got a port and polish

[Big E]

got a port and polish on my vt v6 the other day. with other mods its making 150.3 rwkw. feels awesome. just wondering how powerful some other n/a ecotec sixes are. and what mods have been done to achieve the output.

[TI3VOM]

What have you also got done?? tell me yours and I'll tell you mine

[Big E]

69mm throttle body, 12mm plenum spacer, pacemaker extractors, 2.5" custom bent single high flow cat back exhaust, otr cold air intake, full msd ignition, custom high ratio roller rockers, 105 pound valve springs, intake manifold and heads ported and polished. cant think of much more under the bonnet.

I achieved 145rwkw with a baby cam, raised compression, port and polish, CAI, extractors and exhaust, and tune of course. But I think my single ordinary cat exhaust is restrictive, also the lifters and pushrods with badly setup when it was being tuned and measured, as the engine stopped making power at 5400rpm when it should have gone up to the mid 6k in revs. I have since fixed the lifter problem but haven't got it re-dynoed.

I can't see why your car would make 150rwkw with only that.

[Big E]

yer im in the process of a cam at the moment, still umming and uhhing you know. yer the standard computer can only be retuned so much, so cam and a computer are next on my list.

[acarmody]

Actually the stock ECU can be tuned A LOT, just got to find a decent tuner. Don't buy an aftermarket ECU, it will be a huge waste of money and still won't be as good as the factory computer.

all sounds good cept for the msd ignition, woulda been a good waste of money as there stuff isnt cheap

[Big E]

yer a wanted the aftermarket ecu to fully retune rather than use a chip when i get a supercharger kit. as for the msd price. i got it really cheap because i did pay a lot for it to begin with but 1 of the coil towers had a fault and they replaced all my ignition and gave me a full refund.

[TI3VOM]

I've got:

* NGK Iridium spark plugs.
* Bosch motor sport racing leads.
* Aunger CAI.
* K&N panel filter.
* Ported throttle body.
* 9mm Throttle body spacer.
* Port matched plenum chamber to T/B and Intake Manifold.
* 7mm plenum spacer + 7mm more to come.
* 12mm manifold spacer.
* 1.9/1.95 ratio Roller Rockers 1.9 on intake and 1.95 on exhaust, soon to be reversed!
* Pacemaker extractors tuned length design.
* Soon to get twin 200CPI cats and custom Y piece.
* 2.5" redback exhaust with rear resi removed.
* Greenfoam tuned.

Will be re-tuned after, swapping RR's around, getting cats installed, maybe putting on MSD ignition coils, and possibly getting the heads reconditioned also with a three angle valve grind, cleaning the bowls + larger valves.

Haven't got it dyno'd yet but would like something in the end of around 180-190RWHP N/A, but would then like to take it to the strip

Tuning the chip in a VT is not the only way to tune the computer, you can get a Kalmaker dyno tune, which has more tuning possibilities than most aftermarket ECU's but still uses the original ECU, which is a very sophisticated computer unit.

Trust me here, the factory ECU can have a full retune done. The chip is where all the data is stored, so basically getting it chipped is the same as getting a whole new ECU. Don't waste money by replacing the factory ECU.

I got msd coils on my vs biggest waste of 300 bucks lol did nothing, only looks good

[Jarrodscv6]

If you need to replace your coils use supercharged v6 ones. They have been proven to be as good if not better than msd ones.

When I inquired through my local dealer, they said that something was not compatible between the L67 and L36 coils.

[acarmody]

Really? I was under the impression they were exactly the same.

[TI3VOM]

Really? I was under the impression they were exactly the same.

So was I, they said something about the voltage not being the same or something like that!
The guy then suggested to go stock L36 ones, when I inquired about MSD he said that every test he has ever seen has suggested that it will be a bit better than stock.

[VKCOMMO]

Just out of curiosity, How much did your P&P set you back?

[Big E]

just the port and polish alone. around $800 i think. i had other things done at the same time though so not 100% sure.

[Big E]

my vt is making 201.6 rwhp at the moment. by the sounds of it you will come very close if not more.

[billy bob]

Had mine dynoed. Got 133rwkw

2.5" sureflo exhaust
pacemaker extractors
1.9 YT roller rockers
24mm plenum spacer
69mm throttle body
lukey air filter
type S CAI
mail order tune

Got some ported heads i need to get revalved. Then I want to install them. Should get me up around 150rwkw

Can it be tuned on the go? If your at the track and want to change something, can this be done with the factory ecu?

I suppose if you had the right equipment.

I don't think your going to get 17rwkw from some ported heads. Maybe if you had a cam and raised compression to go with it.

it can but u need thhe kalmaker software and realtime box then it can be realtime all the time .

In the workshop rally car we've got Ported heads, valves, springs, modified intake manifold, Big cam and standard exhaust manifolds. Has a Vipec and makes 242hp at the wheels
