Ive got a g16a 8v pulled down and ready to go to the machinist for a hone potential bore [tide marks left in the bores from sitting so long]. Also will have it checked for all the usual stress points. If it comes back a useable block what would you guys do as far making it as durable/reliable as possible.
I hope to use Aisin 3k carb set up thats on my g13 atm, benT's oil pick up bush an his adapter kit but would love to hear from you guys what parts youd use or weak points in the factory build I can fix now. Thanks in advance.

Nothing much goes wrong with G16as as long as they aren't overheated. Check for cracks in the block around the main bearings, I can't say I've heard of it happening to G16as but it certainly does happen to G16b. Some G16s have a main bearing girdle, it certainly wouldn't hurt to fit one of those if yours doesn't have it.

The G13 oil pickup I had was a much smaller diameter than G16 so I cut/welded the oil pickup instead of using the bush. Later G13s have a larger diameter oil pickup but still not of large as G16. I figured suzuki made it larger for a reason.

My G16a had oil pressure problems caused my a worn oil pump. Yours may well be fine but new Aisin oil pumps are pretty cheap. When I was looking a few years ago they were much cheaper from USA than locally. It's pretty nice glancing at the oil pressure gauge and seeing 60psi at cruise when it was doing sub 20psi before...

G16a takes a different fuel pump to G13 and it's kinda pricey, I made a block off plate and converted to electric.

My G16a Sierra has an ebay 4k carby. Out of the box it was extremely rich (sub 9:1 afrs) and it took a lot of tuning to get right. Now it gets as good as 9.0l/100 and even working hard in the dunes it gets 12.xx/100. You may want to fit a wideband oxygen sensor to make sure you aren't running to rich and washing down the bores on your fresh engine.

I bought a new timing cover and isolators which were cheap from Megazip. The timing covers are always warped/cracked/chewed up and they love to rub the pulleys/belts.

I had a pretty good look over it making sure there were no visible cracks between the usual areas but will have it tested professionally.

Duly noted I will look into that further.

Gonna be replacing everything bolt on with hopefully OEM stuff but appreciate the heads up.

Thats a great suggestion, thats exactly the real world applied stuff that helps.

The one i pulled off had been eaten almost entirely thru at the bottom from wobbling into the pulley. Thanks alot mate given me a bit more to think about.
