ive got a series 2, but i thought it still needed cutting?

what power is the arc 105mm core good up to?

Im pretty sure but not 100% that no cutting is required. my mate was thinking about replacing his front bar with a series 2 bar cos it didnt need cutting. he didnt end up doing it cos of family stuff

14 will be safe, if your has the supporting mods.

AS for stock turbo untuned, you will get more response and power by running less boost.

Just because you run 14psi doesnt mean your car will going any faster.

Run 0.8 bar max.

That is 10psi.

I can gurantee you the responce will be much better with lower amount of boost.

Once your car is tuned to run a little higher boost then go for it.

Get a 34 side mount, which can handle up to 200-210kw.

ARC are to pricey. 34 cooler will do the job fine.

Why would a car running lower boost be more responsive than a car running higher boost? Do you mean to say a stock turbo with a max 10psi will reach the 10psi faster than a stock turbo running 14 psi would reach 10psi? Or do you mean to say the turbo running 10psi will seem more responsive because it has a lower max boost and therefore reaches it quicker than it would reach 14psi?

For -- (stock ecu, turbo, smic)

1) you car will be running rich firstly.. Every skyline does!! lol

2) You will see more flat spots with higher boost levels..

3) Running high amounts- your plugs may foul up.. So you need to regap the size.. to make up for it..

4) From personal experience and seing it from friends car, when they first started.

5) on a hot day, having that bit extra psi or so wont help you at all.. Car will feel slugish when you really push it, more so with higher boost..

Im just speaking from experience, and i maybe im wrong.. Your car may act differently..

But i found that running that bit less boost, made my car more responsive.. ie i turned it down from 0.8 to .7 bar

FACT: At the drags.. Im like lets run more boost.. at 0.8 i got like 14.5 at best for 3-4 runs.. A guy suggested to me at the drags to turn it down.. so i did one notch.. got a best of 14.0 flat..

BUT who knows, maybe my reaction time was just better...

Maybe others can back me up on this?

either way my car feels better runnin a bit less boost.. that is 0.7-0.75 bar.. I felt no flat spots at track day..

and i still got stock ecu, turbo and smic..

i noticed you posted in that 34 wreck thread from some time ago, the guy was selling his cooler for 80 bucks. did you end up buying?

rang him the night before to confirm meet up.. he goes his dad ran over it?? hmmm

250 does seem pricey.. But they normally start at that price and drop down.. to 150-200

Cost that much because they know its a cheap upgrade for the 33..

on a side note, what is everyone's opinion of china cores?

Very good coolers.. They do the job.. 0-300kw.. has been proven..

Many threads on this topic..

Cores are all the same.. Comes down to which copy has the better pipings..

AS for cutting the bar on the s2, i will confirm with you tonight. My friend does cooler installs.. So i will ask him about the series 2..

Otherwise im sure there are heaps of members on here with s2, with fmic..

i was at Bel Garage one day when they were isntalling a JJR fmic into a R33 s2. they said that if you do it right then you wont need to cut anything away ie fan baldes, front bar..etc..

i have an Apexi front mount with same side return piping which costed an arm and a leg which didnt need hacking either. small core but does the job easily.

well ive actually helped a mate install a just jap front mount in his series 2 skyline, this was a few years ago and im 100% certain that we had to cut some of the bar ( on the bottom of the hole under the 2 lights in the bar) because the piping was hitting against and we couldnt put the bar back on. not sure if anything else had to be cut.

But wen we finished it looked very neat, and you couldnt tell we cut anything

to all the people that said they'd double check, any confirmations that its possible to install a fmic with absolutely NO cutting?

SiR RB: Id expect Just Jap, like other generic core/pipings, to need bar modifications but a brand name cooler might not.

I just fitted an R34 intercooler to my series 1 stagea. It cost me $80. Bunged it in on the weekend. There is the obvious difference in size but also if you examine the cooling fins they are perforated on the R34 intercooler meaning greater surface area to volume ratios for heat transfer.

It has all the power headroom I need for a 220awkw-ish turbo upgrade. I am also going to run a set of cams in the motor later on so the average power will be significantly up adding to the potential heat load but, I am completely unconcerned about heat soak and the abillity of the R34 intercooler to do a decent job. A water spray kit gives me everything back I might lose on a sustained flogging and costs bugger all to make.

You can skin a cat lots of ways. The R34 intercooler is a good stepping stone till you make your mind up about the actual power goals and how much money you don't have to spend on other important supporting mods.

    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
    • @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html
    • These going to fit over the big brakes? I'd be reeeeeeeeaaaall hesitant to believe so.
    • The leather work properly stunned me. Again, I am thankful that the leather was in such good condition. I'm not sure what the indent is at the top of the passenger seat. Like somebody was sitting in it with a golf ball between their shoulders. The wheels are more grey than silver now and missing a lot of gloss.  Here's one with nice silver wheels.
    • It's amazing how well the works on the leather seats. Looks mint. Looking forward to see how you go with the wheels. They do suit the car! Gutter rash is easy to fix, but I'm curious about getting the colour done.
