I thought this thread is supposed to be about tuning the v6..
http://www.regal-shop.co.uk/asps/ShowDetails.asp?id=1885I have no idea if this could work, but might be interesting to use the 3.0 throtle bodie and intake.
regal offers a 25% bigger throttle and flowed intake for 325. its supposed to add 15% torque. Im VERY intrested in this for my 3.0 since the larger throtle bodies might go perfect with a set of mild cams. Ad a chip, and the fact that im getting my fuel injectors cleaned, ngk platinum sparks (need to find new leads) and i think i should be doing quite well. there is a tune shop 50 bucks per dyno run.. i dont know if its worth it. but if i decide to get my exhaust manifold done out ill talk em into giving me a few free dyno runs....
these are my plans.
IF i could swapp my trany to a manual I would def go all out on this car. I LOVE THE WAY IT HANDLES. I just test drove an 07 impreza and VW GTI and i swear, my catera out handles them both. heck, it out handled the impreza by a long shot. I dont know why maybe its my driving style but i think the omega is very much worth tunning and we need to make a demand for the parts.
ITs sex factor alone is enough of a reason to tune them out.
If one person got a custom exhaust manifold machined it would be expensive one time, then other people could order them cheap. Maybe look around see if a shop is willing to design one and then sell a lot.
