- If I use warm cam, Do I need to uprate the valve springs? What's available options I can use?Hi ThanosK, thanks for reply! Seems like quite practical modifications to do. Few questions:
- If I use warm cam, Do I need to uprate the valve springs? What's available options I can use?
- Is weber DGAS has compatible base with standard intake manifold (i.e. can plug and play)?
Thanks again!
It depends on how warm you go. The profile below gave a pretty good bump, around 8 bhp. For that, you can use the stock springs. If you go warmer, you should use springs from a Peugeot 405 Mi16 shimmed to 38mm. In reality, you are limited on how warm a cam you can use by the XN1 head which does not flow very well. Using an XN2 head with four ports opens up many possibilities, but I would question the need to do that for a daily driver.

A number of AFers have used a Weber 34 ADM with great results, here is a link: https://www.aussiefrogs.com/forum/index.php?threads/and-yet-another-improvement.28313/
