I'm debating wether to install a gas injection system into my 4.2 turbo diesel Patrol, but am a bit weary about it. Would I be better to install an intercooler instead as they end up about the same cost. Any advice from anyone who has fitted either would be greatly appreciated.

Hi Matthew, it's a '01 TD42T Patrol wagon with factory turbo, the only mods it has had is a larger dump pipe and 2 1/2 in exhaust, which has improved the turbo lag, but since I've put the 33in tyres on it's a bit wanting in the hills. I do approx 600k per week to work and back and a bit of playing on the weekends

Ok

First thing you need to do is mod the turbo.by that i mean you need to let the engine breathe before you try and make any further performance gains.

There are a lot of options around,what state are you in.

You can buy a air to water intercooler kit from $1131 depending on barrel size...try this site www.tweakit.net/shop/product
I think that would be a bit cheaper than a gas injection system, but it would not do very much for economy, light on the right foot may be. But great if you want to get more hp, adjusting the pump and boost etc.

Hi Trumper, I am surprised it doesn't have an IC. The trucking industry apparently are jumping into diesel/gas. Some are saving around $1500/month. Private use only, you would need to be doing big Ks or wedded to your vehicle - never to part I would think. 1 - intercooler ..2 diesel/gas IMHO....:))...cheers,

Hi
I went intercooler way. Very happy. I tow a 23 ft van and now dont change gears as much. With out van just like car around town. Better fuel usage.I do have a 3" system which also helped. Dyno readings 26% increase in power. Costed $2000 ,12 mths ago Best money spent on exact same patrol as you

Thanks Peter,
It seems to be the way to go, I'll put a snorkel on then the intercooler and see how I go. I'd like to hear from a couple of people who have had the gas injection for a year or so before I put it on my pride and joy, it could end up being an expensive mistake.

Trumpa, diesel gas before an I/C. I/C work, but for better fuel economy, diesel gas is the go, as long as you don't use the right foot all the time with the new found power.
