Just a quick ask I was wondering how roughly how much extra power my car will make once I swap then engine out of a different EF falcon with a bit of work to the engine such as - engine work- 2500 stall converter, pace maker extractors, lukey cat back 2.5in exhaust system, pod, double valve springs, roller rockers,stage 2 cam, head rated at 600hp, anyone have any idea about this before I throw my money at him. keep in mind I am getting fairly cheap is it worth it

EF I6 already has roller rockers.

What "Stage 2" Cam is it. Every supplier has a different spec for their "Stages"?

What head work will be done?

What engine work?

How many Km on the "New" engine?

Stall convertor will have no effect on increasing RwKw.

Extractors and 2.5" exhaust is good. Pod is a waste of time.

How cheap is cheap?

I don't much about the car apart from what has been listed I went and had a breif look at it and it starts fine sounds good no problems that I could pick from what I heard a few minor leaks tappet cover and such but its only costing me 600 for the whole car this comes with front - camber maxed out, larger sway bar, pedders super low gas rider suspension, dba brake discs cross drilled and slotted, these extra aswell it was set up to be a track car as far as I know when I checked the KMs it had about 240 I asked and he said the engine iteself has about 100

$600 is cheap enough, but you need more info on what is done to the motor.

If he has built it up as atrack car then he will know what is in it and what has been done.
