Nice write-up Greg. A question - does anyone know who manufactures the HKS pistons? How good are these and is the option of nickel coating worthwhile?

Nice write up! Have already decided on just this approach for the missus 4 door auto Skyline (although she doesn't know she's getting one yet!). For the sake of being pedantic, extrapolation is estimating a value outside the range of measured points, interpolation is estimating a value that sits between two measured points. Gav

Actually, one of the benefits of the hot wire MAF sensor that's in the majority of factory cars these days is that it self compensates for differing air charge densities caused by variations in moisture, temperature and altitude. The principle of operation relates directly to the cooling effect of the air passing a heated wire of known thermal and electrical resistance. The cooling effect is a function of both air density and flow rate. In theory I can see no reason why a MAF sensor shouldn't also compensate for any artificial compression of the charge air (i.e. ram pods, super chargers and turbo chargers) as well. I would assume that the reason most manufacturors don't place these after the turbo charger is that they are very suceptible oil fouling and there is more likely to be oil in the charge air after the (oil lubricated) turbo. Edit: I know the thread starter didn't want theories, but just my 2c worth

I manage a metallurgy laboratory. If someone can arrange for sample of the substrate (a gram is plenty), I'll have an analysis back within 24 hours as to whether it contains any platinum group metals (Pt, Pd, etc) or indeed anything other than what's in a normal s/steel alloy. Cheers Gav

Yes it will

Agree with Ken. Whilst this is borderline with respect to the site rules, in my books it is unethical.

One of the few remaining benefits of being in Australia is that you have the right to take this to court if you want to. They cannot give you a greater penalty - only what you have been charged with plus court costs. If you do elect to take it to court, you have the right to request the officer's statement that will be presented. Make sure that you do this as the version presented is often very different from your recollection (or reality?). Good luck.

Quite easy and inexpensive to have manufactured locally. Although mine are in s/steel, personally I would just use a good thick mild steel as it's a good idea to get them ceramic coated to help keep underbonnet heat down. Mine are off atm and in Perth - PM me if you want to have a look at them.

PMs sent last week - are you still interested in selling?

Bit of both - but this is std PFC anyway Short answer to your question - there is only one language version available

I know I sound old (I am!), but first mods should be to your driving skills. Take an advanced driving course - great fun and may well save your life one day! Also, consider a basic car maint. course. Even if you don't end up doing any work on your car after the course at least you will understand more about how it works. Good luck.

Bear in mind these aftermatket oil pumps can empty a std rb26 sump at high rpms faster than the oil can return back from the head. Consider an oil restrictor or sump upgrade as well.

I'll jump in that one with ya Paul - drop me a PM. Cheers Gav

Yes there is a NA version of the R34 available with ATTESSA. I don't believe it qualifies under SEVS, however.

I had one of these in my GTR previously. Feels almost like a stock clutch but survived a LOT of abuse. Highly recommend for a RWD car.

All OSG clutches for GTR are push type. They sell a conversion kit seperately to allow fitting to a pull type setup as fitted to late R32 and R33 GTRs.

Interesting thread Anyone know how the D-Jetro PFC deals with this phenomenon/problem (if at all?)

Ah Pete!!! I bet it really hurt when you sat down and listed what you've done and what you've spent! Don't know whether to wish you good luck or not - sorta dumb founded really.

What size rims needed to clear these?

What do people most commonly use for higher performance GTR sumps used on the street? I have some reservations with the Trust extension design as it becomes the lowest point under the car and looks prone to speed bump damage. My thoughts are that the std sump is too small capacity for high volume oil pumps.

Heard some rumours that an R34 may be fitting the same terbs in Perth soon?

Sorry SK - you replied whilst I was compiling my thoughts/post!

The PFC doesn't know/care what type of motor you have. It relies on the various sensors. The fact that you are staying with a single terb means that you only need a single AFM (which is what the R32 gts-t PFC would expect). All the other sensors should be transferable between the RB20 to the RB26. The PFC for this model is available on special order and will take a little longer to arrive as well as being a bit more expensive. Personally I would think that it would be easiest to get the gts-t PFC rather than change looms and add the additional sensors (inc. a second AFM) that the GTR PFC would need. I would suggest that a Q45 afm would be needed if you go this route. The Autronic solution is, of course, also viable although I suspect this will be more expensive. There are ECU loom adaptors available from Japan tha will save you cutting your existing loom. Another option is to have the standard ecu reprogrammed. The route you choose probably depends on how comfortable the workshop is with their and your preferred option. Good luck!

The R32 GTR manual covers the gearbox indepth. The R33 GTR box is the same except the clutch in a pull type.

V-Nice! What make is the terb manifold?
