removing commy v6 for 1kz in ln106 hilux

[matt303]

hey guys, so im planning on removing the commy v6 out of my hilux and putting in a 1kz. I want todo south island trip and cant afford to run the commy motor. so if anyone has a 1kz motor and everything to run it for good price would be awesome and i will try make it fit to my g56 supra gbox and any other info would be awesome. cheers guys

for the amount it would cost to put a 1kz motor in wouldn't you be able to do the south island trip.?

your 5.29 trail creeper diffs is probably your biggest killer as you'd be doing quite high revs even on 36's and churning through the gas at 100km/h

x2 the commy would cost a shitload less on gas to do a round trip than it would cost to shove one of those head cracking engines in your lux

keep the 3.8, just keep off the go faster pedal

x4 seems a little backwards logic to put a $2000+ engine swap instead of paying some extra coins for gas for a road trip, unless its like thirsty beyond belief but i couldn't imagine a commy being all that bad surely not 2k difference in a gas bill for a road trip round the south island.

Just my thoughts tho

Plus a new fuel system, cert and RUCs

g52 box wont bolt up to the 1kz motors only the r series so budget on at least another 500 for a surf gearbox to go behind the motor

[J_Dub]

Yea mate, say you do 2000ks.
The 1kz mite do 500ks a tank and the comy 400ks, that's only 1 extra tank of gas, taking into account difference in price your only saving a couple hundy $$$.

You sure its worth the hassle?

[matt303]

cheers for replies guys, im only getting 200-250km to a tank if im lucky and im now running a supra gbox and it sits on about 2500rpm at 100kmh, so not over reving etc and that is driving with very light foot, i have installed o2 sensor and tried eco memcal etc nothing to improve gas so any info would be awesome. cheers

buy a cheap starlet or barina runabout and leave the lux at home in the driveway for weekend playtime you must be ripping those 36" simexes to pieces running around on the road all the time

[J_Dub]

There is something with the comy 6s that makes them drink gas if its not wired right, for the life of me can't think what its called

[matt303]

oh yeah, looks like i will have to do some research into that one. I have a work van as a run around so not too bad.

Thats the vss vehicle speed sensor your thinking of it runs a default rich fuel map when it doesn't know how fast your going. Depends on how tuned your memcal is.

So Ashohman just beat me to it (how nice of ORE to let me know before I post and look like a retard). Marks adaptors sell a VSS that plugs into the toy t-case and can give the needed ECU input. About $300 from memory, but I never bothered.

I used to get 5 or 6 km's per litre (4wd and open road, usually not to much urban). That was with an exo and 35 simex.

Have you tried cruising at 90 kph? (I didn't) your drag coefficient drops about 20% by dropping that 10 kph. Might be worth while on a big road trip.

[Ashohman]

Also make sure your o2 sensors are working properly too no exhaust leaks before sensor otherwise it will richen up the fuel also.
