OK - block, cam and head go in for machining on monday, i'm getting excited.
Would you recommend any particular oil for breaking in? I was told by my car club to use a standard oil along with a zinc additive like ZDDP in the initial oil fill.
OK, so my concerns are as follows - Impco wrote their reference guide 30-ish years ago when most blocks were cast iron lugs running leaded fuel. Compared to this, my motor was an advanced unit for 1990 - all alloy, Japanese build quality, and designed from the get go to run unleaded petrol, so...
Engine Specs as far as I know them
G16A (8 valve SOHC), 4 cylinder, circa 1992.
Bore 75.0mm (2.95 in)
Stroke 90.0mm (3.54 in)
Piston Displacment 1590cm (1590cc, 97.0 cu.in)
Compression ratio 8.9 : 1
I just realised I got the compression wrong... I thought it was 9.5:1... turns out that's the...
Thanks for all the great replies... I am a bit more confident in the project than I was this time yesterday. I'll have to find some of that Bon Ami stuff, i've never seen it here in Australia.
A couple more quick Q's - chrome rings vs cast iron rings... how much faster will cast iron rings...
I believe with the machining involved the compression ratio will automatically raise from 9.5 to 9.8:1... but that's just the maths i've done. I will investigate what pistons can give me an even higher CR.
My main concern is my want to use chrome piston rings for longevity, but in regards to my...
Please forgive me if this is an unchallenging question, but i'm an electrical engineer looking to give my automotive pride and joy a new berth of life!
I have converted my Suzuki Sierra (known as a Samurai in other parts of the world) to run straight LPG and all has been running swimmingly for...
