do NOT buy from mantapart…
their reputation, is that of low quality, bad delivery and worse service.
i boosted my stock 2.4…
even built 2.4’s would not be as reliable as the eco…
the solstice uses a 2.4l eco engine…
the only way i would suggest the LD9 is if you already have one.
if you built one, and wanted around 200 hp… you could probably drive it that way forever. I would not expect any longevity if you go for 300+
