Not been in the scene for a long while, is jez still doing the modified CPU's? (Which is the simplest route to take).
Yea jez is still top banana, i wouldnt trust anyone else,
Sxoc isnt a ghost town, its a fantastic website, i spend most my time in s14 technical (under same board name) and theres always local meets in your area.
There was a big thread about spec R vs spec S and upgrading to spec R and i think the result was, its cheaper to buy a spec R in the first place.
Ive never understood the spec S, even with plans to upgrade to R performance. You could have always bought an s14 and modded it, or even bought it already modded and still had change and it will be a lot better then a spec s silvia.
If i was you,
I would aim for 300bhp which is fairly easy and quite cheap, and slap an auto diff on (3.9) im running this in my s14 and its a fantastic set up.
Visit apex performance and get yourself some coilovers (read about their stiffness, they have quite the range so you can buy a set perfect for your driving style and conditions)
Apex bushed adjustable arms are a good shout, i have these and cant fault them, i read they were a better buy then driftworks alternative but have no proof of this statement.
Everyone surjests anti roll bars, i managed to get god speed ones in a group buy, but i cant say wether they made much of a difference because i did my adjustable arms, springs, bushes and rollbars while it was off the road over last winter and when it was set up, the whole thing felt fantastic but cant pin point what did what, just the outcome of everything was awesome
