G'day mate,

Just letting you know the 3rz is a very worthwhile conversion! I've just converted my 4Runner from a 22R to the 3rz, nearly all finished now, just need to rig up V6 handbrake and then off to engineer to get it all legal and shit. All up, after engineering, it will have set me back around 4g, thats including a 2.5in mandrel bent exhaust front to back with high flow cat, brand spankers clutch, intake piping... basically everything needed. I did all the work myself with help from a few mates to get the engine in. Oh, that price also included a body lift to give me clearances around the engine.

Air intake, all I did was get a 180 degree mandrel bent 2.5in pipe, and swung it back around to the passenger side to the standard airbox, easy and looks reasonably factory.

Tacho I cant get to work, and it sounds like its a common problem. Funnily enough, I found this thread as I was about to post up asking how to get the tacho working! Well, looks like I'll keep hacking at it till its working.

As for fuel, I used a tank from a V6 4runner with the standard fuel pump, and it seems fine.

Anyway, if you need any info, just ask, I think I found all the possible PITA problems when doin it in mine!

Good luck mate!

Simo

thanks for that simo all appreciated m8! i will if i get stuck, cheers!!

another bit of useless info on my 3rz journeys, the intake and exhaust manifolds arent portmatched, the ports in the head can be honed out 2mm or so, more power for a bit of work.

and if you need any parts for the motor let me know i have 2 3rz's of spare parts, sensors ecu's wiring , coilpacks etc.

ok cheers m8. might be up for a box now too LOL after this weekends episode

hi i have also been thinking of this conversion but was wondering what is the life of a 3rz as i will possibly be able to get hold of a 3rz cheap but it has 227000kms on it

thanks for any help
dave

they are supposedly getting a fair few k's outa them but hey, ya mayes well do it right and get a low k's one in the beggining you would hate to get it all done wouldnt ya and find out its its last leg.. my 2c.

Just a quick update... got the tacho working on my conversion this weekend. Simply replaced the 33k resistor on the tacho circuit board with a 10k one, similar to the mod they use in the US, and it works fine. This is using a 22R cluster tho, not sure about the diesel clustors.

ah cheers m8.. not long till this swap is under way so just playing the waiting game now.. any body have any diesel to 3r tacho hints?

Post by **want33s** » Mon Jun 30, 2008 6:24 pm

I think your best bet to get a working tacho might be to fit a petrol dash.
Prob be the easiest way if its as simple as changing a resistor.
If I were doing this conversion I'd fit a complete wiring loom from a petrol lux. Then the ECU and everything else will just plug in.

Post by **smaddock** » Tue Jul 01, 2008 5:04 pm

Good luck trying to use the complete loom. I had a look at one at a wreckers, and it looks like the whole bloody body loom is integrated together, far too difficult. All I did was run an uncut engine loom to the ECU, then wire up less than 10 seperate wires from the battery/relays and dash.

hi smaddock do you have a qquick wiring diagram that you could pm me.. cheers

Post by **chunderlicious** » Tue Jul 01, 2008 8:19 pm

get intouch with killalux. his wiring is awsome. well worth paying for. so neat and hell do it how you want it. just PM him and he might be able to help you.

Thanks sloshy...

Thats exactly the info I worked off to do mine. Easy enough to follow.

Post by **Lux_89** » Thu Jul 10, 2008 7:12 pm

hey guys.. lil update.. I BROUGHT A MOTOR

will be starting the conversion next week so stay tuned.. pickin it up saturday morn, so let the fun begin!

Post by **smaddock** » Fri Jul 11, 2008 9:51 am

Ahhh very nice... good luck with the conversion mate! Hope all goes smooth

Post by **Lux_89** » Fri Jul 11, 2008 8:19 pm

cheers man appreciate it as ill need it lol

Post by **Lux_89** » Sat Jul 12, 2008 1:35 pm

ok have the motor now. Build will be going ahead in my members thread so keep an eye on that if interested. Cheers

Post by **Lux_89** » Sun Jul 13, 2008 8:51 pm

hey guys, does anyone no if a tank from a v6 runner will fit where the diesel ones sit cuz the 3rz tank is too farkin long. and basically i have no idea about fuel pumps and all that crap coming from a diesel... Cheers.

Post by **smaddock** » Thu Jul 17, 2008 9:11 am

On mine, I used the v6 tank and in-tank pump. It bolted straight in place of the original petrol engine, but not sure if it will bolt in place of the diesel tank... I would imagine they would though ??

Post by **Sic Lux** » Thu Jul 17, 2008 6:29 pm

Was thinking much the same

Post by **Lux_89** » Thu Jul 17, 2008 7:32 pm

too late guys... i have a lift pump and high pressure pump for the diesel tank

Does anyone have any feedback on the 3RZ with regards to water and mud ingress?

they are typical toyota 4wd based engine, all the right plugs and connectors that are pretty water tight. we have suck it in mud twice at TT now and have never had prob. got a gut full of water at woodpecker. and it doesn't seem to hurt them. we only run a pod filter. AFM got covered in mud, so i just soaked it in carb cleaner and lightly brushed the mud off the hot wire and it still work fine!!

This does seem to be the sensible option, only 15kw less than the Commodore engine and 50nm of torque less without the associated headaches of making something fit in a hole is wasn't designed to go in.

So a 2wd bell housing works as a bolt in, wiring seems reasonably straight forward. I assume my 3L diesel radiator will work?

Post by **1MadEngineer** » Wed Aug 06, 2008 1:07 pm

one of the best things is that they don't overheat, like nearly all v6 conversions do!

Post by **Lux_89** » Wed Aug 06, 2008 3:51 pm

hell yeh... diesel rad is the best due to it being bigger than stock. Wiring is easier than i thought once i saw rory doing mine... uses diesel engine mounts, just have to grind the locater pins down a tad in diameter. Wack a cheap ass pod on it.. bit of vac hose to run over to the old booster with the one way valve.. dont even have to move your battery however it would be better swapping it to the other side.. fuk the gas i say. AND the best part is i recon mine, that is 3rz, 30inch tires, g52.. i recon will blow the doors off my mates auto commo conv lux. As soon as mine is engineered (tomorrow) ill be giving him a run. I did notice mine really picks up and goes after 3 grand in road driving situation, my mates say beacuse of the twin cam design? but ive got 4.7's so its towie as fuk in low n thats all that really matters
