3100 cam choice.

[1995 Gold Ciera]

Okay. Got my Hooker muffler today (happy birthday to me). Gonna have it installed very soon. I may be moving fast here but I'm trying to get all of my ducks in a row so........

Any suggestions on cams? I was reading the section on regrinds and such but for me it would probably be easiest to just buy a new one. I'm gonna take a guess that the wildest I can go without having to have the car tuned is .206 int/.210 exh at .050" lift?

Thanks in advance for the help. I never would have to been able to go this far without you guys helping me out

you will want the car tuned regardless... so get something mild

Can any local mechanics shop do this or will I need to take it to a specialty shop?

if you are going to tune it anyway, why wouldn't you get something more wild? cost is the same.

It's a 95.. you'll have to upgrade to the OBD2 computer/harness to be able to tune it.. (or piggyback a Megasquirt or a OBD1 ecm)

I'd go with a wot-tech grind number 1617.. it's working very well in Redbird's 3400 with ported heads. It's making around 260 crank HP on stock manifolds. It's got a nice idle as well.

you'll need LS6 valve springs atleast.. stock pushrods will work with it.

Dave, what exactly is involved in a piggyback or Megasquirt. I saw Taylor swapped to an OBDII a bit ago in his Supreme and it looked like a bear to do.

Also, is it at all possible to run a mild cam in it without tuning it so to say?

I thought I could get the cam installed at tax season for under a grand but it seems to me it is gonna cost a considerable amount more right?

I do not recommend running without the proper lifter pre-load. I would run the stage 1 cam with the custom length pushrods.

If we go by cost, I can easily make the higher stage more expensive. That isn't how I do business and it isn't how you should judge your parts.

ohhhh so OBD 1.5. makes sense now. there should be enough room for a little more cam on a stock tune, but something that you can tune would be much better.

His car is OBDI !!!!!!

He has the A body which means he has the ODDBALL 3100 with the removeable PROM, and weird TB/MAF combo with NO MAP!!!

Tunercat has a def for him so he CAN tune it with stock stuff.

So in a way its a bit of a paint to swap to larger port stuff (aside from clearancing rockers) cause he has to get a separate OBD2 MAF and wire it in (not that big of a deal) but also he CAN tune his 3100 which is rare!

[SappySE107]

has anyone used tunercat to tune his setup? To scan?

$1FA 16196387 94 - 95 Buick / Olds L82, 3.1L, V6 27C256

I dunno if anyone has used it yet or not.

[1995 Gold Ciera]

I emailed tunercat about a week ago but I haven't heard anything back.


So I do have OBD1, huh? Well, I guess after all of these walls with this car, this may be a blessing.

[torq455]

whoa....95 and OBDII?! never heard of such a thing. talk about an odd duck! lol be interesting to see how all of this works out. well, pull your computer and see if you have a removable chip, then we'll know.

[Superdave]

I'd deffenetly be in for a copy of that bin file and tunercat def

he does have a removable chip. the A-body cars got the wierd style upper intake and didnt get the usual obd 1.5.

if you can take a pic of your engine 1995 Gold Ciera please do to show the different setup they gave it
