Solid Lifter Camshafts
I currently run the Cosworth M2 Mivec cams with upgraded valvesprings & stock hydrallic lifters.
I am interested in upgrading to a set of higher profile solid lifter cams.
Besides the solid type cams & a set of solid lifters, what other components do I need to get? And can I retain my current valvesprings?
The cylinder head gotta be removed to change the lifters & cams or I can do it by opening up the cam cover. Do I need a new head gasket as well?
All advices appreciated.
Thanx in advance
Victor

i cant answer all your questions but i can tell you that you do not have to remove you head for any of that ... just the valve cover and cams have to come out....

Been doing some readings on the BLE solid lifters & they seen to be not so advisable & not necessary unless I wanna do above 10000rpm on the dragstrip.... ....
Hmm... ....

ah the solid lifter question.. i love them. just make sure your ready for them or need them. 8k plus RPMs and peak power is where you will see gains over hydraulic cams.
Solid lifters will require setup. do not get the BLE screw type lifter. You should either get the tomei lifters or the BLE Solid machineable lifters (these require more setup)
You will need to run a solid lifter profile camshaft. the opening and closing rates will be slower and softer than a hydraulic profile. Hydraulic profiles on solid lifters will make all kinds of noise.
Finally depending on your springs and the cam you choose will determine whether you can keep the one's you have or upgrade.

The primary issues I see with solid lifters are the aggravation vs. performance benefit. They need to be adjusted from time to time, and they generate additional noise that may prematurely trigger the knock sensor.
When one considers that there are racers here who generate far more power with HLA valvetrains than any street car in this forum, it's hard to justify switching to solid lifters. I take Greg's opinion with consideration, but I have yet to see something that indicates that the advantages outweigh the disadvantages, especially for a street driven car.

Greg, wat kind of improvements should I be expecting if I switch from my current Cosworth M2 Mivec cams to the GSC S3 280 Mivec cams?
Pls advise me through PM on the S3 280 price, stock status & if possible freight charges to me in Singapore. My postal code is 543273.
Thanx
