Rockers for a '92 VP V6

Cobez · #1 27-01-2008, 04:03 PM

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

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

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

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.

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

Looks like 1.8 are the go then.
