Same engine blocks?

Hai,

Does anyone know if the lanos 1.6 16V block is the same as a 1.5 16v block from a nexia/racer?

might have a leak in head gasket so in need to take top of anyways and tranny's 2nd gear syncro is busted so i have to take that off also...

so i wanted to drill a 1.5 16v block to a 1.8v block (think this is done on espero stock already) and use the 1.8 pistons in my lanos on the stock 1.6 16v head (heard this can be done)

not that much work considering head/tranny is out of car then already anyways (maybe i will even buy a 1.8 espero engine so pistons/crankshaft allready are in there IF my 1.6 lanos head will fit?

So either block needs to be same... OR my head needs to fit on a 1.8 8V engine from nexia/espero

Anyone know?

Here is a site with some specs for the A15SMS (8V SOHC) and A15DMS (16V DOHC)

http://www.usedautokorea.com/epublic/pr ... rp=1&cid=3

So the bore and stroke are 76.5 X 81.5 for the 1.5L

The bore and stroke for the 1.6L is 79 X 81.5

So I would think that you could probably put the 1.6L head onto the 1.5L block

Yes the A15 and A16 both 16v or 8v share the same block "small block"...

As Erfinder said...the main thing is the Bore.

The Espero 1.8 shares the same block as the 2.0 "big block" family.

Unfortunally you cant use the 1.5/1.6 16v head on a big block engine...

hmm crap...

But if i bore a 1.6 blok to 1.8 i can still use the head normaly no?

but then the main thing is to figure out if i can fit some 1.8 pistons on the 1.6 rods... being from same family (GM) i should be able to i geus if the (round bar that connects piston to rods dno name) is the same size... ofcourse the lenght isnt the same but the thikness could be?

The 1.6L is a bored out 1.5L so I'm not sure how much extra boring you can do.

You might be better off getting a custom crankshaft or see if there is another Holden engine that has a compatible cranks with a larger stroke.

Hmmm.... the 1.8L has a 81.6mm bore and 86mm stroke... definitly the same block as the 2.0L with a smaller bore.

hmm crap... well the thing is i need to have the engine get more power but it must still look orignal (for crap yearcheckup and laws over here)
i aint supposed to do any of this but was thinking if i bored it and used other pistons its not like anyone can notice whitout opening the engine anyways

well i talked to a revision shop... they said it is alwasy possible to get my 1.6 to 1.8 using stock block... but he needs to try to c if i need loose cilinders to support block strenght or not.

SO once i got me a 2nd block im gonna try this out

If you check out this German performance site they list both a 1.6L small block and a 1.6L big block as well as a 1.8L small block and a 1.8L big block.

http://www.imotecgmbh.de/Leistungsteile ... -opel.html

The parts listing shows:

SMALLBLOCK :
8 Valve --> 1.2L
8 Valve --> 1.3L, 1.4L, 1.6L
16 Valve --> 1.2L to 1.6L
16 Valve --> 1.8L

BIGBLOCK :
8 Valve --> 1.6L to 2.0L
16 Valve -->1.8L ECOTEC
16 Valve -->2.0L
16 Valve -->2.0L OPC
16 Valve -->2.0L XE
16 Valve -->2.2L ECOTEC

So the question is which block the Daewoo A16DMS is.... it could be a big block or a small block ( since both are made by Opel )

I'm guessing it's a small block since they don't list a 1.6L DOHC (16Valve) bigblock engine....only a Bigblock 1.6L 8V.

If both the 1.6L and 1.8L you are looking at share one block design ( big or small) you should be able to interchange parts

well i could go and try to fit the headgasket on the 1.8 block... if the cooling/oil holes are same i can still yust change block... if not then im gonna look for a 1.6 to bore out

or use the 1.5 i have in a wreck atm (as im told 1.5 is same)

Erfinder,

is strange but i've never seen the 1.8 small block...

there is a 1.8 16v (X18XE) but is BIG block... the head is the same has the X20XE (ECOTEC).

the A16 block is small block... i've tried once to use a 1.6 16v head on my old 2.0 8v... and guess what does not match...
