Nice job Atchi!

Just out of curiosity why not start with the G16 closed deck block?

Hi,

I just want to keep 1300cc.
Just imagin people's face when you tell them it is 1300cc. They will be pi**ed off if you over take then in a track day.
My mate has done this with his Swift Gti and past Ferrari and Aerial Atoms!

Beside, G13B crank is stronger and I don't have G16 engine. I got 4 G13B engine spares as well!

Cheers
Atchi

you can get rods from suzukird custom rods are not too expensive these days and a honda d16 crank can be used but its alot of work involved

What do you mean no good?
Gti pistons are 0.95mm longer from the centre of the pin, so it will work. So it will gives better CR than 7.2:1 as we have worked out.

Anyway, here is a finished block!


As you can see, there is no gaps between a block guard & block itself!

why would you use g16 rods in a g13 engine...did you miss read the question atchi ?

I'm using G13B after market rods... never G16 rods as it won't fit G13B.
What I mean by 0.95mm length difference is that the piston height is different.
G16B pistons has 0.95mm shorter/lower from the centre of the piston pin to the top. As a result, G16 16v Vitara pistons will give you extra 4.4cc to give you lower CR.

So, I have 1mm shaved block as well as 1mm skim from my cylinder head. This will give me better CR than 8.2:1, I shall check what CR is by compression test to how good it is. 10:1 is about 200psi when it is healthy. I assume my engine will be healthy after running in... I hope this will be a good guess to work out my new engine.

Cheers
Atchi
