Turbo Upgrades for the GUIV TD42Ti

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.
