Its wayyyy to low at the moment bumps and rubs all over and is super soft, needs at least twice the spring rate especialy in the rear,

Will start the search on Ozdat,

you probably will have to raise it for circut racing but as a tidy street car looks good, you can search ozdat.com for heaps of useful l series info too.

This looks like what we always refer to as a Stanza, but we had them stock with l16 not l18.

Yeah i second that unless its scrubbing or bottoming out which can be fixed as you would know without raising it Leave it as is. It looks really tidy and has a nice stance.

Don't know about the L18 (I'm learning about em these days too) but I do think that the car looks great right now...please don't raise it. :)

After a guy I work with came to watch the racing on Saturday his heart got set on the good old datto's... today he purchased a MINT condition 1979 Datto 1800J SSS which I think was fairly unique to SA as I dont pick up much by google,,,

Has a semi tired L18 in it with the twin SU's, motor runs like a clock but has some blowby after her 180 000km's.

I am gong to help him spice it up a touch to get her to perform nice in Marque class so I have a right hand man to help me fend off the Alfa's but I have never paid any attention at all the the L series motor so here I am asking for some help...

Nothing crazy needed, but I will change pistons and obviously do head work while I do the motor, anyone know of some slightly higher comp pistons the swap in easy? also what is a good size cam if one keeps the SU's (they work 100% so it would be a bit sad to loose them).

Last of all, what sort of power gains do the L18's make with a nice exhaust manifold, exhaust, cam, head work, bump in comp etc?

And yes the first thing we do will be to put new springs in and raize it a bit!
