does anyone know anything about chev V8s?

thinking about either turboing my safari or putting V8 in

was thinking either a 350 or 383

will the gearbox handle the v8 punishment?

anything else some of you could let some light on please would be much appreciated

put a 400 in it, my dad has a injected 383 and the running gear is sweet as, his one has a larger heavy duty chev clutch to fix that problem as well, but i agree with the weight, those boxes and transfer cases are heavy as

http://www.patrol4x4.com/forum/ has a fair bit on the diesel chev v8 conversions.

just be carefull with later model GU's tho, seams to be a few problems with chassis cracking.

A friend of mine in Nelson has fitted a Chev V8 to his short wheelbase. He has also fitted the chev auto gearbox as well. He said it is a lot lighter than the nissan gear.
I cant give you more details but if you need to know specific specs. PM me and I will find out as he only works about a kilometer from my house

dad put an lt1 and chev auto into his nissan in about 2001 I think. It did about till 06 as a daily drive (on 35's) and 07 as a tow vehicle and offroader until the auto clutch packs gave out. Currently awaiting an ls1 and new auto, but gonna change the diff ratios this time (too high on 3.9's). It went really well (LWB) for a heavy nissan. The new engine and gearbox is 40% lighter than th eoriginal

aah are we talking about diesels? no its a petty, i wouldnt go near those smelly old things

but seriously, have heard the 350 diesel is a very pus engine and the 6.3l is the best one, but may be best to do a bit of reading on that

nope http://en.wikipedia.org/wiki/GM_LT_engine

yeah thats what i had heard
im quite keen on keeping my truck diesel but love sound of a V8

get a 6.5 chev diesel ,6.2 were ratly old things and made bugger all power .i know 2 guys who put 6.2 diesels in and resulted in one being taken out and replaced with a petrol and the other sits in a workshop as an occasional bed !!!!

ok more questions

where would i find a 6.5L?
how much are they worth?

Heath Lawson in AU is now running a 6.6L Duramax with Alison 1000 trans (twin pto outputs!!) in his GU ute. 440HP at the wheels in stock form. Running it on 1/4 mile instead of Outback Challenges now, hopes for 11 sec pass once its dialed in. Pretty respectable for a 2.5T truck.

The chev diesels don't seem to be anything to write home about. You'd be better with a TD42 and a turbo.
Here's some light reading.

The duramax however.

Theres a 6.2L turbo'd and intercooled on tardeme.

you are better off getting a good turbo kit for the TD42 which well make a huge difference to how it performs.
The TD42 is a very heavy engine and replacing it with a even heaver one doesn't make scents IMO that only has alittle bit more power.

My 1997 Shorty GQ was a factory turbo model and I fitted a propane kit ex USA. However, since I have had the 5.7 litre chev V8 installed (3 years), it goes far better. Still running the GQ gearbox etc with 4.625 diffs and reduction crawlers in the low ratio box to hold it back on steep down hills.

Now theres a great truck all setup ready to rock and roll for you injected V8 complete with Tunercat and Datamaster tuning programs on a laptop to let you twinkle with the tuning.

Turoa and cool bananas will vouch for it

hi, where do you source propane injection from, i have an 80 series with the 24v motor, i want some more grunt for towing, whats the best solution? propane, bigger turbo, intercooler? dont want to change engine

This is where I purchased my kit from

www.dieselperformanceproducts.com

Another chap Colin Brewer, who use to live in Wellywood also had one on his Nissan GQ, but now he is in Aussie.

thanks

Before you spend any money on propane, read this:

Intercooler if you don't already have one, then more boost and fuel. Buy yourself both boost and EGT gauges before doing either.

so the first thing would be to buy a good quality intercooler kit, then boost turbo, sshould the exhaust be done first or later, has 2.1/4 inch as standard, cut the big muffler out today and replaced that with straight pipe

Did the muffler make any difference?

I've got 2 1/4 on my diesel at the moment. I plan to go bigger but I have a lot of projects competing for my time and money.

It makes sense to do the exhaust when you know you're sticking with that turbo. Otherwise you need to remake the dump pipe twice.

Another point with fitting a propane kit is that if your truck is a trayback, the job is a lot simpler. Mine was not and hence the propane, which was in a barbeque bottle inside the rear of the truck, had to be in a sealed container with a hole down through the floor. I fitted a ply box all glued and screwed together, cut a hole in the bottom and out through the floor of the Nissan. The hole acted as two items, - one for letting the cables coming to the bottle come in and two it let any escaped propane out of the cab, if it leaked. My system was inspected and passed WOF checks. It now been sold and the chap still hasnt fitted it to his Nissan.

When you want extra power, you just flicked on the dash switch and watched propelled into the air!!!!

On a tray back, its alot easier to install cause the barbeque bottle is not inside your cab

cheers for all you info there guys

have decided to keep the td42 and add a turbo from a tractor that i can "get" reasonably cheap from the tractor company we share a building with

will keep you all posted

also where can i find an exhust manifold for turbo? or should i give it a shot and make 1?

exhaust is almost always the first engine mod that should be done.

it surprised me how much difference it made, no diff from a standing stsrt but when rolling it made a noticeable change, gonna do an intercooler next week. i see 1 advertised on a site in nz for my car, will give that a go i think and then do a 3 inch exhaust

Try this http://www.4wdbits.co.nz/ProductDetails ... uctID=1208

I've been for a trip in the 80 series this is fitted to and it made a noticable difference to power and droped the EGT by between 50 and 100 degrees.
it is now a full water to air and is even better.

going to get hold of them over the next couple of days, should i wait till the full water to air intercooler comes out, or would i be happy with the air to air one?

they have a working prototype of the water to air now so shouldn't be far from production.
in terms of efficiency it would be strait air to air then air to air with a hole in the bonnet and a scoop then water to air. it all depends how far you want to go. And how much you want to spend
