4G64 questions

[jaxon23]

i am looking into building a 4G64 like what is in my spyder but with better internals to run atleast a 100 shot of nitrous. i see 4G64 engines for 1G's but is this the same block as mine?i am just looking around in junkyards and stuff but didn't know if i needed to look just for spyder GS's or do i just ask for a 4G64 block and go from there? i have heard my engine referred to as a 7 bolt and a 1G as a 7 bolt as well...is this correct and i am guessing the 1G is a 4G63 and not a 4

Do you have two cars or is this just a replacement for the spyder? The 4G64 didn't come in the 1Gs, in the Eclipses they only came in the spyder. The 4G63 went from 6 bolt to 7 bolt I think in 92 so early 1Gs are 6 bolts, later 1Gs and 2gs had 7 bolts.

its for my spyder...i am looking for a block that will drop right in. so i didn't know if the spyder GS was the only block out there or did any other models use the 4G64
