Case in point I have a internally stock(bolt on's) healthy gsr and have some tuner 2 cams(springs+retainers already installed). Is it worth it to get it tuned with the cams or sell the cams and get some other things for the car. Comes down to is stock gsr compression enough for these cams or not worth the time/money spent on getting It tuned.

thx guys got the tuner 2 cams when I got the car so it's kinda meh to sell or keep them got the springs and retainers just for the hell of it.

 

If they are already installed then tune them. I've seen them make 180+ whp. A new set of 11 to 11.5 slugs will put you near the 200 whp mark.


It is a good start.

 

There good cams but with 10:1 Compression they won't do you very much good.
Much more beneficial when used with 11.15:1+ CR.
They could always just sit on the side and wait...

 

that's what I'm leaning towards they're just sitting in a box, never used. Got them last xmas on sale lol.

but swapping pistons is a bit above me still, so i'll see what I can get for them $ wise. have my eyes on some Megan EZ street coils.

thx guys

 

LMK if you do decide to let them go.
I'm somewhat in the market for a set of Stage 2's. No rush though.

 

since were sorta on the subject what would be an an appropriate cam choice for his c1?

 

DDtech cams have lots of hype right now and looks like they're well worth it.

I disagree.

OP if you already have adequate VT, your top end is going to improve tremendously. Your stock motor peaks around 7,5'ish? I bet these cams with an intake/header/exhaust will put you to 8k or maybe more. I say do it.

Question to you - what cam wouldn't benefit from added compression?

 

BC3+, Toda A and S2S1 would all be good choices.

 

A cam that sits in a box would not benefit from added compression lol

I too agree that if you have them, use em. You will make more power over stock cams. How much more is another question. But that's what a dyno and tuner are there for.

 

I know it would increase top end, tune costs around 550$ there's not much else I can do without touching the block afaik the head was shaved a bit but still stock gsr comp more or less. so idk may just do it instead of coils would be neat to see what the car puts down hp/tq wise

 

What are your bolt ons?

 

plm Bigtube header skunk2 exhaust skunk2 intake manifold w/70mm tb(port matched to ITM) PW:JDM intake and a chipped p28 from a very reputable shop around here. car pushes 230psi in all 4 cyl's

 

I would sell them get some 11.5 or 12 slugs and jump on some pro1's.

 

That header is absolutely terrible for you. I would sell it, use the money to put towards a Toda or Narrow. Then install cams, tune, then lower. It would also be nice to get a different intake but that header needs to be the first thing changed for sure.

 

but my only goal is top end so the header plus intake fits the bill no ?

it's also rather banged up from being low so it's not really worth much anymore.

 

No. Your transition into vtec using those cams with that header will result in a HUGE loss of power. You will have a horrible powerband...it'd be quicker in stock form.

 

I used these same stage 2 cams on an all motor 9:1 compression gsr that was setup for turbo, and ran 12.9 while using a victorX .

 

anyone else have input ? kinda looks like 50/50 atm

 

No it's not. Clean Rice is right, that header (as well as that intake) are known for creating huge dips in the midrange around VTEC. I run a 85x89mm build with 12.5:1 compression and I still wouldn't use that header. The Toda replica ***** all over it, at any point in the RPM range.

As far as the cams, yes you should tune them. If you understand how engines work, then you would know that by running those cams you are increasing the fuel required to the engine... and without tuning the car you are almost definitely running lean right now.

1. Get a new header

2. Tune the car

 

2LEM1, what header would you recommend ? My big tube is dented up
Pretty badly so selling it isn't an option so sub 500$ would be nice. Also the cams are just sitting in a box the car runs slightly rich not much but just a tad. Thx for your input.

 

out of the replicas the toda rep hands down. im also going to be running skunk2 tuner2 in my stock bottom jdm gsr but im going to run a 2 layer headgasket and hope to get from 10.6:1 to 11:1. I also have the toda rep header, kteller 2.5 inch exhaust, performer x intake manifold, 68mm throttle body, and a 3 inch intake going to a 3 inch velocity stack im debating on getting the head ported or just a good valvejob im trying to push as close to 200whp as I can without touching the bottom end. the only thing about tuner 2 cams that I don't like from past experience is the powerbands never really a smooth one most of the power is at 6k rpm and above leaving not much power below that so I may be switching the cams and selling my tuner 2

 

So would that be the "standred tube" tri-y header that is the toda rep ? Toda rep didn't turn up much on google.

Yes, the PLM Toda replica has continuously proven to outperform everything except custom headers. And the Skunk2 Alpha hangs with it, albeit with a slightly more lumpy midrange. I think the S2 Alpha might actually outperform it in the high RPM range. Like 9k+
