Engine Conversion For Gq Patrol  

lil_bobby_260

Im doing a ford 5.0L conversion in my GQ.
Are you going to be running fuel injection? If so - is your GQ EFI already, or carbie?
.
To keep things simple i am just getting a mid 90s EFI 302 Windsor, just before they went to coilpack ignition from distributor, and deleting all the EFI gear (sensors, injectors etc etc), fitting an early style edelbrock manifold, and just running straight gas. No petrol system whatsoever. Running a gas cam aimed at a good torque curve instead of top end power, and a snorkel fed air intake with extractors etc etc. Expecting goooood power, good economy, and a pretty easy installation.
There are adapters kicking about that you can buy, and probably engine mounts too, but im making my own.

This is pretty much the only site you need. He has everything to do conversions.
Jump on patrol4x4.com, outerlimits and 4wdaction forum's for more info etc.

rb30et, bolt straight in no fuckin around, mates one made 115kw with 35's

RIPGTR

i wouldnt bother with the 5L just go straight to the LS engine like i did. sooo much more stronger. if ya wanna have a look at mine just shout out and ill send ya some pics

no more holdens

A stock TB42 patrol will lunch a RB30 Turbo patrol
All day , every day

Youre talking a 3 tonne , or close enuf 4x4 , not a VL commodore

Doin any V8 conversion in a patrol , unless your gunna doin all the work yourself
8-10 K area

5L , I wouldnt bother a tuff turbo diesel will give ya a run
LS1 minimum

As mentioned above , patrol 4x4.com or any other dedicated 4x4 forum will help you

Depends on what he is doing the conversion for.
For instance, im not building mine to be a race car or hill climb comp truck, i just want a replacement motor that is cheap and easy on parts, reliable, and has enough torque to get the job done. Im not building it to be better than turbo diesels or RB30ET's (which are a stupid thing to put in a patrol anyway), just for a solid motor that is efficient and reliable and enough power for the vehicle.

no more holdens

Yep your right there
But try telling all the wannabees


re the conversion , as i mention itll cost whatever it has to
Depending on as you know, contacts, parts prices and getting on the spanners
Its a very common topic over at patrol4x4.com
A bitta reading will reveal , alot think that its a cheap conversion,and are shocked at what some do end up costing

lol at all u fuckers hating on the rb30et conversion, my mates one is sick and is just as fast as any v6 commodore out there, and wen his engine breaks we just buy a $300 VL, swap the engines over then scrap the VL for $300. take me a weekend of drinking beers and eating pizza to do it,he did his entire conversion for less then 2g, thats including exhaust and fuel system. good luck gettin any v8 for that much

I'd burn that in my mothers old 4 cylinder mazda 323.

no more holdens

RB30 turbos , keep em in dunnyboxes
Patrols are too heavy for them

Unless ol mate is running some serious boost , intercooler
A 4.2 pettie , will disgrace him

Do a search ,Patrol4x4.com
Youll be surprised how much people do HATE on them
How much power even the turbo RB30 doesnt have

lil_bobby_260

Mate youre an idiot. "my mates one is sick" is the first clue, and "it beats any v6 commodore out there" was the second one.
Youll find that in the 4WD section we use our cars to GO OFFROAD. Not race v6 commodores like some dickhead flat-capper, champ.
Theyre a stupid engine for a 4WD because youve gotta rev the fuck out of them to make power. Not that handy when you are cruising up 45 degree inclines, or trying to pull someone out of something.
Way to make yourself sound like.... a douche.

Duramax 6.6 litre V8 diesel with 5 speed allison auto /thread.

speaking of TB engines..
my (GU?) has the 4.5L petrol donk in it.. wondering if anyone has a ballpark figure for how much the motor weighs


shiit, look out

88200sx

my uncle has a 25det in a gu wagon, makes 330hpatw it farking hoots on the street runing 33". it is awesome offroad, be suprised how torquey it is even off boost better then the 3l deisel was.

take a trip out cruiser park sometime when there are events on, every secound patrol has a rb30 in it, very few people have turbo diesel competing. there are a few v8 trolls out there they do not keep up with the rb30t, weather it be up a hill, around a track or a crosscountry race challenge.

255Kg + flywheel + gearbox

clutch-monkey

thanks! couldn't find it anywhere
hows that compare to an RB?

iamhappy46

Surprisingly, the difference is minimal maybe 10Kg difference. Mainly due to the extra hollow sections in the block for water galleries etc and the rotating mass having negible difference.


Similiar thing with the Nissan VQ35... no one would suspect that a 3.5L V6 weighs less than an SR20DET

lil_bobby_260

I think you will find that is because they are an easy, cheap way to make high end hp. Not because they are better than a big turbo diesel. You grenade an rb30et, you just pull one from a vl or whatever and throw you bolt ons back on. Turbo diesel isn't quite as cheap. Good competition engine. But don't compare to a v8 or turbo diesel for torque no matter what anyone tells you. They're only good at high revs and wide open throttle, and like I said- cheap.

clutch-monkey

i've seen a few of them on the 4x4 forums turbo'd, was wondering about sticking one in a R32 GTST or similar, for laughs. would need a different sump though..

no more holdens

Turbo diesels have lots of TORQUE
They dont need to rev to 7-8,000 RPM to get their power
RB30 t , have to rev

The ONLY advantage goin an RB30 Vs a 4.2 turbo diesel,is as mentioned the cost
To rebuild a diesel injection pump alone , should buy a yard full of 2nd hand Vl dunnydores

330 HP at the wheels
Got a dyno print out ???

Hur dur hur hur. Derp derp walapp herp derp hur dur.

I raced v6 commo's when I had my Cruiser - scared the shit outta them when I could keep up
1FZ > RB30.
