are all the pins on the connectors and ecu the same for the functions that they are suppose to ruN? n how much should it cost me to have the ecu reprogramed?

 

Yes, but you will lose your secondaries.

 

nothing is wrong w/ losing secondaries.. you also look them w/ a skunk2 or ITR intake manifold..

 

Don't run it unless you are going to use a single butterfly intake manifold. The loss of the secondarys will hurt your low-end on a stock b18c1 because of too much airflow with the runners always open. I'm going to use a P28 ECU on my B18C1 with a Skunk2 I.M. it's been programed already and it was tested in a donor car and ran great. I paid $190 from Locash Joe Sawyer @ Hasport. It would have been $150 but I had him customize it a bit.

 

i have a skunk p28 ecu in my car with the skunk intake manifold. it works great, you can use the p28 with the stock gsr manifold but i wouldnt recomend it, like brokstar said your car will not run as it should. if you use the p28 then you should definatly get the skunk 2 manifold. also the type r manifold will not work because the bolt pattern is different.
