Outer Limits 4x4 Board

I am in the procees of rebuilding my FJ40 and want to put a different engine in it

My choices were either a

Injected 250 crossflow
Clevo 351 or 302

But i am now leaning towards a holden v6 as it would use less fuel than the other engines

Also i would like to have an auto behind the engine

Just playing around with ideas at the moment but would like to see what the best choice would be

keeping i mind that I am on a bugdet

Injected 4.0l from falcon EF on, cheap as chips, more torque than a commodore V6, and will handle a turbo well

rb30 turbo
rb 25
3.8 litre v6
350 chev
253
308


whats ya buget

i seen 3.8 v6 turboed with 400hp @10psi (10grand later)

351 clevo

go the 250 xflow
i fitted one into my 40 and loved it
you can go a c4 auto and get a adpater from marks for around $900

go straight lpg and you will never get a cheaper 40 to run mine used around 15-20l of lpg per 100kays at 50cpl thats under 10bux per 100kays

4.0L can handle so much once you start decompressing with thicker head gaskets for a turbo it will strecht the timeing chain and course all sorts of problems i have seen a few turbo and supercherged 4.0L and all had problems

Lexus V8

i agree ford 4litres with turbos go well but prone to do heads with alot of revving www.fordmods.com have a look there and see what they do with ford 6cyl motors

commo v6's and lexus v8's are too rev happy for a 40 i recon...

i've experienced pcmans 250xflow setup and it cranks. you won't be dissapointed with aussie v8's either. windsors are cheap as chips

want to keep it toyota a 1fzfe might be an idea, tuff as nails.

mate put a V6 comm into a GQ Shorty, when his 308 blew up ( had the V6 already in the shed)>.. he loved it, plenty of power and HEAPS cheaper to run than the 308..

Well obviously cost is a concern or you wouldn't car about the fuel economy difference in engines. In that case the ford engine will be a cheaper fit. Go the EF engine, not much more to buy than an early Xflow but more power and torque.
Lexus V8 is probably about a five grand fit v's three and a half grand for ya ford If you're doing them yourself.
EF engine has coil pack which isn't affected by water as much as a dizzy on the EL engine.
Have fun.

I don't know about the lexus V8, but the three commodores I had (VR, VS, VT) I thought the engines weren't all that "revable." Sure, they'd spin to the redline, but only because the damn transmission would kick-back too readily. Overtaking on the highway used to suck - the V6 has great mid-range torque, but push the pedal too far, the trans kicks back to 2nd, the engine's screaming but the car's not accelerating well enough to justify the kickdown.

Other than that, I liked the Commodores. The VT could return better than 10l/100km on the highway, at respectable speeds too. Very easy to drive long distances.

Don't know you could say the same about a 40.

supercharged holden V6 or chev V6

Yep, and all the LPG gear is easy to get out of taxis. The commo v6 would not even come close, provided there's room in the engine bay - which there is. It's also a lot more powerful than the old crossflow.

On the other hand if you don't want dual fuel then you're right that the commo v6 will be less thirsty.

Or - if you can get one the right age, then a 350 chev or 351 clevo are obviously going to get you more ponies per dollar than any other option.

Go the V6 - cheap as chips. I would think that the low down torque of the V6 would be equal or better than an old school 302/308.

I"ve got a 250 crossflow engine if you want it with auto box for $200

Yeah, if "equal or better" means half as good.

That commo v6 is not a total dud, but geez it seems to be the most overrated engine in the country. On a good day it will make 300Nm of torque at 3600rpm. That is not "low down torque", that is an engine that needs to rev its tits off before it's any good.

A 308 will get you 340Nm at 2400 rpm. A 350 chev will get you 400Nm at 2800 rpm. An EF Falcon 6 (not even an XR6) will get you 357Nm at 3000rpm and can be gotten just as cheap as a commodore motor.

Then consider the older Ford sixes: 295Nm at 1800 rpm, 305Nm at 2000 rpm, 310Nm at 2300 rpm depending on the model.

This isn't a Holden/Ford thing.

Shame your not down here in mexico, i got an XH (EL) XR6 4.ol sitting on my shed floor i had in an XF till someone bent it

bUICK V6, want to buy one ? i have 2 in the shed i want to get rid of.

leaning towards the ef 6 now

how strong is the auto in them??

thanks for the suggestens

The auto is plenty strong enough but i don't think anyone is making an adaptor from the ford auto to a transfer

cloughy wrote:The auto is plenty strong enough but i don't think anyone is making an adaptor from the ford auto to a transfer

I think you're right on both counts. However you could use a divorced transfer eg. MQ/MK... or alternatively the manual version is just a T5 five-speed, and I am pretty sure you can find a Jeep transfer case that can be mated to it... depending on how different the Jeep T5 is to the Ford T5.

Or I could be completely out of my tree...

He wants an auto,

chimp+tree mmmmmm.

Mud drags @ Battle of the States this year. 2nd and 3rd in the V8 class were two Lexus V8 powered 4Runners on 35" rubber and standard gearing. I know what i'd choose
(1st was a trailered HJ Cruiser ute with something big in it, not sure what but it had two full size radiators!)

ps... Wonder who the 4runners were

Pretty sure the Fj Cruiser had a fully worked 351 Cleveland in it (or something like that)...he'd put a lot of $$$ in it but.....

Funny that both 2nd and 3rd place getters with the Lexus V8's both blew there front diffs doing the drag as well.....piece of sh!t IFS.......atleast one of us is fixing that properly but

And they sounded the part too. Might know of another Lexus that might be at the drags next year too

see chimpboys post on the torque curves... hard facts don't lie.

i'm not knocking the lexus option, but for the $$$ you can get better bang for bucks.

and add the fact that a 2f makes 275NM at 1800rpm... which is called low down grunt

265 HEMI now that is torque
