Here are our camshafts from Cat Cams for BMW M3 E36 engine code S50B32
Description :
The Cat Cams camshaft will allow you to considerably increase the performance of your vehicle.
When a vehicle must receive extensive mechanical preparation to obtain results worthy of the name and above all a significant range of progression, work on the camshafts becomes inevitable.
When preparing the Cat Cams camshaft, two modifications are observed: the valve lift and the opening angle.
Valve lift allows you to change the length and opening angle, which causes less or more air to enter the combustion chamber.
You should know that more air entering therefore modifies the air/fuel mixture in the cylinders, which increases power at high revs.
Also, the greater the opening angle of the valve, the more the air flow increases, which promotes the air/fuel mixture and therefore more power.
Therefore for use in competition, leisure, circuit and other, the revs will be sharper, the character of your engine will be more furious and thus you will benefit from a better range of use which will become a real asset.
Without broaching the subject of driving pleasure which will increase your sensations tenfold.

Camshaft profile available for BMW M3 E36 engine code S50B32
Sports profile :
-
Cat Cams camshaft reference: 1303614/S / Opening 0.1mm, intake 278°, exhaust 270° / Opening 1.0mm, intake 250°, exhaust 242° / Max lift intake 12.50mm, exhaust 12mm / Lift at TDC intake 0.90 mm, exhaust 2.15mm / Full inlet opening 129-69°, exhaust 114-76° / Inlet clearance, 0.30mm, exhaust 0.30mm. Mechanical pushers.
Camshafts for use with VVT on intake and exhaust (like original). The VANOS (VVT) system on the intake camshaft changes the PD from 129° to 69°. Data is displayed for full intake delay (VVT disengaged). The VANOS system (VVT) on the exhaust camshaft changes the PD from 114° to 76°. Data is displayed for full exhaust advance (VVT disengaged). Verify that the distance between the valves and piston is at least 1mm with the VVT engaged. Improper installation will result in serious engine damage! VVT reprogramming, operating range adjustment or even elimination of the VVT system should be considered for camshafts with increased service life. ONLY for track applications and professional street use with engine management or adjustable carburetors.

VVT reprogramming, operating range adjustment or even elimination of the VVT system should be considered for camshafts with increased service life. These profiles require racing cam followers with a shim between the cam follower and the valve (shim under the follower). It is not possible to use these profiles on std cam followers with the shim between the follower and the cam (shim over follower). FOR COMPETITION REQUESTS ONLY. The following details should be checked: - The camshafts should turn smoothly in the cylinder head, ensuring free stroke by machining where necessary - The distance between the valve seal and the retainer at full lift should be d 'at least 0.6 mm - A minimum valve spring travel of 1.0 mm at full lift must be provided - distance between valve and piston 1.0 mm (preferably 1.5 mm). check 5-15° before TDC on the exhaust, and after TDC on the intake - valve clearances should be adjusted using mechanical caps - please ensure that the lash cap does not touch the valve locks ! For use ONLY in competition engines with independent engine management (throttle position sensor) or carburettors.
