Quick update on her progress.
After some major googling it seems the best all round intake setup for the 70 is a decent panel filter and some intake hoses. The US forum has proved a 3-5bhp increase over the majority of the rev range vs a stock system, this was back to back on a dyno. The standard intakes are ridged on the inside and also have a resonator attached to the passengers side which all reduces air flow.
The Stillen Gen 3 definitely makes the most power but only high up the rev range. There is also the vast difference in cost between the two setups, so this is how I came to my conclusion. I went for HKS panels but you cant see them as they are sealed up Anyway enough babbling....
I was surprised how much difference this made, car seems to pick up revs a lot quicker and makes a nice deep noise above 4k.
Also had the car lowered on Eibachs and a full geo setup. I am running -1.5 degrees on the front and -2 degrees on the back.
Car is filthy so apologies!
Front lip is now very close to the ground. Less than my fist! Car seems very planted but I am yet to give it a full shake down
