Following Cams Measured at 1mm of lift:
Integra Type-R(Through 1999 Spec)
Int-240 dur. / 11.5mm lift
Exh-235 dur. / 10.5mm lift
Valve Springs to be used: Stock B16A/GSR if using stock 8200 re-limit. Integra Type-R if using rev limit over 8200rpms. Mugen Valve Springs can also be used.
Description: These are great, reliable cams for the money. You can pick up a set for as little as $500.00 new if you are lucky! They will give good gains from midrange all the way until 8400rpms. These cams have stock idle characteristics.
Civic Type-R And Integra Type-R(Integra Type R 2000/01 Spec)
Int-243 dur. / 11.5mm lift
Exh-235 dur. / 10.5mm lift
Valve Springs to be used: Stock B16A/GSR if using stock 8200 re-limit. Integra Type-R if using rev limit over 8200rpms. Mugen Valve Springs can also be used.
Description: These are great, reliable cams for the money. You can pick up a set for as little as $550.00 new if you are lucky! They will give good gains from midrange all the way until 8400rpms. These cams have stock idle characteristics.
Skunk2 Stage 1
Int-252 dur. / 11.5mm lift
Exh-249 dur. / 10.8mm lift
Valve Springs to be used: Stock B16A/GSR if using stock 8200 re-limit. Integra Type-R if using rev limit over 8200rpms. Skunk2 Valve Springs can also be used.
Description: These are very underrated cams. They do cost around $100-$200 more than the Type-R cams but they also offer much more duration and will give more power than the Type-R cams. Similar power range of Type-R cams but stronger throughout the power band. This is a great set of cams for a budget minded B16A owner. These cams have stock idle characteristics. I would recommend using Skunk2 cam gears with these cams.
JUN Type 1
Int-265 dur. / 10.9mm lift
Exh-268 dur. / 10.0mm lift
Valve Springs to be used: Tough to say. I have never seen anyone use this cam. The characteristics say that a stock B16A/GSR valve spring could handle these cams for use up to 8200rpms. Any operation above that and I would use ITR valve springs or even JUN valve springs.
Description: Again, I have never seen these used. I have no clue on the power these cams will deliver but it should be similar to that of a Skunk2 Stage 1 cam, although they are very different cams. These cams have stock idle characteristics. I would recommend using JUN cam gears with these cams.
Spoon Sports
Int-256 dur. / 11.5mm lift
Exh-245 dur. / 11.1mm lift
Valve Springs to be used: Integra Type-R. These cams are wild enough that you should not be using the low 8200rpms rev limit. If using these cams past 8800rpms(why would you) I would think that Port Flow or even Toda valve springs would work but I don’t think these cams will make much power after 8400rpm.
Description: Another somewhat rare cam. Will show definite gains over that a Type-R cam and very good gains on a stock B16A/GSR motor. Stock idle characteristics from the few users I have seen use them. I would recommend using Spoon cam gears with these cams.
JUN Type 2
Int-267 dur. / 12.0mm lift
Exh-265 dur. / 10.9mm lift
Valve Springs to be used: Integra Type-R up to 8800rpms or JUN valve springs for all operations. These cams are wild enough that you should not be using the low 8200rpms rev limit.
Description: Another rare cam but a few people have used it including JSIR. Cams will have just as much midrange gain as the big-brother JUN Type 3 but will start to slack off over 8400rpms when the Type 3’s are still making power. However, this cam will cause fewer headaches to get right and does not require the fancy valvetrain and tuning of the Type 3. This is by far the most underrated cam of this whole bunch. These cams have stock idle characteristics but still offer better midrange power than the JUN Type 3 (start making power at an earlier rpm) . I recommend using JUN cam gears with these cams.
Skunk2 Stage 2
Int-266 dur. / 12.3mm lift
Exh-262 dur. / 11.8mm lift
Valve Springs to be used: Skunk2 preferred but Port Flow will work as well. These cams are wild enough that you should not be using the low 8200rpms rev limit.
Description: The new top dog of the cam world. This will become the most common aftermarket (non OEM) cam in the US when they start getting distributed more. These have a very similar power band as the JUN Type 3, with less cost and better reliability (I said the “r” word). Not huge midrange but very good gains from 7000rpms all the way to 9000rpms(peak is usually around 8000-8200rpms). These cams have stock idle characteristics, thus making them the ultimate street/strip cam. I recommend using Skunk2 cam gears with these cams.
JUN Type 3
Int-265 dur. / 12.0mm lift
Exh-265 dur. / 11.5mm lift
Valve Springs to be used: JUN preferred but Port Flow works as well. These cams are wild enough that you should not be using the low 8200rpms rev limit.
Description: Until the Skunk2 Stage 3 this was the best high-end performing cam on the market. The JUN 3 and Toda B were the two fighting out for the top dog when it was just JUN and Toda (ahh the old days). Again, like the Skunk2 Stage 2, not huge midrange but very good gains from 7000rpms all the way to 9000rpms. These cams have stock idle characteristics, thus making them the ultimate street/strip cam. I recommend using JUN cam gears with these cams.
Skunk2 Stage 3
Int-270 dur. / 12.8mm lift
Exh-279 dur. / 11.8mm lift
Valve Springs to be used: Skunk2.
Description: A race only cam. Not to be used on the street, if they are you should pull the head every oil change to make sure everything is OK. This cam makes huge top-end power gains but still retains stock idle characteristics (weird). This cam is or has been used by Skunk2’s drag racing team and Speed World Challenge team as well. I recommend using Skunk2 cam gears with these cams.

Exh-276 dur. / 9.6mm lift
Crower 400

Valve Springs to be used: Stock B16A/GSR if using stock 8200 re-limit. Integra Type-R if using rev limit over 8200rpms.
Description: This is a weird cam. I would call it an OEM replacement cam. It fits in between stock B16A/GSR cams and Type-R cams. There are not huge power gains to be had with these cams but you may notice a small difference. These cams have stock idle characteristics. I recommend using Crower cam gears with these cams.
