For the work, that conversion isnt enough extra power to warrant the cost, or time.

agree on power.

Im putting a 5.0L on a gq chassis and already wishing id spent the cash on a GenIII.


$1500 for motor and auto
$1000 for adapter
$____ for wiring ( havent gotten to that stage yet)

Cost isnt that bad IMO, when a gen 3 and auto is selling here for 5K

yeah im converting from a 3ltr petrol which iv turbod and played with for 2 years now and sik of it to many head aches i put a 253 in my old hilux and it took a caining so im keen to get an 8 back

go the blown 454

Don't waste your time on it talk to killalux on here about a gen3

i'm looking at doing the ford conversion at the end of the year.

how much power isn't enough ??

engine can be had for $2000 with loom and all the bits.
$1600 for head and cam and throttle body.
and BAM - 350hp !!

is that enough power ??

should cost about 5k and 2 weeks work.

worth doing ??

I personally know 2 guys who have done the 5L conversions, one in a GQ and one in an 80 series, and both are pretty disapointed. Why?

in order to get the torque out of the engines they need to rev them about 3000rpm, now even in low range thats too fast, yes its nice to do 4 wheel wheelspins but thats about all the 5L is good for, i can get more places with my TD42 N/A at a confortable and traction keeping speed than the 5L GQ and 80 series can, i don't need to rev the guts out of it, can't wait to turbo it.

a gen3 is no diffent you have to rev it to get it go ive don both conversions to a gq and i like the 5l better then the gen3 but my 5l was a 355 stroker pumpinf 400hp out of it but not ever one has the $$$$ to spend.http:/

hmmm thanks for the feed back guys im still uncertin what to do the 3ltr has to go i no i made the mistake from day one but iv built the truck up and gone to far to sell it now and buy somethin else what to do what to do

If your after low rpm power look no further then a
big block ford or Chev

I replaced a 2.8t diesel for a 7.4 LPG chev which does
the job quiet well moving a gq on 35's

You need the correct cam in order for low engine torque in the 5.0l, Dave Goss from Gossies Dyno Tuning at Morriset found a cam almost by mistake that gives max torque at 1500 odd all the way through to 4-5grand.
Also shaved 90thou off the heads to achieve this and its been in his dyna 4wd for 13 odd years without troubles!
My 5.0l will be getting this cam and head work after tax when i have some money to throw at it


There's lots of hidden costs with everything, gen 3 will be more expensive than a 5.0l conversion.
Heads wil need $$ spent if running on gas in both engines, 5.0l iron
heads wont melt into a pile of metal after the'v been hot either

I know a guy who went from a 5.0l to a 355 stroker(with mods) in the same truck and it hauled over a gen3(with mods)

But in the end it comes down to money...and what you get talked into!
I wished i had gone the 355 stroker route with cam and inlet mods with gas injection but time wasnt on my side and had to be done quickly...

I live with that choice though and i do still enjoy driving it!

Work out your budget then go from there, and if it's 8 grand allow for 11-12k cos costs will pop up unexpectably
But go for cubes

Cost should be the last consideration when doing a conversion, they are all alot of work, and if you cant afford what you want, be patient and save longer, but dont choose what you can afford now, if its not what you want, or you will spend the whole time you drive it wishing you did what you wanted!

A big block on LPG in a 4wd is awesome, for the same amount of work, and afew extra $.

thanks alot guys i was thinking the same thing with the 5.0 having cast heads gotta be a good thing i plan on getting the standard motor in and doing engine work down the track just so i no what it goes like and work up from there as to how i want it to proform. Money isn't really a problem with it but my opinion on the 5.7 is that there cost for the conversion is way to much as iv played with alot of 5.0s in my time and you can really get them going well enough for what i want to do. Thanks for your feed back guys its been a huge help

If I did it again I would go a LS2 every day of the week. 400hp ( bolt some l76 heads on with a slightly bigger cam and you will have 500hp) out of the crate, you cant can't go wrong. And with all wiring adapters and PCM tuners, it makes it a whole lot easer these days. You will still need to part with 10k I would think, if you do it your self.

wow

yeah from what iv heard the ls1 is worth about 10k for the conversion it would be nice just for what i wanna do i cant justify it even tho it would crack

Why just do a conversion (that seems to have MORE than a few detractors), when you seem stuck to badget?

ANYTHING is going to going to have more power than an RB30, and less hassles than an RB30 turbo.

Why not just get a TB42/42E/45E or TB48E? Nissan stock, less conversion dramas!!

If you can't afford $10-12k for GOOD conversion (LS1, even though my vote would be for an L76/L98 6L), why do a swap with more bad outcome than good??

V8 conversion . . What about engineering costs and increase in insurance?

gday bigbluemav

yeah i looked into doing the 4.2 conversion but converting it from a petrol i really need a whole doner car to swap all the gear over and from experiance all my mates have had to turbo there 4.2s for extra power and realisticly i should sell me truck and buy one with a 4.2 in it but iv got mine set up how i want it just needs a bit more power. i can see where your coming from but keeping in mind im not using it for 4wd comps or anything providing i can push 37s at 110k an hour with out to much trouble and have bit of talk when i need it ill be happy

Hi Kop

A carbed TB42 would be an easy swap, no electonics etc. Cheap to buy (and/or rebuild too!!). If you were thinking about a V8 swap, a TB45E would be the same amount of hassle (electronics etc), but you could get nearly ALL the bits from wreckers for cheaper than the bits you'd need to buy from specialist mobs.

Don't forget gearing too, put 4.6's (instead of the std 4.3's) for a bit more go. ANd for offroad, lockers and t/case gears. Better way to spend $$ than V8 swap.

ah ok yeah thanks for that i havent really looked into that option maybe ill do that see whats avalible ect

don t go tb 42 carby motor they are heavey on fuel chew through ignition points and dont go hard enough to convert to
