If i drop a GSR B18C (Which is cheaper then those Spec R).... Should i change the Cam shaft ? ? ? ? ? change one which is for a B18 or a B16 ? ? ? ? ? ? ?

Which brand of cam shaft you people prefere ? ? ? Type R Cam ? ? Toda Spec B Cam ? ? or any better recomendation ? ? ?

Type R is better there noob.

I guess if you are looking for a "drop in and go" cam, than the CTR/ITR cam
would be the way to go.

If you want some really aggressive cams (ie Skunk stage 2, JUN 3, or Toda B)
you must upgrade the valvetrain, and either run Hondata or get a re-chipped ECU to extract the full potential of these more aggressive cams.

get the ITR cams, but if you plan on building then get the JUN, TODA or SKUNK2..

If you drop a gsr motor in the car, I would not change the cam untill you decide if your going all motor or FI. Then you can choose the one that makes the most power for your setup

Thanks aLL for the reply

i think i gonna save the $$ on the engine swap(just change the cam shaft of my B16a) and use it on a drag 3 turbo kit good idea ? ? ? ? ? ? ? ?

one more question is i wanna build up the torque at around 3000 RPM . . . sOo which cam shaft is more to the mid torque range ? ? ? ? ? ? ?

Why are you saying change THE camshaft?

You know that there are TWO camshafts in the GS-R motor, right?

Unless you plan on upping the compression by gettigna really thin headgasket or getting higher CR pistons, Toda B cams probably won't be all that great nor will the JUN 3 nor Skunk2 Stage 2 cams because they are designed for higher CR than any GS-R motor has stock.

USDM B18C1 from GS-R: 10:1 CR
JDM B18C from SiR (GS-R): 10.6:1 (Same as USDM B18C5 ITR motor)

Good drop in cams w/o upping the compression?

I'd think Skunk2 Stage 1, Toda A, or CTR intake cam and whatever exhaust cam.

VtecApprentice

Thankz fOr all the advices but i don't really understand yYy issit that you all advise me to get the Jun 1 or TODA A cam and not the Jun 2 or TODA B cam ? ? ? ? ?
Don't these second stage cam shaft produce better timing on the valve ? ? ? ?
Can someone please explain to me what is the different between the 2 stages of cams please ? ? ? ? ?

I'm thinking of dropping ITR cams in my gsr motor....do you guys think i'd get noticeable gains untuned? As of now...i can only afford the cams...but still gotta save up for say a hondata 2 unit

type r cams and chipped ecu

hEy tHanKzZ aLoT dUde i really learn alot here

from the way you said . . that means if i wanna make the most out of it i should upgrade the whole valve train before swapping a better performance cam ? ? ? ?

Any recommended valve train please ? ? ? ? ? ? ?

Again I will state that in order to get the most out of the Toba B, JUN 2/3, and Skunk2 Stage 2 cams you will NEED to nump up the compression.

These cams were desrigned for motors with like 11.5-12.5:1 compression, and a B16A or GS-R motor is nowhere near those numbers.

No offense, but unless you have the money to pay someone to build your motor I would try to stay away from upping the compression and running the big cams listed above.

Building a bottom end is a delicate process that takes a lot of patience, know-how, the right parts (hard to find sometimes), and time.

If you aren't sure how to build the motor, then simply leave it alone.

Again I'll recommend the Skunk2 Stage 1, Toda A, SPOON (about the same as Toda A), and JUN 1 cams.

I have seen people run the Toda B cams on a stock CR Type R motor (10.6:1 here in the U.S) with minimal gains when compared to what I've seen out of a set of Toda A cams.

There's a guy on H-T who goes by the name of kenji who got 190whp out of his stock CR B18C5 with Toda A cams, a thinner headgasket, i/h/e, and his P28 ECU.

I know a few people who could not even get 185whp on stock CR with Toda B cams.

You can't just throw parts together when building an engine, and throwing radical cams in an otherwise stock motor might yield some gains, but they might not be as good as the gains you'd see from cams that were DESIGNED to be on lower compression.

Oh, and the question of valvetrain:

For anyone reading this that wants good, cheap valvetrain go get this stuff:

Go to your Acura dealer or a website that sells genuine Honda/Acura parts and order a set of ITR INTAKE SIDE OUTER valvasprings.

Then go to http://portflow.com and order their STIFF INNER valvesprings.

This combo has been shown to be able to hold revs above 9500rpms w/o coil bind. They can handle any cam that you can throw at it too.

Last thing I'll say in this post is that you cannot just throw in a set of cams or a CTR intake cam and expect gains without tuning it.

If you put cams in the motor without tuning it you could actually LOSE power, so why not spend the $150.00 or so and get the motor tuned on a dyno with a wideband 02 sensor?

Later.

Thanks alot B18C5-EH2 i'm very apreciate that you take all the time to type out the message. I will keep what you said in mind

But i got another question again to increase the compression ratio . . . issit to increase the displacement ? ? ? ? or which part that i can change to increase the compression ration ? ? ? ? ?

VtecApprentice

From your this message you have already answer my previous question Sorry for missing it and ask you again u no need to retype everything again

I really apreciate what you have thaught me tHanKzZzZZ aLoT B18C5-EH2

VtecApprentice

U mean the Port Flow Design, Skunk2 or Ferrea valve String ? ? ? ? ? ?

VtecApprentice

? ? ? ? ? ? ?

Sorry to keep irritating you with this question but i'm really very keen in finding out cos i dun wanna make mistake in ordering
