Thread: More from a S2A 4-cylinder?

Make sure that Distributor etc are all timed/working correctly.

This should give you a very sharp 2 1/4 petrol motor that will perform very well.

Very interesting Chris.

Can you just clarify the timing? Do you mean set advanced 3 degrees from the normal setting for the standard cam? Or just 3 degrees before TDC?

cheers

Diesel cam is advanced 3 degrees from the normal setting. I have had to do with engines set up as mentioned and they have been very sucessfull - and use all standard Landrover parts

Christopher

PS One of my sons has just informed me that the 2.5 petrols use the camshaft that I have suggested

What do you intend to do with the vehicle? do you want the extra power for offroad work or for extra speed, as they are two different specs, My 2 1/4 litre 2a has Extractors, a 2" (50mm) exhaust system with a free flow muffler,still runs the military 8 bladed fan and full shrouding & oil bath filter, bellows like a bull and cruises at about 90/95 kph it also has a Webber 34ICH carby, but will be going back to the Zenith 36IV unit, the float bowl of the Webber is a little small and it will vapourise after a short 5/10min stop, and will give fuel starvation problems 100metres after restart, speed will be limited by the gearing, the series Landrover is fitted with 4.7 ratio diffs, so, the engine reaches peak revvs before the vehicle reaches peak speed, 5,300-5,550 rpm is when the engine self-destructs this particular motor has done in excess of 100,000 miles the cam is standard, point type dist, light head shave, .040 thou O/size (bore wear) if you are in doubt just ask Numpty's Missus as to how it travels

cheers

Hi Uncle Ho

I'm looking around for a 2A to restore for weekend road use and occasional beach work. (It won't be boulder-jumping or mud-plugging.)
My preference is to get a SWB, but these appear to be much more scarce than LWB's. I'd be happy with either a soft top or a hard top, as I intend to ultimately acquire 2 tops that I can swap as I choose. (I don't want a 5-dr s/wagon.)

If I have to settle for a LWB, then obviously a petrol 4 will be working harder than with a SWB. Hence my interest in this thread. It seems that a 4 in good nick, and with the changes proposed will be quite OK. (From what I've read, it seems that the 4 is more reliable than a retro-fitted S3 petrol 6.)

Further down the track, I want to fit a S3 all-synchro box and also an overdrive, to make it better on the road. It may be a hybrid, but I want a LR hybrid!

Just trying to do a bit of forward planning! :-)

cheers

Doug

Doug - There are plenty of SWBs around if you look. In fact my father (in Brisbane) has one with all the steel bits galvanised which he may be tempted to part with.

The SIII box is a retrograde step IMHO. Weaker in many places. A IIA box is just as easy/nice to drive once you get some practice at double clutching.

I have heard of the mods CHT mentioned above, apparently works well. In addition, you could fit a diesel flywheel, they are 5-10kg heavier, so would give you more torque, at the expense of a slight decrease in acceleration.

That's interesting. I'm not after acceleration, so that'd be good. (Ta.)

Yes pls. Can you PM me with the contact details.

cheers

Just taken the fan off olmate and replaced the std air filter with a paper cartridge. Will see how she goes. I do have a thermo fan fitted so I expect all things to be good.

Will take her for a drive tomorrow and sus her out.
