SR overheating= lean?

[kamikaze]

My car has an sr20 normal driving is ok but heavy load lets say i run the skidpad twice the tempeture raises very fast.
The fuel pressure is 50psi on idle and around 60-65 under boost.
AC has been removed and im using aluminum Koyo radiator with two electic fans

Also i install a regular(NOT wideband) autometer AF gauge and its always showing that im running lean.
Im boosting 8psi with a T28, megan manifold and fmic besides that is compete stock.

Since im not looking big numbers in hps what will be the best way to address this problem?
-Bigger injectors?
-SAFC (like neo)....but i will need wideband or Dyno money!
-faulty MAF?

Any1 has install the Nistune and have a real feed back as far as install and setup, that could be my solution?

Im in a budged so i need to spend my money wisely..........

Count on u guys:bigthumbu

running lean will cause you to run a little hotter but not that much

i had the same problem with my s13 with an rb..
it ended up being that the intercooler was blocking air flow to the rad..
i did a mid mount setup and never over heated again

yeah dr.dooms is right, if you really want to check your a/r ratio however invest in a wideband.
