Compression for K20 w/ TODA A2 cam
My brother who has a JDM DC5 ITR just bought TODA A3 cams together with TODA valve springs. He will be using a Hondata K Pro to tune it. We want to know if you guys have used this cam before and if there are any suggestions for the ideal compression needed to maximize the cam. The cam seems has big lobe specs of 12.5. But the primary lobes are quite mild and are around 8 I think. The car has a AEM V2 intake and a TODA header and Fujitsubo B pipe and exhaust. I feel that the stock 11.5 compression will be fine for the cam but any feedback would be highly appreciated. Thanks for any inputs.
Wrong title, typo error. He got A3 cams and not A2.

i think the 11.5 will be fine too, but you can always mill the head a little or run a thinner head gasket to squeeze a little extra compression in there, and/or use flat-faced valves.
my opinion, just stick with what you got and tune it.
how's gas in the PI, pare?

We have 95 RON but not sure if its euro or us based. If its euro then the equivalent would be 91 I think. But a lot of guys running 12 comp ratio using the 95 and they seem ok. The distributor was offering a TODA headgasket which would bump up comp to around 11.9. Would it be worth it?
