Well it is all happening!

We only have 6 odd weeks to have the car reliable, guaranteed we are coming back with a blown this or that... but also the thirst for a somewhat competitive car in 2009 - you gotta start somewhere!

Duncan - our only legal option is to run the ceramic turbos is it not - or have them rebuilt with a steel wheel CHRA? Someone mentioned earlier that to swap to N1 we would need to be entering the car as N1 spec and actually have an.. N1.

Can't wait to get over there!

You DON'T actually have to have a genuine N1, just enter it as such. But, you need to have all genuine N1 bits on there, such as factory oil cooler, N1 spec turbos etc. I reckon it'd be worth the exercise just to have that little bit of extra reliability up your sleeve.

Keep in mind that technically you cannot run a GTR with so much as an oil cooler if it wasn't on their from factory. Hence nearly everyone runs as N1 spec. :O

Btw, great to have another Skyline there :D

lol you forgot a very important word 2nd in that sentance "dont"

but you are right about the trade off. the n1 turbos are too big, but 16" wheels are too small. lots of compromises.

Is an N1 oil pump required?

I am thinking the higher flow is more likely to cause oil issues without any internal engine mods to oiling for the head. We are trying to avoid cracking open the motor at this stage.

Also just trying to get our hands on some N1 "lagmasters" - one guy looks to have the R34 N1 dumps as well which could be a good bonus - you guys know of any issues fitting these in the 32 with the standard front pipe positions?

Oh and if anyone has an N1 oil cooler, power steering cooler or water pump we are in the market BIG TIME!

well strictly yes, if you run in n1 spec you can't pick which bits you want. but the n1 pump flows less not more than a standard pump. also targa seemed to be easier on the motor than circuit racing you are not doing as much sustained high rev stuff (yes on the big straights, but there is a lot of mid rev tight stuff too)

re the 34 n1 dumps, they of course are also not legal on a 32. I am pretty confident they would bolt straight on though, only difference would be the rear dump has an exhaust gas temp sensor fitting.

i had to get my 32 n1 turbs from nissan on order from japan. no-one else was mad enough to want a set of them I guess :( the 34 n1s are a much better unit (ball bearing v 270o thrust bearing) but not legal

having said all that, I didn't notice any eligibility scruitineering last year at all. Another GTR we went through with clearly had aftermarket injectors for example.

Sweet re: oil pump - Steve already bought one! I do now remember hearing that they flowed less - thanks.

How much were the R32 N1's and how long did they take to get here? Edit: spose i should just get on the phone to nissan eh!!

We are looking at the G4 Racing AP copies - just hoping they will fit under 17x8 / 17x9 wheels

Ben you mentioned being able to run 18x9 under the option rule - what does this entail? Couldn't find it mentioned in the regs.

Stu Benson (tech reg guy for Targa) has told me that cars are alowed to run wheels that were option parts. The R32 GT-R had 17x9, and 18x9 wheels as an option from the factory. R33's had 18x10 optional wheels from the factory. The old CAMS regs had the option rule in there somewhere. Best bet is to email Stu.

Just found the regs. 301.9 http://www.targa.com.au/Competitors/Regula...icalGeneral.pdf dosn't say anything about wheels though?

Hi

Re the options on wheels, I read the new regs and it does not say you can have option wheels so I am not sure you can.

The other thing to remember is that if you run an option you need to be able to produce proof as per the regs.

That proof must be in one of the formats defined in the regs.

Just my thoughts, happy to see the rules that say otherwise.

BT

wheel options were removed in error from the regs, but will be re-included via bulletin shortly. sorry for the confusion.

paul - further to your email, lee also took the turbos off my old GTR and replaced them with something else. i doubt he'd be after big dollars for them. they made 260kw on 16psi and 95ron with a 3.5" exhaust with a very very mild tune.

Hey whats the deal with exhaust regs?

Had a chat with Ben @ Racepace and he mentioned we may be limited to a 3" exhaust maximum on the GTR? Ouch...

Stuart - those turbos were genuine N1's?

    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
    • OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
