If the later 5S cams are identical to the late model 3S cams, I'm unaware. I just went with what the shop had available and what worked. Based on the '91 cams being smaller, they ground too low. When we used the late model 3S cams, there was more meat and thusly we achieved nearly a stock base circle. No complaints nor curiosities on my part after that.
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).
