GU Patrol GM 6ltr V8 6 speed Auto conversion

[BearGUST]

Great stuff! The 6 speed auto should be good, short 1st gear for crawling & 6th with the right diff gears will be perfect for highway.

We've got a V8 H3 Hummer here at work which has a clutch fan so there will be parts out there if you decide to go that way.

cheers guys yeah been keeping me busy this one

as for the LS fan hub from a vortec engine that they run on chevy utes and gmc utes and the hummer you told me about
this would be perfect but the pulley system runs to far forward i would need to move all the belt driven accessory's forward and change the intake to the higher truck based version
that i still may do but it might cost to much when i can just run the stock ve ss radiator and fan set up with a new air con condenser for $660
but yeah still not sure on which way i wanna go yet

[Parra]

good stuff mate!

glad its you doing that and not me. Id be up a certain brown and lumpy creek pretty darn quick.

I hope you have a blast in this thing when shes all back together.

i might just run the commodore radiator and fans for now as i can get a new genuine radiator, air con condenser and fans with shrouding for $660
just a bit worried it might not like being loaded up in the soft sand on a 40'c day
only really one way to find out

That is going to be a monster when it's finished. Awesome thread, I will be watching with anticipation!

[julian14588]

yess i cant wait till its done just want to get out bush and drive

after doing some more research and brain picking i think i will get a heavy duty ally patrol rad and make my own shrouding thermo fans set up which then can all be controlled by the engines ecu and a over ride switch on the dash

bit of a update guy .... spent my money for the car on some well needed holidays . but i did manage to get my headers done took about 50 hours of trial and error.
i may just need to fit a a whiteline sway bar on the front to give some more room on the exhaust (any one got a whiteline sway bar they could show me?)

STARTED OFF AS THIS



THEN 50HRS LATER OF CHOPPING AND TESTING AND REINSTALLING THE ENGINE TILL EVERY THING CLEARED

Following this thread with alot of interest mate coz i want to install a 5.7 in my gu. Just a quick question, what type of headers are they and what car are they supposed to fit into?? Coz there are genie extractors that are made for this install and the marks adaptors ones aswell.

[Trifer]

personally, I'd go the original patrol radiator. But, block off the outlets on each one, fill with water through the neck and see which holds the greater amount of water. That's ur best option.

Good luck. Hope all goes well :-)

[julian14588]

they started off there life as genie extractors, the gq conversion set meant for a ls1 5.7 with nissan manual

5.7 conversion would be a lot easier with getting the belt driven stuff shorted out, you can pretty much buy every thing you need for that conversion off ebay and marks, most of my conversion has been custom brackets and having to mod everything
