Aftermarket Camshaft Options
I'm rebuilding my engine this summer, mainly with the goal of getting it back up to full running spec, but I'd also like to give it a little more grunt. My current thoughts are some aftermarket cams and possibly mild head work. However, this has lead me to wondering what the camshaft options are. I've searched, I swear! Here's my list so far:
ECUTune: 3 different profile sets listed. Web: No SVX listed on their website. Do they have stock profiles, or is every job a one-off? Delta: Same question. Are there any other options? And for those who have aftermarket cam experience, do you have any suggestions? If this thread generates some solid information I'll change this post to reflect the list that comes together.

Re: Aftermarket Camshaft Options
I had a crower cam ground for my Mazda a few years back. They didn't have anything listed, but someone told me about them and I was very happy with the results. If you're looking, they're at least worth a shot. Just call them up, ask for the cam shop, and tell them what you want.

Re: Aftermarket Camshaft Options
I know nothing about Web other than they are way expensive, although all the "best" EG33s use them so theyre prolly the best.
Delta will regrind your cams for 200 dollars per cam, do a search cause I dont have the exact numbers in my head but you can send them just your intake cams and have a pretty good improvement for 400 dollars. I'm debating doing that myself, but I'm so close to being done I can taste it haha |

Most places that do hardface cam welding charge about $25 per lobe, so you can see the costs add up quick! |

Intake Profile: .445"/ 11.3 mm valve lift 244° duration @ .050" 268° advertised duration Exhaust Profile: .460"/ 11.68 mm valve lift 244° duration @ .050" 268° advertised duration These are VERY fast opening cam profiles judging by the relationship between the advertised duration and the duration @ .050". These were certainly a one-off cam design for an EG33, based on the airflow the heads were making (which I faxed to Web). |

Re: Aftermarket Camshaft Options
My budget isn't terribly limited, within reason (I am still a full time student). $1000 is easily doable, probably up to $1500 if required.
Bob, That profile is meant to run with the modified valvetrain Jack's car has, correct? I would guess it's too aggressive to work with the factory valve gear? How is the "streetability" of that sort of arrangement? Chike had posted a set of intake cams he installed: Quote:

Re: Aftermarket Camshaft Options
Correct me if I'm wrong but I'm assuming the 3.3 RS has undergone a full conversion to Impreza valves and lifters or whatever. I think keeping most of the stock stuff (and your motor non interference) will limit how much you can modify your stock cams.

Re: Aftermarket Camshaft Options
That was my understanding as well. I think that profile will only work with the solid bucket conversion, which is out of my budget, ability, and need.

Re: Aftermarket Camshaft Options
Yup, you guys are both right. Those cams are of the solid tappet variety, and won't work within the limits of the stock valve springs and valve lengths either.

Re: Aftermarket Camshaft Options
Bob do you know what the lobe centers or valve timing is.

Re: Aftermarket Camshaft Options
I believe they're ground on the stock centerlines.

Re: Aftermarket Camshaft Options
Thinking the same as I'm gonna rest most of the power ups on my spare engien build on the head work. Don't know what I'll do for cams. Maybe even leave stock for now but now about the coverter to solid. How likely would a general shop motor shop beable to just go right ahead and do this without having to research or what not? Especially if I bring them to a shop that has worked with EJ's in the past. If i'm better off finding someone who's done it before who would be a good idea to bring/ship them to? Bob are you dirrectly an option on this? I just want to get teh heads built up and clean the block back up with new seals and such, maybe Cosmetic HG's and get it set to drop in.
