gtr. I spoke to him once, and he told me it was a vspec 2, but it didn't have brembros, it had factory nissan calipers sprayed in red. and I'm pretty sure it had air con as well. I did notice the Impul raear bar and the impul instrument cluster. Also the rear GTR badge was mounted on the left side (instead of on the right) which I thought was weird.

Hope we are talking about the car White R32 with the plates IMPUL, stock wheels

hi man, that time I also didn't notice my car is a N1. the reason that the Brembros not in the car is my perious owner (JSV-Alan) he think that the 16" wheel has better handling on the track and looks better than the 17", so he took away the brembros and replace with the nissan item.

Impul is currently under stage 2 mod in BMT, the reborn impul will be build base no the track racing spec. I am quite sick of drag!! and I feel just a bit of waste to turn the N1 impul to drag car.....!!

don't you think?

    • Yeah I've had too many issues with knock off's on the BMW's. I don't want to do a job twice or more because the parts are shit.
    • I read this and thought "ah! I will do this scissor jack on the tow point thing!" I just use my floor/low profile/costco jack and lift the car up by the tow hook itself, then slide jack stands under. Never thought about using scissor into floor jack combo :p
    • Well, my new WMI system took much longer to finalize. I actually missed my dyno appointment last Friday and lost my 150$ deposit. I'll be going back in the next week or two.  To sum it up. I only kept the AEM tank from my old setup. I replaced the AEM pump with a higher flow/pressure ProMeth 30GPH pump. I also swapped over to a 6AN low pressure feed line to the pump from the tank. There's also a pressure switch you cannot see on the pump high pressure line.    This is feeding 6x 200CC direct port nozzles and 1x 500CC Pre Throttle body nozzle. All fittings are Swagelok, because well why not. I also have a 300PSI pressure sensor up front.    I now have my Haltech ECU controlling everything. I start my pump with a basic relay at 5PSI and deadhead it. I then PWM a 3000CC methanol Injector to control flow starting around 10psi. The pressure switch in the trunk, along with my tank level are safeties before I ever get to 10PSI, and then I use my pressure sensor upfront as a secondary safety to cut the WMI and corrections in case the injector blocks or a line ruptures.  Wish me luck on the dyno!    
    • So, I'm back with bad news. There's no jack long enough on this planet that will reach the front subframe. If by some chance there is, it would weigh 200lb's.  I purchased a long reach jack... The damn thing weighted 120lb's and was massive. Didn't even come close, was still short at least a foot. It was a pain, but I brought it back. Next I decided HA! No problem, I'll get an Extra long reach jack. Well, I couldn't lift the box... It must have weighed 160LB's and luckily there was an open box in store. I took measurement and was still nowhere close.  Sadly I've lost hope and have accepted defeat. 
    • Thanks for that tip, niZmO_Man. I think the battery is OK. It's quite a new one, but I'll check. Last time I needed a new battery, everything electronic was fine, except that there wasn't enough current to turn over the starter. I decided to order one of the partial AV system translation CDs from Car Audio Workshop in NZ. That might have some effect, or help me diagnose the date problem. 🤞
