I purchased them through
Import Performance Parts - Import Performance Engine & Racing Parts. They should have the price posted.

and yes, the lift is massive on the cams. The duration isn't as much as the 101 cams but the lift is greater. We're not looking for a huge redline so I didn't want to go too crazy on duration.
I still have a lot of work left to do with the car before I start trying to pull great numbers. Primarily the fact that I have been too busy to play with it as of late and it still needs a FPR and new injectors.
Some additional info on what was done with the head (post-marco purchase). - ARP 3sgte head studs, with the cam-gear bolts cut down to fit the 5s
- 33.5mm intake valves
- multi-angle valve job
- cleaned up the porting
- milled down and lapped
- shimless bucket conversion
- Crower custom 55/165 lb valve springs
another thing you guys may enjoy hearing. none of this work is inside of an mr2 nor a celica body. yes, that's right, it's a camry (gen3).  |
Good stuff. It's nice to see someone else doing a more aggressive 5sfe setup. You should see a nice kick of torque at about 4500rpms from that intake cam and then that exhaust cam will help open it up a lot in the 5500-6500rpm range. You should consider doing the bottom end work to spin it past 6300rpms if you haven't already because those cams will be able to use it. And of course bigger injectors and tuning.
Which shimless buckets are you using? That is one thing that I have considered but never done. With that much lift though I think it is a wise choice.
