The Land Rover 4 cyl
2.25 litre engine was one of the most popular and
long lasting engines produced. This Land Rover engine
has a lot of potential locked away inside and there are several option
for upgrading the 4cyl engine performance.
For about the same price of a set of
tyres, you can fit the following to a regular 4 cyl engine and have
greatly improved performance and economy:
Performance Cam: Better top end and
torque, no loss in low end torque at all.
High Compression Cyl head : Increase
compression to around 9:1 without affecting reliability
Higher flow carb like Weber 34ICH, 36 DCD
or Zenith equivalent
The carbs are no longer available new - or very difficult to find. The
only carb options are a new Chinese or genuine Zenith carbs which work
very well but are not performance enhancing above the standard
Performance exhaust Manifold: Branched and
tuned exhaust manifold to replace the cast iron original
These old manifolds are no longer readily available. Consider a branch
manifold with a 4 - 2 - 1 design which
improves both mid range and high end torque
and power without reducing torque or power
at low revs. It is made of 2mm Mild steel
with 10mm flanges.
The manifold
replaces the standard cast iron manifold
eliminating that nasty constantly leaky
exhaust fitting.
Free-Flow pipe work and silencer : Help
the engine get rid of old exhaust gasses better. You will need the
services of the local exhaust shop to fit
the remainder of your exhaust system to the
branch manifold. It is, however recommended
that you have a full 63mm free-flow system
fitted at the same time to reap maximum
benefit.
Out of the above list the cam upgrade
gives the best performance increase, the higher compression head is
second in line.
The carb mod is
worth the extra money, especially if the existing carb is a
Solex.
