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.

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?

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.

      I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.

      What should I do next to hold the head on

      By Gareth87 · Posted

      Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.

      Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...

      Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
