B2A Engine

[RubenF 0]

Hi Folks! So, im thinking about buying this XU engine that came out of a 405 , engine is a 1.6 XU engine but the code is B2A , i am thinking about buying this engine to be a future donator for my XU5JA D6B 1.6 engine. Are these engines the same in terms of block?

Not quite - slightly different pistons on B2A (crown/dish) .

The B2A is a XU52C engine, aside from pistons and cams it should be identical to a B6D "GTI" engine.

Sure! Pistons are quite diferent but the block itself, is it the same thing? But i will be using the same pistons that i have on my B6D. I heard somwhere around here that XU engines are pretty much the same, what changes is the pistons like you said, the crankshafts and the engine heads and camshafts. But the block itself without the sleeves, are they pretty much the same?

They will be close enough to use, some wont have the holes for the sliding tensioner of the earlier cars.

Yes !

 

Can even use "newer/later" ones from XU powered 306/406/Xantia/Partner 1.6/1.8 8v .. those are even better/stronger - more stiffening ribs on the block thus less likely to crack around the liner base or around the head bolt holes .

Scroll down and you'll see the difference ..

The XU5JP/XU7JP block doesn't have the same part number but it looks close enough, the XU7JB with it's swirl head is using a XU7JP4 block an is clearly not a good match.

Early XU5 blocks also lacks the oil pressure sensor bung despite having the "right" part number.

Interesting one .. did something similar on a GTI head along with the porting and valve seat mods .
