is there a differance between a series 1 and 2 engine, the reason i asked is the original engine in my series 2 went bang and i installed an engine i had spare from when i had my xr3i (bought, was gonna drop it into the 3i but lost interest and bought a real rs.) i decided to fit a new cambelt and water pump but the water pump on my original engine is totally differant to the one on the spare. the original wter pump has one outlet and the spare one has 2 will post puics tonight to make description easier. any help appreciated

cheeRS toby

 

i forgot to also mention that im really close to giving up with this car its given me so much grief so a few kind words of encouragement would also be appreciated

 

the only thing i no is the oil filters are diff, s1 has a massive old filter on and s2 has a long thin 1 on efl 600!

not sure about water pumps though

 

cheers dude, will take the old pump to where i got the new one tommorow cant be bothered today.

 

lol, you need any other bits im breaking mine!

 

basic engine is the same apart from the s1 cam and valves are better, ancillary wise water pumps have different outlets so u will need to swap the pump over , s1 inlet manifold is a 2 peice job not one piece like the s2 so basicly just use the bare engine with all your s2 ancillarys and you will have no probs

flywheel and clutch are bigger on the s2 so use those

 

2 outlet water pump is s1 item

 

water pump is diff like said,also the flywheel is diff to so much sure ya change it!S2 220mm clutch s1 only had a 200mm one

 

also the oil pump fittings are differant too make sure you order the right one if your gonna rebuild it

 

More or less every part is different in some way, but none of the changes make one better nor difficult to replace with the other.

 

cheers for the help people, yeah i noticed that the flywheel and clutch were smaller but swapped em over any, clutch on the s1 engine looked burned and the s2 clutch was like brand new the one problem ive got with the water pump is the mounting holes are different, will have another good look tonight.

 

they shouldnt be different,ive done the swap a few times,also the alternator hanger is diff,but i guess u knew tht

 

yeah i know about the alternator. nah your right there not different was just me being a nobhead and not looking properly. might fit it all tonight, bit too fragile at the moment
