Camshaft, head work, raising compression, fuel injection etc. Speed costs money - how fast do you want to go?

Hi Tony.
after something better.
the amount of torque these have seems fairly ok but getting there is like watching paint dry.
was wondering what others are doing?.
would like v8 but can't justify those $$ and probable insurance problems.

Ok who's doing engine reco / rebuild for more power for the street?.
Or can I buy the parts and do it myself?.

Then don't waist a cent on the one you have & just put a TD42t in it.... It will probably work out cheaper cost wise. last heaps longer, have the power your looking for & be much better on fuel than a worked TB42 as well.

I've got a TB42 myself but after being in a TD42t I want one, so guess who'll be on the hunt himself later this year???....lol

Thanks, but no thanks, don't agree.
I bought petrol on purpose, just want to get a few more herbs out.

I've recently turbo'd my petrol (well LPG originally, about to be fully petrol again) and even with a small turbo, the power output is more than noticeable - untuned, with the truck having issues and because I'm an idiot mainly (lol), decided to test it out against a monkey in a Audi A6 that was sitting on my rear down a road near me - breaks into two lanes as you near traffic lights, but back into single lane about 50m the other side of the lights (you know the type, quality govt infrastructure!!). Anyways, he pulled out at the double lanes, and pulled up beside me - needless to say, I gave intent that I was going to make things difficult to which the toffee would not have given a second thought due to him being in an A6 and this clown beside him being in a 2.6 tonne patrol ...

Long story short, he needed about another 40-50 metres of parking lane after it went back into a single lane to do the patrol !!! Surprise of his life no doubt!!!

My point is they respond well to a turbo and pull strong ...

Having done what I've done, I wouldn't go through it again and would go straight for a bolt on kit - suss out Will Tobin's website (www.quickspool.com.au) as he does patrol specific kits ... not saying go with his necessarily, but will give you ideas ...

Good luck!!!

My GQ TB42 EFI is 100% stock and theres no way itll get dusted by a 120Y and i dont sit around waiting for paint to dry, for a stock lump it holds its own,and dont think for a sec when the minister drives "Öh a sheila in a 4by thisll be easy " she takes no prisoners
From what ive heard its hard to tune and run both dual fuel and get the max power from both , its either one or the other
If it does seem like that 120Y has you dusted , maybe a full engine diagnosis is in order

Airflow might be restricted by the lpg mixer depending on wich type it is running.
I had a few tb42's years ago and messed with the secondary on the carb so it opened manually.
Changed the timing advance and fitted pertronix ignition with the extended rotor.

120y is a figure of speech, we all know there slow.
I guess you read post wondering how to get more power outta your's also.
My other car is a GTR skyline, you know the little Nissan straight 6, that kicked v8 arse all over the mountain, so I guess I'm after a bit more performance.
Seeing as this Mav is mainly a highway cruise and occasional tow vehicle and not a mud pony.
I was thinking of e/swap to efi and turbo, I'm simply trying to find out what else out there works, and to just install efi ,sorry this isn't enough, for my taste, especially when towing.
