For VQ25det powered M35's:

Transmission cooler

Dump pipe

Front pipe & high flow cat

Coolant mod

Nismo thermostat

In that order

Only then start looking at other stuff such as an brakes, intercooler kit, suspension, turbo, cat back exhaust

Before i got my M35 i pre ordered a few things. When i go it i installed Coilovers, HDi intercooler, cat back exhaust, Boost controller, and an ajustable BOV.

All of those combined made a huge difference, but after a day on the track the Stag showed a few weak spots. Overheating, no grip with current tyres and a lot of understeer.

I am now changed the direction which i was going and looking at improving cooling (Alloy radiator, trans cooler, oil cooler, thermo fans etc), after all that I'll be looking at bracing and sway bars and tyres obviously.

Don't put thermos in your car. It has been proven with our cars over and over that they can not pass as much air as the standard clutch fan setup. Everyone who has done it has than changed back to the stock fan setup

What i meant was a thermo for the A/C as the standard one was removed for the intrecooler, the clutch fan is going to stay

I doubt that they'd ever know; a front end, or front 3/4 impact would write the car off anyway; cut REO or uncut REO.

I would be boxing the cut away section, to win back some rigidity; the REO is what locates the chassis rails, and absorbs suspension loads.

why is a trans cooler so important ?

not planning on tracking or dragging mine..

can't the trans handle a lousy 220awkw without shitting itself ?

I have never seen a transmission fail because the oil was being cooled too much.

You don't have to do it; no one has a gun to your head.

Agreed, as do all of the transmission rebuilders I have spoken to.

That said, it is possible to cool the trans fluid too much which is exactly what I did on my NM35 when I replaced the radiator which did not come with a trans cooler built in.

I ran two external trans coolers (trans > PWR > Mishimoto > trans) which kept it a bit too cold in winter as did not have 5th gear for the first 25mins of my old daily trip to work.

Conan, 220awkw is roughly a 65% power increase over stock. You don't think increasing the efficiency of your cooling system, which was only designed to manage heat generated at stock power levels, would be a worthwhile investment?

    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
    • The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.
    • Just like in being 14mm too small (296mm) makes it not fit, being 14mm too big (324mm) it also won't fit. You want to find the correct rotor.
    • @GTSBoy Ok so that was the shops problem...they showed R33 rotors on R34 page and i did not know 296 do not fit(and are for R33) Yes i bought "kit" with rotors and pads. Pads are ok(i have GTT calipers front and rear). They have some 324mm but no 310mm. So i dont know if they would fit. I have 17inch LMGT4s So another question. Can i fit those in the rear or they are just "too" big for that?
