my car is boosted and i was thinking about picking up this head that comes with ITR cams..or maybe just keeping my gsr cams and keeping the price down on the head purchase. it has croler valvs springs and retaners.i allmost think it wold be pointles to have the valve train upgrade if im only going to have gsr cmas.

also i have heard that its harder to tune with ITR cams over GSR's

Finland

It's impossible to use ITR cams with boost...

i think boosted hybrid had something on his website about 40-50 hp gains with itr cams over gsr cams, but the motor was making a few hundred hp to start off with.

itr cams + boost =

im trying to score my friends b16 head and do myself an ls/vtec, mainly because i can use the cams

While we are on the subject, how about itr cams/retainers/springs w/jrsc?

tonydatyga

gotta dial out some overlap w/ the exhaust gear

kell211

i think you'll find that either of those are excellent for boost. the gains boosted hybrid found were gains from adjusting the cam gears, not gsr cams vs. itr cams. and he was having to dial "in" overlap, not out. But, that was for cars with a log manifold and restrictive exhaust. If your running and equal length manifold and 3 in. exhaust, you'll find little to no gains from adjusting the cam gears.

This is what Jeff replied in my question regarding type r vs. gsr cams...

" Type R cams--they make way more mid-range and carry the torque way longer than the GSR's."

As far as cam gear adjustments they will benefit every setup differently, but I think its fair to say that regardless of manifold style, decent gains can be had.
Here is Ron's 4dr integra with an equal length manifold. He picked up nearly 70-80 whp from gear adjustments.

and another... big power gained on a Equal length with gear adjustments

i have personally seen a 23hp gain with ITR cams over gsR cams with just a tiny bit of tuning and time, im sure there was more to be had.

remember ITR cams pull all the way to like 8500, the same place most of us rev our turbo acrs out to, but these make better power out that far

BoostedEG6

Alot of people I know running the ITR cams are running only the intake cam because the GSR exhuast and the ITR exhuast cams are the same so dont waste the money on the exhuast and just get the intake cam from the ITR

Cloner

No they are not the same.People run just the intake cam so they dont have to change valve springs.Here are the specs.

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.

Following cam measured with 0mm of lift:
Civic Si(1999 Spec)
Int-265 dur. / 10.5mm lift
Exh-267 dur. / 9.6mm lift

Integra GS-R
Int-274 dur. / 10.7mm lift
Exh-276 dur. / 9.6mm lift

Crower 400
Int-279 dur. / 10.7mm lift
Exh-280 dur. / 9.6mm lift
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.

Civic Type-R And Integra Type-R(Integra Type R 2000/01 Spec)
Int-278 dur. / 11.5mm lift
Exh-280 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.

Crower 401(NA Version)
Int- 282 dur. / 11.3mm lift
Exh-277 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. Crower Valve Springs can also be used.
Description: This cam is almost identical to the Type-R cams. A little more duration overall but that is traded off with a little less lift on the intake cam. They will have similar gains and powerband as the Type-R cams. If it were up to me I would just choose the Type-R cam based on reliability alone (there is that ?r? word again). These cams will have stock idle characteristics. I would recommend using Crower cam gears with these cams.

Crower 401-T(Forced Induction Version)
Int-280 dur. / 11.8mm lift
Exh-276 dur. / 11.3mm lift
Valve Springs to be used: Crower.
Description: One of the only true boost cams for B-Series Hondas on the market. This cam is designed for low overall to prevent blow-by and to save boost. This is typically associated with lower duration and high lift but cam lobe separation is also a factor with these cams (thanks Clayton). These can be used in a NA car but they will see better gains from a cam set with more duration. Stock idle characteristics are attained from my sources. I would recommend using Crower cam gears with these cams.

Toda Spec A
Int-290 dur. / 11.6mm lift
Exh-280 dur. / 11.2mm lift
Valve Springs to be used: Integra Type-R up to 8800rpms or Toda valve springs for all operations. These cams are wild enough that you should not be using the low 8200rpms rev limit.
Description: One of my favorite set of cams. Toda does not actually mix and match their cams but they are similarly tied when it comes to power. The Toda A will offer the midrange gain of a Type-R cam but the high-end gain of the Toda B cam. These cams will have gains from midrange to 8800rpms with peak gains concentrated on 7000-7800rpms. These cams are great for a street motor and are really nice for cars equipped with a stock B18C5 motor (no valvetrain or ECU requirements needed). These are the only Toda cams to retain stock idle characteristics. I recommend using Toda cam gears with these cams.

Crower 402(Both Regular 402 and 402-A, 402-A is milder off VTEC)
Int-297 dur. / 11.8mm lift
Exh-287 dur. / 11.8mm lift
Valve Springs to be used: Crower.
Description: There are two 402 versions offered. The 402 is the regular version and offers better midrange power than the 402-A. Both are similar on the high end of the cam and will create similar peak power numbers. They will make peak power around 7900-8200rpms and have nice gains all the way up to 9000rpms. Stock idle is attained with the 402-A but the regular 402 will have a slightly ?bumpier? idle than stock. I recommend using Crower cam gears with both sets of the 402 cam.

Toda Spec B
Int-295 dur. / 12.0mm lift
Exh-285 dur. / 12.0mm lift
Valve Springs to be used: Toda but Port Flow will work well too.
Description: My personal pick. These cams have the most midrange gains out of any B-Series cam when they are tuned right. They have the same midrange gains of a Toda Spec C and the same top end as the Toda Spec A. They are in tight competition with the Skunk2 Stage 2 and JUN Type 3. Those care are more concentrated on top-end, peak power gains. The Toda B is more concentrated on midrange power with the tradeoff of a little top-end power. Toda B?s have great gains from 4500rpms all the way to 8800rpms. Power does start to dip off quickly at around 8400rpms though. Due to the wild off-VTEC profiles, these cams do have a ?bumpier? idle than stock. I recommend using Toda cam gears with these cams.

Crower 403
Int-295 dur. / 12.0mm lift
Exh-293 dur. / 11.8mm lift
Valve Springs to be used: Crower.
Description: Crowers wildest cam. The 403 has good midrange of the 402 cam but with a little more top-end power. They will make more power above 8200rpms than the 402 cams. Like the 402, the idle will be ?bumpier? due to the aggressive non-VTEC profile. I recommend using Crower cam gears with these cams.

Toda Spec C
Int-295 dur. / 12.5mm lift
Exh-295 dur. / 12.5mm lift
Valve Springs to be used: Toda
Description: The ultimate cam. This cam mixes the midrange power of the Toda B cam with the top end of similar to that of the JUN Type 3 and Skunk2 Stage 2. Power gains from 4500rpms all the way to 9000rpms. This is truly, the best overall cam for both midrange and top-end power. They might not give the top-end gains of the Skunk2 Stage 3 but you get more midrange and these cams can be used on the street with the right set-up and the deep pocketbook. Due to the crazy off-VTEC lobes the idle is rougher than stock, just like the Toda B cam. I recommend using Toda cam gears with these cams.

Toda Spec D/Ericks Racing
Int-305 dur. / 12.9mm lift
Exh-315 dur. / 11.9mm lift
Valve Springs to be used: Yet to be determined. Probaly Toda or some custom spring
Description: Yet to be anaylzed. Probaly going

hrmmm i personally seen a 30 WHP decrease AFTER tuning for both setups on the SAME motor.

made 330 WHP at 13 psi of boost tuned

same setup with gsr cams afterwards only m ade 302 WHP to the wheels. tuned

Info on 00 Si to 96 Spec ITR cams 37whp at 8700rpm increase and total of 53whp total

Cloner

Only way to find out is to dyno with gsr cams then switch to type r's.Going from 00 si cam to type r will net more than going from gsr to type r.Less duration more lift
