basic vn v6 mod ideas? - Aussie V8 | Holden - Ford

madmick · 12-06-2005, 10:09 PM

i decided to start this because i didnt want to jack the crs supercharger thread.
i just want to know some small cheap mods for a little more power.
i was thinking a supercharger, but im gonna sell it in a couple of years so no point blowing heaps of money..

cold air intake
3.9 LSD
shift kitted auto.
extractors
2 1/2" exhaust

and then i get stuck for ideas..

also, between the throttle body and the manifold i got told the black plastic thing can be taken out to allow for more air to flow? is that close to the truth?
i dont want to crack the engine open and start operating.
so any ideas for a little more power are welcome

what is the stock power of a vn v6? and how much power could i expect at the wheels with that combination up there ^?
im gonna get my car dynoed within a few weeks.

stage 3 crow cam, 28% overall power increase..........

roller rockers, pistons maybe ?

get the heads shaved, dont think it would cost that much.

how cheap are u calling cheap ? under the $500 mark ? under $1000 ?

vn is 127kw at the flywheel stock, with stage 3 crow cam its would be like 160, 170 at the engine.

this is what im running....... prices are estimates.....

stage 3 crow cam ($800 ??)
crow springs
roller rockers
extractors ($400)
2.5" exhaust system ($300)
heads shaved 50thou, heavily ported & polished heads ($750)
cylinders bored 40thou
stainless steel valves
forged rods ($250 a rod ??)
ACL bearings
ARP stud kit
rebalanced & polished crank
3.55 diff with LSD ($700 reco)
POD filter ($100)
larger throttle body

putting out 213hp at the wheels with straight unleaded.

diff gears you'll have the most fun with..
a mate had these and they made the car pull so much harder

kransky · 13-06-2005, 03:00 AM

if its aseries 2 vn it should have a restrictor where the intake pipe connects to the intake manifold

mark · 13-06-2005, 09:41 AM

whats the budget?

madmick · 13-06-2005, 08:41 PM

i dont really wanna go above $2000... (not including exhaust or extractors.)
just because its still a 6 and i dont want to waste to much money because ill never make the money back.

[TOPGEAR] · 13-06-2005, 08:43 PM

u should get the stage 3 cam and roller rockers for under $2000.

madmick · 13-06-2005, 09:01 PM

ok so thinking..
diff ratio, lsd
shift kit the auto
cold air intake
pod filter (you know, the air filters, is that the name of them?)
and a chip? like this one on ebay
http://cgi.ebay.com.au/ws/eBayISAPI....556259100&rd=1

also remove the plastic thing between the throttle body and manifold..

that should give me a bit of kick yeah?

madmick · 13-06-2005, 09:06 PM

yep.?

HYPWR · 13-06-2005, 09:11 PM

Had all these mods minus the LSD, higher diff ratio , and the CAI instead of a pod filter in my old VN . Alot of improvement for little money!! , from there it just gets all too expensive to really warrent charging / stroking the V6

alloytec V6 would be fun to work with

madmick · 16-06-2005, 06:22 PM

what years were vn series 1 and 2? i need to know what mine is... it was made in june 1990.
"if its aseries 2 vn it should have a restrictor where the intake pipe connects to the intake manifold" (what kransky said up there ^)
i think it has that? how else can i tell?

[TOPGEAR] · 16-06-2005, 07:45 PM

its series 2.

series 2 were 1990 and 1991.

series 1= top radiator hose goes to the back of the engine.
coolant reservoir bottle has a screw on cap

series 2= top radiator hose goes to the front of the engine.
coolant reservoir bottle has a push on cap

madmick · 16-06-2005, 09:06 PM

ok cool.. thanks topgear

kransky · 18-06-2005, 02:33 PM

from what i have heard, after you get rid of the plastic restrictor you have to rev the car at about 3000 rpm for about 8 seconds to let the computer figure out whats going on with the extra air flow
