Dyno's don't read time, they read rpm vs power (or variants of that). You can see the power under the curve, but you can't really tell the actual response time of the setup.

Good point if you are locked into rpm.

Surely you could set up the bottom axis as time though? I guess some of the old software is probably limiting but it would be a very simple calculation for the people who make it.

oh, yes those pics on RHD are the correct HKS front pipes. one thing to note, they are quoting ID as 70mmX2 and single 85mm. most other places seem to quote OD which makes these approx 75mm X2 and 90mm single when comparing to other exhausts. I'll still measure mine this weekend, but those are the ones. best front pipes I've ever seen. have flex joint, have very, very nice welding, flanges welded on the inside, good quality stainless, extra thick flanges to help stop distortion and etc etc. they are the goods.

Baron,

Just bought a set of front pipes (possibly Top secret drag)

They are 75mm ID into over 100mm ID merge, Coupling this with a pair of Midori Dumps, would this not be a better front front half for a GT-R ?

What an interesting time for this thread to get bumped to the top, only a couple of days before someone is doing -5's on a stroker motor. That timing is such a coincidence its not even funny

Haha. Interested in a set of GT RS's? Going cheap :thumbsup:

Haha,

Thanks for the offer but I'm looking at the same thing as you (-5's) But I only have a little 2.64 odd Litre to play with unlike you big Forklift boys :D

Waiting for my 044's to show so I can finish the fuel system !!!

3.0>2.8.

That is all.

haha paul - were u really that impressed with my rb2630 :)

i now have an rb26 & i personally wouldn't do another rb2630, the car becomes a 'chop shop' & besides that, rb26 revs much nicer & howls when compared to the 3ltr

i also think though, either stick with the rb26 OR if u want larger displacement go straight to a 3ltr or larger :)

Is that like 32>33?

Yeah right! :nyaanyaa:

I have said it before and I will say it again.... After driving your car (and I have since driven Steveo's) you would be silly NOT to go that way. They rev, they do everything a 26 based block does... just better. You only have to butcher the car if you have a 32... the other two is no real issue.

I will say this though... if you have the engine out and WANT to keep the original block you have rocks in your head by staying the standard stroke crank. 77.7 mm at the very minimum. It makes the car so much nicer to drive!

Something I do notice is that not alot of people take advantage of the 26 bore stroke ratio, so realistically for alot of people going the 3.0 litre for lazier power is indeed a good option, particularly if you are beginning a rebuild.

There are lots and lots of very fast 2.6 litre cars though, some of the fastest in the world even.

Racecar is different. For the street a nice fat twist curve rules... Can't always have 5k + on board.

    • Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
    • Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.
    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it. 
    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
