Got the go ahead from SWMBO to do a V8 conversion on the Pootrol I love that woman!! I'm currently trying to get my hands on a 4.5 litre Nissan V8...... and i'm researching the 5.0 litre Commonwhore engine..... i decided to also look into a Chev diesel..... i had a bit of a look around, can't find a lot on prices for engines. Any ideas what a half decent 6.5 NA goes for? The Nissan Infinity half cut would be easiest.... but i'm open to suggestions

I had done a lot of research on the 6.2 and 6.5 before that.
Early 6.2's develop cracks in the webs at the main bearings. The castings were changed to fix this when the 6.5 was introduced (late 6.2 used this same casting). I used to know the casting number when they changed, but I have not retained that info.
6.2 and 6.5 suffer from cracks in the heads, but this is easy to repair by reaming the affected water passage and fitting a sleeve.
They have cooling problems in the rear of the cylinder heads, where pockets of steam occur, which affects heat transfer to the water. This is not related to overall water temperature as registered by the temp gauge. This was cured in late 6.5's by fitting dual thermostats and a high output water pump that can flush the pockests of steam out of the heads.
You can not easily retrofit the high output water pump to earlier engines as it rotates in the opposite direction and is driven by a serpentine belt.
You have to keep a good watch on the rubber in the harmonic balancer. When it deteriorates (starts to bulge) they are prone to breaking the crankshaft.
If the bolt that retains the harmonic balancer is not tightened correctly, they will flog out the keyway in the crankshaft.
You should also fit a good oil cooler for these engines.

The block casting was modified, with thicker webs, when the 6.5L was introduced. Later 6.2L use the same casting (just a smaller bore).
Most head cracking can be repaired by fitting a sleeve in the water passage that the crack is in.
Later 6.5L have a high output water pump to cure this. The problem is hot spots in the head forming pockets of steam. The pockets of steam prevent water contact with the metal and thus poor heat conduction. The HO (high output) pump is able to flush the pockets of steam out of the heads.
Retro fitting the HO pump to earlier models in not practical. The HO pump is driven in the reverse rotation by a serpentine belt.
You have probably also heard of the problem with broken crankshafts. It is generaly believed that this is due to harmonic balancers with deteriorated rubber element. If there is any sign of the rubber bulging out, the balancer should be replaced. Also, if the bolt retaining the balancer is not torqued correctly the keyway in the crank flogs out.
Get an Isuzu engine from a truck instead. Either 4 or 6 cyl Isuzu (both are better than chevy diesel) and these trucks are everywhere here. BTW Isuzu designed the 6.6L duramax engine that replaced the 6.5L in chevy trucks.
I dunno if this is smashed enough to go cheap but there's a very nice, very torquey motor in it. Almost 500 Nm of torque and a lot of it down low in the rev range, arguably a better option for a 4WD than either the Vh45 or even the 5.7 litre holden motor, both of which have less grunt down low where it matters.
If I weren't saving a house deposit so intensely I'd probably be going along to the auction. I think these are a great motor to consider, but I'm not at all sure what kind of prices they're going for.
hey i have a commadore vn ss 185kw motor and all bits needed plus a complete conversion kit to fit a gq 4.2efi you may need to get an efi fuel pump and a commadore ac pump if you want ac working $5000 ono

honestly id probly look into a Chev diesel 6.5L plently of power with an addaptor to bolt the 4.2L gear box on , will have to move the engine mounts decent radiator, oil cooler, feul pump
i bben thinking about this myself
the old man runs the 6.5L and has not yet any problems to date it has been rebuilt as the other 6.2L went boom or somthing
Anybody know if the Infiniti was an East/West motor? there is a couple listed on ebay.... one looks like an east/west, the other i'm not sure.
The inlet manifold looks like it's E/W...... but i think i can see a rocker cover there facing the right direction....... would be interesting if it's right.... good price.

I'm biased of course, but the Chev diesel is just SOOOOO SIMPLE. My ex-military 6.2 has a wire to open the injector pump solenoid, and wires to the relay I fitted to manually operate the glow plugs. Nothing much to go wrong there. I've had it running COMPLETELY SUBMERGED in the Victoria River (not that I recommend it.). I get 19mpg everywhere, towing, unladen....everywhere. I actually think it's a bit better than this as the speedo is reading about 10% slow.
It's pointless to compare engines by looking at a spec sheet. You need to drive something with a similar engine fitted.
I fitted my engine almost single-handedly and kept every receipt, even for paints, nuts/bolts/washers. $6700.00 5 years ago. Mind you, knowing what I know now, it could easily have blown out to a lot more.

i looked at the GM Diesel......... they are easier to fit, but they are pricey as well. a 6.5 T/D would be nice... a bit more grunt......

I have just finished puting the q45 in my Patrol . It already had one when I purchased the car , but it was shot and the conversion wasnt the best. I have taken heaps of photos and might even have some spare engine bits if you get into trouble .
If your in Melbourne , your welcome to come past and have a look at what work needs to be done .

Surely some work to a 4.2 or even a 4.5 nissan 6 would produce more useable torque than a 4.5 V8 ? Complex looking engine, i wouldnt want to drown that or break down anywhere even slightly remote.
Saddle up tonto, its the not so loanrangie! . 98 TDI DISCO lightly modded with more to come.

reading what was posted in the Nissan section, i'm beggining to lean more towards the Holden V8..... easy to get parts for, and a lot more people have done it...... easier to get tech help for it.

V8 huh mate we do the dloows kit as it does everything for the coversion, when you are a little closer to deciding what engine I can price it all up for you for a reference
If the above post did not offend you in any way please PM me so I can try harder!!
I wouldnt look at the power fiqure's between a petrol and diesel v8 the diesel is alot better to drive than any petrol the torque is what you want for 4wdriving roe and believe me there amazing.

I'll get in touchy by phone Adam...... i'm just trying to source an engine. I'm going to allow probably 5 grand to do the lot... surely i could buy the whole lot for that, including incidentals like zorst, hoses, shit like that.
I will be ordering some castor plates probably tonight

$5000!! A general rule of thumb for engine
swaps is to work out a budget then double it.
$2000 for holden 304
$800ish adaptor kit
$600 clutch
$1300 zorst/extractors
$500 wiring interface
It adds up pretty quick. If you do alot yourself you will save yourself a few bob. But honestly I think the amount you stated to do the whole lot may not be achievable. Not saying it cant be done, but most conversions cost between 10@15 G

I priced a zorst already...... if i provide a cat, which i can get cheap 2 into 1 sports system (standard cast iron headers, 2 1/2" pipe) $350
i am banking on 2 grand for an engine, 1 grand for an adaptor kit, 300 bux for the engine mount kit, it's auto, so no clutch needed, add wiring interface, a little over 4 grand....... allowing for the "X" factor..... will end up over 5 i know...... but i have to convince the good wife (and myself ) that it can be done on a budget...... and we all know how good a budget is

Too true, that..........
I started off by thinking about solutions to a IFS diff that kept shitting itself.
Well, if you go SAS then you have to match the rear end with the front.... need to rejig all the suspension then.....but they weigh considerably more and need more power to drive them....so we have to put in a more powerful engine to drive it....which needs a transmission to match....and a tcase (why not get some decent gearing for them while you're there)....might as well stick the diffs on some decent tyres.....
Be very glad when it's done, but what a money pit

it's only money after all and besides... at my age, i blame mid-life crisis, which i might add is a lot of fun!! I am the only 44 year old teenager you'll ever meet
