hi guys, i have a built b16 head port polished oversized intake valves, both intake and exhaust valves from supertech, supertech dual valve springs and retainers.

So basically i would like some feedback from different people who have used certain products on their setup, pros cons from certain manufacturers, reliability, price, and ect.

i know of alot of crazy all motor cams out there but not to sure of good turbo cams.

 

this topic has been covered a billion times. If you dont feel like doing a search, then I would say they all work and the end results depend on how they are installed.

 

CTR intake cam has proven good flow and power for FI, paired with a CTR exhaust cam or even a GSR exhaust cam.

As far as aftermarket, Ive heard a lot of cons but i have nothing specific to mention. Majority of high hp set-ups settled for the CTR cam and plus, its OEM honda quality.

 

skunk 2 pro1 allmotor cam is the in thing atm. makes great power too.

 

the cam you chose can make or break a setup. you get a small turbo with a large cam setup, and you are asking for problems. get a large turbo/small cams, and you run out of "steam" early.(will make power, most likely @ a higher boost number, but not carry it out)
large turbo/large cams, properly installed = big power, wide rpm range of power

 

Well said

 

ok well does anyone have the size on ctr cams or are they the same as itr?

 

the PRE-2000 CTR cams have the bigger intake cam compared to the POST-2000 ITR/CTR intake cams. the ITR,CTR, and GSR exhaust cams are the same size.

someone correct me if im wrong.

GSR cams are different on both intake and exhaust in comparison to the ctr and itr all years.

00-01 ITR are same as all ctr cams. 99 and lower itr are slightly different. i believe by a degree or two and very minimal lift difference

umm no. EXHAUST cams on gsr, itr, and ctr should be the same.

only differences are the Intake cam, in which 99 and years before the CTR intake is the largest type-r intake cam. After 99 the ITR and CTR intake/exhaust are the same spec.

 

ive had both ctr and gsr cams and the exhaust cams didnt seem the same to me i could be wrong though

 

i would like to know if anyone has done b16a2 intake cam and 00-01 gsr exhaust cam on their forced induction setup

haha what for ?

 

the reason is the gsr exhaust lobe heights are much higher than the b16 and the b16 intake cam is better than the gsr.

umm wrongo the both gsr cams are bigger than the b16 cams, plus the gsr cams have more duration.

UNLESS you ment to say you were using the JDM b16 cams which are bigger than gsr cams

 

You guys need to go do some research on these B-series cams. GSR, ITR, CTR, B16 cams are all different (CTR and late ITR are the simialr ones).

Like one guy mentioned above, small turbo medium size cams are ideal for the most part. Large turbo, big boost, bigger cams are ideal.

 

Took this from another thread. It's pretty much sums everything up as to which cam you should run. :

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by boosted hybrid &raquo;</TD></TR><TR><TD CLASS="quote">The skunk2 tuner series stage 1 cams work really really well. They are a bit bigger than the itr/ctr, make about 20-30whp more, are easy on the valve train/rockers (which alot of people dont take into consideration) and have stock idle/drivability and usually require no cam gear adjustments (as long as block/head have not been milled severely). The stage 1s seem to work well with turbos as small as the gt28rs and larger (just used them on a s372 and picked up ridiculous power over gsr's)

The skunk2 tuner series stage 2 cams work well from the two cars that i have used them on. Picked up 70whp over itr/ctr cams at higher boost levels. Are a bit harder on valvetrain/rocker wear, have stock idle and drivability. I would not run these for anything less than a gt35r sized turbo.

The skunk2 pro 1 cams are great. They need to be degreed in to idle/work properly. These cams usually pick up a little more midrange than the tuner series in boost (i.e make the turbo spool a little sooner). The idle/drivabilty is a bit harsher than stock, but once degreed and tuned its not that bad. Valvetrain wear is not bad with them either. I have seen gains of 40-50whp over itr/ctr cams with them. The pro 1s seem to work well in gt35r + sized turbos.

The skunk2 pro 2 cams are I feel too large for a turbo application. I have tested them on gt42r/s372 sized turbos and lost power over the itr/ctr cams. There was significant midrange gains with them compared to the itr/ctr cams, but there was about 60-70 whp peak power loss. The cams were degreed into the engines properly.

When picking a cam, think about valvetrain wear and seat pressure. Alot of the aftermarket springs do not have the seat pressure to run a higher lift all motor cam, as well as 20-40 psi of boost pressure. Also, the biggest cam does not always work. Its a compromise. I have been using skunk2 products for awhile now, and I would not even think about using another companies cams for the b or h series engines. The reliability, durability and power are awesome.

these are some turbos that i have seen making very good power with theses cams..

t3/t4 50,57,60 trims----- CTR,ITR cams
gt30r,----- CTR, ITR, skunk tuners stage 1 cam
gt35r/gt42r,----- skunk tuners stage 2 cams or Pro 1 cams

So is this really true? I have a JDM B16 Sir II and when I boost it I was going to opt for the GSR cams but now I am not sure that it would be the better choice?

 

GSR cams will make 800+ whp. I didnt have any luck with aftermarket cams but alot of that could have to do with my stock head/log manifold combo.

JDM B16B i what you mean correct? b16a cams are the same reguardless of jdm or usdm

 

To the OP, you need to tell more about your setup.

The turbo manifold will have a huge impact on cam choice. The biggest cam you can run on a log manifold is an R cam. Anything bigger than that and you'll have issues. IMO Gsr cams seem to work the best on log setups.

 

ok tony i'm wrong on the b16 intake being bigger than gsr intake on one thing cuz the 2ndary lobe on b16 cam is little bigger than 2ndary lobe on gsr (intake) but the gsr exhaust IS bigger than b16 exhaust~ but i don't need to spend money on both so i'm just buying the exhaust gsr cam.
