Td42 non turbo to turbo

[luvpsi]

Hey guys I have a silver top td42 non turbo and looking at turboing it. I have seen plenty of kits on eBay one in particular which is a td0518g by kiniguwa. Now I run of these turbos on my Vl turbo which gets a lot of abuse on the track with no issues so far and they have a good rep as well. The question I wanna ask is is this turbo to big I don't want big power just a better fuel economy with a bit more go and a touch more torque. Or would I be better off with a ht18 or something similar. Also what will I need to change apart from the obvious. Will I need to change injector pump etc

If you don't change your injector pump then grab a 16G with 8cm housing and billet wheel. If you go to an 11mm pump then an 18g with 6cm housing and billet wheel. If you go to the extremes a 18G with 8cm housing and billet wheel and 12mm pump.

You could also grab a garret 2860 or GTX2863.

A HT18 would be ok but doesn't give you as much room to move as any of the above turbos.

How much boost can I run with the 16g and standard injector pump

[nissannewby]

max of around 15psi without an intercooler an a little higher with one.

What are you guys running for a air filter setup

[nissannewby]

GU airbox is prob the easiest to get in, but there are a couple of aftermarket ones available now. A few blokes have also adapted the square top mounted box to suit, there is a thread around here explaining what they did.

I originally welded on a 3" or 4" pipe to the standard airbox as shown here, that was pre turbo days though = http://www.nissanpatrol.com.au/forums/showthread.php?12130-air-intake-set-up&highlight=pizza+filter+turbo
As Matt mentioned, the easiest way is to run the GU airbox. Very easy to put in and no mods. :)

If you have a look at Rosscos TB42 to TD42 conversion thread you can see how someone modified the original box to suit a larger turbo = http://www.nissanpatrol.com.au/forums/showthread.php?5432-Diesel-conversion-%28TD42-from-TB42%29

I can't seem to find that thread that Matt is talking about but it is here somewhere....I'll try and find it tonight for you.

I have heard of people using a rb25 turbo on a td42. Reason I'm asking is I have one off my rb25 sitting in the garage doing absolutely nothing. Do you guys know much info on this I have found a thread of one on a auto but not a manual
