Outer Limits 4x4 Board

If you go the RB route, check out my wiring post in Patrol4x4 under DIY. Both V8 and RB have merit but I reckon the RB would be happening sooner and I couldnt see it costing more than 2k if ya did the work yourself. The non turbo RBs are perfectly capable of handling a fair whack of boost with just ...

what exactly are you dyno tuning, Its running factory management??? the wildest thing you could do is screw in a bit more base timing and that can be done in your driveway.
Dont get talked into wasting money.

best off test driving each. I went with the manual simply coz it went well and as Feral said the manuals are very tough. The auto cost a bloody fortune to rebuild should they need it which most do after years of lugging nearly 2.5tonnes in overdrive. The autos were never equiped with adequate ...

what they say is correct. Your current injectors are not reaching 100% duty cycle anyway so you certainly dont need bigger ones. A decent after market ecu/loom/tune will set you back 2K plus dyno time for very little gain. If you go this route youd atleast want higher comp and suitable cam to get ...

head gasket failure or cracked head. Mine had same symptoms but like you said ran fine when up to temp.
I went with a brand new head had it sorted for LPG. It wasnt cheap but a very straight forward job.
around 2grand from memory and went with a VRS gasket kit with NEW head bolts.

there is only a handful of 2.8's that make it past 200k, there are people out there that defend them but I have helped pull a few out for mates and unfortunately the probs they face are usually expensive to fix. IMO they are let down by their cooling systems which get neglected over the years. The ...

It will be interesting when all these converted hybrid ricer GU's end up on the forsale section and the folks end up going back to 4.2 diesels or big petrols. I would suggest driving one before doing the conversion, IMO the RB30 was only just barable when turboed in a GQ and useless off road. It ...

they are just as hard to get out as the manual and since most mechanics charge 1300AUS to do a clutch im guessing the clutch the kit is around 700 so that leaves 600 in labour.
I couldnt see anyone getting one out in under 3 hours, they are big and heavy and require a fair bit of accessory removal.

Id be checking your AFM it sounds like its goint into a limp mode. No need to dyno tune a TB42e, there is nothing that can be done that the computer isnt already doing, anyone that tells you otherwise is ripping you off. They are a pretty basic engine that obey some fairly basic inputs not much can ...

appologies, I assumed it was an RB30. I dont know about needing boost in low range......... VG30 turbo is very similar to VL t3, I have had one and believe it is a far better and more responsive turbo however they are getting long in the tooth and I dont believe you can rebuild the CHRA or core, so ...

Personally I would stick with the genuine nissan head gasket, new bolts and have the combustion chambers relieved ever so slightly, standard comp ratio is pretty generous anyway for turbocharging. Failing that when you rebuild get the block O ringed. I have not seen too many success stories with ...

If you have never rebuilt a turbo save yourself the headache and get it done, its got to be balanced anyway so you wont be able to do it yourself anyway. The kits are 70-90$ on ebay. BTW the standard turbo was terrible on my GQ and I always thought it would be, it boosted way to low in rpm. Not a ...

no way i'd be paying over a grand for one, they have all done over 200k now. A brand spanker or reco you'd be looking at 5k. And yeah a mechainic will charge abit to find one (with warranty) and labour to fit. Dont see too many for sale second hand though. Whats wrong with yours, they are a piece of ...

If a question like this needs to be asked obviously little reseach has been done and even less time spent under a gq.

Ferral, you pull the RB30ET out did you? Sounds like a promising conversion with the 4.8, suss out keeping the standard ecu if you still have it, you got to weigh up whether its worth the expense upgrading particulary if you are keeping it nat asp chasing just a few kw out of standard injectors and ...

Well thats it then, Im happy enough to get one between now and chrissy. Let me know if anyone has one for sale. Im going to Tassie next week with work and there is one with 114k but asking 24000, WTF. Im happy to look at it and in two months when it hasnt sold i will put the word on. Were the 4.5 ...

I have never really payed too much attention to the petrol GU's but I have been without a patrol now for a couple of years. I do miss my TB42 shorty and also my RB30 GQ turbo. The GU petrol 6's are getting pretty damn cheep but whilst I am searching all I can I cant seen to find out what sort of ...

gday, im getting myself a fourby again, gone is the lifted chopped and grubby GQ shorty. Wife says i can get somthing niceish. Well the jacks look like surpringly good value. I imagine the Isuzu is a fairly good motor, im looking at getting one with no more than 200K. What sort of life do these ...

Gday, time for me to get a fourby again, The lifted/chopped/flexed shorty GQ is long gone and I am looking towards a post 98 Grand Vitara LWB V6. I intend to do mostly touring and towing my 600kg Quintrex around, with some trips to fraser down the track. Are the engines fairly robust, and is there ...

Hitachi are mitsibushi and Nissan bought Garrret so be wary if you are getting a hitachi it may not be a direct fit. Also as mentioned Hi-flow means many things, a good dyno tune is a must if fitting an unknown turbo. You really cant go wrong with a rebuilt standard unit, especially if you want ...

yep everything is interchangable, as in everything from a 3.0L GQ will bolt into a shorty. You really only need engine/box/crossmember. Your diffs will be too tall (ratio) but can live with it if turboed. I turboed my LWB rb30 and hope to do the same conversion to my SWB but the TB just wont die ...

Mild steel is fine for pipework, some of my old cars are still getting about 12 years later on the same engines, turbo/cooler combos. The internal surfaces do get coated with a greasy film as the turbo seals will let some oily mist thru and as will the PCV if connected. If in doubt pull a oil soaked ...

the turbine wheel acts like a muffler in the turbo, still without muffler will be fairly loud and only give you minimal extra grunt. Also muffler does nothing for emissions so yes its legal to run without one, noise limit is 93 db from memory but im if you do any serious road kays the noise drives ...

why wouldnt you want to turbo it, It cost me just on 2K to turbo and intercool my old RB Patrol and had 155kw at the rears with 33's. Way better on fuel and so dam quick. All second hand nissan bits and pieces. For those sort of dollars youd be lucky to get a cam and exhuaust. I have all the wiring ...

I have 33's on my shorty, they are BFGoodrich all terrains but only 10.5wide. they are wearing fantastic even after 50 000k's they were on the car when it had no lift and saggy springs, so they clear just fine with my 2inch oldman emu's. The other bonus of these NARROW 33's is that they legally and ...

I think the cam is gear driven, but i had some wierd noises turned out to be one slightly bent pushrod. Torque converter can come loose on TBs also but that makes a chuff, chuff type noise. Hope you get it sorted.

your mad to get rid of the RB-30 A-Ferral im planning on putting one into my SWB the TB is a slug. I Had a basic turbo setup in my LWB on 33's went grouse, especially on the open road. If anyone wants the wiring diagrams to fit the injection and turbo I drew them up PM me. I had it turbo'd and ...

im also in kilsyth and just sorted my TB42 head out. 200,000 kms on gas was enough for mine to crack front to rear. Speak to Orger engines in bayswater, they have done sooooo many of these heads, will tell you strait away if yours is repairable, unfortunately even with a repair you wont save your ...

couldnt tell ya
im still waiting for my scuffed up old ST's to wear out, 80,000 and still okay. Love em

If they are both 6's they will be the same heat range.
Be carefull going a colder plug they can be temperemental at idle. I went back to standard BPRES6 in my 3.0L turbo LWB and they were fine even on 12psi. Maybe close your gaps down a little.
