GQ/GU- Y60-Y61 - TD42/T/i Pumps 10/11..12mm?

[PeeBee]

Whats the difference between the T and Ti Mark?

The ‘i’ is intercooler I believe mate and also their pumps have more elecy bits to puters I think. We definitely do need an intercooler on the old bus but thought if it was a 10mm pump currently then maybe also needed to go 11mm without the extra elecy bits?

I reckon yours will be an 11mm mate so if you get an intercooler and a good tune you should have awesome results.

From what I know all factory turbo motors have the 11mm pump.

You could be right mate. I'm sure I was told otherwise though, but it was a few years back when I was first doing the conversion.

Half an hour found McGoogling the Nissan pump number they VIN gave me above and my head is starting to hurt :-) ! Only so far finding Bosch & Zexel part numbers for “plunger” sizes after O-TJ-O ‘s kind lead. The Zexel plunger number did appear to start with 11F but I’m only guessing there?

If you're after the pump upgrade mate you want to talk to someone like UFI in WA or some other reputable pump builder which there's a few around now i think. They do more than just put a bigger plunger in apparently. They set it up so the fuel comes on in a nice curve. I told them what patrol I had and they told me what I needed and had it out to me in a week.

What they did tell me is that they could build a good 200hp pump in 11mm a bit cheaper than a 12mm.

Cheers heaps Mate!
Only for now trying to cheaply squeeze a whisker more out of it and most importantly lower the EGT’s for longevity whilst heavier hauling forthcoming. We currently just run a Redarc gauge/alarm and drop a cog or two when towing 2.5Tish up decent highway hills, becoming annoying though as more power is there waiting!
More McGoogling just now just found a possible telltale that 11mm is stock for all GU’s they’ve apparently worded for GQTD42 older goldies upgrades?

Probably best just to get my arse into gear and intercooler the old bus ASAP :-)
