If you just had it tuned, it sounds like it's time to leave it and spend attention to the suspension.
If you touch the VVT or cams, you have to go back to the dyno for a tune again.

<div class='quotetop'>QUOTE (D86TOY_20V!nce @ Feb 11 2008, 07:15 PM) </div>I think it made about 87.9rwkw after he tuned it and yes he is very good. Car runs so much better than it did befor the tune.

<div class='quotetop'>QUOTE (Jonny Rochester @ Feb 11 2008, 10:57 PM) </div>I'm just researching at the moment. Just wanted to find out what was able to be done to the 20V as i have heard from people that you can't do that much to them. I will do all the work myself when i do it as I'm a 4th year mechanic.
Suspension is fair sweet at the moment but i need 5 to 5.5 kg rear springs as my 4.5kg ones suck balls. Gor coil overs int the front but could do with some sway bars to. Does anny one know of some one who has 5 to 5.5kg rear springs int the sydney-wollongong area?
I don't understand why people say that not much can be done, as much can be done as any other engine to a point. The main limitation in a 20V is the combustion chamber shape and the size of the buckets, this limits how big a cam you can go.
Also I forgot something, adding an angled spacer between the inlet manifold and the head will ggive you 10% more theoretical flow

angled up I'm guessing. Would have to get someone to make one up. I'm gessing it gives the air/fuel mixture a more direct flow?
yeah thats right and it has to be hand ported to work properly. It works because the 20v head has a suprisingly harsh angle from the manifold. Also its a seriously hard thing to make.

Have you got any pics of it done?
nope never seen it, I did recommend to someone to do an easier option which is make a thick spacer and then have it internally angled to take the sharp bend away which he went through with. I might be able to get a pic of that.

Yea that would be cool if you could.
