Rockers for a '92 VP V6

[Cobez]

Hey guys, i rang Yella Terra the other day about some rockers i want to purchase, now i took down my engine number etc and we figured out which ones i should use which are a 1.8 ratio rocker.


But i see alot of people are buying 1.9 ratio rockers.

Is there any major difference? What difference should i expect to feel?

My car has: pacemaker headers, 2.5" exhaust into a straight through muffler, re tuned chip, stage 2 shift kit, CAI, standard cam, but by the time it's time for the rockers to go on i will also have 3:7 gears, LSD, transmission cooler, 70mm TB with polished elbow and no bellmouth.


Cheers

most ppl seem to buy the 1.95 or 1.9's i guess because they have more lift and u get that extra bit of power. i wanna know if the 1.9s will be ok when i get an aftermarket cam or wats the story there

[hakhawk]

are they making a 1.9 for the pre ecotec yet? i didnt think they were

[beefcream]

from their website it seems they are for the series 2 v6
Yella Terra - Part details

not the series 1 tho which is bad news for me

[hakhawk]

thought so, thats s2 "buick" which is equivalent of the ecotec. if you goto holden and choose v6 3800 s1, theres only 1.7 and 1.8 listed.

[ephect]

yeap only 1.7 and 1.8 for the buicks and up to 2.0 for ecotecs (FIT were testing 2.0s)

[Emackulation]

Looks like 1.8 are the go then.

[Cobez]

Looks like it!


Cheers for the help guys!
