Ive just gat my hands on one of these engines,over and above 6 manifolds and a pair of cams what else can I do (Basic stuff/mods) to wring more power out of it ?,If I fit RS cams would it be worth getting them ground first ? (Live close to Kent + Piper cams)

:D

dug out some info I remember seeing in the Haynes manual, the earlier 3 bolt camshaft pulleys used on the R, RS and 7JP4 are marked on the rear of the hub with a single digit.

J4R has the inlet numbered 3, the exhaust numbered 4, the RS engine uses 2x No4's.

the 7JP4 engine is numbered 1 on the inlet, 2 on the exhaust.

the pulley itself is the same, though I'm unsure if the same numbering exists on the later single bolt pulleys, they do all share the same arrangement again.

I have somehow only just noticed this thread! I have an xu10j4r engine that has now been running since xmas eve in the 205. I picked it up for 140 including the gearbox. It seems very quick, and a great improvement over the 1.9 even though it is rated as only 5bhp more. I also have an rs head I picked up for 30 that I was planning on swapping in. I haven't quite decided if I am going to swap the whole head or just the cams yet. (as swapping the head requires more work). after that there is just the manifolds and ecu to do.

for anyone thinking of using the xu10j4r one less thing to worry about is that the exhaust manifold doesn't reed re-angling as it just bolts on!

doesn't the r have a lower compression ratio too?

All the NA XU10 petrol cranks are identical. I'm unsure if R and RS blocks have oil squirters.

I wouldn't put old pistons in different old bores, but in principal yes.

Thank you, yes I Know, but we have new parts for xu10j4 engine in Iran and I want buy an stoke GTI-6 engine for my peugeot 205, and I want to know if my engine had any problem can I fix it or not. But apparently I can handle it.
