The 600cc injectors on my GTR are well and truely maxed. I am after a set of injectors (probably somewhere around 700-750cc) that will fit straight into the factory rail and plug into the factory loom. I don't want to have to mess around. What can I use? Also, will a nismo fuel pump flow enough to service these injectors. IIRC, they flow 276L/hr. 6 x 750cc injectors -> 4.5L min at max duty -> 270L/hr So, the fuel pump should be okay because the injectors will never see anywhere near 100% duty anyway. Another option is to up the rail pressure, but I'd rather just get the injectors if they are a direct fit. Would I be better off using a HKS or Trust rail and injectors?

After a CAS from an R33. Thanks

The JDM EJ207 makes heaps more torque than the yankee 2.5 Also runs 12 second quater miles out of the box.

Are the CASs on RB25s and RB26s interchangebale?

Can anyone confirm if the waterpumps are interchangeable between R32 and R33 GTRs? If not, what is the difference? Thanks in advance

A head specialist will be fitting the springs and doing up the head.

I'm in the process of building an RB26 engine that I want to be able to rev to 9000RPM. It won't be running huge cams (260deg 9.15mm lift PONCAMS), but I'm considering fitting stronger valve springs. I know I don't really need them, but given that the original ones are nearly 10 years old, and the fact that I am running bigger than factory lift, and I want to rev harder, I think it's a good idea. The question is, what springs do I use? Will Tomei Type A's be okay? They are rated to 10.8mm lift and 8500RPM. Will these be okay for 9000rpm at only 9.15mm lift? The specs on these are 24kg seated and 77kg lifted. Or should I not bother?

Looking at the Tomei RB28 kit, I noticed it used a standard piston pin height (30mm), so needs to use rods that are 2mm shorter than factory. So, the stroke is getting 4mm longer and the rods are getting 2mm shorter, surely that's not a good thing for RPM? Even in standard form , the RB26 rod ratio is a bit lower than ideal for high RPM. Are these kits any good?

Has anyone increased the rod ratio on an RB26? The factory ratio is about 1.65. By using custom rods and pistons, I reckon you should be able to get it closer to 1.71 which should help it make a bit more power due to better cylinder fill and will allow it to rev better.

Since when? It is possible in theory, yes, but that means that the phone will need to connect to 3 BTSs simultaneously at all times. That never occurs. The phone is usually connected to one BTS and connects to 2 BTSs for a short period of time during handoff only. Also, GPRS is a packet data service over the mobile channel, it cannot be used for tracking. The same goes for Tri-band, having multiple bands will not help you track either.

I reckon it's due to the knock sensor circuit picking up the back EMF when the field in the coil on the starter's drive colapses. No idea why some do it and others don't though.

I'm sorry, I don't mean to interfere, but I must point this out. There is no way possible for Police (or anyone else) to track and locate a vehicle using a GSM signal. At best, the current cell site can be determined (which may cover an area of 100 sqaure kms or more!) Even this is floored, as a GSM phone (or car alarm!) won't necessarily connect to the closest cell site (due to channel propagation characteristics like fading and multipath interference). Tracking via cellular systems is curently a reasearch topic for 4G mobile comms (a long long way off), but is not confirmed and will not really be able to provide the the accuracy required to track a stolen vehicle.

But Stock turbos will die after not too long at 1.2 bar and will take the engine with them...

Probably...but it could have done a valve

Ouch...was it pinging?

What sort of boost controller are you using now?

What gear is it that you don't see 15PSI till 6000RPM? My turbos are bigger than yours and I get full boost (1.3 kg) by about 4800RPM in anything above 2nd. I don't think I even get full boost in 1st though.

And the winning STI of last year sold for 100k less

Don't worry about it, have another go next week...and I might join you. Getting the launch right in a GTR with big turbos is a pain...such a fine line between sitting there smoking and bogging down. So, you only got 3 runs? What time did you get there?

How much will these go for? What tyres are on them? What size tyres? How much tread? Are the wheels unmarked?

Does anyone know how the heaters in R33s work? Specifically, does coolant flow through the heater core whether the heater is on or not (and a flap in the heater box diverts the air around the core), or is there a valve in the engine bay which controls the coolant flow to the heater core? Cheers

Don't use a battery that's not sealed unless it is a special battery with a breather hose and no breathers on the caps. You could also put a normal battery in a sealed box and have an externatl breather, but that is a pain. Easier just to get a sealed battery. The reason for this is that the chemical reactions in a battery release hydrogen gas. With a boot full of hydrogen, one spark and...

Thanks. I've never checked it with a CRO, but I thought 1 deg meant 360 pulses/rev and 120 deg meant 3 pulses per rev. But that can't work. Maybe the 1 deg is 1 pulse per rev just after TDC on #1 and the 120 deg is 3 pulses per rev telling the ECU when to move to the next cylinder?? The error checking makes sense, but I can't see why they don't just split the signal inside the ECU case. Also, something I just realised, if you adjust static ignition timing by twisting the CAS, you would also change the injector timing, wouldn't you? Does adjusting the global ignition timing on a PFC do this too?

Does anyone know how the CAS on the RB engines works? There is a 120 deg signal and a 1 deg signal. I'm not sure why both of these are needed. In a 6 cylinder engine, the spacing between cylinder firing is 120 degs, so that singnal makes sense, but what is the 1 deg for? Wouldn't the 120 deg signal be enough? Also, does anyone know why there are 2 pins on the ECU for each singnal input? Thanks

Out of curiosity, how did you notice the coolant leaking? Did the passenger side footwell fill up with coolant, or did it run under the carpet?
