What temp t-stat did you get? I've seen 160F, 180F, and 195F offered for the 4G63. Maybe try going with a cooler one. Maybe you had a 160F or 180F before and now you have a 195F. Most of the parts stores carry the 180F ones, you'd most likely have to order a 160F.
EDIT: Looking at Rockauto.com, they carry 180F and 170F t-stats for your car, and they're around $10.
I dunno man, could be any number of things.
I have a tested working new 180* tstat. Don't want a 170 as I've heard they don't let the coolant sit in the block long enough leading to less heat transfer.. do have one of those pressure relief rad caps, I don't like it though so I am going to get a regular one now...along with new bpr7es NGKs.
Timing is set properly on 1g CAS. Car runs great. Doesn't seem to even push any coolant intothe bottle..
Thanks
