I got my opti from a 95 in today, and am trying to install it now. I installed a new style timing cover and cam dowel pin. The pin on the back of the new opti is WAY to large to fit inside my camshaft!!! is there some way to use the old splined pin? do i cut it off or what? PLease help!!! I am supposed to go to a car show in 4 hours so i need to get this done ASAP!!!
Re: Need Help ASAP!!! New style OPTI (Nathan Plemons)
well, i wish someone would have mentioned the cams themselves are different between 94 and 95:smash: , and not just the dowel pin. Is there some way to retrofit the new and old optis together? i am in to this project a few weeks now and this could make it take a lot longer!!
could i install just a hot cam, and add roller rockers and springs later:confused:? i am kind of hurting for cash right now!!!
Re: Need Help ASAP!!! New style OPTI (Nathan Plemons)
Alright. The stock cam is listed as 202/207 .450/.460 116 LSA This is with 1.5 rockers
The Hot Cam is 218/228 .525/.525 112 LSA, listed with 1.6 rockers. So .525 lift would be .492 if it had 1.5 rockers instead.
I don't know for sure what stock LT1 springs will take, I would be worried. I'll tell you what I can do for you if you're interested. I have a set of springs that will handle your cam. They are not great springs but they are not terrible springs. They are internet racer supply's "terminator" valve springs. They were supposed to take a .550 lift. I ran them with my Hot Cam and 1.6 rockers with no troubles for 10k miles. I'm not using them back on my new heads.
So I've got some used springs that will handle the lift you need, they have retainers and seats. I don't I think I actually have the locks, but they are cheap enough. I'll sell them to you for $25 + shipping.
One thing you should be aware of, you do have to change the seats becasue they are double springs, as such you will need new valve seals. Factor another $15 tops for those.
Again I'm sorry that nobody foresaw your cam problems, but maybe I can help you out.
That won't work because he's already converted over to the newer opti drive and extended the drive pin on the cam. So he would have to put his old timing cover & timing set back on it to do that.

well, i think at this point i am just going to order the entire hot cam kit, i don't want to do all this twice, because i do want to add 1.6 RR in the future anyway...i'll have to settle for all that extra power!! :jester
taking the car apart again will be a piece of cake until i get to pulling off the intake, valve covers, etc...i am sure i will have plenty of questions for forum members!!! :)
how much are dues for club hot cam? :jester :jester
