– MED Engineering Ltd MED ST2 CAMSHAFT KIT

Description

All MED camshafts are machined from cross-drilled steel blanks, never re-profiled, so you can be assured of the highest quality product. The three profiles have been developed specifically for road use with over 35 years of A-Series experience.

The Stage 2 kit comes with the following components;

Cross-drilled billet camshaft
Chilled iron cam follower set
Camshaft lock tab
Steel-backed oil pump
Camshaft timing disc
Double valve springs
Steel/alloy vernier duplex

Camshaft profile choice;

MED HT - An excellent road camshaft, 256/256 duration with a power band from 1000-6000rpm
MED RS - Our Road Sport camshaft, 270/284 duration with a power band from 1250-6500rpm
MED XT - Our track day camshaft, 280/280 duration with a power band from 2500-7250rpm
MED T3 - Special forced induction camshaft, 264/276 duration with reduced overlap

Additional Information

Which camshaft should I choose?
It's entirely dependant on your driving preferences and the spec of the other engine components. Road trip mile muncher or daily driver? The most civilised HT profile would be ideal. Fast road car for country lane blasts? RS makes a good compromise. Fast road/trackday/rally car for the weekend? Go for the XT. A more conservative camshaft spec can often result in a more enjoyable driving experience on the road, as the power band is lower in the RPM range.

How much power can I expect?
It's impossible to answer without knowing the exact spec of the engine and the quality of the rebuild. However, for a rough guide, if we were to take an identical 1380cc high performance road engine with a modified head, re-worked crankshaft, single HIFF44 carburettor and 1.5:1 roller rockers, the following peak outouts could be expected:
HT - 100lb.ft/100bhp
RS - 100lb.ft/106bhp
XT - 100lb.ft/112bhp

Which engines will this fit?
All BMC A-Series and A-plus engines, with the exception of eight-port head conversions and late Rover MPi Minis (1996-2000). Standard 850 engines do not use camshaft bearings, so you will need to line-bore the block and fit bearings. 998/1098 will require a different oil pump to that provided in the kit, so please contact us for more help, as we can supply a different type.

Can I change my camshaft in situ?
It has been done, but we wouldn't recommend it.

Do I need to fit 1.5:1 rockers?
Our camshaft profiles have all been optimised to work below 1.5:1 rockers, but it's not essential. We also supply 1.3:1 ratio rockers to cater for personal preferences and all engine builders have their own tastes. Upgrade to the Stage 3 camshaft kit to include MED 1.5:1 roller-tip rockers.
