GQ TURBO PROJECT

[FAT GQ]

INSTALLING RB30 TURBO INTO A GQ PATROL, ANY WORDS OF ADVISE OR ASSISTANCE WOULD BE GREATLY APPRECIATED FELLAS! I HAVE NEVER DONE AN ENGINE CONVERSION IN MY LIFE. HAVE GOT MOTOR AND LOOM SO FAR COMPUTER IS ORGANISED ANY HEADS UP ON ANYTHING FOR THIS BUILD.
CHEERS JAKE.

[GRINCH]

spend the dollars on a decent clutch while the motors out,

[marty braj]

are you using the rb30 from a gq? or a vl..is it a conversion and is it carby or efi..dont no much about the gq rb30 but if ur converting a vl rb30 use a s2 block because they have the turbo lines on the block...
go 2 calaisturbo.com.au and have a sniff around..alot of info on rb30's

[GQturbo]

Id go straight gas with gas research, that way u dont have to worry about putting in a computer and loom out of a vl which is like over 20 years old. too easy to run into problems. just finished turbo'ing my GQ which has carby rb30, used vl inlet manifold, but ran straight gas with a gas research carby, nutter did same conversion first and has excellent info and pics on this site. deff worth doing it tho goes hard !!!

He did say he had a vl turbo motor, so as far as were aware, it is a SII Block. But be carefulle of the std vl motor thats been turboed, as they do ping there arse off when you start to run higher boost (above 7psi) you can advance the timing to compensate, but its not ideal)

Running gas research is a good and easy option, allowing you to keep the current motor, but means you have to stick a large gas tank somewhere in the car.

Id go efi everyday, but i'd take a seriouse look at using the skyline loom as it is separate from the rest of the loom - its an easier install.
other wise, your going to have to either cut the vl loom and or, just find the right wires and chuck the whole loom in the car onto top of the current patrol loom.

Clutch is the only thing i'd be looking out for (put a new one in), and stick the computer somewhere high in the dash, so it stays dry. Adz dad has done the gas set up, and so has nutterqu

hey mate if your going to do a low mount manifold you have to notch out your engine mount but only one side. i'v go the gu 2.8 turbo diesel heavy duty clutch in mine and its great strong as. you'll need to get a throttle cable that will reach, a bigger fuel pump will be good i have a xr6 turbo internal pump a fuel regulator. if you have the standard vl gear you'll need the turbo injectors a turbo air sensor, you can use the normal vl distributor with a good crank angle sensor, it would be a goo idea to run a intercooler if you are not going to decompress it. or you can do the gas thing. if you want some more info pm me and i'll send some pics of my set up cheers

[GRINCH]

im running mine intercooled on straight gas with gas research and a wolf ecu and gen 3 coil packs for the ignition, goes heaps better then standard. i was running vl ecu etc and had lots of dramas due to age of parts, so got the shits and went to a wolf with a new loom and had no dramas since. mine will be going gen3 v8 in the near futre the turbo just doesnt do it for me, you cant beat the sound of a v8

[NutterGQ]

Re-consider the EFI, get gas research installed with a 100 litre fill able tank fully installed and complianced your only out of pocket $1000.00 with the gas grant, this means no MAF, no old loom, no CAS which there known to eat no need for 3TM computer nothing, and you will be EPA compliant providing you dont use a vent to atmo BOV..(if you do smack head into computer monitor as your read this and say "I should have bought a poofy ricer").....and of course $45.00 for a full tank of gas. If you do go the VL ECU you really need to chip and tune to make it run with any extra boost and the intercooler budget another $600-$800 for this.

On top of this if you intercool it you can run a fair whack of boost. If the motor is out of the car change the head gasket now! dont use repco shit, either use and Cometic MLS or Japanese Carbon Composite unit, anything else will end in a tear down.

If it is a VL turbo motor (A8 Block etc) the static compression is a bit low by today's standards and fuel and really in a patrol not ideal, so expect to use a bit of boost to help it along. Wont help you off boost though will be lazy, also if it has the factory T3 turbo don't get excited you cant push much out of them.

The low mount manifold can be used but for around $400.00 you can buy a high mount ACE or for $1200.00 a 6 Boost Steam pipe job, DO NOT buy an ebay manifold, they use a merge collector instead of lazer cut merge section and will crack.....again and again and again, the ACE is not prone to this the 6 boost is said never to have cracked.

High mounting is nice, great for clearance, great for cooler pipes, keeps it out of the water and no mods required for engine mounts, also more power to be made faster spool up etc.

Theres more but it will start you off.


hang on more basic info, Patrol sump and VL way different too, also if it is a factory turbo motor sell the intake manifold to some mario then put the N/A manifold on, it has better runner length and can be bought for $10.00.

[phat gq]

the motor is an A8 original turbo motor.
do i have to change or modify the sump or just use the one on it.
should a surge tank be used or is there another option for the fuel stuff.

Gqs have turbo lines on the block too

im happy to throw/pm/mail pics up of our install, pretty much the same as nutters....

Well if you go petrol you may or may not need the surge tank depending on how far you go, also are you just feeding it out of the stock rear mounted tank or from a long ranger?

you need to buy a patrol sump and pick up, the VL one is smaller and in wrong spot, its a shame you went the VL way as its not as suitable as a High Comp Low Boost setup in your car, but if your gonna persist there's some food for thought.

Surge tank is really easy to set up. Consider using a lift pump before the tank - feeding into the surge, a high flow vl pump heading to the injector rail, and a return line to the surge tank- it will never run dry and will have fuel all the time.

Even with the a8, its it going to have the same, and or similar torque figures as the std carbi motor? Only gains are up the rev range, like a wet rutted hill climb when you need some arse kicking power..

You dont always want the turbo to spool quickly, because sometimes, you need to crawl off boost.

either way, your going to get the performace you want. Gas works at all angles, like efi, gas is simple and very effective and works really well. My only issue with gas is the tank, i hate it. thats why i bought an efi 4.2 turbo patrol over a gas one.

My suggestion is if you have never driven a Hi Comp RB30 with the same mods as a Low Comp you don't compare lol...I say this assuming i'm right as those of us who have know exactly what going from 7.5 static to 9.2 static at the same boost does, boost spools earlier and is delivered much harder....in the wet mine will spin 3rd and 4th when it comes on boost.....

As for crawling you only get boost when you got load and enough rpm to make it boost, neither of which you'll get if really crawling, shame your not in Melb I would happily take you out to squash internet myths.

[phat gq]

so can i use my rb30 carbi sump for the A8 motor.
any good head gaskets i should use. what do you guys rekon about the highmount turbo manifolds of ebay ??? i think there called monster manifolds

ahhh ok...try reading what's already been written

[NutterGQ]

Just realised his user name is new and has changed too....somebody fruckin around.

[phat gq]

HEY BUDY NO YOUR WRONG THIS WAS MY GIRLFRIENDS EMAIL IT HAS BEEN CANCELLED AND HAD TO CREATE A NEW USER NAME.
FUTURE REFERENCE DONT POST IF YOU DONT HAVE ANYTHING USEFULL TO SAY.
ANY INFO ON THIS CONVERSION WILL BE GREATLY APPRECIATED FELLAS

[mkpatrol]

[cooki_monsta]

2nd the popcorn and jeesus mate nutter was just trying to help, no need to get sand in your vagina over it

anyhow if your new to boost go a low comp engine, high comp can be scary at times

as has been said before ebay manifolds are cheap shit and wont last, so buy one at your own will, infact ask if they do bulk orders cos ur gonna need a few of them or get one good one, up to you.

either way a turbo patrol is awsome fun, im still collecting parts to turbo my 4.2 petrol

[tna racing]

75000 kms and no cracks or not warped..........

yeah but no matter what cheap shit you use, you always claim its fine...I think theres more to it but won't bother getting into it, I didn't just say they crack but also why and what their fault is.

as for our thread starter who asked a question, got the answers in detail (look above) changes his name re-joins comes back to the same thread asks the exact same thing I answred in detail and has a go at me, how bout I suggest this...if you are too lazy to read the info I have provided to you don't be a wanker and have a shot. Not only have I done this conversion multiple times but it has ben copied by members here and else where, if you know fruck all about it and need help, comin on here and being a big shot takes away help from those who know and leaves with the kids and those who think they know....I won't be pipin in again and am annoyed only that I can't delete my info and leave you with the other opinions.

[GRINCH]

stay away from the gktech manifolds they are shiit ive welded mine up about 6 times now

[mat_p]

what is a rough cost for doing the turbo?? with straight gas, but dont include the rebate in the final figure.
i was going to go for a ls2 conversion but in the mean time i may consider going the turbo on my rb30 patrol (will buy a seperate block to do the work on and then just dump it in, so as to keep the car on the road as much as possible as its my daily driver).
i had been thinking about just running it all on LPG but if i go straight gas i dont need a computer, right?? i dont know alot about turbo systems so im just guessing after trying to get the jist of it all in here.

[PGS 4WD]

Pretty broad question, how good do you want it. A tough motor could cost over $20k (serious power), a stock second hand N/A motor $500. Turbos cost from $500 to $3000 with an external gate depending on the type and quality. Intercooler can cost from $150 to $2k, piping can be mild steel, alloy or stainless. Sometimes its easier to work out a buget and then see what you can afford.

[phat gq]

ACE high mount manifolds. how much better are they than an ebay manifold. only $100 price diff

[cooki_monsta]

hey mat p, straight gas is definatly the way to go, you wont need a computer as you run a gas carbie style mixer in blow through, as prev stated.

im trying to do this myself, and so far i have allowed 5g just to stock pile all the parts i need:

Turbo
Manifold
Intercooler
Gas system (im using impco 425 because its free, but g/r is apparently better)
Ignition (Petronix, and some sort of spark enhancer)
Boost control if internal wastegate or allow 300 or so for an external gate
Oil lines
Exhaust

then you need tuning, fitting etc

at the end of the day its gonna be good fun when its finished, oh and when its ready drop down to see joel so he can remap your dissy
