Early trucks ran 4G52's (Astron I 2.0L - it looks identical to the 4G54/4G54B/G54B). Some countries also got 4G32/4G32B's (Saturn 1.6L) and were in production the same time as the 4G52. So your engine will be a 4G54 variant. SubGothius has got this coveredOriginally Posted by Salteen
Only thing I would do is block the EGR gallery from the exhaust port and remove the EGR stuff altogether (keeping it all in place will be enough to make the casual observer think all of the anti-pollution stuff is still connected and operational) but that is because I am severely OCD and have a raging hatred for the anti-pollution crap. I completely ground off the EGR gallery on my intake and cut 50% of the valve mount off in preparation for a Weber swap on my G63B...
let me go ahead and clarify i did not use a fuel pump block off plate and i did use an egr block off plate and a single plane carb spacer.
