Title: Pistons
Post by: bentparts on November 09, 2012, 06:16:57 PM
I saw a thread about 10.5 to 1 pistons for the 8V 1.6 in the regular Suzuki forum and it got me thinking ( I know, dangerous  :laugh: ) Can a 1.6 16V be over bored enough to fit the 1.8 pistons? does anybody know how they get the displacement increase? Stroke and bore ? or just bigger bore? A 1.8 with high comp pistons and a good head job, header and proper fueling may be a better all around engine that a turbo'd one. Better bottom end for sure. Just thinking out loud.

Ahhh - you do realise that the two engines have significant differences and in fact belong to two different families - the 1.6 is the G series, and the 1.8 is a J series - the J series are quite a bit larger.

The 1.6 bore is 74.9mm (2.95in), the 1.8 bore is 83.9mm (3.31in) - so quite a bit larger and no, I don't think they'll fit.

It is possible to shoehorn a J series engine in, and if you want to go that route, consider a J20, they are physically the same size and there are more of them around.

Thanks Fordem, no plans to do an engine swap, just have this long block layin around begging for some attention. I just can't leave things alone  :laugh: Appreciate the info though!

The cylinder bore centerlines of the Jengines are significantly larger than the G series engines, physically a taller and longer engine. The pistons wil not work regardless of how they could be modified.

But 16v dohc swift pistons can be canabilized for use with a 16v sohc head per what I have read on TeamSwift.net

Kinda a moot point anyway since Ecoast is gonna be getting my old engine now.

If anyone is considering the j20 engine, they might as well step up to the j23.  I have read that it will work fine, in place of the j20.

I'm just guessing here but do the 20 and 23 refer to size as in CC ? Still a four cylinder correct?  I like the idea of more displacement but still in a small ( inline 4 ) package. A mildly boosted engine that size could easily support 200+ hp and have decent torque to boot.  Should still be fairly economic too.  Hmmmmmm

J20=2.0L
J23=2.3L
Both are inline 4 cylinders.

You will need the oil pan and pick-up tube from a Tracker/Vitara if you go with the 2.3 or 2.0 from a Aerio though.

Thanks Drone. I'm not going to do anything soon, just run the turbo engine for another 100000 + miles I hope  ;D. I'm just playin around with ideas for now. Isn't the Aerio a FWD with transverse mounted engine?

Yea, but it will fit fine since they have the same block.  You will also need a different water outlet unless you punch a hole in your firewall.
