Turbo Upgrades for the GUIV TD42Ti

[MudRunnerTD]

Yes and like I said is all achievable on stock equipment too although it wont be as nice as something with a Borg Warner on it. Yeah the standard cooler just isnt big enough once you start leaning on it, it just loses efficiency. If you go to a full 4" intake and a Borg Warner EFR6758 then it will be a very nice car to drive. Keeping in mind that your pump is going to be the factor of restriction.

Seriously looking at changing to a 600x300x76 front mount. The cost saving would pay for the airbox and half the snorkel probably. Are you happy with a front mount mate?

Yes. Front mount or ultimately Water to Air. And to go further again Water injection

Yeah I did wonder what gear it was in too.

So Matt you reckon a 20kw increase is possible just from the cooling of the intercooler allowing a bigger tune? 20kw is a great result!

Does anyone know what airflow diameter the Nissan snorkel would equate too?

@mudski, what did your snorkel cost mate?

Thanks fellas, this thread is developing well. Excited about making some changes finally.

The Radius fab snorkel was $690 from memory...

Mat. JPC told me they do their runs in 4th. When I had my car at 4x4 Obsession, they did the first dyno run and the outcome was just about identical to JPC's, 3kw difference. Was different after the snorkel and box was fitted though.... And they do theirs in 4th....

As for the fuel pump. I wired mine in so it comes on only when there is oil pressure. Quite easy to do. Just wire a relay an as per normal, but the earth for the relay you just tap into the wire going to the OEM oil pressure switch. For me I didn't want it to run when the ignition was on. As when I do electrical work on the car sometimes I need the ignition on. So I didn't want the pump to be running. I could have just put a switch in to turn it off but I have enough switches already on the dash. Lol. Plus priming the fuel filter by hand only takes a minute or two to do so...
I also made a bypass fuel line around the pump just incase the pump died, so their would be minimal pressure loss from having no pump. The carters I think can still draw fuel through when not running, but I think i did find somewhere that there is pressure loss. So making up a bypass while I had access to the rear tank was no biggie to me.
Each to their own on this... It suits me.

the fatz snorkel and air box was around $1100 if i recall correctly Darren

[Kimbo63]

$600 for the millweld they all look alike to me

JPC are either lying or there dyno isnt calibrated. The runs hodge posted should be pushing towards 130km/h in 4th easy as his wagon should have 3.9 diffs.

@nissannewby should I be concerned about putting an overflow bottle on my W2A IC?
Does it really require one?

It will just act as a reservoir. Your W/a system will be charged so it should not be an overflow as such? Mine on the GQ is anyway but it's an unusual setup.

I would have thought an overflow or expansion chamber was not required as you want to avoid air in?

That makes sense! Mine too is sorta odd, should work a treat tho'!

Yeah dunno what to say. As my two runs from different workshops were almost identical. Anyway, dyno run, dyno bum. As long as the user is happy...lol
As for the FMIC Mat. As we know these kettles like to get hot. Would having something else in front slowing air flow to the radiator just make it run hotter. But, I kinda like the idea of W2A.
One day I might change mine.
