3000gsk vs.4000gsk
 

what i'm wondering is if i don't get valve springs and i get the 4000gsk,i've heard not to turn over 3200 rpm's how hard is it not to do?and if i get the 3000gsk,won't that give me close enough being able to turn 3000 rpm's,whats another 200?and mine when it gets wound out it pauses as it shifts like it wants another few rpm's before it shifts,will the kit fix this?

the 3000 kits is more than most would ever need

Ok. i have the 4000 kit. I can feel a big difference in the low end as well as the top end. the 4000 fuels much harder and you have to be an asshole to go over 3200. you don't need it till you have the mods for it, and the hd valve springs. If you hammer your stuff with no care in the world then i would say do the 3000 until you get the 60lb sprrings. if you can moniter your foot control. you will have no problem and you can have the 4000 before the 60lb springs. you might as well not waste your time putting in the 3000, cause your just going to want the 4000 in a few weeks of driving. It's really all up to you. the 4000 is way better, you can feel the differnce from low end to top. I really never go to 3000 rpm with it anyway. only when i am racing someone. but i have the 4000. i coulnt see reving that high with the mods i have. it would be starving for fuel. Good luck, its a fun instal and you will like it. TAKE YOUR TIME

Go with the 4Ks and be done.

i have the 4k but hardly ever go over 2200rpm

im like him ^^^ but occasionally ill go to about 3... ive got 4ks btw

I dont even know if I have springs but I go to 2800-3k often.

you have atleats 3k if your going that high with stock springs you cant turn more than 2500rpm, atleast mine wouldnt

im pretty sure my motor doesnt have any gsk upgrades and mine will turn 3 no prob.

your motor dont have springs anyway there in your fuel pump, thats wierd thow since there designed to defuel at 2200rpm with stock springs
