Perkins?

All i know about the engine in my new landy is that it's a '4L Perkins Engine' - it's also pretty loud, and not very fast!

I'm keen for an ID on this engine if anybody can help? also i'd like to make my landy go slightly faster than 50mph, or at least, 50mph with less noise!
Short of an engine swap, i've heard replacing the Diffs with ones from a discovery can help. Is this advisable? easy job? what kind of cost? or should i really be looking to swap the engine? I'm not planning on pulling trailers or particularly heavy loads so don't /NEED/ the power of this engine! although i do like its simplicity and apparent reliability!

Thanks in advance!..

Its a perkins 4203 unit and is intended for tractors, Massey Ferguson to be precise.

Power is a rather mean 63hp so it'll never be fast

I don't think it is a 4/203, they have vertical injectors. And they were used in many different applications, not just tractors. Fork lifts, Commer Vans, Boats, all sorts.

The subject is being covered in another thread, for some reason, OP posted about it twice.

No worries. Perkins engines are a big subject, I am not even certain myself, so I have called up freelance for another opinion

Sorry! i'd intended for the other thread to be for the electrical and this to be for ID - other forums i'm on are pretty picky about this kinda thing! i'll merge future similar posts now i know!

It doesn't matter, but it saves on having loads of bitty threads about the same vehicle. We can see all the posts on LZ Live anyway.

Does look like a 4.248 but the inlet manifold doesn't look right to me, only had an NA one tho so could well be different. Also the oil cap (at least on tractors) was down the side by the IP rather than on top

The 4/248 in my Massey had vertical injectors as well. But it may be that later ones had the injectors angled, not sure.
It is the turbocharger that made me think Prima in the first place, most of the bigger engines were naturally aspirated, and mostly sold in the cast iron sump agricultural or stationary engine variants.
