Series I (SC) Cams

its my understanding that comp cams will do just about anything. just call them with your questions and they will steer you in the direction that best suits your finances and power expectations. when i had my acura legend with a v6, in 04,they had one for around $400 bucks. i would think that the s1 3800 would be available too. let us know what you come up with,and how many additional hp you get and all the periphieral info that must go with... bigger injectors ,higher airflow,fatter tires bigger exhaust tubes, fuel pressure riser, reprogramed ecu,and just go ahead and kill the cat while youre there,and who needs a resonator anyway?..last but not least the tall beautiful red head in the passenger seat(that we did all the work for anyway) who loves to sit on all that rumble!

zzp has series 1 roller rockers in 1.8 ratio. you could go that route instead of a cam. (you shouldnt need power in the low end anyways)

Okay with a little bit of digging and help from bonneville club I seem to have stumbled upon a website that sells cams. The webiste is called crowcams.com.au The holden one makes cams but im not sure how our series 1 is converted in austrailia like thier ecotech or something. I believe that our s1 is their sII. You guys hopefully know a little more about this than me. I know seriesoneperformance used to make them but as all you know we cant find them anymore for whatever reason. I would be interested in camming mine to sound like the cammed gtp's on youtube and it would help out our top end a lot as well.

Thanks guys
Shawn

compcams still has em...

could you post a link to them please.

go to compcams and look up your car. im in the middle of something..

for Australian, our series 1 is their two, and our two is their ecotec...

Looking for an aftermarket cam for my Series I swapped Fiero but can seem to find any for the Series I, only Series II. (and yes I know the Series II is better and more aftermarket support). I already have a pulley swap, injectors, custom self-tune (Megasquirt stand-alone ECU) but looking for a little more.

As far as I know there isn't 1 available. Karma has about the best knowledge of the S1 on this forum and he has never mentioned them. We have explored basically every other available options for the S1. Maybe Methanol injection (if you have no teflon coating on your SC rotors) since you've already tuned your PCM. If it's still a factory SC it will be coated, if it's a Reman they strip the coating as part of the process, making it a good unit for meth injection. If you haven't already done so, try to get your hands on some Yella Terra 1.8:1 Roller rockers they will give you a good boost on the top end. Sorry I couldn't help you on th cam hope these other ideas help.

Im still running a factory M62 but I think its from a '93 which I believe doesnt have the coating. I know about the rocker arms but I was trying to find cam instead. I am currently running this set-up on the stock Fiero V6 exhaust (minus cat) and I am planning on doing a 2.25 stailnless cutout. I also know that the N/A engines had the roller rockers ad the SC'd ones had the regular, but I swapped the heads from the N/A to get the rollers and self ported the TB. There are no known stack intercoolers avalible, I have since been looking into welding the intake manifold to SC coolant passages closed and have fittings put in the SC housing to run cool water through the SC and TB seperate from the motor, but thats down the line.

Sounds like you've thought this out pretty well, but yeah unfortunately there were no cams available when I went looking awhile back so i went with the RR's. Not sure what the ratio of the rockers would be on a stock N/A as opposed to the 1.8's from YT? But I'm sure they are an improvement over the stock SC'd ones. Good hunting on the camshaft and if you find some please let me know.

These guys will make you a series one cam to spec:

Or you can get one of their pre-made ones, though they are more optimized for NA.

(to give you an idea of prices.)


They have made many series one cams for both turbo and supercharged applications and will probably know exactly what you need if you let them know you have a North American series one engine.
Keep in mind that our series one is their series 2, and our series 2 is their Ecotec.


... and you should pick up a 94-95 m62. (i think Derek on this site has one for sale). The inlet and TB is MUCH bigger than the 93 one. NO amount of porting the 93 can come close to the 94-95 which is stock half way between the stock series 2 and a northstar TB. Also the efficiencies of the newer one let it run the 2.85" pulley instead of a 2.55" to make the same boost as the older one.

I may be worng on this but I thought I read that we have the same block design as the older turbo buick v6's? If so Comp Cams makes cams for it and if not they will make custom cams. They would probably need a stock camshaft and the specs you want it built to and I'm sure it wouldn't be cheap but... Its an option to look into.

no. The turbo 6 of the '80s was based on the old 231 V6. The FWD 3.8 was the Series I 3800 where everything went metric. Nothing is the same.

Damn that would have been too easy. Well I know Comp Cams USED to make custom cams about 10 years ago but I don't know whether they still do. A custom made cam from one of the big cam companies (crower, comp cams ect) might be the only solution. There's a slim possibility that once they have a stock series 1 riv cam in their database they will begin to offer it permanently. Not likely but possible. If a couple other series 1 guys step forward at the same time it may increase the chances or at least decrease the cost. Maybe lol

These cams WILL work on your engine.

They can make a custom grind or use one of their stock ones.

The Holden market in Australia is what initially drove all 3800 performance development here in the west.

Comp Cams USED to make SI cams, but they do not anymore. Sometimes you find it in online catalogs, only because they are out of date.
