Hi, I have been speaking to Guido from Crespo Cams, and have got a quote for some cams for my 206 GTi. I'm not too sure on what gains can be had doing this, but I plan to combine this with ITBs in the near future (I have the cash and time to tack a set together from a new ($500) set of honda S2000 ITBs and a custom manifold.)
Here is the info on the cams.
USD 650 + USD 120 shipping
For comparison, I saw this info on a Cat Cams which claims a 23bhp gain with a piggyback ECU (I have one which I will be installing when I get time).
I was just wondering if one of the NA tuning experts on here could help with an estimate of the power gain from the Crespo cam, the ITBs alone, and what I could likely acheive with the cam and ITBs. My goal is 200bhp, but I'll be happy with anything over 180. Is there anything else I'll need to do to get there?
Also I've heard that a lot of BTCC and similar teams use the stock exhaust manifold because there is no better option. This doesn't sound right, as it looks very compact and is not a 4-2-1 design. Is this a myth or is there a reason that a simple manifold like this works so well?
