Importing crate engine from aus ?????

[pruggerdore]

Yeah I had a 350 but look how it just crawled around.
I'm not sure what the transfer box was but it was really well geared.
Having more hp with high gearing just means thing will probably break more as you need to get the engine in the sweet spot for torque to spin tyres.
This requires either re-mapping the ecu for power/torque to be most effective lower down the rev range, or get your gear ratios up to run the motor at the same speed as before, but have slower turning wheels.
This will then let you boot it and get immediate torque to the the wheels, rather than having to get the revs up (and the wheel speeds) before the motor is in the sweet bit of the torque curve

hey steve think you have the numbers for lower gearing to higher gearing around backwards in your mind. high no's = low gearing
low no's = high gearing

3.9 highest hilux ratio
4.8 second to lowest hilux ratio
So yea no proplem with my gearing other than If lower was easily available I would probably try and have it, like most people.
Your 350 with 3.9 high gearing worked as you had bucket loads of torque at idle.

The SC v6 is bugger all taller if any than the Na v6. Computer wise you will need the ecu from the donor car which will need its security stuff removed. You could either use your existing trans or the later one that suits the motor. The later trans is controlled by the engine ecu. I know a bloke with the Sc v6 in a hotrod he sent the ecu and loom to a crowd in the north island and it came back ready to run with only 5-6 wires to hook up.
Which engine do you have the early vn style or the later ecotec?

where did he send the ecu?? Have series 2 vr engine. dont realy want to change trans to the later one as if it dosnt slide up the bighorn transfer case thats another conversion to do. as in would go howie adapter to landcruiser transfer. at least then I could have a pto winch... mmm now theres a thought. as for the s/c motor being taller than ecotec I think not much but a bit taller than vr. measured an ecotec a few days ago and about 40cm taller. so by droping engine 50mm could do it.
thanks for the input guys keeps me thinking

Have a really good look at some pics of the SC engine. The throttle body is at the rear like the early engine and about the same height. basically the sc is the intake manifold as well so it doesn't add much height.
I can find out who did the ecu and loom, I do know it worked out cheaper for him than for us to do the wiring for it at work.

I know how gear ratios work dude, trust me.

My hilux crawled around (slower than walking speed) at idle with 3.9 diffs and 37" tyres.
That has NOTHING to do with how much torque my engine had.
An engine speed matched to gear/transfer/diff ratios is what makes it crawl around at walking speed or needing a foot on the brake to slow it down.
This is why rock crawlers have twin trans/transfer. They don't put super chargers or bigger engines in.

yea had alook at engine pics on trdme in cars and compared them as how far they come up fire wall on cars and yea not a lot in it. on top of throttle cable buterfly I have about 3cm so with an inch bodylift on front end and droping the engine 50mm I reckon Its doable. find details on ecu be great thanks. they have security codeing in them i asume? for the engine to behave pretty sure it needs the original trans to talk too. no doubt deletable if someone clever enough.

what Im saying mate is your hilux runing standard transfer on 3.9 diffs and 37s was far higher geared than my bighorn transfer and 4.8 diffs. gearing mine down further is going to do nothing for my wheelspin speed. yep 3 gearboxs and 2 transfers would be great if I had a rock crawler. I dont. I want to spin wheels faster in mud = need more power. simple

[Weemsy]

I think you're missing the point I'm trying to make mate, so il leave it at that

Good luck with the build & see ya soon

Settle down girls, first off you should have gone with a diesel (ideally an isuzu)
However you didn't, search yellaterra superchargers, they are a bolt of job and sit at the front of the motor, kinda look like a turbo at first but belt driven. You may have the room for it??
3.9 Hilux diff isn't the highest 3.7 from memory is
4.8 isn't 2nd lowest diff either, it's 3rd (5.29 a 5.7)
Look into a cam aswell seen good results
Have you got the standard throttle body? An easy upgrade is the V8 one or even running twin throttle bodies,
If you want me to get stuff I'll be back In Nz later this year

yea rick was getting around to talking to you. supercharger turbo, problem is space. yep will be getting hold of a few engine builders this week. no of hours going in on head work scares me $ wise. just bouncing around ideas at this stage.

Might be worth a call to Bryan Hartley at The Head Shop. He's in Palmerston North and has probably forgotten more about commy V6's than most people know...he'll give you the best advice on what works from his proven builds. Also has years of data on his engine dyno to back it up...
