ecotec cam and rockers

[lo-rolla]

hey guys,

is there a good grind for a ecotec? or a specific grind? like common good grind for the 304 is 286
and whats the deal with the hi ratio rockers? can i still use them with a big cam? just not a big ratio?

cheers, Ben.

there are plenty of grinds for the ecotec, hit up come racing or crow cams (awaits flaming), with the rocker ratio you need to encorporate that into your cam selection, normally if you are going a big cam, a higher ratio rocker isnt really needed.

Every thread i have seen come up about this subject the wade 992a gets a high recommendation, best bet is to wait till someone who knows about this stuff comes online/see this thread

[vn calais manual]

992a, for the ecotec?

[padrickz88]

for both ecotec and buick

[lo-rolla]

spoke to come racing they reccomended:

CSBR523
LIFT: 533ex 507in
ex 232@.050 in 222@.050

needs 10.1 comp tho, and rpm range 3,000 to 6,000

also, crow and and come both said dont bother with the high ratio rockers as for there really designed for standard cam.

this is a bit bigger than the 992a grind, but im sure would be a nice size on an ecotec motor, if you are retaining the standard rocker ratio.


yes the higher ratio rockers are normmaly used when keeping the original cam profile.

[sircruisealotVS]

sheesh, that cam that c.o.m.e. recommended is a decent size...maybe a little too big for a streeter. what are your plans for the car?
if its only really a daily driver then i'd go just a little smaller than that or your going to be revving the tit's off it to get moving.
was it a hydraulic roller cam? if so, must be one of the biggest they make. you definately want a hydraulic roller if its a daily driver, way too much bullshit messing around with a solid.

it is way bigger than a 992a
i would say the 992a or 1114a would be around the right size for a street driven ecotec (both are smaller that that c.o.m.e. cam).

i second that... dont get a cam that is too big if you are goin to drive it on the street. It can get annoying sometimes!

and you will need some sort of stally or else it will be an absolute pain to drive

I've been doing a tune for a well worked V6 with a 1114a12 lately, still have a way to go till it's right but he had it idling on the phone for me to hear the other day and it's not short of note at idle I can tell you

[lo-rolla]

been doing a little more research and checked out the wade 1114a camshaft. sounds like they way to go. will call them tomorrow and get a price on it.

[lo-rolla]

just another question about the wade camshaft (1114a) i rang them and there main guy is away, so he's not sure if the 1114a is a re-grind or a billet cam?

does anyone know?
and yes, the wade one is a hydraulic.

[padrickz88]

pretty sure the biggest you can go on a regrind is the 992a, could be wrong but :P

[lo-rolla]

Cheers,

i said (and so did the bloke from wade) that it's probly to big to regrind.

hi. i have no idea about cams lol. nice start, but i have a vx executive 3.8L manual. how much gain would i get from a cam upgrade and how much are they and where from? lol thanks heaps. seems like the best place to go to get any help

[TrEnNaVY]

so i got a vy s pac v6, worth getting a 992a on it? i got a mate that just started at crow cams so i should be able to get a good price.
