Good set of heads these i must say, at 50K these have barely been used..oh did i forget to say that these were capable of breathing up to 500BHP in standard formm....

Good luck with sale Mad Hammer

Thanks mate, I have a exact same going on my TypeR build actually, those have done more miles but have been rebuilt. They will be working with a MD321T and I expect near 500bhp with meth on those.

These one for sale were on a standard car also and have never seen high boost ! Shame I got aquired them after I had had my others rebuilt :(

Hmm, did you know valve lift for intake and exhaust cams?
As i have v4 sti heads and would be nice to know if these heads have more aggressive cams.
Really thanks!

I have been told there is no or very little difference between V3 and V4 heads. Therefore not an upgrade for you mate.

Doh, i know that the castings, valves, springs and buckets are the same, but maybe the cams are different... I've searched everywhere for this info but i've not fount it :(
I know that v4 sti cams have the following characteristics (i've measured them...):
In lift : 8.50mm
In dur : 260° (at 0.1mm, plus 0.20mm of play)
Ex lift : 8.60mm
In dur : 246° (at 0.1mm, plus 0.25mm of play)

And that v4 wrx (italian) cams are :
In lift : 8.40mm
In dur : 256° (at 0.1mm, plus 0.20mm of play)
Ex lift : 8.40mm
In dur : 238° (at 0.1mm, plus 0.25mm of play)

From what i've read, the v3 sti has the best cam profile avaible...

I have heard that on more than one occasion, but have empirical data sorry

That 3 and 4 are the same mate ?

No not at all, that the version3 are more aggressive than the version4 cams.
Heard it a few times and even remember the head honcho of sti saying his favourite Impreza was a version 3 sti, because the cams were the best.
Sorry though, I dont have anything concrete to back that up.
****Note, the post above should have said but don't have empirical data sorry***

Free bump for a great set of heads at a great price :thumb:

I stand corrected then, price increase time ;)

Hahahha :p
In any case would be nice to find if really the v3 sti has a more aggressive cams :o
It's quite easy to measure timings (a dial gauge and a protractor with the center hole enlarged are needed)... But it's quite time consuming :(
In any case, are one of the best performing heads.

Still available guys

Top for offers

top, no silly offers please but will happily take a sensible one :)

Amazed they haven't gone, very cheap price.

I know mate. These are great heads with low miles ready to bolt on.

If they are still around after x-mas (which i doubt) then i'd have them
