I will have to measure it again. You're not the only one that asks that lol.
As of right now, no tune. Garrett gt40 on 10psi, seems to be doing fine, but I do not get on it. Waiting for a buddy in Japan to source me a Apexi power fc. Ideally I would want aem, or ecu masters stand alone...but you know, limited only by money.
Anyway, here is my couplers. =)
Next parts I am getting is
Id1000 injectors
Aeromotive fpr
Bigger fuel lines
2x DW 350 inline fuel pumps
1x daul fuel pump holder
Fuel rail with an fitting welded in middle
And...a apexi pfc.
Should wake up this old 1jzgte. =)
