Converting V6 to V8

[Trennaa]

I just want to know the costs, for replacing the VN Buick V6 to the equivilent V8. Brakes don't need to be looked at, but what about Transmission/tailshaft/diff? And does anyone know an estimation to the closest hundred? anyone done this before?

im not to sure bout most of the other stuff... i think the diff centers are the same from v6 to v8 just maybe a different ratio but im not certain, getiing the engine wired up will be pretty expensive, im getting my rb30 2 efi5ltr wired up for 500 from a friend of the family so that is really good ive been told its usually about the 1g mark

1. buy a crashed 5ltr - $2500 max
2. transfer all gear from 5ltr into your car - FREE (unless you have to pay for labour..... then about $1500-$2000+)
3. go do some donuts.

it would be a direct bolt out/bolt in conversion

and you can make some money back by selling your v6 and wrecking the rest of the parts on the stacked car.....

yeah. buy a vq or a calais. then there are lots of parts to sell.

 

[Trennaa]

it ain't for me.
anyone know what a V8 engine is worth?

How long is a piece of string?

Do you want an engine that needs a rebuild, want one that has had work done?

Stock and possibly in good nick around $2500-3000 for engine and ecu.

 

[Trennaa]

Not a rebuilt, one thats running or so.. Work done would be a bonus, but not required.

if u had bilstein suspension would u still need to change the front suspension to accomodate for a v8?

 

[Lumps of cheese]

Well i sold my 5 ltr. with auto, 185kw(out of a vs ss) 112000 klms. for $4200
Only thing it didn't come with was the radiator.
I was putting in my wb but kids put a stop to that!
I think that price was pretty good, should get them cheaper i would think tho'.

obviously the comp and brakes need changing,
but what about the wiring loom?
what about the engine mounts aswell, do you just remove the v6 mounts
and replace it with v8 mounts?

2 more things im unsure if they would need changing?
the dash cluster? the tacho and speedo might be wrong

and the front springs? maybe v6 front springs
are not strong enough?

can anyone confirm if any of this needs changing thanks.
