I am thinking about concentrating on getting the most out of the Buick V6 engines internal's while staying true to Natural Aspiration.
I don't know much what can actually be done internally to the engine.
Roller rockers Cam High compression pistons .. what else?
Even though I've mentioned the above 3, roughly how much do they cost and what is their effect on the engine in power gains?

For doing the engine right it's recommended to do: Porting the head Double Timing chain Balancing the crank and rods Then an average worked motor would cost $2000plus(aproximate)in parts alone. |

A mate got a price to make around 140kw @ the rears for around $4600-5000. This was if you pull the engine your self. Don't know how it's manners would be (lumpy cam) but to give you an idea.

| Has anyone had a chop of the Crow stage 3 cam? It apparently does not require headwork. Just looking at doing it in the VN as I only want a mild street cam nothing too lumpy. |

Why not look for Wade Cam?. No matter what when you are pulling out the head its a good idea do some head work. You can do that but you would loose in some effectiveness due to the stock head. Cheers |

| As from my experience it costs 800 bucks to do the heads and sicne it's only my missus car I dont want to spend too much on it when I still have to finish my VS off. I will have a look at the Wade cams though as I have heard good reports about them. |

To get 140kws a the wheel its realy easy . Get the heads worked by a reputable head specialist, Make sure he has a flowbench. In melb I recomend Flowcraft ,Around $800 . Pick a good cam, I recomend Wade 1114a , or 992a if you want a smooth idle still. Get the heads and manifold shaved 30thou to get higher comp . If your motor is old and needs a rebuild you can get away with a standard bottom end rebuid , Or an ACL Race series Kit to get 9:5 comp or 10:5 with the shaved heads too . Single Row Crow Chain( Don't got double ) ,Crow Valve springs, ,retainers and locks . No need for Roller Rockers so save your money .
This will need premuim fuel though .
Also a good set of extractors and a cat back exhaust too if you haven't already got it.

this is what i have in my vn v6.
stage 3 crow cam shaved heads 50thou cylinders bored out 30thou roller rockers heavily ported & polished heads larger throttle body POD filter. dont know whether to go POD or cold air intake. solid lifters crow springs ACL flat top pistons chemically dipped and polished crackshaft 2.5" exhaust system, extractors & hi flow cats. and 3.55 diff with LSD.
TVS, the stage 3 cam is good. they reckon on the crow website u dont even need aftermarket pistons. its off its tits with all the other stuff done aswell. putting it on the dyno soon so ill let u know how much it gets with these mods.

So, if u do all this work done to a stock engine to make it have more power than stock, do u think it will run using the same computer or will u have to change the computer chip in ecu? i know changing the computer will help it, but it is possible to have a worked motor using a standard chip or will it read different things and not run properly?? thanks

Best bet is to get it custom tuned. I haven't tuned the missus VN yet and I have jsut put pod, extractors, at and exhaust on it and it feels a lot better, but could do with a tune.
TOPGEAR - yeah I was just going to throw the stage 3 in and see how it goes. 120rwkw or so isnt going to worry stock pistons. My VS ran around with 210rwkw for yonks before I rebuilt it, and I only rebuilt it because it blew a stock head gasket. |

I have been screwing around with my vn V6 for a few years now, all i have done to the car is as follows; extractors 3" system no cat, i fitted an old apexi fuel ratio adjuster (adjusts map sensor output) to rich up the fuel mix and fabricated a custom twin throttle body manifold which cost me all of $250 to fabricate ($75 for parts from wreckers and $175 for polishing the manifold) to date this car has 131 kw @RW and the engine has done 300,000 kms. I would like to know more about engine internal components such as cams, cranks, and the like as there is very little info out there about the buick 231, What are Haltech ems's like ? good or not worth the money ? Any info would be greatly appreciated p.s. i may be interested in making more of these manifolds if there is sufficient interest, i have all dyno results before and after to back up my claims. |

| If you can build a TTB manifold that cheap I'd prolly be interested. |

dude been there done that and redoing it all over again. had a vp v6 worked off its nuts pushing 180kw in the rear wheels thats none turboed or supercharged just worked.but i blow it up cozi thought it wise to add direct port nos without redoign the heads and blow the bottom end out the arse. anyway i will be rebuilding another vp motor soon so ill do a right up for you guys if you want.pics info etc. |
