After more power 4.2 carby dual fuel

[Bigrig]

OK then. start again.
After more power from 4.2 carby lwb 4x4 on dual fuel, this is a highway cruiser tow vehicle, daily driver.
Has all the usual mode so far.
Extractors, 2 1/2 exh system, pertronic, iridium plugs, morey's oil drip system.
2" raised and poly bag inside rear, caster correction etc.

After a power increase to tow so where not that 4x4 that hold everyone up at the first sign of a hill.
So approx 30% increase in power could be on the money.

After advise from someone that know's on what can be used to achieve a reliable engine for this sort of gain in power and the added torque.
Think v8 is over kill on cost and that this sort of power gain can be easy to achieve with efi cam and maybe turbo. And not interested in diesel.
$$$$ are not the question here I'm after the info.
Just to quote cam, injection, turbo , isn't a answer.This is obvious.
What has been done and or can be used, and parts spec's to achieve this sort of gain with reliability.
After the complete story for around 30% increase in power and the associated torque that goes along with it.

Cheers

I think whatever way you'll go, you'd end up with at least 30% power increase with the ability to have more (i.e. low boost turbo = 30%; higher boosting = ??% possibly up to and over 100% even). A basic turbo kit (chinese ones which is what I have) and gear will probably be a decent start if you're only looking for low to mild boost (5-7 pounds) to get rid of the rigs fear of anything slightly uphill. Adding an intercooler to it is absolutely not necessary at that sort of boost, so that is a major cost saving straight away - turbo/wastegate/actuator etc; manifold, dump pipe, sump modification for oil line, etc I reckon you could get your hands on for under a couple of thousand at the very worst. For fitment of that to the rig, you should only be looking at the same (or considerably less) through a decent mechanic and you have the desired outcome for a fairly economical price - with the ability to kick it up in the future if you should decide to do so.

Brands etc are not something I know, but that would be the place to start - basic kits ... QuickSpool do a proper Garrett bolt on kit for the Patrols starting at $3999 and they achieve around 480hp!!!

Thanks.
This is the exactly sort of response I'm after a brand name, can now research for info my self, good stuff
Chinese copy your talking about, is a kit or something you knocked up?.

Bought it as is mate - I'll drag out the details for it ...
I attached a Ford XR6 turbo to it also

Ill throw this in Youve bought a carb dual fuel TB42 you want more power and your taking 12 GRAND on a motor ???
I mentioned 4K as to get the same power from a 4.2 straight six poxy carbed engine the V8 will be all over you for minimal $$$
Maybe you should explain yourself a touch better
What exact budget are we really talking about ???
12 K on a fully rebuild all new parts carbed TB42 for a 30% if that gain, reliable, more efficient , nah the cogs arent lining up
12K if thats your budget on an engine alone, an LS1 conversdion will be had for cheaper and still have you all across the field
Before your hang sh*t on me for this , look and read theres plenty who DONT rebuild there TB42 , because its cheaper to go the V8 route, more power and the same economy
Please dont bang on about 2nd hand bits , your talking a 12K engine in an old carb TB42 rig, that no doubt the rest of it wont be upto the task
12K on a TB42 for a 30% power increase, im glad your doin it

Anywho, ill sit back and enjoy the fruits of your labour
Keep me and others informed , im keen to see such a fine piece of machinery art

Mate I can only say 1 thing, read original title.
in a nut shell.
"Improve 4.2 petrol". not convert to v8.

cheers.

OK,ill bite
Whats your BUDGET ???

Lets look 12K
Brand new crate engines
Brand new 502 CUIN ($11,950)
502 HP @5200 rpm
567 ft lb torque

350 chev ($6950)
388 hp
385 ft lb torque

Ford boss 363 cu in ($12500)
500 hp

eagleautoparts.com.au

These dont however include conversion kits,but that cost can depend on what you exactly buy and how knowledgable people are and what they can or cant do

A TB42 will never get reliable power anywhere near those about for 12 K

Realistic budget

So,ill bite , whats your realistic budget ???

Lets look at what 12 K gets in a "New chev crate engine"

502 cuin ($13750)
502 HP @ 5100 rpm
566 FT/LBS torque @ 3200 rpm

350 chev ($6950)
385 HP @ 6000 rpm
385 FT/LBS torque @ 4000 rpm

eagleautoparts.com.au

12K on a TB42,looking at the above , never ever even think of it

So whats your realistic budget ???
Are you rebuilding said engine or looking for bolt on mods,for a second hand engine ???

Good post mate - only thing I'd add is I've spent under $12k on mine and with 7.5 lb of boost, I'm getting 191 HP and 514nm at the rears on 33's (posted the dyno results on my build thread last week). When I put the electronic boost control on, and up it to 12 lb (decompressed engine also for that amount) I'll be looking at something more like 280-300HP and 800nm at the rear wheels ... I wouldn't get that from an LS2 6.0 ltr that I looked into ($22000 fitted, crate motor and all adapters, etc).

That all said, you're spot on the money though with the other information. For around $10,000 you can turn the TB42 into something that pulls like a steam train ... I know of no TD42 (and no TB42 personally, although I've seen them on YouTube) that could match it with mine now - they're obviously out there, and have probably done similar and have the same thoughts and opinions as me on some aspects of what I'm writing here.

For anyone doing it though, I have three words for you ... preparation, preparation, and preparation!! Prepare for hurdles (moreso that increase the time off the road than the cost), prepare for problems with other components/wiring as you start fiddling with items that haven't been touched for 10 years and are temperamental (decide to fail as everything around them gets touched - my starter motor, my air conditioning, my dizzy module, my coil, etc, etc), and prepare for emotional ups and downs IF it doesn't follow the plan to the letter ... BUT, prepare to have a permanent grin on your dial 24x7 when it finally comes off the rack!!

i was wondering how long it would take for you to weigh in big! lol. After reading your build thread, Im with you mate.....Build the TB42. Im not a fan of LS1's. The standard TB42 i have has got 415,000kms on the same bottom end and going strong!
Build the TB42!

Thanks mate ... Corey is spot on with what he's suggesting though - that's the beauty I guess, when you're talking that much money, there's a good array of options to turn the truck into a fire breather (not what I wanted as such, the torque was what I was after). The thing that put me off the engine swap was the cost and fitment of the adaption kits ...
