yes i have the 1g , yes rare, underpowered i really dont thnk so , sorta laggy but im going to do a single conversion with the Hks manifold, there easy to find. other than that , its like a mix of a 7m and a 1jz.very similar looking motor between those 2, i traded the Silvia for it . and havnt had any regrets bout that, all i do is change the oil >lol
