I have a gsr motor running itr valves and valvetrain running skunk stage 1 ang spoon jdm itr pistons 11.3 to 1 . Do I need upgraded valvetrain for buddyclubs? If I do get valvetrain such as rockets I might just get skunk pro 1's but rather stay milder

 

I want to know the same thing? anyone itr valvetrain with bc3's ??

 

Omni, Supertech Medium, or RM G2. You'll be

 

no, havent try itr valve springs with bc3 but i did tried itr valve spings & retainers with sk2 stage 2 cams b4 & worked fine.Though i never rev it past 88000 rpm.

well, if thats the case then you should be perfectly fine with ITR's, thats what i was planning on running with those camshafts.... they're not that aggressive really, especially the lift. Youll be fine, run ITR's and save your money

 

Did you just go with the itr stuff?

 

id rather invest on good valvetrain such as rm g2. you might need it later anyways...and its better to be on the safe side

having too stiff of a valve spring isnt a good thing i was always told, only makes the motor that much tighter which in turn makes the motor slower, im almost positive youll sacrafice hp if you have too tight of valve springs.

help me out here if im wrong... ?

I don't think that's really the case. I think too stiff of valve springs creates more stress on the timing belt, shortening its life. I could be wrong about that though.

Anyway, what are the specs on those cams? If I were you, I'd upgrade the valvetrain just to be safe. It won't be too stiff. If I remember correctly, BC3's are in the same league as Skunk2-2's and Toda B's, and both companies state that an upgraded valvetrain is required to properly run the cams. Would you rather spend a few hundred on a valvetrain, or spend much more in the case of bent valves and the damage that could happen because of them?

 

too stiff can put excesive wear on the rocker pads etc. but what is too stiff? i wouldnt know.. i have supertech springs and they seem really stiff

 

i heard they were even compatible with the C1 valvesprings??? i remember buddy clubs claims they did a test with a stock GSR......and this cams is mild cams so high rev won't b nescessary...riight???

 

keep your itr outers, buy some alaniz or portflow inners and their retainers as well.

that will be your cheapest way to go, and you'll have an alaniz aka portflow valvetrain.

 

spec 3s are compatible wit stock valvetrain... 3+s and 4s require valvetrain upgrade
