B16a2 Stage 2 Cam Question..

[Aaron1259]

I'm wanting to upgrade to stage 2 cams. I already have I/H/E. What else will I need? Valves and Valvesprings? Retainers? Throttlebody?

Also what is a nice affordable brand? I have been looking at Brian Crower, anyone heard/used them before?

Also is there much of a power difference between stage 1 and 2?

Thanks :)

What engine? B16A?

I recommend adjustable cam gears, springs and retainers, oem valves are good, ported head with matched manifolds, maybe larger TB/IM if you want (ITR setup is a nice upgrade for b16a).

Tunable ECU.

Stage differences depend on the brand. Skunk2 makes decent B-series stuff. Brian Crower is good.

Generally I think stage one is good for street driving so you dont have to completely thrash your car all the time to get the power. Stage 2 is probably fine though it depends on how you want the car to drive.


If I were you the first things I would do are an ITR 4.7FD GBox with OEM LSD, as well as a HD clutch/lightened flywheel setup. Probably feel better than a head build.

Also, having done a full head build myself, next time round I would rather just run the standard head but swap the block to a b20. Probably cost less too and go much harder down low.

Probably a good idea to bump up the compression a couple of pts..maybe thinner HG.

Or if you wanna go all out get get high comp pistons.

Need high compression to take full advantage of cams.

[dougie_504]

Just take a bit off the head when you port it IMO, leave the pistons alone for now.

[Aaron1259]

I added everything up to build the head, it seems alot cheaper to just go b20 bottom (or Frankenstein or something?) and my head, using some b16b/b18c internals? would that be better?

[jdm18c]

B20 would be better... Just keep in mind you have to get it engineered for insurance purposes

[dougie_504]

Find an engine builder to talk to about it mate.

Standard internals from a b16a head on a b20 will still rock man.

I'd just ask them to shave a bit off to bump the compression when they slap it together.

Just stick a nice size turbo kit on it =]

best option.

no point pissfarting around with N/a

unless you're a P plater.

[Aaron1259]

Yea I would like to stick a nice turbo on it, but you guessed it, I'm on my P's. Does anyone know any reputable Honda engine builders around Sydney/Western Sydney?
