Hi,

 

i'm looking for new camshafts for my 2,2na. Currently in my engine:

With 65er throttle body and dibilas flowtec inlet manifold 197HP and 225Nm. Next year my engine get a ITB Kit. 

 

What camshaft should i take?

Long time ago but it sounds as though you've had more luck getting BHP increases from the Dbilas Intake Manifold than we have experienced here. It's a nice looking piece of kit but, in my early (wasteful) days of trying things, that manifold along with Milltek exhaust, Piper cams and other bits struggled to give 180BHP. Back then the Piper cams were re-profiles and wear was severe after a short time. IIRC with 12 months I was only seeing 165bhp on the same RR in similar conditions. Some reported good results with Schrick cams although I've no experience with them.

compcams stage 2 or stage 3 should be fine 

 

dbilas are a stage 1 cam

vocky, stage 3 for street and torque under 3500 inadvisable?

I have been running stage 3 cams for years, not a problem with throttle bodies

For the road I would stick with the 2.4l manifold rather than ITB's. It will sound rubbish but you will have more power and torque up to about 5,000 rpm then the ITB's will take over. With Schrick cams the 2.4l manifold was better than the Dbilas back to back on my car. The Dbilas gave a low rpm torque peak which suggests to me the runners are too narrow, it did sound nice though. I run OBD Tunner with the 65mm TB and a similar spec to yours Frank.

I'll know if you're right or (hopefully) wrong about the ITB's by the end of the week

Don't get me wrong I think the ITB noise alone is probably worth sacrificing a little low down power. My conclusion was based on Fabs graph vs mine but only by comparing cars on the same dyno would prove this. Looks like you need some of Vocky's mods to get the low down power and torque back. Get a vid up when it's running. You should improve on your previous setup.
