Ca18? Running Like Buttcrack

[nastykoga]

hi guy

im new to these forums. I got an R31 pintara and its needs a good kick in the butt.

I got the car a few years ago. when i bought it, the guy changed the engine after he blew the CA20 and put a CA18 SOHC in. Iv been hunting around the net trying to find any info on the engine, but im having a bad time find anything of value.

anyway she chugs and carrys on and vibrates like no tomorrow even when warm. the only remidy i found was to increase the revs with the throtle cable, but it has to rev very high for it to be stable which makes the exaust smell like fuel. i figured it had to do with the timing but even then it still ran bad(unless i did it wrong). the only time she goes good is when im driving 80ks or above, is there any ajustments i could make or something i can check for it stop doing this. which is the reason im looking for a manual, though all the manuals i find are for the CA18DE/T.

any help would be muchly appreciated.

also i blew my flange gaskets around the cat. when i replaced them i had a look at the cat and its hollow and i know thats not normal.
