Has anyone got info, links, pictures etc. of modified 3.0 motors please?
I'm sure the lump is not running at its potential maximum power, as with all vehicles, so I'm wondering if anyone has actually found a good way of getting serious BHP and Torque gains Shocked

A simple remap/superchip type of plug in is quoted as giving +30 BHP and +35 lbft, but I want more!
The first area I'm looking at is the turbo: its pretty small for a 3.0 16V twin cam, I think a much bigger one will really improve things? Wouldn't want to go too far though or the motor would lose too much low down torque/power, something I definately don't want to do.....any ideas welcome! Laughing

So - most unreliable money pit ever owned - is going to be chipped for more power ? Shocked

Oh yes! I don't give up very easily....I'm just buying another Frontera for daily use Laughing

I've long since given up on it being a reliable daily driver, so might as well see what it can do!

Oh and also, I'm not going to chip it, remapping would be the only way to go Wink

Massive intercooler, some head work and compound turbos?

Hmmm, good thinking!
Not sure what can be done with the head though, theres no room for big valves, and the head itself is more air than metal! maybe a bit of porting, but not sure if it will do any good on a dirty diesel? Laughing

gary has a 'tunit' box (i think it's one of those) fitted to his 3ltr ...... i've looked into a propper re-map but at about £400 it can wait a while.....according to figures it gives quite an increase in power/torque

standard 3ltr 156bhp
245lb/ft torque

after re-map
about 200 bhp
and 300lb/ft torque Very Happy

I have a tunit box on mine, noticeable difference in performance and pulls well on 33's. Free flow exhaust with no cat also. I thought about doing something with the egr and thought about increasing boost but it runs well as it is and I don't wanna upset it too much!

I've also seen the Tunit, looks good I agree. Just think that one area on these engines that needs proper careful work is the injection side of things, and just increasing the fuel pressure isn't perfect! I've got a Turbotune unit on my Master van and its superb, really does bump up the midrange grunt!

Forgot! I've also got a complete Powerflow stainless system to go on, and a spare front pipe/cat that will be getting 'altered' a bit!

If you want power you will need to up the fueling, by a chip/remap of some sort. Pressure will be increased
If your gonna bolt a bigger turbo etc on you will need a map to suit, you'll be into custom mapping if you can find someone to do it. It's not a commonly tuned engine beyond off the shelf products.

I think you need a v8 of some sort not a 3.0 trooper!!!

don't think i'd push the 3ltr any further than a normal remap as it's unknown territory Confused

i think the 3ltr can handle the 200bhp re-map and think that would be quite sufficient for me as it's the torque part that would be the most usefull Wink
